2.0 Product Overview 2.1 General Description The General Monitors Model FMD (Figure 1) is a 4-digit LCD display module designed for use with General Monitors Models TS400, TS420, IR2100, and IR7000 Gas Detectors. It is available in an explosion-proof junction box for explosion-proof and general-purpose installations, and in a glass-reinforced polyester junction box for intrinsically safe, increased safety, and general-purpose installations. For intrinsically safe installations, the FMD is 4-20mA loop-powered and provides a local display for the TS400 and TS420 (Figure 1). The display range can be selected via a magnetically activated switch to match the sensor range on the TS400/TS420. The operational mode and gas concentration is displayed on the 4-digit display. For explosion-proof and general purpose installations, the FMD is +24VDC (nominal) powered. Optional relays provide output of warning, alarm and fault conditions at the sensor. Operating mode, display range, warning, and alarm set points are user-selectable via a magnetically activated switch. Relays are user-programmable as latching or non-latching, normally deenergized or normally energized. Latching relays can be reset via a remote reset input or via the magnetic switch. 2.2 Features and Benefits Figure 1: Field Mounted Display with TS400 Microprocessor-based electronics: Monitor fault conditions; sensor inputs and provide outputs in the form of display codes and relay contacts. Setup Mode: Allows the user to set parameters, such as, operating mode, display range, alarm set points, relay settings, etc. These parameters are viewed on the display during the setup mode. 3
Test Gas Mode: Allows the user to test the attached gas detector with the warning and alarm relays disabled. Program Review Mode: Allows verification of user programmable options. Protection Options: The Model FMD can be installed in either intrinsically safe or explosionproof installations providing maximum installation flexibility. 2.3 Applications The Model FMD is a 4-digit, field-mounted display for gas detection applications. Below is a partial list of applications: Refineries Drilling platforms and rigs Gas and oil production platforms Gas collection facilities LPG/LNG processing and storage Gas turbines Solvent vapors Chemical & petrochemical plants Paint spray booths Aircraft hangars 2.4 Display Assembly 2.4.1 Display Electronics The display electronics are contained within an encapsulated module that is mounted to the lid of the enclosure. A lanyard, connecting the lid and base of the enclosure, protects the module during installation, and simplifies field wiring. In the +24VDC-powered versions of the product, an on-board power supply produces all necessary voltages from the incoming +24VDC. In the loop-powered version, the on-board power supply produces the necessary voltages directly from the 4-20mA loop. The 4-20mA loop is monitored continuously by the microprocessor, which converts the incoming loop current to display values, depending on the selected display range and operating mode. Display range, operating mode, and warning and alarm set points can be programmed via the magnetic switch. All settings are stored in non-volatile memory and are retained if power is lost. 4
2.4.2 Enclosure Options The FMD is available in two enclosures. The explosion-proof enclosure (Figure 3) is provided to allow installation in hazardous areas where the protection method in the plant is explosionproof. The IR2100 and IR7000 require this enclosure since their outputs are not intrinsically safe. The explosion-proof enclosure can also be used to install the Model TS400 and TS420 in hazardous areas where the protection method is explosion proof. A zener barrier is mounted in the base of the enclosure to maintain the TS400 and TS420 intrinsically safe approvals. The polyester enclosure (Figure 2) is provided for intrinsically safe protected hazardous areas for the TS400 and TS420. The polyester enclosure can also be used for increased-safety installations of the IR2100/IR7000. NOTE: An explosion-proof conduit seal must be mounted to the TS400 or TS420 at the time of manufacture to maintain the explosion-proof approvals.

3.0 Installation 3.1 Upon Receipt of Equipment All equipment shipped by General Monitors is packaged in shock absorbing containers that provide considerable protection against physical damage. The contents should be carefully removed and checked against the packing slip. If any damage has occurred or if there is any discrepancy in the order, notify General Monitors as soon as possible. All subsequent correspondence with General Monitors must specify the equipment part and serial numbers. Each Model FMD is completely checked at the factory; however, a complete checkout is necessary upon initial installation and start up to ensure system integrity. 3.2 Display Location Considerations There are no standard rules for display placement, since the optimum location varies with each installation. The customer must evaluate conditions at the facility to make this determination. Some factors to consider when selecting a display location: Where possible, the display should be easily accessible for installation, viewing of the display, and periodic maintenance. Observe the operating temperature limits of both the Field Mounted Display and the attached gas detector. Locate the units away from concentrated sources of heat. Although the FMD is highly EMI/RFI resistant, it should not be mounted close to radio transmitters or similar equipment. 3.3 Installation For Use With Model TS400 or TS420 The three distinct installation methods when the Field Mounted Display is to be used with the Model TS400 or TS420 are described below. 3.3.1 Intrinsically-Safe Installation For intrinsically safe installations, the FMD must be mounted in the polyester housing. A safety barrier must be mounted in the non-hazardous area (control room) to maintain the intrinsicsafety approval of the system. NOTE: Refer to Section 6.1 for intrinsic-safety wiring requirements. For this installation, the TS400 or TS420 is connected in series with the Field Mounted Display in the loop-powered configuration. A labeled terminal block is provided in the enclosure for field wiring of the gas detector and the Field Mounted Display (Figure 4). 6
+24V FMD RED 45198-4 IE FMD WHT TS400 RED TS400 WHT GND Figure 4: Terminal Connections, Intrinsically Safe Wiring +24VDC power is routed through the customer supplied safety barrier in the control room, into the +24V terminal in the enclosure. The loop return line is routed through the negative side of the customer supplied safety barrier to the GND terminal in the enclosure. The TS400/TS420 Red and White leads are connected to the TS400 RED and TS400 WHT terminals in the enclosure respectively. The TS400 Green lead must be attached to the EARTH terminal in the enclosure. The Field Mounted Display Red and White leads are connected to the FMD RED and FMD WHT terminals in the enclosure respectively. See Figure 9, for an example of Field Wiring. 3.3.2 General Purpose Installation Without Relays For general-purpose installations without relays, the FMD can be connected as either a looppowered or a +24VDC powered system. In loop-powered systems, connect as described in Section 3.3.1. NOTE: The customer supplied safety barrier is not necessary in this installation. For +24VDC-powered systems, a three-conductor cable is required. +24VDC and Ground are connected to the terminals marked +24VDC and GND respectively (Figure 5). 7

