Multi-User Function
This function is for when the LI-2B gate operator is installed for multi-users (e.g. flats,
Apartments etc.) There is a Jumper installed on a three-pin block approximately in the
middle of the main control board. If the Jumper is on pins one and two the operator WILL
NOT allow the gate to close on a signal, it will continue to open position, time out then auto
close. If the Jumper is on pins two and three (Normal) a signal e.g. from the remote control
will reverse the direction of the operator.
Overloads
The overloads (See figure 9) are preset to maximum sensitivity, i.e. slight pressure will cause
the operator to STOP if it is opening or STOP & OPEN if it is closing.
Note: If these functions are reversed i.e. the gate STOPS when closing and STOPS and
REVERSES when opening then the polarity of the motor connections MUST be reversed and
the limit switch cams adjusted.
There is ONE overload for each gate as indicated on the main circuit board. To reduce the
sensitivity on the main circuit board turn the overload dials in the Anti-Clockwise direction.
BE CAREFUL
large reductions in sensitivity may allow the gate(s) to exert excessive
pressure on people or vehicles trapped in the path of the gate(s).
Anti-Clash Leaf Delay for Pairs of Gates
To avoid jamming there is a time delay between the movements of each gate. This delay
may be independently adjusted for the Opening sequence and the Closing sequence.
Dial “R24” changes the closing delay and “R27” changed the opening delay.
In situations where the master operator is on the right hand side looking out, the “R24” sets
the Opening delay and “R27” sets the Closing delay.
Turning the dials/trimpots Anti-Clockwise gives the minimum delay.
