Accepts standard UV, self-check UV, or self-check IR scanners and/or flame rods
Integral LED display
Programmable purge times and safety times
Programmable actuator positions for purge, ignition, and low fire
Adjustable time overlap of spark ignition and pilot valve
Adjustable time overlap of the pilot and main gas valves
Proof-of-closure (POC) switch monitoring
Modbus RTU or BACnet MS/TP communication
Optional gas valve proving function
Password-protected access to OEM parameters
Integrated actuator control
Integrated PWM blower control

Base Unit

You will require one of the LME7 base units:

LME71.0001A1	Flame safeguard, without actuator control, without self-check scanner capability, 110V
LME73.0001A1	Flame safeguard, with actuator control, without self-check scanner capability, 110V
LME75.0001A1	Flame safeguard, with actuator control, with self-check scanner capability, 110V

Program Module

Choose one of the following PME7 program modules. The program module contains the program sequence used to operate the burner.
