The
alarm module
can in addition to the
above power module, provide 3 customer
individually settable alarms and 2 inputs. The
module is supplied with a 2 meter fly-lead
cable.
Each of the 3 alarm contacts can be
configured as high, low, window and totalizer
alarm. Once the alarm becomes active, the 3
potential free alarm contacts can be reset in
many different ways. Automatic, through the
touch screen or with one of the 2 input
signals. Other options like hysteresis settings
and delays are also available.
For detailed information see
4.11.2 Alarm
Menu
in this manual.
Both the power and the alarm module are
mounted similar to the battery module (see
3.16 How to replace the battery
). They
replace the battery module, so you cannot
use these modules in combination with
battery power.
