Smart DC Controller Troubleshooting
6-18 SwingSmart DC Installation and Reference Manual Revision E
DEAD BATTERY Extremely low UPS batteries – no
automatic operation - batteries
below 21 Volts.
Occurs when the battery voltage has dropped to less than 21 Volts.
At this level, the batteries are 90% depleted. The gate will
automatically open or close depending upon the setting chosen.
Refer to
Setting AC Power Loss Gate Function
. No
additional automatic function is possible, but limited push button
control is available to 18 Volts.
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.
HYSECURITY
LOADER
The Smart DC Controller cannot
locate the system software or
software is being loaded into the
Smart DC Controller.
There is no software loaded on the Smart DC Controller or
software is being loaded.
Load the latest software version (H5.XX) using
START with a download cable (preferably
USB) or wait for software to finish loading.
ALERT 1
FORCE OPEN
Gate forced open. The gate has been forced off its closed limit and is being
prevented from re-closing. Must be enabled in User Menu.
Will self-clear after an open or close input.
ALERT 2
DRIFT CLOSED
Gate drifted closed. The gate has been forced off its open limit and is being
prevented from re-opening. Must be enabled in User
Menu.
Will self-clear after an open or close input.
ALERT 3
EXCESS DRIFT
Not used in SwingSmart.
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.
