ProAct P-Series FL Position Controller

Mode: 0–5 V (dc)
If the input is used for 0 V to 5 V, connect a voltage source between TB4 and
TB5, and set Jumpers JPR3 and JPR5 both to Position C.
Mode: 4–20 mA
If the input is used for (4 to 20) mA, connect a current source between TB4 and
TB5, and set Jumpers JPR3 and JPR5 both to Position B.
Mode: 0–200 mA
If the input is used for (0 to 200) mA, connect a current source between TB4 and
TB5. The signal at TB4 must be more positive then the signal at TB5. Set
Jumpers JPR3 and JPR5 both to Position A.
When jumpers are set for the (0 to 200) mA Analog Input Range,
shorting 24 V power (+) to TB4 (Analog Input +) could damage the
circuit.
Analog Input scaling and failure diagnostics are provided and are based on
software configuration. These settings can be modified using the Service Tool.
The default scaling for the Analog input ranges is:
Range
Min (0 %)
Max (100 %)
(0 to 5) V (dc)
0.5 V (dc)
4.5 V (dc)
(4 to 20) mA

An analog output provides an analog output signal representing the actual shaft
rotational position. The output is jumper selectable as either (4 to 20) mA or
(0.5 to 4.5) V (dc) representing (0 to 100) % position. Optionally it can be
configured to represent the position setpoint.
The (4 to 20) mA analog output drives a (0 to 450)
Ω
load. The high side (TB1)
drives current from the internal 15 V (dc) power supply to the load. Connect the
return current to TB2. TB2 is internally connected to the power supply ground.
The shield (TB3) connection is shared with the analog input.
