Left hand motor: rotate the bottom cam anticlockwise until it actuates the switch.
Right hand motor: rotate the top cam clockwise until it actuates the switch.
Re-tighten the limit cam cap-screw.
Open the gates
Operate the motors until their output shafts are in the correct position to engage with their
primary arms. Loosen the limit cam cap-screw.

Board adjustments
Sensitivity
Allow for the effect of weather. Wind or water will make the gates more difficult to move. If
the sensitivity is set to react to extremely light obstructions then the gates may fail to open
or close fully. After adjustment, check that the force on an obstruction at the far end of the
gate leaf does not exceed 150N (15 kg). Use a spring balance.
Travel time
Set the timer to allow 3 – 5 seconds more than the normal travel time. This compensates
for any possible slow-down due to unusual loads and will allow the gates to fully open or
close.
The yellow LED will stay on while the timer is active.
Auto-close
The jumper must be moved to the AUTO CLOSE position.
Turn the timer control clockwise to increase the delay, from a minimum of 6 seconds up to
a maximum of around 210 seconds.
Consider the use of the multi-user option (see below).
NOTE Non-contact sensor beams must be fitted when using auto-close.
Multi-user option
Move the jumper to the MU position. In this position every command will open the gate. The
only way to close the gate is to wait for the auto-close timer. The advantage of this mode is
that an opening gate with a car travelling through it can not be caught by someone pressing
a remote control to close the gate.
NOTE Autoclose must also be enabled, otherwise the gates can not be closed.
Motor 1 open delay
Essential when using gate tabs or overlapping leaves. To prevent clashing of the gate leaves
when opening, increase the Motor 1 open delay by turning the adjuster clockwise.
Motor 2 close delay
Essential when using gate tabs or overlapping leaves. To prevent clashing of the gate leaves
when closing, increase the Motor 2 close delay by turning the adjuster clockwise.
