Safe Shut Down of Control Unit (H8/S7)
It's not recommended
to do a safe shutdown of FT128 before power down the FDCIE
which means disconnecting it from 230 V AC and battery. Safe shut down will save the
SSW in a Flash memory and also put the CPU at rest. See also chapter" Restart ", page
82.
It's recommended
to do a safe shut down after commissioning the installation and after
calibration of supervised outputs, change of access code etc.
Note: By restart and power down, the Fault TX relay, which is energised in quiescent /
normal state, will de-energise, i.e. the relay contacts will alternate.
The code for the two restart faults will be 00 after Power off / Power on restart and 03 after
a countdown restart.
Note: Before the very first safe shutdown, the Flash ROM is empty. Then every time safe
shut down is performed, the valid data will be saved in the flash ROM, i.e. any old data will
be overwritten. When the FT128 is powered up, the data stored in the Flash ROM will be
used.
WARNING! If safe shut down is not performed just before you power off a control unit, then
by power on, the Flash ROM might be empty which means the default settings will be
used. Or the stored data might be old and not valid.
