3 RPM1600 Series Room Pressure Monitors Technical Bulletin How to Use This Technical Bulletin This technical bulletin describes how to operate, configure, calibrate, maintain, and troubleshoot the RPM1600 Series Room Pressure Monitors. This manual is divided into two parts. Part One: User Basics on page 4 describes the monitor and the user interface. This section applies to users, facilities staff, and anyone who requires a basic understanding of how the monitor operates. Part Two: Technical Section on page 9 describes the technical aspects of the monitor, which include operation, configuration, calibration, maintenance, and troubleshooting. This section applies to personnel who program or maintain the monitor. Read this manual thoroughly before changing any firmware settings or software items. Note: This technical bulletin assumes that the monitor has been properly installed. Refer to the RPM1600 Series Room Pressure Monitors Installation Instructions (Part No ) for information on properly installing the monitor. Safety Information This section gives instructions to promote safe and proper handling of RPM1600 Series Room Pressure Monitors. There are no user-serviceable parts inside the monitor. Opening the case voids the warranty. Refer all service of the unit to a qualified technician. Passcode RPM1600 Series Room Pressure Monitors have Passcodes to limit unauthorized access to the room mode or complete menu system. The access codes can be turned on or off through the Passcode menu item. When the monitor ships from the factory, it is configured with the access code off. See Configuration on page 9 for instructions on entering the access code. 3

4 Part One: User Basics This section is designed to provide a brief but thorough overview of the RPM1600 Series Room Pressure Monitors. These few pages explain the purpose and the operation of the monitor. Technical product information is available in Part Two: Technical Section on page 9. The Instrument The RPM1600 Series Room Pressure Monitors are designed to measure and report room pressure differentials in health-care facilities and other critical environments. Some models also can measure other parameters, such as supply flow, exhaust flow, relative humidity, and room temperature. Figure 1: Room Pressure Monitor Operator Panel The RPM1600 Series Room Pressure Monitors are easy to use. Room conditions (normal, alarm, no isolation) and room modes (Positive, Negative) appear on the LCD touch screen. You can configure the LCD touch screen to show the room pressure differential or all measurements. This section provides specific details about the LCD touch screen and controls. 4

5 Figure 2 and Figure 3 identify the important features on the LCD touch screen: Figure 2: Single Room Screen Figure 3: One Room with Anteroom Screen 5

6 LCD Touch Screen The LCD touch screen is highly configurable. It can display critical information, including pressure differential, flow rate, alarm status, menu options, and error messages. Use the LCD touch screen to program the device to display menus, menu items, and current value of the menu item. Table 1: Room Indicator Colors Color Definition Green Red Gray 1 The screen icon is colored green (NORMAL) when the room pressure and/or other configured measurements are adequate. This light indicates that the room is operating safely. If a setpoint cannot be maintained or an alarm limit has been reached, the green light turns off, and the red alarm light turns on. The room icon is colored red (ALARM) when the room pressure or other configured measurements exceed alarm limits. This light indicates the room is not operating safely. The display screen also indicates the type of alarm or an emergency message. The room icon is colored gray to indicate No Isolation mode. In No Isolation mode, the RPM1600 Series Monitors do not alarm. 1. Due to the blue screen, gray icons appear blue in digital images. These operator keys appear on the LCD touch screen: Table 2: Operator Keys Key Graphic Key Name Key Function MUTE The MUTE key silences an audible alarm. The alarm remains silent until the MUTE TIME value has been reached or the measurement returns to the control setpoint. ACKNOWLEDGE The ACKNOWLEDGE key stops visual and audible alarms. If you want to enable this feature, set the ALARM RESET item to LATCHED. (See Table 6 on page 22.) Alarms The RPM1600 Series Room Pressure Monitors use visual and audible alarms when room conditions exceed the alarm setpoints. When the room conditions are safely within the field-configured parameters, no alarms sound and the room icons on the LCD touch screen remain green. The alarms activate if the room pressure differential (or airflow) becomes too low or too high. The safe range for room pressure differential is in. W.C. (50 cfm) above the low alarm setpoint and in. W.C. (50 cfm) below the high alarm setpoint. You can program the audible and visual alarms to do one of the following: automatically turn off when the room pressure differential (or airflow) returns to the safe range stay in alarm until the key is pressed (see menu item ALARM RESET) 6

