Description
Approach direction
Horizontal
Can be adjusted in 90° steps
Guard locking principle
Open-circuit current (power on to lock): On a guard with guard locking based on the open-circuit current principle, the guard is locked until the power supply to the guard locking solenoid is interrupted. Unlocking is by spring force. The term electrical guard locking is also used.
Multicode evaluation
The system checks whether the actuator type is one that can be recognized by the system (multicode evaluation). The system has a low coding level. Every suitable actuator is recognized by the switch.
Control of the guard locking solenoid
The guard locking solenoid is controlled via AS-Interface bit D0.
Auxiliary voltage
The ASi auxiliary voltage is required for the device's mode.
AS-Interface inputs
D0, D1 | Monitoring of the guard position |
D2, D3 | Guard lock monitoring |
AS-Interface outputs
D0 | Control of guard locking |
D1 | LED red |
D2 | LED green |
LED indicator
The ASi LED indicates the operating voltage on the bus.
The STATE LED indicates when an error has been detected on the AS-Interface bus.
The green and the red LEDs can be controlled as required by the control system via the bus using bits D1 and D2.
