Troubleshooting Codes: Table 3
Type Alert/Fault/Error Display Buzzer Chirp Sequence Possible Cause & Suggested Corrective Action
ALERT HYSECURITY
ENTRAPMENT MODE
2 chirps per second every
2s while control input is
active
An emergency close with constant hold or an emergency open
has caused the entrapment code to appear. When a command
of this nature is received, the operator stops and moves into
ENTR mode. Clear the code and return to run mode operation,
by pressing the Reset button.
ALERT HYSECURITY
SAFE MODE
2 chirps once when in Safe
Mode
An gate “edge” has been tripped or the operator has exited
entrapment mode. Refer to the description above.
NOTE: Gate will operate, if it receives a RUN command.
ALERT LOW 24VDC
DC BUSS < 21V
No chirps; LCD ashes for
1s every 5s
Only occurs in DC powered operators.
ALERT CRITICAL LOW POWER No chirps: LCD steady and
controls disabled
The system monitors the 24V control voltage in lieu of line
voltage. Low incoming line voltage will cause low control
voltage. Verify that the control transformer is connected
properly, (white – not used, red for 208V, orange for 230V and
blue for 460 V). Refer to Control Transformer Connections (Non-
UPS) on page 21. Check the line voltage, as the motor starts,
with a meter that has min/max hold capability. If the line voltage
drops more than 10% below nominal (187 on 208 VAC, 207 on
230 VAC, or 416 on 460 VAC) the voltage is dropping too much
and must be corrected. Generally, this requires larger wire size.
On 3-Phase operators, check each leg of to ground to make
sure it is balanced.
If the line voltage is not dropping below these limits, check the
24V AC and DC power at the power supply. Voltages less than
20V indicate an overloaded or failing transformer or power
supply board. Remove the loads until the fault is found.
ALERT DEAD BATTERY
DC BUSS < 21V
3 chirps upon any
operating command entry
DC operators only. Appears when the 24 VDC power drops too
low, disabling the operator to prevent damage to the batteries
from excessive discharge. Verify the AC power is present at the
charger, the charger is on and charging (Red LED is illuminated).
The charger should shut off (Green LED) when the batteries
charge to 29.0 VDC. If the batteries will not “hold a charge”
replace them.
ALERT NO AC POWER Chirps once whenever the
gate reaches the close
limit
AC power is shut off at the source (breaker) or is not connected.
The AC power switch on the operator (lower rocker switch) is
turned off, or the circuit breaker on the operator has tripped.
• Have a licened electrician check the wiring.
• Connect AC power to the operator.
• Reset circuit breaker at the electrical panel.
• Reset the operator circuit breaker.
• Turn AC power switch on.
ALERT ALERT 1
FORCED OPEN
2 pulses per second for
30s
Set FA 1 in the User Menu, to enable this option. The operator
will attempt to re-close itself if forced off the close limit switch,
the buzzer sounds for 30 seconds. Check for attempted
unauthorized access, external pressure trying to open the M30/
M50 gate or a mis-adjusted/failed closed limit switch.