7 Example: Figure 4: Alarm Example for Negative Room Mode Low Alarm (higher pressure, less negative) Normal (safe range) Negative Low Alarm Setpoint High Alarm (lower pressure, more negative) Negative High Alarm Setpoint When a room is set to Negative mode, the low and high alarms are Neg Low Alm and Neg Hi Alm. The normal differential pressure range (safe zone) is between the Neg Low Alm and Neg Hi Alm setpoints. Table 3: Alarms and Differential Pressure Alarm Action Low Alarm High Alarm Alarm Setpoint in. W.C in. W.C. Alarm Activates < in. W.C. > in. W.C. Alarm Deactivates in. W.C in. W.C. Notes: Optional flow monitors are required for airflow alarms. Depending on the organization of your safety staff, the people who determine the parameters and the alarm setpoints may be in an Engineering, Industrial Hygiene, or Facilities group. Visual Alarm If an alarm condition occurs in a room, that room s icon on the LCD touch screen changes to red. The room icon remains red as long as that alarm condition remains. See Table 1 for an explanation of room icon colors. Audible Alarms The audible alarm is continuously on in all low and high alarm conditions, as long as that alarm condition remains. Press the key to silence the audible alarm. If the audible alarm has been muted, the alarm is silenced for a configurable period of time (see menu item MUTE TIME) or when the measurement returns to the safe range. The safe range is in. W.C. (50 cfm) above the low alarm setpoint and in. W.C. (50 cfm) below the high alarm setpoint. The audible and visual alarms can be programmed to either automatically turn off when the unit returns to the safe range or to stay in alarm until the key is pressed (see menu item ALARM RESET). Alarm Relays The monitor uses two alarm relays. The alarm relays open or close to indicate an alarm condition, according to programmed settings. The alarm relays close on loss of power. 7

8 Relay 1 (low alarm relay) activates after the alarm delay for the following alarms: low pressure low flow low temperature low RH Relay 1 activates immediately if either of the following occurs: a linear output module (LOM) alarm low pressure drop across a Venturi valve (if a flow input is configured for Venturi valves) Relay 2 is field-configurable to function as a high alarm relay or to indicate the room status. See the Relay 2 Out item in the Alarm Config menu (see Table 6 on page 22) for details on this operation. 8

9 Part Two: Technical Section The RPM1600 Series Monitors are ready to use after they are properly installed and configured. The thermal anemometer (TA) sensor is factory-calibrated, as are most differential pressure transducers (DPTs). Figure 1 on page 4 shows the Room Pressure Monitor (RPM), which is programmed with a default configuration that can be easily modified to fit your application. The technical section is separated into five parts that cover all aspects of the RPM. Each section is written as independently as possible. 1. Configuration on page 9 explains the programming keys, the programming sequence, and how to program the RPM. 2. Menus and Menu Items on page 17 lists all of the firmware items, some of which are available to program and change. The items are grouped by menu, which means that all setpoints are in one menu, all control signal items in another menu, and so on. The menu items include programming name, description of menu item, range of programmable values, and the default value (factory-set value). 3. Calibration on page 48 describes the required procedure to calibrate the RPM. This section explains how to compare the RPM s reading to a portable thermal anemometer and then adjust the span to establish an accurate calibration. This section also describes how to zero a flow station transducer (if installed). 4. Maintenance and Repair Parts on page 52 covers all routine maintenance of equipment, along with a list of repair parts. 5. Troubleshooting on page 54 describes how to diagnose and resolve mechanical or performance problems. Configuration Configuring the RPM1600 Series Room Pressure Monitor is quick and easy if you follow the proper keystroke procedure. This section covers how to configure the monitor through the LCD touch screen. IMPORTANT: The RPM1600 Series monitor continues operating during configuration. When you change the value of a menu item, the new value takes effect immediately after saving the change. You can configure the RPM1600 Series monitors by using either of the two methods: Local Configuration Method (uses only the LCD touch screen) Combined Configuration Method (uses the LCD touch screen and BACnet MS/TP network communications) Note: If you use the Combined Configuration Method, use the host computer s procedure (see Appendix B: Network Communications on page 63). 9

