Safe Shut Down of Control Unit (H8/S5)
It's not recommended to power down a Control Unit (i.e. no 230 V
without first performing a safe shut down of the Control Unit. Safe shut down will save the
SSW in a Flash ROM and put the CPUs at rest.
If no safe shutdown is performed, it may also generate a fault when you power up the
control unit again:
FAULT: Read/write site data (SSW), control unit xx"
It's highly recommended to perform a safe shut down after commissioning the installation
and calibrating the supervised outputs, changing passwords etc. in order to save the new
valid values and codes.
Safe shut down can be performed from any Control Unit and any Control Unit can be
selected. A Control Unit without a front has to be shut down from another Control Unit.
Note: By restart and power down, the Fault TX output(s) will be "activated".
