Gate command sequence - Open, Stop, Close, Stop, ...
Soft open (maintained switch does not override external safeties and does not reset alarm condition)
Acts as hard open.
Maintained input overrides (ignores) external safeties (photoelectric sensor and edge), pauses Timer-to-Close
momentary input logic as single button control and safeties remain active, re-enables Timer-to-Close.
Open command - opens a closed gate.
Soft open (maintained switch does not override external safeties and does not reset alarm condition)
If maintained, pauses Timer-to-Close at OPEN limit.
Opens a closing gate and holds open an open gate.
Loop detector connection when loop is positioned under gate.
- Holds open gate at open limit
- Disregarded at CLOSE limit and during gate motion
- Pauses Timer-to-Close at OPEN limit
CLOSE EYES/Interrupt Loop detector connection when loop is along the side of the gate.
- Holds open gate at open limit
- Stops and reverses a closing gate to open limit
- Pauses Timer-to-Close at OPEN limit
Close Direction Photoelectric Sensors, IR, or Infra-red detector wired to CLOSE EYES Input, disregarded during gate
opening.
Pulsed Photoelectric Sensors = monitored device putting out a pulse train when unblocked.
Photoelectric Sensors, IR, Infra-red detector, contact opens fully with obstruction.
Close Direction Edge Sensor to Close Safety Input, disregarded during gate opening
Open Direction Photoelectric Sensors, IR, Infra-red detector wired or Edge Sensor to Close Entrapments Input,
disregarded during gate closing,
Pulsed Photoelectric Sensors = monitored device putting out a pulse train when unblocked.
Photoelectric Sensors, IR, Infra-red detector, edge sensor = normally open contact, contact reverses for 2 seconds
with obstruction.
Commercial Link (two wires) - connects two operators together (primary-secondary wired connection)
Relay contact output, Normally - closed (N.C.) output for maglocks
Relay activates prior to motor activation and during motor run. Relay is off when motor is off.
Normally - open (N.O.) output for solenoid locks
Relay activates prior to motor activation and during motor run. Relay is off when motor is off.
24 Vdc voltage out to power accessories, will turn off when gate is not in motion to save battery power
Always on if Expansion Board is connected.
24 Vdc voltage out to power accessories, always ON
