Guard locking type

TZ2	Open-circuit current principle, guard locking by control of AS-i output 0. Release by spring force.

Control of the guard locking solenoidThe guard locking solenoid is controlled by the control system via AS-Interface bus bit D0. In addition the 24V connection can be switched safely. AS-Interface inputs

D0, D1	Door monitoring contact SK
D2, D3	Solenoid monitoring contact UK

Evaluation is performed via a safety monitor. AS-Interface outputs

D0	Guard locking solenoid
D1	Red LED
D2	Green LED

LED function display

• The Power LED indicates the operating voltage on the bus.
• The Fault LED indicates if a fault 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.

Auxiliary releaseIs used for releasing the guard locking with the aid of a tool. A seal and auxiliary tool are fitted to protect against tampering.
