Description

Guard locking type

TZ1

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

Control of the guard locking solenoid

The 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 ÜK

Evaluation is performed via a safety monitor.

AS-Interface outputs

D0

Guard locking solenoid

D1

LED red

D2

LED green

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.

Emergency release

It is used for manual release of the guard locking without tools in an emergency. The emergency unlocking mechanism must be returned to the locked state manually. A sealing wire is fitted to protect against tampering.
