SSM reset delay
Table 30: Trigger and reset delay
▪ Triggering of the SSM signal after occurrence of a fault or a warning is delayed.
▪ Resetting of the SSM signal after occurrence of a fault or a warning is delayed.
Trigger delays are used so that processes are not influenced by very short fault or warn-
ing messages.
If a fault or a warning is fixed before the set time, there will not be any message to SSM.
A set SSM trigger delay of 0 seconds immediately reports fault or warnings.
If an error message or warning message occurs only for a brief duration (for example in
case of a loose contact), the reset delay prevents a flutter of the SSM signal.
NOTICE
SSM trigger and SSM reset delay is set to 5 seconds as a factory setting.
SSM/ESM (collective fault signal/individual fault signal) in double pump operation
▪ SSM: The SSM contact can be assigned to any of the two pumps. Factory setting: Both
contacts signal faults at the double pump in parallel (collective fault signal).
▪ ESM: The SSM function of the double pump can be configured so that the SSM contacts
only signal faults of the respective pump (individual fault signal). In order to record all
faults of the two pumps, both contacts must be assigned.
The contact of the collective run signal (SBM, potential-free normally open contact) can
be connected to a building automation system. The SBM contact signals the operating
status of the pump. The SBM relay can either switch on for "Motor in operation", "Ready
for operation" or for "Power supply ready".
▪ When the pump is running in the set operating mode and based on the next settings,
the contact between the terminals COM (85) and RUN (88) are closed.
In the "Settings" menu
1. "External interfaces"
2. "SBM relay function".
Possible settings:
Selection option
Motor in operation (factory set-
ting)
Power supply ready
Ready for operation
Table 31: Function SBM relay
After confirming one of the selection options, the SBM trigger delay and SBM reset
delay are entered.
