UL325 ENTRAPMENT PROTECTION
PRIMARY ENTRAPMENT PROTECTION ADJUSTMENTS
Force Control
Set the force control pot such that the unit will complete a full
cycle of gate travel but can be reversed off an obstruction without
applying an unreasonable amount of force. On most operators
this will be around the middle of the range.
SECONDARY ENTRAPMENT PROTECTION ADJUSTMENTS
Terminals 9 & 5 - Obstruction While Opening
(Edge/Photo Eye Input)
Edge Input: See Programming Section on page 15.
This input will reverse an opening gate to the close limit.
Activating this input when the gate is closing will have no effect.
NOTE: If upon reversal a second separate obstruction is detected
(gate edge or RPM sensor), gate will stop and alarm.
Photo Eye Input: See Programming Section on page 15.
This input will pause an opening gate. Once the input (photo eye)
is cleared, the gate continues to open. Activating this input when
the gate is closing will have no effect.
Terminals 10 & 5 - Obstruction While Closing
(Edge/Photo Eye Input)
Edge Input: See Programming Section on page 15.
This input will reverse a closing gate to the open limit. When
reaching the open limit the Timer-to-Close, if enabled, will be
disabled until another command is given. Activating this input
when the gate is opening will have no effect.
NOTE: If upon reversal a second separate obstruction is detected
(gate edge or RPM sensor), gate will stop and alarm.
Photo Eye Input: See Programming Section on page 15.
This input will reverse a closing gate to the open limit. This input
will not affect the Timer-to-Close. Activating this input when the
gate is opening will have no effect.
