Alarm (fault message output)

The "Alarm" output is a volt-free change-over relay contact. During
trouble-free operation, the contact between the terminals 15 – 16 is
closed and the one between terminals 14 – 16 is open. In case of a
voltage breakdown, the contact between the terminals 14 – 16 is
closed and the one between terminals 15 – 16 is open.
The instrument is equipped with a range of monitoring functions. You
can define the individual statuses as a fault and program the
corresponding message either as a continuous contact (A) or as a
message impulse (M).
Functions/Behaviour of the "Alarm" output:
- With a continuous contact, the "Alarm" output remains activated
(terminals 14 – 16 closed) as long as the fault persists.
- With a message impulse, the output is switched 'on' for 2
seconds and then switched 'off' for 5 seconds.
- If several faults with differently programmed messages are
signalled simultaneously, the output is switched to continuous
contact.
- The red LED "Alarm" and the text on the display indicate a fault.
- The fault message signal at the "Alarm" output is deleted by
confirming the fault via the "Horn" key.
- The error message can only be deleted if the fault has been
eliminated.
- Exception: The maintenance date has been exceeded. This
message is confirmed in the M menu, see below (Maintenance).
- Each new fault is entered into the error history (also see "i
menu").
- There is no additional alarm via the fault message output when
the limit value is exceeded!
The error messages are described under "Error messages/
Troubleshooting"

Maintenance (output for maintenance message)

The "Maintenance" output is a volt-free change-over contact. During
trouble-free operation without a programmed maintenance interval,
the contact between the terminals 17 – 19 is closed and the one
between terminals 18 – 19 is open.
The instrument is equipped with a range of monitoring functions and
a programmable maintenance interval. The respective maintenance
message is always a continuous contact.
A maintenance request is displayed via the yellow "Maintenance"
LED. The maintenance display can only be deleted once the status
has been corrected or after the maintenance request has been
confirmed.
Please refer to the section "Password protection and basic
programming" for further programming details.
