before, if necessary. After this, manually set the operating hour counter of
the controller under SETUP/603 back to 0 h. The alarm messages (display
and alarm relay) are not reset automatically until the switching cycle
counters of all steps 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 active.
NOTE:
The limit value can only be entered as full hours.
509
Max. operating hours of a step
1...65500 h
Limit value of the operating hours for the steps for the service alarm. If the
service alarm is activated (SETUP/506 = YES) and if the limit value of the
operating hours for the steps is exceeded by 1 h, the service alarm is
signalled immediately and the message “
OPH
ALARM
” is shown on the
display alternatingly with the step number. Only the lowest step number of
the affected steps is displayed. The alarm relay opens its contact.
In order to reset the alarm, perform preventive maintenance works at the
affected steps, if necessary. After this, manually set the operating hour
counters of the affected steps 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 steps 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…200%
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 steps ("AUTO" & "FON")
are switched off one by one with the delay time set under SETUP/504 and
are locked for 30 min. The last active step is switched off first, when the
delay time has run out after the signalling of the alarm. Then, the other
steps are switched off one by one at the interval of the delay time. When
all active steps have been switched off, the control is stopped for as long
as the alarm is still active.
If the value falls below the set THD-I limit value, a still active step switch-
off sequence is cancelled. The already switched-off steps, 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
steps 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 steps which
have been switched off by the alarm system are locked for max. 30 min.
Active “FON” steps are also switched off and blocked. Steps which have
been switched on manually are NOT switched off. If you manually switch
off a step, this is only locked during the discharge time.
