STEP 5 - CONNECTING THE WINCH
Follow the wiring diagram to make the connections. The curtain should
open when the controller is in manual open and should close when the
controller is in manual close. If the curtain moves in the wrong direction,
switch the wires connected to the OPEN and CLOSE terminals.
STEP 6 - CHECKING CURTAIN LIMITS
To check curtain limits, close the curtain all the way by turning to the
MANUAL position on the controller and pressing the push-button twice.
Adjust the limit switch at this position to stop the winch from closing any
further. Open the curtain all the way by turning to the MANUAL position on
the controller and pressing the push-button once. Adjust the limit switch at
this position to stop the winch from opening any further.
STEP 7 - CONNECTING THE POTENTIOMÈTER
Follow the wiring diagram to make the connections. Make sure the variable
output on the potentiometer is connected to terminal #3 on the probe termi-
nals. The two power supply wires can be reversed. Check the potentiom-
eter by opening and closing the curtain all the way in the MANUAL position.
If the signal from the potentiometer (0 to 2.5 VDC) does not vary when the
controller sends a signal to the winch, the "Defective Potentiometer" pilot
light turns on.
NOTE: The potentiometer signal may not follow the winch signal. If this
happens, do not reverse the power supply wires on the potentiometer. The
calibration will correct this problem.
USE A SHIELDED WIRE FOR THE POTENTIOMETER AND DO NOT
!
GROUND THE SHIELD. ISOLATE THE POTENTIOMETER WIRE
FROM ALL HIGH VOLTAGE CABLES. DO NOT RUN THE WIRE
ALONG POWER CABLES.
