NOTE: The audio alarm will remain activated for a maximum of five minutes, or until the operator receives a reset input.
The hard shutdown condition will remain in affect even if the audio alarm shuts off after five minutes.
In some conditions, a soft shutdown will reset as soon as the entrapment condition clears. For example, if a
non-contact sensor (photo cell) is sensing an obstruction, the operator will stop the gate and assume a soft
shutdown condition. When the photocell clears, the operator will return to normal operation.
When the operator is in a soft shutdown, activation of any "intended input" will reset the operator. An "intended
input" includes any command, any standard safety input and any loop input. Activating any of these inputs will reset
the gate. At that point the gate will return to normal operation. If the gate is open, the automatic close timer will
then time out and close the gate.
• Example 2 - If the gate is closing and an entrapment protection device is activated, the gate will either stop
or reverse and run back to the open position, depending upon if the secondary or inherent device was
activated. The automatic close timer will not close the gate.
• Example 3 - Vehicle arrives at open loop and gate runs towards the open position. The inherent entrapment
protection is activated. The gate reverses and runs back to the closed position. If the vehicle is still present
at the open loop a soft shutdown condition does not occur. The loop input provides an immediate reset of
the operator and the gate will again run to the open position.
• Example - The gate is closing and the inherent entrapment protection system senses an obstruction and
causes the gate to reverse direction. As the gate begins to run in the open direction, a second obstruction
is sensed prior to the gate reaching the full open position. Once the second obstruction has been sensed,
the operator will stop, the audio alarm will be activated and all standard inputs are shut down (including
open commands, safety commands, loop inputs, etc.).
• After 5 minutes, the audio alarm will “chirp” every 5 seconds. This indicates that the operator is in a hard
shutdown condition and the reset switch must be activated to reset the operator and silence the alarm.
Resetting a Soft Shutdown
A hard shutdown condition occurs when the inherent entrapment protection system has sensed two consecutive
obstructions before the gate reaches the full open or closed position.
Hard Shutdown
NOTE: DoorKing operators have a built-in alarm reset push buttons on the circuit board and on the bottom of the
control box for quick access. Activating either one of these buttons will return the gate operator to normal opera-
tion, but will not activate the gate operator.
When the operator is in a hard shutdown condition (audio alarm activated or audio alarm “chirps” every 5 seconds),
the only way to reset the gate operator and return it to normal operation is to activate the alarm reset input
(auxiliary terminals 2 and 3). An alarm-reset switch can be mounted external of the gate operator provided that it is
installed in the line of sight of the gate and gate operator.
Once the gate has been reset, an open or close command is needed to start the gate operator. Most activating
commands will cause the gate operator to cycle to the open position. This includes activation of a key switch or
open command and activation of an open loop. Activation of a close command will run the gate to the closed
position.
• Before resetting a hard shutdown, determine why the shutdown occurred. Inspect the gate for any
obstructions along its path that could have activated the inherent entrapment sensing system. Inspect
the gate and gate hardware.
