Meaning for the LMV5x system
Fault with devices or wiring connected to the Base Unit (LMV5)
PS(M)-VP (Pressure Switch Valve Proving) has detected
pressure between the gas valves during the atmospheric test.
Switch opened when should have been closed.
PS(M)-VP (Pressure Switch Valve Proving) has detected the
absence of pressure between the gas valves during the
pressure test. Switch closed when should have been open.
Low oil pressure switch is closed when oil pump is not running.
Low oil pressure switch is open when oil pump is running.
High Oil Pressure switch is open.
Switches wired to the start release oil terminal (typically the
atomizing media PS) are not closed when anticipated
Switches wired to the direct start heavy oil terminal are not
closed when anticipated
Shortage-of-gas program in progress
Fault with Base Unit (LMV5)
Parameter of max. safety time faulty
Fault with timer1
Fault with timer2
Fault with timer3
No burner identification defined
No service password defined

Corrective action
1) Bubble test gas valve to ensure that the upstream
valve is not leaking. If leaking, replace.
2) Ensure that the setpoint of the PS(M)-VP is 50% of
the pressure upstream of V1 (upstream valve)
1) Bubble test gas valve to ensure that the downstream
valve is not leaking. If leaking replace.
2) Ensure that the setpoint of the PS(M)-VP is 50% of
the pressure upstream of V1 (upstream valve)
1) Configure oil train so that low oil pressure switch is off
when the oil pump is not running.
2) Check to ensure switch is wire Normally Open.
1) Ensure oil pressure exists at the switch when the oil
pump is running. Adjust pressure reg. if needed.
2) Check to ensure switch is wired Normally Open.
Check setpoint of switch.
1) Ensure excess oil pressure is not present at the
switch. Adjust pressure reg. if needed.
2) Check to ensure switch is wired Normally Closed.
Check setpoint of switch.
1) Check setpoint of switches.
2) Ensure switches are closing and opening at the
correct times (see sequence diagram)
1) If repition counter enabled (outside north america) the
LMV is wating for gas pressure to return.
If fault occurs continously, replace LMV5
