(See Fig. 27)
• Manually, (menu <5.1.3.1>)
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. 16):
reaches the setpoint (grey line)
NOTICE:
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.

(SBM) (menu <5.1.6.0>).
SBM can be set at <5.7.6.0> on the master.
NOTICE:
"Readiness" means: The pump could run, there is no fault.
"Operation" means: Motor turning.
"Mains on" means: Mains voltage is present.
NOTICE:
If EBM/SBM is set to "Operation", EBM/SBM is activated for a few sec-
onds when pump kick is executed.
