C. Parameter unit:
The Parameter unit plugs into the drive and permits changing values of pertinent
parameters
(see Figure 7.4 ).
7.3 Preliminary checks:
This procedure is to assure that the motor turns in the correct direction, and all speed signals are in
the working order.
A. Place the RUN/CAM SETUP switch in the RUN position and place the AUTO/MAN switch in the MAN.
Position.
B. With the door fully closed, hold the OPEN/CLOSE switch in the OPEN position while observing the
door movement. If the motor turns in the wrong direction, turn Power OFF, swap any two of the three
motor leads. The door should change speed as the various cams operate the speed controlling speed
sensors.
The door should start moving at low speed with the SSO sensor blocked and then accelerate to high
Speed (HSO) as the SSO sensor is unblocked. Deceleration takes place when the MSO sensor
is blocked, then more deceleration with the FSO sensor is blocked, and finally the DOL sensor
is blocked and the HOLDING LED turns on. A little power will apply to the motor to hold doors open.
When the door is fully open, hold the switch in the CLOSE position, the door should start accelerating
To high speed (HSC) and then decelerating as the FSC sensor is blocked. Finally the DCL sensor
is blocked and the HOLDING LED turns on. Again, a little power will apply to the motor to hold doors
open. (See 7.7 CAM SETTING VS. DISTANCE).
