Main/standby mode "
Only the master pump runs. In the event of a fault or a power failure
of the master, the slave starts at 50 Hz fixed speed. The fixed speed
can be changed if required by Salmson after-sales service.
The slave pump performs a pump kick every 24 hours. This period is
adjustable (see Section 8.3 "Setting the time relay" on page 46). No
pump cycling takes place.
The module is wired according to the terminal diagram (Fig. 8).
Parallel operation "
In parallel operation, both pumps always run synchronously.
In the event of a pump head fault, the other pump head continues to
run. After rectifying the fault, the pump head that is in operation
stops briefly before both heads immediately restart synchronously.
The module must be wired according to the terminal diagram (Fig. 9).
The electronic module has the following inputs/outputs:
• +24 V (output):
DC voltage for an ext. consumer/sensor. The output can be loaded
with max. 60 mA. The voltage is short-circuit proof.
• 0...10 V (input):
During pressure controlled operation, the actual pressure value must
be applied by the differential pressure sensor as voltage signal from
0 V to 10 V.
• 0...10 V/0...20 mA (input):
In manual control mode, the speed can be set via an external current
or voltage signal. The frequency and thus the speed follow the signal
(in accordance with Fig. 11).
During pressure controlled operation, the pressure setpoint can be set
via an external current/voltage signal. Then, the differential pressure
follows the signal (in accordance with Fig. 10).
• GND (signal earth):
Earth connections for signal inputs (0...10 V or 0...20 mA).
• Ext. off (release):
The pump can be switched on/off via an external potential-free con-
tact. In systems with a high switching frequency (> 20 switching on
and off operations per day), switching on/off is to be done via
"Ext. off".
• SBM (collective run signal):
For a central control station, a collective run signal can be connected
via the potential-free contact. The run signal changes when the
motor is at a complete standstill.
• SSM (collective fault signal)
For a central control station, a collective fault signal can be connected
via the potential-free contact.
The pumps are equipped with an electronic overload protection
function which switches off the pump in the event of an overload.
For data storage, the modules are equipped with a non-fading mem-
ory. The data is retained no matter how long the module is discon-
nected from the power supply. When the power supply is re-estab-
lished, the pump continues to run with the values set prior to discon-
nection from the power supply.
