Under various entrapment conditions the operator will assume either a SOFT or HARD (alarm) shutdown. To determine what
type of reset action is required, you will need to understand how the different entrapment conditions affect the gate operator.
This occurs in various situations where the inherent or external entrapment protection devices have been activated. In a soft
shutdown condition, the operator will not respond to any input that was present when the entrapment protection device sensed
or encountered an obstruction. If the gate stops at the open position, the operator will not respond to the automatic close timer
and a “manual input” is required to close the gate.
Note: In some systems, the time clock input comes from the telephone entry system relay. This same relay may also
provide open commands for a card reader, MicroPLUS transmitters and the visitor telephone entry. If so, these devices
will also be disabled in a soft shutdown condition.
• Example 1 - A time clock keys the gate open in the morning and an entrapment protection device senses
an obstruction prior to the gate reaching the full open position. If the entrapment is sensed by the inherent
system, the gate will reverse and run back to the closed position. The time clock input is still present, but
the gate will not re-open.
Soft Shutdown
In some conditions, a soft shutdown will reset as soon as the entrapment condition clears. For example, if a non-contact
sensor (photo sensor) is sensing an obstruction, the operator will stop the gate and assume a soft shutdown condition. When
the photo sensor clears (Obstruction is no longer there), 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 input device, any standard safety input device 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 external or inherent device was activated.
The automatic close timer will not close the gate.
• Example 3 - If a moving vehicle runs over a loop while the gate is cycling open and hits the opening gate, the
operator’s inherent entrapment protection is activated. The gate will reverse direction and run back to the
closed position. A soft shutdown condition does not occur and the loop provides an immediate reset of the
operator. Once the loop area is clear and another open command is given, the gate will cycle open.

3.6 Shutdown Conditions
When the operator is in a soft shutdown, the system WILL NOT shut down power to the circuit board until an “intended
input” has been activated regardless of the length of time it takes to accomplish this (See the paragraph above).
3.5 Radio Receiver Continued
Set to LOW - Power Mode
2. Press and hold Program Button until the Program LED flashes ONCE and receiver will BEEP once.
3. Receiver LED will then give a long flash and beep.
4. This indicates receiver is in LOW-Power mode which consumes LESS power than NORMAL-Power mode.
The receiver can be changed from normal-power to LOW-Power
mode. LOW-power mode is used in DoorKing solar gate operator applica-
tions. Wiegand output will NOT work in LOW-Power
mode.
