PWM Adaptive Soft Start / Stop Speed Control Adjustment
The control board is equipped with adaptive adjustable PWM soft start / stop speed control.
The factory preset speed is set at a value of 4. Depending on the installation a different speed setting
might be needed.
IMPORTANT:
SW2 switch 4 is not a speed value switch. This switch must be set depending on
the linear actuator being used. OFF is the HD linear actuator (default) and ON is the PRO80 linear
actuator.
SW2 dip switches 1 - 3 control the soft start / stop speed.
The speed may be adjusted from a setting of 0 -7. Each of the 3 switches represent a binary value
and the switches turned ON add together for a speed setting.
switch 1 - value = 1
switch 2 - value = 2 switch 3 - value = 4
Looking at the picture you see the default speed value is set at 4 (SW2 switch
3 is ON)
If all 3 switches were turned OFF the value would = 0 (max speed)
If switch 1 and 3 were turned ON the value would = 5
If switch 2 and 3 were turned ON the value would = 6
If switch 1, 2, 3 were turned ON the value would = 7 (slowest speed)
The higher the value the slower the speed.
Avoid setting the speed value to a very slow speed, which would cause the motor to stall.
After speed value is changed cycle the gate multiple cycles to allow the adaptive speed control to
adjust to the new setting. The adaptive circuit will adjust the soft start / stop speed gradually to ensure
proper gate operation based on the speed value selected.
