222-224 RIP
4 – 20 mA
Transmitter 4 – 20 mA
The converter is delivered as a separate mounting block for MOA OC and MOA actuators with resistive transmitter
position. It transforms the signal of the 100
Ω
resistive transmitter to a unified signal of 4 – 20 mA. The supplied converters
are made by Treston, in the 222-224 RIPa/SO/BT III/ZOV design. They have an extended range of adjustability, even only
30% of the travel of the resistive transmitter can be converted to the output signal of 4 – 20 mA.
The Annex includes technical data and instructions of the converter manufacturer, which must be observed during assembly.
Setting procedure
– Set the actuator limit switches and the resistive transmitter according to the Assembly Instructions.
– Connect the converter according to the manufacturer's recommendations and remove the cap that covers the two
adjustment potentiometers.
– Set the range of the converter:
– adjust the actuator to the closed position and set the 4 mA current using the top potentiometer
– adjust the actuator to the open position and set the 20 mA current using the bottom potentiometer
– adjust the actuator to the closed and check the 4 mA current setting
– adjust the actuator to the open and check the 20 mA current setting
– if the values are set, cover the converter with the cap.
