Alarm acknowledgement
To cancel remote alarms although a
measured value is still in an alarm state,
alarms can be acknowledged in the
device.
To do so, press the acknowledgement
button located to the right of the red LED.
The alarm relay changes its switch status
back to the idle state. The
red error LED
flashes.
The alarm acknowledgement can be can-
celled by pressing the acknowledgement
button again.
One acknowledgement button is responsible for both measurement channels.
The remote alarm becomes active
• When the measured value has been within the permissible range in the
meantime and then again moves outside it
• When the measured values of the other measurement channel are outside
the permissible range
A fault message from the pipe connection monitoring system cannot be
acknowledged as it is so serious that it must be rectified immediately .
Deactivating measurement for service purposes
If the measurements are to be deactivated for service purposes, one of the
acknowledgement buttons must be pressed for at least 5 seconds. The two
green ISO “error” LEDs flash.
Test leads a and b are then bridged internally with 10 Ω . A loop or insulation
measurement can be performed from the end of the cable.
At the same time, a timer starts, which automatically reactivates the module
after 12 hours.
Pressing and holding the same acknowledgement button again for at least
5 seconds reactivates the measurement.
Note:
When the measurement channel is deactivated, the measurement input is
bridged with low-impedance so that the measurement loop can be measured
manually at any point with "normal measurement voltage" (max. 100 V DC /
70 V AC).
