Zap JACKSHAFT MOTOR-CONTROL SYSTEM 815-RL - Manual (Page 17)

DOOR DIRECTION ASSESMENT
The motor direction will depend on which side of
the shaft the Operator is mounted.
In order to assess the correct direction of
movement of the door first release the Manual
Over-Ride Lever and move the door manually to a
half open position. Then re-engage the Manual
Over-Ride Lever. Momentarily press the Control
unit case lid button. The door should initially run
in the OPEN direction and is confirmed by the
illumination of the OPENING LED at the top right
hand side of the control panel (pic 34). Now press
the case button to stop the motor. Then isolate
the main A/C power supply.
If the door runs in the closed direction, isolate the
main A/C power supply and set SW7, the Motor
Polarity switch to the opposite position.
DO NOT
MOVE THE SWITCH WHILST THE MOTOR IS
RUNNING.
DOOR SPEED CHANGE POINT
CALIBRATION
Release the Manual Over-Ride Lever and move the
door manually to the fully closed position, re-
engage the lever and re-connect the mains power
supply. The microprocessor reference for the door
ground position should now be set. The procedure
is referred to as a
CALIBRATION RESET . This is
completed as follows:
1. Press and hold the Reset button. (see pic 32
and 33).
2. Press and hold the Program button.
3. Release the Reset button.
4. Wait until the Acknowledge LED flashes (and
beeper sounds).
5. Then release the Program button.
6. The Acknowledge LED will flash twice (and the
Beeper will sound two beeps) to confirm.
Now momentarily press the control unit push
button. Note that the opening LED is illuminated
whilst the door is opening. (pic 34)
The door will run in fast speed for a few seconds
then change to slow speed and stop when it
compresses the buffer springs, if fitted, or reaches
the fully open position when the counterbalance
cables are pulled tight.
The microprocessor now knows the door opening
height and will calibrate the speed change points
after the next few runs, until they are set a few
seconds from each limit of door travel.
Now momentarily press the case push button to
run the door in the close direction.
Note that the CLOSING LED, LD4, is illuminated
whilst the door is closing. (Pic 35 overleaf)
