Introduction
The user can change the SET button to any other convenient set point (see Settings). In
addition, the control knob is speed-sensitive; turning it faster produces a faster change in the
output.
The normal industrial process control loop current range, or span, is 4 mA to 20 mA (0% to
100%). Intermediate points are as follows:
Settings
The IPM-100 has two selectable settings: Automatic Power-off and the current/percent
set point of the SET button.
To change Automatic Power-off setting:
1. Press and hold the SET button while turning the unit on.
2. After the firmware revision appears on the display, release the SET button. BAT and
ON indicate that Automatic Power-off is enabled.
3. Press the MODE button to change the Automatic Power-off function (ON or OFF).
4. Press the SET button to store your selection.
To change current/percent set point for SET button:
1. Use the control knob to set the output to the desired value.
2. Press the SET button to store the selected value.

The Read Function measures current from
0.00 mA to 24.0 mA (–25% to 125%).
1. Open the loop at any convenient point.
2. Select READ and press the MODE button until
READ appears on the display.
3. Press the mA / % button to select current or
percent.

Operation (cont’d)
Power Transmitter
The Power Transmitter Function
relies on the internal battery to
power the circuit (12 volts DC
nominal at 24 mA) while simulta-
neously reading the current.
1. Disconnect one or both of the
input wires to the 2-wire
transmitter to be calibrated.
2. Select POWER TRANSMITTER
and press the MODE button until PWR XMTR appears on the display.
3. Press the mA / % button to select current or percent.
4. Connect the red lead to the positive (+) side of the circuit; connect the black lead to the
negative (–) side of the circuit.
5. Connect an appropriate sensor or calibrator to the input of the 2-wire transmitter.
6. Calibrate the transmitter in the usual manner.
Valve Setup
Proper valve setup requires setting the end stops. Select either SOURCE or 2-WIRE
SIMULATOR to control the valve. Refer to the corresponding illustration.
1. Disconnect the control loop’s 4 mA to 20 mA control wires from the current-to-pressure
(I/P) converter or actuator.
2. Connect the IPM-100 to the device.
3. Press the 0% / 4 mA button and adjust the fully closed stop on the actuator.
4. Slowly turn the control knob counterclockwise and verify that the actuator and valve do
not move. Repeat Steps 3 and 4 until the stop is set correctly.
5. Press the 0% / 4 mA button again and turn the control knob clockwise. The actuator and
valve should move.
6. Press the 100% / 20 mA button and adjust the fully open stop on the actuator.
7. Slowly turn the control knob clockwise and verify that the actuator and valve do not move.
Repeat Steps 6 and 7 until the stop is set correctly.
8. Press the 100% / 20 mA button again and turn the control knob counterclockwise. The
actuator and valve should move.
