4.6 ZS400 startup
If the startup conditions are not fulfilled after switching on the power supply
module, the ZS400 switches to startup/stop, i.e. after switching to Run a
cold start is performed.
If a battery failure occurs in battery operation, or the ZS400 was unplugged,
no startup can take place; error message
. Startup is performed once
the battery failure is acknowledged and the PLC program is loaded.
Startup is then carried out independently of the setting of the retention
switch as a first start.
