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 .
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 DIP switches 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 blue LED D1 will turn on, and grn LED STA will turn on.
11. Press the “SET” black pushbutton on the Mod control board and hold it down for
about three seconds, then release.
A. The grn STA LED will turn off and the unit will drive to the full CCW (Open)
position and stop when the pre-set cam positions are reached. There are
Alignment of the sector and
potentiometer gear sets at
actuator full CW position.
(ref step 9).
NO LED indicators to advise
when the actuator is running.
12. When the actuator stops, press
the OP pushbutton ONCE.
A. The actuator will drive to its
full CW (Closed) position and
stop when the pre-set cam
postions are reached.
13. When the actuator stops, press
the CL pushbutton ONCE.
14. The unit will start to respond to the
incoming 4-20mA control signal
being sent to the actuator.
15. Slight adjustments may be made
to trimmer VR2 if necessary to
tune the feedback signal.
16. Unit is now calibrated and is ready
to be put into service. No other
calibration is necessary.
WARNING –
Follow these directions carefully and in order. Actuator damage due to improper testing
and commissioning will NOT be covered under warranty.
