ZAdyn4B standby function
To save energy at standstill, the ZAdyn4B can be switched to stand-by mode. Internal components of
the ZAdyn4B are switched off in stand-by mode. This means that the ZAdyn4B has a much lower
power loss at standstill. There are two stand-by modes in the ZAdyn4B: Standby 1 and Standby 2
Standby 1:
In Standby 1 mode, the rotary encoder, monitoring functions and the output relay remain
active,
Standby 2:
In Standby 2 mode, the rotary encoder is switched off, the monitoring functions are not active
and all relays are switched off, including the fault indication relay.
