NOTE: The limit value can only be entered as full hours.
509 Max. operating hours of a stage 1...65500 h
Limit value of the operating hours for the stages for the service alarm. If the
service alarm is activated (SETUP/506 = YES) and if the limit value of the
operating hours for the stages is exceeded by 1 h, the service alarm is
signalled immediately and the message
“
OPH
ALARM
” is shown on the
display alternatingly with the stage number. Only the lowest stage number
of the affected stages is displayed. The alarm relay opens its contact.
In order to reset the alarm, perform preventive maintenance works at the
affected stages, if necessary. After this, manually set the operating hour
counters of the affected stages under SETUP/405 back to 0 h. The alarm
messages (display and alarm relay) are not reset automatically until the
operating hour counters of all stages have fallen below the set limit and the
function
“Manual reset” (SETUP/501 = NO) is deactivated. The alarm relay
is only reset, if no other alarm is still active.
NOTE: The limit value can only be entered as full hours.
510 THD-I limit value
1…100%
Setting of the limit value for the THD-I monitoring. If the set THD-I limit value
is exceeded, the alarm is signalled (display and alarm relay) after the set
delay time (SETUP/ 504) and the message
“
HAr I
ALARM
” appears on the
display. The alarm relay opens its contact.
If the function SETUP/503 is activated, 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 the alarm is still active.
If the value falls below the set THD-I limit value, a still active stage switch-
off sequence is cancelled. The already switched-off stages, however,
remain locked until the blocking time (max. 30 min) has run out. If the control
has been stopped, this is restarted and the controller can switch the stages
again. If the function
“Manual reset” (SETUP/501 = NO) is deactivated, the
alarm messages (display and alarm relay) are reset automatically after 15
s. The alarm relay is only reset, if no other alarm is active.
NOTE: The control is stopped while the alarm is 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.
