G2M Control Board Layout:
Description:
The Byan Systems G2M control board is a single phase, microprocessor controlled unit.
It is capable of controlling up to two 3/4 hp 115V or 220V AC motors. Board voltage is field
selectable with good soldering skills and high quality soldering tools. Three different plug-in
accessory cards are available for the G2M. A leaf delay card comes standard with every board.
A traffic light card and a receiver card are available separately. There are three timing
potentiometers as well as nine DIP switches incorporated into the board to control different
output functions.
Terminal Strips:
There are two sets of terminals on the G2M control board. The first terminal strip is the
power and motor run terminal block located on the left side of the board below the transformer.
This is where the incoming commercial power and the outgoing power to the operators are
connected.
The second terminal strip is the accessory terminal strip. This is where all accessory
connections are made.

Accessory Hook-Ups*:
There are many accessories available that are compatible with the G2M that will give the end
user different options for safety, security, and system operations. Since it would be impossible to
outline all possible combinations, we will simply outline a few of the most common. Keep in
mind; these instructions are specific to the brand and model most commonly used by Byan
Systems. Your accessories may differ from the ones listed below. Always consult the
Installation Instructions included with an accessory before connection it to any operating system.
Linear GRD_1 Radio Receiver:
1. Separate the four wires coming out of the bottom of the receiver (1 Red, 1 Black, & 2
Gray).
2. Connect the black wire to terminal 3 of the accessory terminal strip.

Trouble Shooting Guide:
Symptom
Possible Cause Possible Solutions
Board will not
power up
Power not connected,
switch in prewire not
turned on, board
voltage of board
incorrect, blown
incoming power fuse
Ensure all connections are made and are tight, make sure
switch in prewire is on, make sure board voltage matches
incoming power, check 2A fuse on the G2M
Board is
powered up but
won’t function
Jumper wires in
accessory terminal
loose/missing, safety
device malfunctioning,
blown operator fuse
Check all jumper wires for location and make sure they are
tight, make sure safety devices are clear of obstruction and
connected properly (the G2M uses N/C safety contacts),
check 6A fuses on the G2M
Operations will
not open or
close fully
Timers not adjusted
properly, dip switches
are in the wrong
position
Timers should be adjusted so operator pistons bottom out
completely then run for an additional 3 – 5 seconds, make
sure all dip switches are in the desired location and making
good contact
Operators run,
but there is no
piston
movement
Capacitor bad or not
hooked up, bypass
screw on operator
backed out
Check that capacitors are hooked up, if one is suspect,
switch capacitors and see if the problem follows the
capacitor, make sure bypass screw is screwed in and snug
Safety devices
connected
properly but not
functioning
properly
Jumpers in term. 8, 9
& 10 are still in, safety
device is
malfunctioning
If car safe is used, make sure that the jumper between
accessory terminals 9 & 10 is removed, for people safe,
remove jumper between accessory terminals 8 & 9, make
sure the safety device is connected and working properly
Radio receiver
will only open
the gate
Radio receiver is
wired incorrectly
If the receiver is to be used as a reversing device, it must be
wired across accessory terminals 16 & 19
Free exit probe
not working
Probe is
malfunctioning, probe
is wired incorrectly
Make sure probe is working properly and is connected
correctly, probe’s N/O contacts must be connected across
accessory terminals 16 & 18, if the probe uses 24V AC for
power, it can be connected to accessory terminals 3 & 4
Operators
running the
wrong direction
Directional wires
switched
Reverse the black and red directional wires either at the
operator or at the board
If at any time you have a question concerning G2M control board, call 1-800-223-2926 for
technical support.

T2M Leaf Delay Card
Description:
The T2M Leaf Delay Card will control the opening and closing of the second leaf in a
two-leaf gate system. With the card installed and the potentiometers adjusted, the first gate leaf
will open fist followed by the second when an open command is issued. When a close command
is issued, the second leaf will close first followed by the first leaf. There are two adjustable
potentiometers on the card. The open delay timer sets the delay between the opening of the first
leaf and the opening of the second leaf. The close delay timer set the delay between the closing
of the second leaf and the closing of the first leaf. There are also inputs on the card for open and
close limit switches for the second leaf if limit switches are required.
Adjustable Timers:
Timer Description Minimum Delay Maximum Delay
Open Timer (Left) 0 Seconds 15 Seconds
Close Timer (Right) 0 Seconds 15 Seconds
Board Terminals (Numbered bottom to top):
1. Motor Two Limit Switch Common
2. N/C Motor Two Close Limit Switch
3. N/C Motor Two Open Limit Switch
Installation Instructions:
1. To install the leaf delay card, simply plug it into the card slot marked “2 Motor Card”
on the G2M.

Adjustment Procedure:
1. To set the amount of delay between the first leaf opening and the second leaf opening,
turn the open delay time (left timer) with a small screwdriver. To increase the open
delay, turn the timer counterclockwise. To decrease the open delay, turn the delay
timer clockwise.
2. To set the amount of delay between the second leaf closing and the first leaf closing,
turn the close delay timer (right timer) with a small screwdriver. To increase the
close delay, turn the timer counterclockwise. To decrease the close delay, turn the
timer clockwise.
