Q
Q
In dual pump operation, pump cycling is done every 24 hours (config-
urable).
Pump cycling can be triggered:
• Internally, time-controlled (menu <5.1.3.2> + <5.1.3.3>)
• Externally (menu <5.1.3.2>) by a positive edge at the "AUX" contact
(See Fig. 21),
• or Manually, (menu <5.1.3.1>).
Manual or external pump cycling is possible 5 seconds after the last
pump cycling, at the earliest.
Activation of external pump cycling simultaneously deactivates
internal time-controlled pump cycling.
Actual value input IN1 setpoint input IN2
• 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/PDA) 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 IR-Monitor (or using the PDA)
as an individual fault signal (ESM) or collective fault signal (SSM)
(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.
