THD-U / THD-I / TEMP 2 alarm = switch off active stages
Yes/No
“
NO
”: active stages are not switched off in case of an alarm.
“
YES
”: If the digital input alarm is triggered after running out of the delay
time of 10 s, all active stages (
“AUTO” & “FON”) are switched off one by one
referring to the switch-off interval set under SETUP/523 and are locked for
30 min. The last active stage is switched off first, when the switch-off interval
has run out after the signalling of the alarm. Then, the other stages are
switched off one by one referring to the switch-off interval. As all active
stages have been switched off, the control stops for as long as one out of
these three alarms is still active.
NOTE:
The control is stopped while the alarm is still active. The stages
which have been switched off by the alarm system are locked for max. 30
min. Active
“FON” stages are also switched off and blocked. Stages which
have been switched on manually are NOT switched off. If stages are
switched off manually, they are only locked until the discharge time is
expired.
NOTE:
The THD-U-, THD-I- or the Temp2-alarm can also lock the control
system and initiate the sequential deactivation of active stages.
