5.16.4 SYSTEM BEHAVIOR – LOST COMMUNICATIONS
BMS lost communications with:
PF3102-00 Ion Pilot card(s) or
PF3102-01 UV Pilot card(s)
When Minimum Pilots Running setting is
satisfied
PF3102-00 Ion Pilot card(s) or
PF3102-01 UV Pilot card(s)
When Minimum Pilots Running setting is not
satisfied
PF3103-00 Temperature card
See note 2 for behavior with redundant inputs
PF3113-00 IO Expansion card with Main
Permissive input
See note 2 for behavior with redundant inputs
PF3113-00 with Wait input
See note 2 for behavior with redundant inputs
PF3113-00 with Alarm input
See note 2 for behavior with redundant inputs
PF3113-00 with Warning input

PF3113-00 with Display input
1 When Pilot Off mode is set to Off After Main On, the controller transitions to the Waiting state, then purges the system before
reigniting and proceeding to Pilot.
2 The system acts on a communication loss event only when all redundant inputs lose communication with the BMS controller
(e.g., A running system with three thermocouple devices measuring a single temperature input continues to run if one or two
of the thermocouple inputs lose communication with the BMS controller).
