MODEL 600 SERIES OPERATOR | Rev. 2019.7.1
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 block 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.
Safety Device(s)
only monitoring in
the Close
Function
DIP Switch 7 is in the OFF
position
When turned on, car safety contacts are active during the open and
close cycles. Input safety for vehicles only works on closing
movement unless Switch 7 is set ON.
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.
If, at any time, you have a question concerning the Byan Systems G2M+ control board, call (800) 223-2926 for
technical support.
