Smart DC Controller Troubleshooting
6-18 SlideSmart DC Installation and Reference Manual Revision D
DEAD BATTERY Extremely low UPS batteries – no
automatic operation - batteries
below 21V.
Occurs when the battery voltage has dropped to less than
21V. At this level, the batteries are 90% depleted. The gate
will automatically open or close depending upon the setting
chosen. Refer to AP - AC LOSS
User Menu. No
additional automatic function is possible, but limited push
button control is available to 18V.
1. No AC Power. See above item.
2. Wiring / Connector problem - check all
connections. Clean or repair as required.
3. Check battery condition.
4. Smart DC Controller charger failure - check
charger voltage and replace Smart DC
Controller.
5. Transformer failure - replace Transformer.
HYSECURITY
BAD POWER
Critically low 24V supply power.
This message can occur only on
initial start up if power is critically
low.
DC power is below 14V – no control functions will be
allowed at all.
1. No AC Power. See above item.
2. Wiring / Connector problem - check all
connections. Clean or repair as required.
3. Check battery condition.
No display, LED blinking Smart DC Controller is receiving
power, but battery voltage is very
low.
Several possible causes:
- The AC power has been shut off from the operator for too
long and the batteries are drained.
- Wiring problem.
- Batteries no longer hold a charge.
- Bad Smart DC Controller.
- Bad transformer.
1. No AC power. See item above.
2. Wiring/Connector problem - check all
connections. Clean or repair as needed.
3. Check battery condition.
4. Smart DC Controller charger failure - check
charger voltage and replace Smart DC
Controller.
5. Transformer failure - replace transformer.

ALERT 1
FORCE OPEN
Gate forced open. The gate has been forced open from a full close limit and is
being prevented from re-closing.
Will self-clear after an open or close input.
ALERT 2
DRIFT CLOSED
Gate drifted closed. The gate has drifted closed from a full open limit and is
being prevented from re-opening.
Will self-clear after an open or close input.
ALERT 3
EXCESS DRIFT
Gate drift in transit - Advisory only The alert appears if the gate drifts three times in a five
minute period.
Check the track to make sure it is level.
ALERT 4
MOTOR OVERLOAD
Thermal overload alert. When the
alert is triggered, the gate can only
“fully open” until the alert is cleared.
Motor drive heat sink exceeds 210°F. The alert will
temporarily disable the operator, but will automatically
reset itself when it cools down.
Check gate hardware, weight/length of gate.
Alert automatically clears when the temperature
drops below threshold.
ALERT 5
