Manual or external pump cycling is possible five seconds after the last
pump cycling, at the earliest.
Activation of external pump cycling simultaneously deactivates
internal time-controlled pump cycling.
Pump cycling can be described schematically as follows (see also Fig. 21):
reaches the setpoint (grey line)
NOTE:
In manual control mode, a slight increase in flow can be expected.
Pump cycling is depending on the ramp time and generally lasts 2 s. In
auto control, there may be minor fluctuations in the delivery head.
However, pump 1 adjusts itself to the changed conditions. Pump
cycling is dependent on the ramp time and generally lasts 4 s.

nal (SSM) (menu <5.1.6.0>).
SBM can be set at <5.7.6.0> on the master.
NOTE:
"Readiness" means: The pump could run, there is no fault.
"Operation" means: Motor turning.
"Mains on" means: Mains voltage is present.
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.
