Safety Circuit Terminals 50 and 51, The Safety Circuit relay Terminals 50 and 51 is wired in the running interlock circuit of the Flame. Safeguard Control Terminals 3 and P of the FLAME MONITOR and D Series controls The safety. circuit relay is wired in series with any other running interlock circuit e g high and low water cut. off etc To help limit electrical noise frequencies the safety circuit relay should be the first circuit. wired in the running interlock circuit of the flame safeguard control Refer to diagram below See. SEQUENCE OF OPERATION HIGH AND LOW ALARM LIMITS section in Bulletin E 3401. WARNING An electro mechanical steam pressure or hot water high limit switch. MUST REMAIN in the running interlock circuit of the flame safeguard control. Operating Control Circuit Terminals 52 and 53, The Operating Control Terminals 52 and 53 is wired in the operating control circuit of the Flame.
Safeguard Control Terminals L1 and 13 of the FLAME MONITOR and D Series controls The. operating control is wired in series with any other operating control limit e g burner on off switch. The operating control should be the first circuit wired in the operating control circuit of the flame. safeguard control after the burner on off switch if applicable Terminals 52 and 53 should be. wired in the same location as the operating control would normally be found Refer to diagram. below See SEQUENCE OF OPERATION OPERATING CONTROL section in Bulletin E 3401. FLAME MONITOR E340,TERMINALS TERMINALS,P EXTERNAL 50. RUNNING E340,INTERLOCKS INTERNAL,13 OPERATING 52,120 VAC Neutral L2 Terminal 54. To insure proper voltage reference between the E340 and flame safeguard control Terminal 54 is. wired to the 120 VAC Neutral connection of the flame safeguard control Terminal L2 of the. FLAME MONITOR and D Series control,Main Fuel Valve Terminal 55. Terminal 55 is wired to the main fuel valve connection of the flame safeguard control Terminal 7 of. the FLAME MONITOR and D Series control,Fuel Selector Switch Terminals 56 57 and 58. The E340 has three line voltage inputs Terminals 56 57 and 58 to monitor the status of a fuel. selector switch that determines which pressure and temperature sensors the E340 control will moni. tor For example if the selector switch is in the position for Oil the E340 control will disregard the. high and low alarm limits for gas pressure, Note When Heavy Oil is selected both the Oil and Heavy Oil inputs must be made.
Note If the associated sensor is programmed as UNUSED the input is ignored. Note If fuel selection is not detected all inputs open E340 displays NONE for Fuel Selected the. E340 will remain at low fire,WIRING CONNECTIONS RIGHT TERMINAL BLOCK. Earth Ground Terminal 40, A good earth ground is essential in the proper operation of the E340 Control. Powering the Control 24 VAC Terminals 41 Hot and 42 Common.

24 VAC COMMON,Auxiliary Relay Terminal 44, The E340 has a low voltage output relay Terminal 44 internally connected to Terminal 41 which. can be programmed to operate according to a time of day schedule See SEQUENCE OF OPERA. TION PROGRAM ON section in Bulletin E 3401,Firing Rate Damper Motor Terminals 45 and 46. The E340 provides a 4 20mA analog output Terminals 45 and 46 to control a firing rate damper. motor in response to system demand See SEQUENCE OF OPERATION MODULATING CON. TROL section in Bulletin E 3401 This analog output controls the firing rate motor after the flame. safeguard control releases the firing rate motor to automatic control Terminals 10 and 11 of the. FLAME MONITOR made, The E340 can directly control a firing rate damper motor that will accept a 4 20mA control input sig. nal or control an industry standard 135 ohm slide wire firing rate damper motor by using a 4 20mA. to 135 ohm transducer These transducers are commercially available from a number of vendors. Terminal 45 is the positive reference for the 4 20mA output signal and Terminal 46 is the negative. Selectable 4 20mA Analog Output Terminals 47 and 48. The E340 provides a 4 20mA analog output Terminals 47 and 48 which allows the user to select. one of the five pressure or temperature sensors or command rate output to provide a 4 20mA output. signal that is directly proportional to the value of the selected sensor Terminal 47 is the positive ref. erence for the 4 20mA output signal and Terminal 48 is the negative reference The chart recorder. or similar device connected to these outputs should not have a maximum impedance greater than 750. 24 VAC COMMON,EXTERNAL EXTERNAL,L1 RUNNING OPERATING. 24 VAC INTERLOCKS LIMITS,S2 X 50 40,S1 P 51 41,B M 53 43 ALARM.
