7 R0G,L,M BURNER CONTROL MODULES Location Humidity Install the relay module where the relative humidity never reaches the saturation point. The relay module is designed to operate in a maximum percent relative humidity continuous, noncondensing moisture environment. Condensing moisture may cause a safety shutdown. Vibration Do not install the relay module where it could be subjected to vibration in excess of 0.G continuous maximum vibration. Weather The relay module is not designed to be weathertight. When installed outdoors, protect the relay module using an approved weathertight enclosure. Final Wiring Check. Check the power supply circuit. The voltage and frequency tolerance must match those of the R0. A separate power supply circuit may be required for the R0. Add the required disconnect means and overload protection.. Check all wiring circuits and complete the Static Checkout, Table, before installing the R0 on the subbase.. Install all electrical connectors.. Restore power to the panel. Service Notes: Per industry standards, a conduit seal or a cable type that is sealed is required to be installed in a device that can result in flammable gas or flammable liquid flow through a conduit or cable to an electrical ignition source in the event of a seal leakage or diaphragm failure. This could be on the gas valves, or gas or oil pressure regulators. Check the Q0 Wiring Subbase terminals against the typical wiring drawings, Figures,,,,, or. If wires are attached to terminals that are unused in the figures, DO NOT INSTALL THE R0 until you have identified the connections functions. Most likely the old subbase terminals were used as tie points, so removing the wires, capping with a wire nut, and tucking the wire down into the subbase is all that needs to be done. Make sure the wiring subbase of the old device is a 0-terminal Q0 (four rows of terminals). Make sure the system Controller is connected to the correct terminal on the Q0 wiring subbase. It may be in a wire nut tucked into the subbase. It needs to be connected to a terminal (like terminal or ). Make sure there is an electrical service ground wire connection to the G terminal in the wiring subbase. R0G or BC000 with PM0G replacement. If the application was a dual burner ignition, check the Q0 subbase for a jumper between terminals to, discard the jumper and move the main valve connection (terminal ) to terminal. Replacing GP0 or GP0 devices: High Fire (or Purge Rate) Switch may be connected to terminal D. Identify, remove, and connect to terminal M. Replacing GP0 devices: Check wiring subbase. If D is jumpered to, remove the jumper. Replacing R0 programmers on Carlin 00 and 0 burners: Remove jumper from to. Remove jumper from to and wire nut the wires together. Note: There will be no wire on terminal. R0M replacements: Check terminal of the Q0 wiring subbase. If nothing is on, install the new R0M00. If is jumpered to, remove the jumper and install R0M00. If goes somewhere (assume a low fire switch because the system has a damper motor), remove J and J from the back of the R0M00. NOTE: J and J provide an input for the R0M when the system does not have a spring return damper with a low fire switch. Leaving J and J in place with either jumpered to or with the low fire switch will cause the blower motor to come on after the R0M is installed and power is supplied to the system. Generally, the following table will apply to select the R0M00 model and the status of jumpers J and J. - 0

OPERATION Sequence of Operation The R0 has the following operating sequences; see Fig., 9, and. The R0 LED provides positive visual indication of the program sequence: POWER,,, MAIN and. (Note: The Power LED is lit for / seconds and off for / seconds, to indicate normal operation.) Initiate The R0 enters the INITIATE sequence when the Relay Module is powered. The R0 can also enter the INITIATE sequence if the Relay Module verifies voltage fluctuations of +0/- percent or frequency fluctuations of ±0 percent during any part of the operating sequence. The INITIATE sequence lasts for ten seconds unless the voltage or frequency tolerances are not met. When the tolerances are not met, a hold condition is initiated for at least five seconds. When the tolerances are met, the INITIATE sequence restarts. If the condition is not corrected and the hold condition exists for four minutes, the R0 locks out. Causes for hold conditions in the INITIATE sequence: a. AC line dropout is detected. b. AC line noise prevents a sufficient reading of the line voltage inputs. c. Low line voltage brownouts occur. The INITIATE sequence also delays the burner motor starter from being energized and de-energized from an intermittent AC line input or control input. Standby The R0 is ready to start an operating sequence when the operating control determines a call for heat is present. The burner switch, limits, operating control and all microcomputer monitored circuits must be in the correct state for the R0 to continue into the PREPURGE sequence. - 0

