BYAN G2M CLASSIC CONTROL BOARD | Rev. 2019.6.1
Troubleshooting Guide:
Byan Systems recommends that ALL installations be preassembled PRIOR to installation on a job
site to insure proper functioning.
Symptom Possible Cause Possible Solutions
Board will not
power up
Power not connected;
Switch in prewire not
turned on; Board
voltage is incorrect;
Blown incoming power
fuse
Ensure all connections are made and are tight (make sure that
terminal blocks on Pins 1 & 2 for high voltage are secure) . Make
sure the prewire switch is on. Make sure board voltage matches
the incoming power. Check 2-Amp fuse on the G2M board.
Board is
powered up but
won’t function
Jumper wires in
accessory terminal are
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 Normally Closed safety contacts). Check
6-Amp fuses on the G2M board.
Ensure that both of the
Accessory Connection Terminal Blocks are secure (Pins 1-7 and
8-19)
.
Operators 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 to 5 seconds. Make sure
all dip-switches are in the desired position 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 the bypass screw is screwed in and snug.
Safety devices
connected
properly but
not functioning
properly
Jumpers in Terminals 8,
9 and 10 are still in;
Safety device is
malfunctioning If Car Safe is used, make sure that the jumper between Accessory
Terminals 9 and 10 is removed. For People Safe, remove jumper
between Accessory Terminals 8 and 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 and 19.
Free exit probe
not working
Probe is
malfunctioning; Probe
is wired incorrectly
Make sure probe is working properly and is connected correctly.
The probe’s Normally Open contacts must be connected across
Accessory Terminals 16 and 18. If the probe uses 24-Volt AC for
power, it can be connected to Accessory Terminals 3 and 4.
Operators
running the
wrong direction
Directional wires
switched Reverse the black and red directional wires either at the operator
or at the board.
