iVQ-E to R Range Adjustment and Calibration Manual
1. Modulating Control and Position Feedback Option Supplied:
This manual provides necessary information for calibrating the modulating control board and making any
fine tune adjustments to iVQ-E to R Range actuators. Each unit is shipped with initial calibration and factory
settings complete for a 0° to 90° operation.
If changes were made to the OPEN/CLOSE (CCW/CW travel) limit switches or new settings wish to be made,
the following steps must be followed for proper calibration of the unit:
1. Confirm actuator setup via the “DIP Switch Setting Chart”.
2. Confirm actuator performance via the “Deadband Setting Dial”.
3. Reset the potentiometer via “Potentiometer (VR) Adjustment”.
4. Reset the OPEN and CLOSE positions via “OPEN/CLOSE Calibration Procedure”.
5. Also refer to the “Troubleshooting Chart” at the end of this manual for additional help.

DIP Switch Setting Chart (Factory Setting is shown in RED)
Switches 1 and 2 correspond to the input signal setting, switches 3, 4, and 5 correspond to the output
signal setting, and switches 6, 7, and 8 correspond to the actuator command settings. If any changes are
made, turn OFF power and restart to activate the changes.

Deadband Setting Dial
The dial rotates clockwise from 1 through 0, 1 being the highest sensitivity rating and 0 being the lowest. As
you increase the sensitivity, you are increasing the amount that the actuator reacts to an input signal change.
The factory setting is typically set to 3.
Potentiometer (VR) Adjustment
The main potentiometer (also referred to as VR or
main Variable Resistor) is factory set to operate 90°.
If adjustment is required, it should be adjusted once
the OPEN/CLOSE limits are set, then move the
actuator to the fully closed position.
•For ALL Units – Loosen the set screw on the
sector gear and rotate fully clockwise. Re-tighten
the set screw.

OPEN/CLOSE Calibration Procedure
If travel cams were modified from factory settings, a re-calibration procedure must be followed to ensure
that the actuator will work correctly. (In the following procedure, it is assumed that the actuator is in the
fully closed CW position and the DIP switches are set to the factory setting as noted above).
Refer to the Modulating Control Board Layout above for component locations:
•Use the Pushbuttons on the Modulating Control Board to set the Open and Close position.
•Refer to the chart below for the description of each LED.

•Press the “SET” button for 2 seconds until LD9 is lit, then release. This is the Setting mode.
•CCW Setting:
oPress and hold the “UP” button until the actuator moves to the fully CCW position.
oLD2 is lit. Check to see if the output signal is equal to the 20mA signal.
oIf not, adjust VR2 until you achieve a 20mA output signal.
oPress the “MODE” button for 2 seconds. CCW setting is now complete.
•CW Setting:
oPress and hold the “DN” button until the actuator moves to the fully CW position.
oLD1 is lit. Check to see if the output signal is equal to the 4mA signal.
oIf not, adjust VR2 until you achieve a 4mA output signal.
oPress the “MODE” button for 2 seconds. CW setting is now complete.
•Press the “SET” button to exit the Setting mode.

LED3
It's not lit
Check power supply and verify wiring.
Board may be damaged. Send back to factory
for inspection.
LED4
Flashing or lit
(Applies to 24V models only)
Confirm that the voltage is within nominal
operating range (20.4-26.4V DC).
LED5
Flashing or lit
Confirm that the input signal is the same as dip
switch setting. Refer to "Dip Switch Setting"
section in this manual.
Check that setting is correct; might be set to 2-
10V input, but supply is 4-20mA.
The setting is set to 2-10V, but the input signal
is over 13.5V.
LED6
Flashing or lit means Motor
thermostat turns OFF
Frequency is too high for rated duty cycle.
Motor thermostat is not connected.
LED7
Flashing: Output signal short
circuit
Check wiring on terminals #11 and #12, should
be: #11 "-" and #12 "+".
Lit: The 2-10V input signal is
not connected properly
Check wiring on terminals #6 and #7, should be:
#6 "-" and #7 "+".
LED8
Flashing or lit means that
motor current is excessive
Frequency is too high for rated duty cycle.
Check the load.
The motor rotor is jammed.
LED9
Flashing or lit means that it is
in setting mode
Press "SET" once to exit the settings menu.

2) To enter the setting mode, press and hold ‘PB1’ and ‘PB2’ simultaneously, ‘LED CCW OPEN’ and ‘LED CW
CLOSE’ will begin to flicker.
3) Operate the actuator to the fully CCW OPEN position and press ‘PB2’, ‘LED CCW OPEN’ will flicker rapidly
for about 2 seconds. The fully CCW OPEN position is now set.
4) Check output signal at terminals 8 & 9 or terminals 8 & 10 depending on the DIP Switch setting selected.
5) Operate the actuator to the fully CW CLOSE position and press ‘PB1’, ‘LED CW CLOSE’ will flicker rapidly
for about 2 seconds. The fully CW CLOSE position is now set.
6) Check output signal at terminals 8 & 9 or terminals 8 & 10 depending on the DIP Switch setting selected.
7) Press and hold ‘PB1’ and ‘PB2’ simultaneously to exit the setting mode.

Troubleshooting Chart
Problem
Remedies
Modulating controller is not functioning.
Faulty main potentiometer (VR). Replace VR.
Remove the input signal wires. Operate actuator to
the fully closed position and readjust the VR. Refer to
"Potentiometer (VR) Adjustment”section of this
manual.
May be a wrong input signal. Review "DIP Switch
Setting Chart" section in this manual.
Faulty modulating board. Must be sent back to factory
for inspection.
The actuator is running open and close, but it is
not modulating.
The signal is reversed or there is a signal failure.
Improper wiring. Check that terminal #8 is hooked up
to "-" and terminal #9 is hooked up to "+".
The indication lights are flashing after the
operating check has been completed.
There is an incorrect setting. Review the "Open/Close
Calibration Procedure" to determine the problem.