27 Alarm Constraints The following constraints may prohibit you from incorrectly adjusting the setpoints: 1. Room mode. The positive pressure alarms are only active when positive control is selected. Negative pressure alarms are only active when negative control is selected. In No Isolation mode, all alarms are turned off. 2. The monitor is programmed with deadbands between alarm setpoints to prevent the controller from cycling between high and low alarms due to normal fluctuations. Setpoint deadbands are: Pressure = in. W.C. Flow = 50 cfm Temperature = 1 F Relative Humidity = 1% Position = 1% Open Example: The control NEG LOW ALM is set at in. W.C. The NEG HI ALM cannot be set less negative than in. W.C. 3. Alarms do not terminate until the room pressure slightly exceeds the alarm setpoint. 4. The ALARM RESET item selects how the alarms terminate when the controller returns to the safe range. The pressure and flow alarms all terminate the same; either latched or unlatched. If unlatched is selected, the alarms automatically turn off when the value slightly exceeds the alarm setpoint. If latched is selected, the alarms do not terminate until the pressure or flow exceeds the alarm setpoint and the key is pressed. 5. A programmable ALARM DELAY determines how long to delay before activating the alarms. This delay affects all alarms, pressure, and flow. 6. The MUTE TIME item temporarily turns the audible alarm off for all pressure and flow alarms. 7. The display can only show one alarm message. Therefore, the monitor has an alarm priority system, with the highest priority alarm being displayed. If multiple alarms exist, the lower priority alarms do not display until after the highest priority alarm has been eliminated. The alarm priority is as follows: a. Room 1 pressure sensor low alarm b. Room 1 pressure sensor high alarm c. Room 1 minimum exhaust flow d. Room 1 minimum supply flow e. Room 1 temperature alarms f. Room 1 relative humidity alarms g. Room 1 supply Venturi (low static pressure) alarm h. Room 1 exhaust Venturi (low static pressure) alarm i. Anteroom pressure sensor low alarm j. Anteroom pressure sensor high alarm k. Room 2 pressure sensor low alarm l. Room 2 pressure sensor high alarm m. Room 1 supply airflow-proving switch n. Room 1 exhaust airflow-proving switch 27

28 8. The low and high alarms are absolute values. Figure 25 shows how the values must be programmed in order to operate correctly. The value of each setpoint or alarm is not important (except for small dead band) in the following graph. It is important to understand that the high alarm is a greater negative (positive) value than the low alarm. Figure 25: Low and High Alarm Values -0.2 in. W.C.

48 Calibration The calibration section explains how to calibrate the RPM1600 Series Monitor and how to zero a flow station pressure transducer (optional). A warning message appears if the RPM1600 Series Monitor has not been calibrated. Note: This section assumes that the appropriate sensor has been correctly installed. Inaccurate readings may be detected if a sensor is not installed correctly. Review the Installation Instructions and verify that the sensor is installed correctly (this is usually only a problem on initial setup). Reference measurements from a capture hood are required to calibrate the monitors. IMPORTANT: The RPM1600 monitor is disabled during calibration. Alarms do not function to warn of unsafe conditions. To begin the calibration process, enter the appropriate INPUT# CONFIGURE menu (see Configuration on page 9 if not familiar with keystroke procedure). Room Pressure Calibration You can measure room pressure by using either a thermal anemometer (TA) sensor or a differential pressure transducer (DPT). Calibrating to the TA Sensor Note: The TA sensor is calibrated at the factory and does not normally need adjustment when installed. 1. Select SENSOR SPAN item. (See Table 12 on page 30, Table 14 on page 31, Table 25 on page 41, or Table 26 on page 41.) 2. Position a thermal anemometer (or other instrument configured to measure air velocity) in the door opening to obtain a velocity reading. Take a measurement of the air velocity entering or exiting the door. 3. Input the reference measurement from Step 2 into the monitor. 4. Save the reading and exit the menu system. Calibrating to the Differential Pressure Transducer Note: This calibration process configures the monitor to match the reading from the DPT. If the DPT itself needs to be calibrated, refer to the instructions that come with the DPT. 1. Write down the output signal range and pressure range of the DPT. As an example for these instructions, assume the DPT has an output signal range of 0 to 10V and a pressure range of to in. W.C. 2. Select the SENSOR MIN item and enter the minimum pressure range of the DPT. In this example, enter in. W.C. 3. Select the SENSOR MAX item and enter the maximum pressure range of the DPT. In this example, enter in. W.C. 4. Select the SIGNAL MIN item and enter the minimum output signal of the DPT. In this example, enter 0 V. 5. Select the SIGNAL MAX item and enter the maximum output signal of the DPT. In this example, enter 10 V. 6. To zero the DPT: a. Mark the high pressure tubing going to the high port of the DPT. b. Remove the tubing from the high and low ports of the DPT. c. Enter the SENSOR ZERO item on the controller. 48