24 R0G,L,M BURNER CONTROL MODULES Normal Start-Up Pre-Purge The R0 provides a pre-purge timing selectable from two seconds to 0 minutes with power applied and the R0 operating control indicating a call for heat: NOTE: NOTE: a. Running Interlocks, Pre-Ignition Interlocks, Burner Switch, Run/Test Switch, Lockout Interlocks and all microcomputer monitored circuits must be in the correct operating state. b. The blower motor output, terminal, is powered to start the PREPURGE sequence. The PREPURGE timing for the R0L does not begin until the High Fire Switch is closed. A jumpered High Fire Switch adds a 0-second hold before the purge time starts. c. The Pre-Ignition Interlock input must remain closed throughout PREPURGE; otherwise, control returns to the STANDBY state and holds (0 seconds) for the R0G,M or safety shutdown for the R0L occurs. d. The Lockout Interlock or Running Interlock inputs (interlock circuit including Airflow Switch) must close by ten seconds into PREPURGE; otherwise, a recycle to the beginning of PREPURGE for the R0G,M will happen or a safety shutdown for the R0L occurs. e. When PREPURGE timing is complete, the firing rate motor drives to the low fire position. If a damper motor is used (R0M), jumpers J and J should be removed from R0 subbase. f. When the firing rate motor reaches low fire position, the Low Fire Switch, terminal, is energized to enter the Ignition Trial state. A 0-second hold occurs for a jumpered Low Fire Switch before the ignition trial period begins. Ignition Trials. Pilot Flame Establishing Period (PFEP): a. With the firing rate motor at the low fire position: () The pilot valve and ignition transformer, terminals,, and, are energized. (a)the R0G has an interrupted or intermittent pilot valve, terminal, depending on the selection of configuration jumper. (b) The R0L has a -second interrupted pilot valve, terminal. (c)the R0M has an intermittent pilot valve, terminal. NOTE: All of the R0s have a ten-second interrupted pilot valve/ignition, terminal. () During PFEP, the Low Fire Switch must remain closed. If it opens, a safety shutdown occurs. () The Pre-Ignition Interlock input is ignored throughout the Ignition Trial state. b. Flame must be proven by the end of the 0-second PFEP (four if JR is clipped) to allow the sequence to continue. If flame is not proven by the end of PFEP, a safety shutdown occurs. c. After five seconds, the ignition, terminal, is de-energized for early spark termination.. Main Flame Establishing Period (MFEP): a. Terminal is energized when the presence of flame is verified at the end of a 0-second Pilot Flame Establishing Period (PFEP) (four seconds if JR is clipped). b. Terminal is turned off 0 seconds after terminal is energized. c. Terminal action: () R0L: De-energized seconds after terminal is energized. () R0G: (a)not turned off, or (b) seconds after terminal is energized and JR is clipped, or (c)0 seconds after terminal is energized and terminals and are jumpered and jumper JR is clipped. () R0M: Remain energized as long as call for heat is present. Run. Fifteen seconds after the main valve terminal is energized and flame is maintained, the R0 goes to Run.. The firing rate motor releases to modulation (R0G,L). Damper motor is energized (R0M).. The R0 is now in RUN and remains in RUN until the controller input, terminal or (model dependent), opens, indicating that the demand is satisfied or a limit opened. Postpurge The R0 provides a -second POSTPURGE following the completion of the RUN period (call for heat ends). The blower motor output remains powered to drive all products of combustion and any unburned fuel from the combustion chamber. It also supplies combustion air to burn fuel being purged from the fuel line downstream of the fuel shutoff valve.. The main fuel valve and intermittent pilot valve, terminals and, are de-energized and the firing rate motor is commanded to the low fire position to begin the POSTPURGE period.. After the -second POSTPURGE period is completed, the blower motor (terminal ) is de-energized and the R0 reenters Standby. Run/Test Switch WARNING Explosion Hazard. Can cause serious injury or death. Do not use the Run/Test switch during the Pilot Flame Establishing Period for the R0 when using Direct Spark Function, because it turns on the main gas valve, causing an accumulation of fuel in the burner. The Run/Test Switch is located on the top side of the R0, see Fig.. The Run/Test Switch allows the burner sequence to be altered as follows: - 0

25 R0G,L,M BURNER CONTROL MODULES. In Pre-Purge Drive To High Fire Position (R0L), the Run/Test Switch, when placed in the TEST position, holds in PREPURGE with the firing rate motor in the High Fire position.. In the measured PREPURGE sequence, the Run/Test Switch, when placed in the TEST position, causes the PREPURGE timing to stop. The firing rate motor is in the High Fire position.. In Pre-Purge Drive to Low Fire position, the Run/Test Switch, when placed in the TEST position, holds the burner sequence in PREPURGE with the firing rate motor in the Low Fire position.. In PFEP, the Run/Test Switch, when placed in the TEST position, stops the timer during the first seconds when a 0-second PFEP is selected or during the first seconds when a -second PFEP is selected, allowing pilot-turndown test and other burner adjustments to be made. This activates a -second flameout timer that permits pilot flame adjustment without nuisance safety shutdowns. The Run/Test Switch is ignored during PFEP for the R0L if terminals and or and are jumpered.. During Run, the Run/Test Switch, when placed in the TEST position, drives the firing rate motor to the Low Fire position. SETTINGS AND ADJUSTMENTS Selectable Site-Configurable Jumpers The R0 has three site-configurable jumper options; see Fig. 9 and Table. If necessary, clip the site-configurable jumpers with side cutters and remove the resistors from the Relay Module. The R0M has two additional jumpers located on the back of the chassis. These must be cut if a spring return damper motor is used. SELECTABLE CONFIGURATION JUMPERS RUN/TEST SWITCH NOTE: When R0 is switched to the Test mode, it stops and holds at the next Run/Test Switch point in the operating sequence. Make sure that the Run/Test Switch is in the RUN position before leaving the installation. Table. Site Configurable Jumper Options. NOTE: CONFIGURATION JUMPERS SHOWN FOR RM00G/RM0G. M0 Fig. 9.
