Make all connections to the
MAIN terminal block ONLY!
The end stop travel (cams) of this actuator have been factory set and tested to respond between 0° and 90°
degrees rotation . If NO changes to end stops are required, this unit is ready to be put into service immediately
using this procedure . IF changes to the cam positions are required, refer to pages 8 ~ 10 before proceeding .
WARNING –
Follow these directions carefully and in order. Actuator damage due to improper testing
and commissioning will NOT be covered under warranty.
Calibration Procedure - Proportional Control
After completing all mounting and wiring procedures and main power is available, it is
now possible to commission the actuator.
1. Before applying power or making any wiring connections:
2. Set the geartrain in the full CW position.
3. Set the #1 and #3 cams according to the on/off procedure.
4. Set the unit in the full CCW position.
5. Set the #2 and #4 cams according to the on/off procedure.
6.
Set the geartrain back to the fully closed (CW) position.
7. Make your fi eld wiring connections for power, control and feedback signals, referring
to the correct wiring diagrams for your product.
A. Connections are made ONLY TO THE MAIN TERMINAL BLOCK.
B. No connections are made to the proportional control board directly.
8. Set the jumper headers for correct signal IN and OUT. (ref next page)
9. Rotate the potentiometer pinion gear to its full CCW position, then back about 1.5~2
teeth CW before tightening the two M3 setscrews on the sector drive gear.
10. Apply correct power according to the actuator model.
A. The red PWR LED will turn on.
Alignment of the sector and
potentiometer gear sets at
actuator full CW position.
(ref step 9).
11. Press the “Calibrate” black
pushbutton on the Mod control
board and hold it down for about
three seconds, then release.
A. The unit will run to its full
CCW position, stop for a few
seconds, then run back to its
full CW position.
12. After a few seconds, the unit will
complete the calibration routine
and will return to active operation
mode by responding to the
incoming 4-20mA control signals
being sent to the actuator.
13. Slight adjustments may be made
to the 4mA and 20mA trimmers to
affect accuracy on the feedback
signal as a function of actuator
position.
14. Unit is now calibrated and is ready
to be put into service. No other
calibration is necessary.
