Set point adjustment
Set the switch SP1 (high value) or SP 2 (low value) to the ON
position, and adjust the potentiometer until due limit value is
displayed. Remember that only one switch can be in the
position ON. The limit relays have a fixed differential value of
approx. 5 %. SP1 (high limit) is activated on the limit value and
deactivates below the set limit value. SP2 (low limit) is also
activated on the set limit value but is deactivated above the set
limit value.
Adjustment of relay function (NO/NC)
and signal range 0/4 - 20mA
Limit relay function is set to NO (normally open) or NC (normally
closed) by 2 switches that are accessible when the back panel
is removed. Relays are factory set to NO (the relay switch
closes when the limit is exceeded).
A third switch change between 0 - 20 mA and 4 - 20 mA signal.
The instrument is factory set to 4 - 20 mA.