49 d. Reconnect tubing to the high and low ports of the DPT, using the mark to connect the high pressure tubing to the high port. Flow Calibration Flow can be measured using a one of the following options: airflow measuring station with differential pressure transducer linear electronic airflow measuring station Venturi valve with feedback. Airflow Measuring Station with Differential Pressure Transducer Calibration Note: Flow stations are optional and may not be installed in your system. 1. Set DUCT AREA item to the duct area where the flow is measured. 2. Zero the flow station: a. Mark the high pressure tubing going to the high port of the DPT. b. Remove the tubing from the high and low ports of the DPT. c. Enter the Sensor Zero item on the monitor. d. Reconnect the tubing to the high and low ports of the DPT, using the mark to connect the high pressure tubing to the high port. 3. Enter the LOW CAL menu to perform the low flow calibration related to the following items: VOLTAGE INPUT: Current voltage from DPT UNCALIBRATED FLOW: Current flow rate ZERO VOLTAGE: Voltage from DPT output from Step 2 CALIBRATED FLOW: Input actual flow as measured with reference instrument here a. Adjust the flow to its minimum volume. Observe the VOLTAGE INPUT displayed on the screen, or use a voltmeter to read the voltage at the pressure input terminals on the back of the monitor. b. Slowly increase the flow until the VOLTAGE INPUT (DPT output) shows the first noticeable increase in voltage from the minimum flow. A general rule-of-thumb is that the voltage change should occur with the damper between 10% to 30% open. c. For reference only, the UNCALIBRATED FLOW item displays the default measured flow based on the current settings of the flow station (for example, duct area). d. Determine the actual flow with a duct traverse or other reference measurement. e. Enter the actual flow measurement under the CALIBRATED FLOW menu item. f. Press the Save key to save the flow data. The low flow calibration is complete. 4. Enter the HIGH CAL menu to perform the high flow calibration related to the following items: VOLTAGE INPUT: Current voltage from pressure transducer UNCALIBRATED FLOW: Current flow rate ZERO VOLTAGE: Voltage from DPT output from Step 2 CALIBRATED FLOW: Input actual flow as measured with reference instrument here a. Adjust the flow to its maximum volume. Observe the VOLTAGE INPUT displayed on the screen, or use a voltmeter to read the voltage at the pressure input terminals on the back of the controller. 49

50 b. Slowly decrease the flow until the VOLTAGE INPUT (DPT output) shows the first noticeable decrease in voltage from the minimum flow. c. For reference only, the UNCALIBRATED FLOW item displays the default measured flow based on the current settings of the flow station (for example, duct area). d. Determine the actual flow with a duct traverse or other reference measurement. e. Enter the actual flow measurement under the CALIBRATED FLOW menu item. f. Press the Save key to save the flow data. The high flow calibration is complete. Note: Use Balance Flow to verify flow station calibration and adjust the K-FACTOR. Linear Electronic Airflow Measuring Station Calibration Note: Flow stations are optional and may not be installed in your system. 1. Set DUCT AREA to the duct area at the linear flow station location. 2. Set SENSOR MAX to match the upper limit of the velocity that the sensor on the linear flow station can measure. 3. Set SIGNAL MIN to match the minimum voltage output (0 to 10 V) of the linear flow station (typically 0 V). 4. Set SIGNAL MAX to match the maximum voltage output (0 to 10 V) of the linear flow station (typically 10 V). 5. Exit the menu. Note: Use Balance Flow to verify flow station calibration and adjust the K-FACTOR. Venturi Valve with Feedback Calibration Note: Linear Output Module (LOM) Venturi Valves are optional and may not be installed in your system. 1. Obtain the Venturi valve minimum and maximum flow, either by reading the label on the Venturi valve or by performing duct traverses when the Venturi valve is fully closed and fully opened. 2. Set MIN FLOW to the minimum Venturi valve flow. 3. Set MAX FLOW to the maximum Venturi valve flow. 4. Exit the menu. Note: Use Balance Flow to verify Venturi with Feedback calibration and adjust the K-FACTOR. Supply/Exhaust Switch Calibration Note: Flow switches are optional and may not be installed in your system. Flow switches do not actually measure the flow, but are designed to provide an open or closed signal to indicate the presence or absence of flow. Set the LOW FLOW SIG to match the low flow indication from the switch. OPEN means the switch opens to indicate low flow. CLOSED means the switch closes to indicate low flow. 50

