Operating and Display Elements
3.4.1
Key Switch
The key-operated switch interrupts the flow of current to the laser sensor for
maintenance purposes. When the switch is in the "Off" position, the associated green
LED goes out and the sensor plug can be withdrawn.
3.4.2
Reset Button
On pressing the Reset button a program restart is initiated in the controller,
corresponding to a "power-on reset".
3.4.3
Mode Button
The saved operating modes can be selected in a cyclic manner with the "mode"
button. Also, the parameters configured by software can be permanently saved in the
controller with the Mode button (see Chap. 11).
3.4.4
LED Indicators
Light emitting diodes on the controller signal:
power on
:
The green "power on" LED lights when the operating voltage is applied.
laser on
:
The green LED is out when the laser is off (see Chap. 3.3.5).
The LED "laser on" also may light, if no sensor is connected.
error
:
The red error LED signalizes different error states by different blinking
schemes (see Chap. 13.3).
control
:
Communication with PC. The green LED also blinks,
• long during an active data transmission and
• short for control access.
mode 1 / 2
: The yellow LEDs indicate the current
operation mode.
A green light emitting diode on the sensor signals "laser on".
