If the ICR is installed in a machine/panel with the result that the warning labels are no
longer visible, additional warnings (not included in the scope of delivery) must be
provided on the machine beside the emergence aperture of the LED radiation.
Activation and deactivation of the LEDs when reading is controlled by the reading pulse
(trigger source).
A timer (illumination timeout) automatically deactivates the LEDs 10 minutes (default
setting) after a continuous reading pulse is initiated in Reading mode with switching input
pulse modes “Sensor Input“ and “Serial Interface“. However, it does not end the reading
interval. In this case, the ICR outputs the following message to the auxiliary interface:
“Illumination safety timeout“
The reading interval must be terminated by resetting the trigger signal. The LEDs activated
again by the next reading pulse.
The illumination timeout can be set in the range of 1 min to 25 h or deactivated (see
).
The Illumination LEDs are periodically activated in the operating mode “Percentage
Evaluation“ and are always activated in the pulse mode “Free Running“ in Reading
mode.

Quick stop and quick restart
2.4.1
Switching the ICR off
¾
Switch off the power supply or remove the ICR cable plug from the connection module.
This can result in loss of the following (at the most):
•
The application-specific parameter set, if it was only stored
temporarily
in the ICR
•
The last reading result
•
Daily operating data
(operating hours counter, reading interval count, good read count, no read count,
maximum duration reading interval, minimum duration reading interval, number of
matches with match code 1, number of matches with match code 2, number of No
Matches.)
2.4.2
Switching the ICR on again
¾
Switch on the supply voltage or reattach cable plug of the ICR to the connection module.
The ICR resumes operation with the
last permanently stored
parameter set and resets
the daily operating data.
