3) "Measurement" key
4) Pause LED
5) Control key "Off"
6) Supply voltage LED
7) Control key "On"
¶
Switch on and adjust the voltage stabilizer to 24 V
(DC), position the current regulator to "Maximum".
Self-test of the CRR 220:
After the CRR 220 has detected the voltage supply,
each of the three LEDs light once, from left to right, as
a test function.
Subsequently, the software version within the device
is output by coded flashing of the LED.
For example, for the software version V01_2_0:
¶
The LED (Fig. 7, Pos. 6) flashes once, the LED
(Fig. 7, Pos. 4) blinks twice and the LED (Fig. 7,
Pos. 2) does not blink.
¶
After a successful self-test, the LED blinks (Fig. 7,
Pos. 6). This indicates that the supply voltage is
available and the device can now be switched on.
