ACTIVITY LED
Steady indication when gate is at
either open or close limit.
1 flash per second when gate is off
a limit in normal operation
2 flashes per second when
entrapment level one has occurred.
AUDIBLE WARNING DEVICE
If the operator should have a second
inherent obstruction in sequence with the
first; i.e. back to back, the sounder will
activate. Also the sounder can be
programmed to come on 2 seconds prior to
gate movement and stay on during gate
movement.

THREE BUTTON CONTROL (SEQUENCE OF
OPERATION)
Open, stop, close, close is programmable. Stop will override
all other functions. If closing, open will cause the operator to
stop and reverse to full open. Will close from open limit or
midstop only. If SW1 pin 1 is on three button station will only
close the operator from the open limit or from mid-stop. If
SW1 pin 1 is off, the input will work as a single button (open,
close, stop).

SINGLE BUTTON CONTROL (SEQUENCE OF OPERATION)
Open to open limit, close open. If power has been interrupted, will always open with first
activation.
CLOSE SINGLE BUTTON SELECT
The single button (programmable) control can be programmed to either function as a single button
control or to function as a close button only.
DIGITAL MICROPROCESSOR
This is the main circuit board for the operator. It contains all the logic and intelligence for the
system. All the system programming is done on this circuit board. All solid state, with an
emergency back-up system that works even if the processor is missing.
INHERENT OBSTRUCTION PROTECTION
The limit shaft is equipped with an R.P.M. sensor. When the gate meets an obstruction, the loss
of r.p.m’s. will cause the gate to reverse. A second obstruction will cause the gate to stop. A
renewed wired input will restart the gate.
