Setting Cycle Timers & Auto Close Times

The control board has pre-set cycle times which are used to set the maximum time the controller will drive

the motors in the open and closed directions. The pre-programmed time for the open and close cycle

timer's is 60 seconds. The control board also has a pre-set pedestrian access time of 5 seconds which is

intended to open the motor connected to M1 output only part way. If these default times do not suit your

needs simply use the procedure below to adjust them. Note the same procedure can be used to adjust the

auto-close times.

Place the slide switch into the "set" position

Adjust the timer's value by pressing and holding the required push button for the desired time.

Repeat step 2 for the next timer (if desired).

Place the slide switch back into the "RUN" position.

Test operation.

Make sure that the slide switch is placed back into the "RUN" position before testing the new timer value.

As you can see the procedure used to set each timer's value is the same only the push button used changes.

Each push button is clearly labelled underneath as to which timer's value it sets. Note when setting the

OPEN, CLOSE and PEDESTRIAN cycle times the controller will drive the motors as if a "real" cycle is

being executed. The difference being that the motors will stop as soon as the button is released or the limit

switches are reached. The OPN status LED on the control board will flash at 1 second intervals to assist

setting times. Note when setting the OPEN and CLOSE cycle times when limit switches are used, release

the push button a few seconds after the limit switch cuts motor power. This allows for the motors to slow

down over the life of the operators without the need to adjust again.

Variable Speed Drive Unit

The variable speed drive unit will, ramp up the speed of the operator and then ramp down prior to

closing.

It must be remembered that the limit switches are to be set in a position which initiates the ramp down

time. Therefore, the limit switches need to operate much sooner than when there is no variable speed

drive unit.

The accelerate and decelerate times have been set in the factory for the normal installation but can be

changed if necessary. Similarly, the speed that the gate operates at has also been set but can be

changed (up to approx 70Hz).

NOTE changing the speed will change the position the gate will end up in its fully closed and open

position. (Unless limit switch cams are also adjusted accordingly).

Accelerate time (FN01)

Decelerate time (FN02)

Closing Speed (FN08)

Running Frequency

To change accelerate time: Press DSP/FUN button

Use arrows to select FN01

Press DATA/ENT

Use arrows to select new time

Press DATA/ENT

Press DSP/FUN

To change decelerate time: as above except select FN02

To change closing speed: as above except select FN08. If opening speed and closing speed is to be the

same, remove wire link between REV and SP1 terminals on invertor.

To change opening speed of operator: when display is flashing and showing Hz, use arrows to raise or

lower the Hz figure.

NOTE frequency upper limit has been set to 70Hz and lower limit 30Hz.
