Test functions for the analog interface
Set current
This function sets the current to any value between 0 and
22 mA. Analog offset and analog span are not used for this
function.
1. Select
Settings > Communication > Analog interface >
Set current
and confirm.
2. Once the alarms at the central controller are inhibited,
confirm the message

The setting for the current is displayed.
5. Select
Next
and confirm.
6. Select
Set current out
or
Current off
and confirm.
7. Select
Next
and confirm.
The function is terminated.
8. Once the alarms at the central controller are enabled
again, confirm the message
Enable all alarms
.
NOTICE
The
static
signal type is a constant current. However,
the current value can be configured.
The
dynamic
signal type is a square wave signal with
the following characteristics.
NOTICE
The maintenance current can only be set if the
maintenance signal has been set to static.

NOTICE
These functions change the current of the analog
interface for test purposes (e.g. to check the
programming of the central controller). It might be
necessary to inhibit the alarms at the central controller
to avoid false alarms. After exiting these functions, the
currents, if changed, will automatically return to the
maintenance signal.
During the test, the maintenance symbol [
] is
displayed.
