Setting Range in seconds
SSM reset delay 0 s to 60 s
Table 34: Trigger and reset delay
ƒ
Triggering of the SSM signal after occurrence of a fault or a warning is delayed.
ƒ
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 end of the set time, there will be no message to
SSM.
A set SSM trigger delay of 0 seconds immediately reports faults or warnings.
If an error message or warning message occurs only for a brief duration (e.g. in case of a
loose contact), the reset delay prevents the SSM signal from fluttering.
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 twin-head pump opera-
tion
ƒ
SSM The SSM function must preferably be connected to the main pump.
The SSM contact can be configured as follows: the contact reacts either only in the
event of a fault or in the event of a fault and a warning.
Factory setting: SSM only reacts in the event of a fault.
Alternatively or additionally, the SSM function can also be activated on the standby
pump. Both contacts work in parallel.
ƒ
ESM The ESM function of the twin-head pump can be configured on each twin-
head pump head as follows:
The ESM function on the SSM contact only signals faults of the respective pump
(individual fault signal). In order to detect all faults of the two pumps, the contacts
must be assigned in both drives.
13.2 Application and function of SBM
relay
The contact of the collective run signal (SBM, potential-free changeover contact) can
be connected to a building automation system. The SBM contact signals the operating
status of the pump.
ƒ
The SBM contact can be assigned to any of the two pumps. The following config-
uration is possible:
The contact is activated when the motor is in operation, power supply is present
(network-ready) or no fault is present (ready for operation).
Factory setting: ready for operation. Both contacts signal the operating status of
the twin-head pump in parallel (collective run signal).
Depending on the configuration, the contact is set to NO or NC.
In the “Settings” menu , select
1. “External interfaces”
2. “SBM relay function”.
Possible settings:
Selection option Function SSM relay
Motor in operation (factory set-
ting) SBM relay connects only when motor is running.
Closed relay: the pump is supplying.
Power supply ready SBM relay connects for power supply. Closed relay:
voltage available.
