• At the master: acts on the whole unit
"External 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-Moni-
tor/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-Moni-
tor/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.
NOTE:
"Readiness" means:
"Operation" means:
"Mains on" means:
• The contact must be made to each pump for individual run signals.
The only settings that are possible at the slave are "External Off" and
"Disable/enable pump".
NOTE:
If an individual motor is switched voltage-free in a double pump, the
integrated dual pump management is deactivated.
When communication is interrupted between two pump heads in dual
pump operation, both displays show the error code "E052". Both
pumps behave as single pumps for as long as the interruption lasts.
• Both electronic modules report the malfunction via the ESM/SSM
contact.
• The slave pump runs in emergency operation (manual control) 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: n = 1850 1/min
• For 4-pole pumps: n = 925 1/min
The pump could run, there is no fault.
