No later than 5 minutes after successfully teaching in the actuator, disconnect and
restore the voltage supply to the safety switch. Otherwise, the device changes to
the safe state.
✓
The safety locking device is ready for use.
7.1.2
Teaching in replacement actuators
Overview
The safety locking device can only be operated using the actuator that was last taught
in.
Important information
NOTE
Safety locking devices with an actuator that has already been taught-in have a teach-in
readiness of approx. 5 minutes after being switched on. During this time window, the
following applies:
•
If the currently valid actuator is detected, then the teach-in process is canceled.
The safety switch goes into normal operation.
•
If a deactivated actuator is detected, then the actuator is ignored and the previous
actuator remains valid. The teach-in time window remains active, however. The
teach-in process starts as soon as a new actuator is detected.
•
The device saves the last three deactivated codes only. Actuators that were taught-
in at an earlier time can be taught-in again.
•
The teach-in process is invalid if canceled, e.g. by interruption of the voltage supply
or premature removal of the actuator. The safety locking device then goes into the
safe state.
Approach
1.
Open movable physical guard.
2.
Disconnect safety switch from voltage supply for at least 3 seconds.
3.
Connect safety switch to voltage supply (
see "Electrical installation", page 25
).
✓
The start sequence is executed. All LEDs flash with alternating colors. OSSDs are
switched off in the meantime.
4.
Close movable physical guard.
✓
When the movable physical guard is closed and the actuator has reached the
required position, the safety switch automatically starts the teach-in sequence.
The individual steps are indicated via the LEDs.
