CTM-L2-AS1B-U-ZZ-SJ-P-163972 (Order no. 163972)

Description

Guard locking type

CTM- L2

Open-circuit current principle: guard locking by control of AS-i output 0 and release by spring force.

Control of the guard locking solenoid

The guard locking solenoid can be controlled via AS-Interface bus bit D0 or via the auxiliary power.

AS-Interface inputs

D0, D1

Door monitoring

D2, D3

Guard lock monitoring

Evaluation is performed via a safety monitor.

AS-Interface outputs

D0

Guard locking

LED function display

  • The ASI LED indicates the state of the ASi bus.
  • The LOCK LED indicates the state of the guard locking.
  • The STATE/DIA LED indicates the state of the switch and possible errors.
