Actual value input In1,
Setpoint input In2: (The input behaves as shown in Fi g. 5 ):
• At the master: acts on the whole unit.
"Extern off":
• Set at the master (menu <5.1.7.0>): depending on the setting in menu
<5.1.7.0>, acts only on the master or on the master and the slave.
• Set at the slave: acts only on the slave.
ESM/SSM:
• A collective fault signal (SSM) can be connected to the master for a
central control centre.
• In this case, the contact may only be made to the master.
• The display is for the whole unit.
• This signal can be programmed on the master (or using the
IR-Monitor/IR-Stick) as an individual fault signal (ESM) or a collective
fault signal (SSM) in menu <5.1.5.0>.
• The contact must be made to each pump for individual fault signals.
EBM/SBM:
• A collective run signal (SBM) can be connected to the master for a
central control centre.
• In this case, the contact may only be made to the master.
• The display is for the whole unit.
• This signal can be programmed on the master (or using the
IR-Monitor/IR-Stick) as an individual run signal (EBM) or collective
run signal (SBM) (menu <5.1.6.0>).
• The functions - "Readiness", "Operation", "Mains on" - from EBM/
SBM can be set at <5.7.6.0> on the master.
NOTICE:
"Readiness" means:
"Operation" means:
"Mains on" means:
NOTICE:
If EBM/SBM is set to "Operation", EBM/SBM is activated for a few sec-
onds when pump kick is executed.
• The contact must be made to each pump for individual run signals.
The only settings that are possible at the slave are "Extern off" and
"Disable/enable pump".
NOTICE:
If an individual motor is switched to a voltage-free state in a twin-
head pump, the integrated dual pump management is deactivated.
When communication is interrupted between two pump heads in
twin-head pump operation, both displays show the error code
"E052". Both pumps behave as single pumps for as long as the inter-
ruption lasts.
• Both electronic modules report the malfunction via the ESM/SSM
contact.
• The slave pump runs in emergency operation (constant speed) mode
according to the emergency operation speed previously set on the
master (see menu items <5.6.2.0>). The factory setting for the emer-
gency operation speed is about 60 % of the pump's maximum speed.
• For 2-pole pumps:
• For 4-pole pumps:
The pump could run, there is no fault.