51 Door Switch Configuration Note: Door switches are optional and may not be installed in your system. Set the DR OPEN SIGN to match the door open indication from the switch. OPEN means the switch opens to indicate the door is open. CLOSED means the switch closes to indicate the door is open. Temperature Sensor Configuration Note: Temperature sensors are optional. Only 1000 ohm Platinum RTD elements are supported by this device. After you connect the 1000 ohm Platinum RTD element to the RPM1600 Series Monitor, you must use an accurate temperature device as a temperature reference when you calibrate the 1000 ohm Platinum RTD. Use the RPM menu system to access the specific input to which the 1000 ohm Platinum RTD is connected. Adjust the SENSOR SPAN so the displayed temperature matches the reference temperature measurement. This applies a slight offset to the unit s temperature reading, which compensates for any error in the temperature reading of the platinum element. If you need to reset the SENSOR SPAN back to the factory default, use the RESET CAL function. Relative Humidity Sensor Configuration Note: Relative Humidity sensors are optional and may not be installed in your system. 1. Set the SENSOR MIN to the minimum reading of the relative humidity sensor. This is usually 0%. 2. Set the SENSOR MAX to the maximum reading of the relative humidity sensor. This is usually 100%. 3. Set the SIGNAL MAX to the minimum output voltage of the relative humidity sensor. This is usually 0 V. 4. Set the SIGNAL MAX to the maximum output voltage of the relative humidity sensor. This is usually 10 V. 5. Adjust the SENSOR SPAN so the displayed relative humidity matches a reference measurement. Use the RESET CAL item to reset the SENSOR SPAN back to the factory default. Occupancy Sensor Configuration Note: Occupancy switches are optional and may not be installed in your system. Set the UNOCC SIG to match the occupancy indication from the switch. OPEN means the switch opens to indicate the room is unoccupied. CLOSED means the switch closes to indicate the room is unoccupied. 51

52 Maintenance and Repair Parts The RPM1600 Series Room Pressure Monitors require minimal maintenance. Periodically inspect the system components and clean the pressure sensors to ensure that the monitor is operating properly. System Component Inspection Periodically inspect the differential pressure transducer (DPT) or the Thermal Anemometer (TA) sensor for accumulation of contaminants. The frequency of these inspections depends upon the quality of the air being drawn across the sensor. If the air is dirty, the sensors require more frequent inspection and cleaning. Slide open the cover (Figure 26) and visually inspect the TA sensor. The airflow orifice should be free of obstructions. The small ceramic-coated sensors (not shown) protruding from the orifice wall should be white and free of accumulated debris. Figure 26: TA Sensor Orientation (Left) and Dimensions (Right) Proper Orientation On Wall Pressure Sensor Base Dimensions 4-1/4 in. (108 mm) 3-1/4 in. (83 mm) 3-3/16 in.

