Parameter Name
247 Intermittent Pilot 0 0-1
Sets the type of pilot being used. If set to 1, the pilot valve will remain open from phase 40 to the end of
main operation (oP…).
0 = interrupted pilot
1 = intermittent pilot

Flame Failure Response
Time
(FFRT)
1 0-1
Sets the flame failure response time (FFRT). The FFRT is the maximum length of time that the flame signal
can go away before a lockout occurs. This setting also doubles as the length of time the signal from the air
pressure switch can go away before a lockout occurs. On PME73.840A1, the FFRT is fixed at 1 second.
0 = 1 second
1 = 3 seconds

257 Trial for Ignition
811 - 4.116 sec
812 - 4.116 sec
840 - 2.205 sec
0-13.23 sec
This setting defines the overlap of the spark (output X4-02.3) and the pilot valve (output X7-01.3) if a pilot
is used. The LME7 has a base time of 0.3 seconds. This setting adds seconds to the base time. Sets the
length of phase 40.

259 Actuator Opening Time
811 - 58.212 sec
812 - 58.212 sec
840 - 300.762 sec
0-1237 sec Set slightly longer than the time it takes for the actuator to drive from fully closed to fully open.

811 - 58.212 sec
812 - 58.212 sec
840 - 300.762 sec
0-1237 sec Set slightly longer than the time it takes for the actuator to drive from fully open to fully closed.

515.00
Actuator Purge
Position
1 0-1
Determines the position of the actuator during prepurge and postpurge. Note: This parameter is found at
the end of the 200 level parameters.
0 = Purge at low fire
1 = Purge at high fire
•
515.01 Actuator Activation 1 0-1
Used to activate or deactivate the use of an actuator. Note: This parameter is found at the end of the 200
level parameters.
0 = deactivated (no actuator)
1 = activated (with actuator)
•
654 Analog Input S 1 0-5
Sets the type of input signal being connected to terminal X65 or X5-03. This input signal is used to
determine the actuator position during operation.
0 = 3-position
1 = 0-10 VDC
2 = 0-135 Ohm
3 = 0-20 mA
4 = 4-20 mA with lockout when input is less than 4 mA
5 = 4-20 mA without lockout when input is less than 4 mA
