PF3100 TROUBLESHOOTING – SOLUTIONS TO COMMON PROBLEMS
Proof of closure contact failed to open
The BMS has a proof of closure contact enabled in the settings and it is closed when it should be open.
Solution:
Check that the POC valves are wired correctly and that the solenoid wiring is also correct. The valve may not be
opening or the POC signal may not be correct back to the BMS.
ESD or start contact open
The ESD or Start contact on the BMS is open. Both need to be closed before the system will be allowed to start.
Solution:
Check that the ESD or Start wiring is correct. The signals are closed when power is applied to the negative
contact (signal input) from the positive contact.
Thermocouple error or no valid process/aux temperature
It is likely that a thermocouple is open or not connected.
It the temperature module is completely disconnect this alarm along with an IO Communication error will show
up.
Solution:
Determine if the temperature module is still communicating by opening the Swap wizard or Temperature wizard.
If the module is not communicating, follow the troubleshooting instructions for communication errors. If the
module is communicating, check the thermocouple wiring.
Solenoid LSS error
This can show up for any of the valves. It means that the low side of the valve has been connected to ground
when it shouldn't be.
Solution:
Check if the low side valve is grounded with a multi-meter. If it is re-wire the valve so that it connects directly to
the BMS valve – and not to ground.