(57 mm) Tube Hole Periodically inspect the other system components for proper performance and physical signs of excessive wear. TA Sensor Cleaning Remove accumulations of dust or dirt with a dry soft-bristled brush (such as an artist's brush). If necessary, you can use water, alcohol, acetone, or trichlorethane as a solvent to remove other contaminants. Use extreme care when cleaning the velocity sensors. The ceramic sensor may break if you: apply excessive pressure scrape the sensor to remove contaminants allow the cleaning apparatus to abruptly impact the sensor IMPORTANT: Pressure Monitor. If you are using a liquid to clean the sensor, turn off power to the RPM1600 Series Room Do not use compressed air to clean the velocity sensors. Do not attempt to scrape contaminants from the velocity sensors. The velocity sensors are quite durable; however, scraping may cause mechanical damage and possibly break the sensor. Mechanical damage due to scraping voids the pressure sensor warranty. Display Screen Cleaning Remove accumulations of dust or dirt with a dry soft cloth. If necessary, use isopropyl or ethyl alcohol to remove other contaminants. 52

54 Troubleshooting The RPM1600 Series Room Pressure Monitors are designed to be trouble-free; however, installation errors or interaction with other HVAC components may cause system problems. The system is easy to troubleshoot if you use an organized approach to evaluate the system. Troubleshooting is broken down into hardware (mechanical) and software problems. Hardware problems include wiring problems, incorrectly installed equipment, and add-ons or non-johnson Controls equipment. Software problems include control problems, configuration problems, or interaction problems with the HVAC system. The hardware test determines if all Johnson Controls mechanical components are functioning correctly. The hardware test accesses the diagnostics menu items. If you are unfamiliar with the controller menus, see Configuration on page 9 for the keystroke procedure. You can quickly resolve the majority of problems if you troubleshoot the hardware first. Consider disconnecting any non-johnson Controls components before you begin troubleshooting the hardware. Complete the procedures in Hardware Troubleshooting to confirm that all Johnson Controls hardware is operating correctly. If these procedures do not resolve the problem, see Hardware and Software Troubleshooting on page 57. Select the problem that most closely resembles your problem, review the possible symptoms, and perform any required corrective action. Note: Separating Johnson Controls system problems from the laboratory HVAC system can be difficult. Software or system performance problems can be affected by (and can affect) the supply air system, exhaust air system, or physical configuration of the room. Hardware Troubleshooting Perform these three steps to determine that all hardware is functioning correctly: 1. Confirm correct wiring. 2. Confirm correct physical installation. 3. Verify mechanical components. Confirm Correct Wiring Closely check the wiring to verify that it exactly matches the wiring diagram. Wiring diagrams are located in Appendix C: Wiring Information on page 75 of this manual. Closely check the wiring associated with non-johnson Controls components for correct installation. Consider disconnecting any non-johnson Controls components before you begin troubleshooting the hardware. The most common problem with installed hardware is incorrect wiring. This problem may exist on initial installation, or it may occur when modifications to the system take place. Confirm Correct Physical Installation Verify the physical installation of the hardware components when you check the wiring. Review the installation instructions and verify that all of the components are correctly located and installed correctly. Verify Mechanical Components Use the tests in this section to verify that mechanical components connected to the RPM are operating correctly. Test the RPM s analog outputs and relay outputs first. Then use the Diagnostic menu to test each component (inputs and outputs). Note: These tests require power to the RPM and any connected devices, so if an RPM has no power, see Table 36 on page 57 to eliminate the power problem. 54

55 Test Analog Outputs Enter the Analog Outpt item in the Diagnostics menu to manually manipulate the analog outputs. Figure 27: Analog Outputs Screen in Diagnostics Menu Tap Output 1, Output 2, or Output 3 to manually set the output signal. Test Relay Outputs Enter the Relay Outputs item in the Diagnostics menu to manually manipulate the relay outputs. Figure 28: Relay Outputs Screen in Diagnostics Menu Tap Relay 1 Toggle or Relay 2 Toggle to manually open or close the relay. Test - View Inputs Enter the View Inputs item in the Diagnostics menu to view all inputs with real-time updates. Figure 29: View Inputs Screen in Diagnostics Menu 55

56 The LCD screen displays None for any inputs that have not been configured. Go to the Configure menu to configure these inputs appropriately. Test - View Outputs Enter the View Outputs item in the Diagnostics menu to view all output signals with real-time updates. Figure 30: View Outputs Screen in Diagnostics Menu The LCD screen displays None for any outputs that have not been configured. Go to the Alarm Configure menu and the Interface menu to configure these outputs appropriately. If the RPM1600 Series Room Pressure Monitor passes each of the tests, the mechanical parts of the system are functioning correctly. See Table 36 on page 57 for further troubleshooting information. 56
