Alarm and warning relay outputs
16. Alarm and warning relay outputs.
During service and regeneration various signals are available which can be used to trigger either the
alarm or warning relays. A comprehensive description of these signals is given earlier under the heading
Alarms/warnings.
At step 5, at step 10 and at step 18 the relay outputs can also be sent signals. If a relay output is sent
more than one signal, the relay operates as a joint fault / joint report.
If output relays are already occupied because of program choices made in section 5, 10 or 18 of the
programming the relay will function as a collective alarm or warning relay.
Capacity exceeded.
Displays 16.1 - 16.4 only
occur with 2-filter systems
In step 16.2, the user has to
decide, whether the outlet
valve of the duty column is
to be closed as soon as the
message "Cap. exceeded"
appears, or is to remain
open.
Power supply failure.
If power supply failure is a
regular occurrence,
operation of the alarm or
warning relay may be
undesirable. If steps 16.5,
16.6 and 16.7 are answered
YES, NO and NO
respectively then only the
supply failure message is
shown. This should be reset
at the earliest opportunity by
pressing the "UNLOCK" key.