The TS400/TS420 white lead and the FMD blue lead are connected to the terminal marked TS400 WHT/FMD BLU in the enclosure. The FMD brown lead is connected to the terminal marked FMD BRN. The FMD white lead is connected to the terminal marked FMD WHT in the enclosure. THE FMD black lead is connected to the terminal marked FMD BLK / FMD WHT in the enclosure. See Figure 10, for examples of Field Wiring. 3.3.3 General Purpose Installation With Relays For general-purpose installations with relays, the FMD must be connected as a +24VDCpowered system as described in Section 3.3.2. The terminal block provided for field wiring in the housing is different due to the need for additional terminals for the relay connections (Figure 6). The FMD wiring to the terminal block has been completed prior to shipment of the product. Field wiring is completed as follows: 1. Connect the +24VDC power supply and the TS400/420 Red lead to the terminal marked +24V. 2. Connect the +24VDC return line to the terminal marked GND. 3. Connect the TS400/420 white lead to the terminal marked AI. If the 4-20mA signal does not need to be monitored in the control room, jumper the terminal marked AO with the GND terminal. 4. If the 4-20mA signal must be monitored in the control room, connect the terminal marked AO to the wire connected to the 4-20mA signal-line in the control room. 8
Figure 6: Terminal Connections, General Purpose Installation, with Relays Connections for the relays are clearly marked on the base-plate inside the junction box (Figure 6). The labels for the alarm and warn relays are based on relay settings of normally deenergized. If either of these relays is configured as normally energized, the normally open (NO) and normally closed (NC) contacts must be reversed. The fault relay is configured at the factory as normally energized and cannot be changed. The labels for the relay contacts are based on this setting. See Figure 9, for an example of Field Wiring. WARNING: Inductive loads (bells, buzzers, relays, solenoids) must be clamped to avoid damage to the relays in the FMD. Unclamped inductive loads can cause voltage spikes in excess of 1000V.Refer to Figure 7for clamping requirements. Figure 7: Relay Protection Circuits for DC and AC loads 9
3.3.4 Explosion-proof Installation of Model TS400 or TS420 For explosion-proof installations, the TS400/TS420 must be ordered from the factory with the explosion-proof conduit seal installed and mounted in the explosion-proof enclosure. The TS400/420 and the FMD are shipped pre-wired in the housing. The TS400/420 wiring is done below the terminal board to TB4 (Figure 8) in the housing to separate the intrinsically safe wiring from the XP rated wiring above the terminal board. An included shunt-diode barrier is mounted in the base of the explosion-proof enclosure to protect the TS400/TS420 s intrinsically safe outputs. Field wiring to the control room must be explosion-proof rated. Field wiring is completed using the terminal blocks marked TB1 and TB2 in the junction box. A label is mounted to the lid of the junction box and terminals are clearly marked to help simplify field wiring. +24VDC NOMINAL +26VDC MAX.

4.4 Model IR2100 and IR7000 Calibration The field-mounted display simplifies field zeroing and calibration of the IR2100 and IR7000 by providing cues on the display for the operator. Please refer to the appropriate instruction manual for the gas detector being used for complete calibration instructions. To re-zero the gas detector or perform a complete gas calibration, apply the magnet to the GMI logo on the display cover. The display will show a set of horizontal bars for about 5 seconds. When the word clr appears on the display, remove the magnet. The display will now scroll through a set of options. When the word CAL is displayed, apply and remove the magnet. After a few seconds CAL will begin to flash, followed by a flashing AC on the display. The gas detector is now automatically re-zeroing. NOTE: For the Model IR7000, Nitrogen must be applied to the gas detector at the time of zeroing. Refer to the IR7000 Manual for instructions. After approximately 2 minutes, the display will show a non-flashing AC. This means that the zero operation is complete. If gas calibration is not required, simply wait 30 seconds and the gas detector and FMD will return to normal operation. NOTE: The CAL option is only available in IR2100 mode. If gas calibration is required, when the AC stops flashing, apply the magnet to the GMI logo again. The word CAL will be displayed for a few seconds, followed by a flashing CP. Apply the calibration gas as described in the instruction manual for the gas detector. After approximately 30 seconds, the display will show a non-flashing CP, which means the gas calibration is proceeding. When calibration is complete, the display will show CC. Remove the calibration gas. When the gas at the detector has fallen below 5% FS, the gas detector and FMD will return to normal operation. 4.5 Maintenance For routine maintenance for the attached gas detector please refer to the appropriate instruction manual. The field-mounted display requires no routine maintenance, with the exception that the display window may need to be cleaned occasionally, depending on the conditions at the installation site.
