Operation

Fig. 7: Operation
1) Connection socket for the Bosch Common Rail Injector (adapter
required)
2) Ready for measurement LED
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 24V (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 (6) flashes once, the LED (4) blinks twice and
the LED (2) does not blink.
After a successful self-test, the LED blinks (6). This indi-
cates that the supply voltage is available and the device
can now be switched on.

Starting the measurement:
Press push-button (Fig. 7, Pos. 7) the device is now
switched on.
By lighting, the LED (Fig. 7, Pos. 6) and the LED (Fig. 7,
Pos. 2) indicate the operational readiness of the
CRR 220.
Now you can start the actuation of the Common Rail
Injector by using the "Measurement" key (Fig. 7, Pos. 3).
After a successful actuation, LED (Fig. 7, Pos. 2) turns
off and the flashing LED (4) indicates the programmed
measurement pause.
!
In order not to overload the solenoid coils, the actua-
tion of the Injectors by the CRR 220 is stopped for
about 30 seconds after each test. This is indicated
by LED (4) flashing. Manipulation of this function by
switching the CRR 220 off and on is not permitted!
After the measurement pause, the CRR 220 is ready for
operation again; this is indicated by the LED
(Fig. 7, Pos. 2) lighting. Another actuation of the test
object can now be performed.
Once you have finished the measurement, switch the
CRR 220 off with the control key (Fig. 7, Pos. 5).

Fault correction

8.1 The CRR 220 cannot be switched on;
LED (6) is not lit:
Possible faults:
The CRR 220 is not operated with an operating voltage
of 24 V (DC) or the voltage regulator in the voltage sta-
biliser is not set to 24V.
The CRR 220 was connected with reverse polarity.
8.2 The CRR 220 does not sufficiently
actuate the Injector or the actuation
is stopped.
Possible faults:
The voltage stabiliser does not provide enough power
for the actuation of the Injector, or the current regulator
is not set to "Maximum".
The mains power circuit is faulty.
