Comissioning
Check that the controller and sensor are connected properly. Do not supply power to the controller until
all wires or cables are connected properly for selected output.
The sensor probe and the control box are calibrated before shipment. The output should be checked before
and after mounting and is adjustable as described below.
Adjusting / trimming the output
A shorter electrical stroke is possible by adjusting on the controller, maximum 10-15 % on each end. Before
adjusting the output check that the jumper settings are in the right position for the desired output.
Output adjustment using the mid-position
This approach to adjusting the output require a way to move the piston to the center of its movement
(mid-position). I some cases that can be difficult, in that case use adjustment by end positions as described
below.
1. Move the piston rod to its mid-position (half of the desired stroke length).
2. Adjust on the screw ”BALANCE” until 50 % of the output is achieved, for example 12 mA on 4-20 mA
output.
3. Run the piston rod to the desired inner position. Adjust with the screw ”GAIN” until 0 % of the output (or
100 % if reversed).
4. Check that output at outer position is 100 % and repeat if necessary.
Output adjustment using the end positions
If the mid-position is impossible to find accurately the following procedure may be used instead. This way
of output adjustment requires some calculations and a calculator is recommended.
1. Move to inner position and adjust the BALANCE until the target value 0% of output is reached (or as
close to the target value as possible in case it can’t be reached).
2. Move to outer position and note the measured value. Adjust the BALANCE until the signal is half-way
to the target value. Example: target value is 20.00 mA in outer position and the measured value is
19.00 mA. Then adjust the BALANCE screw until the value is 19.5 mA.
3. Still at outer position, adjust the GAIN screw until the target value has been reached.
4. Move to inner position to check that the value still match the target value for that position. If further
adjustment is necessary repeat the steps above until the signal is correct.
