Fault Correction; The Crr 220 Cannot Be Switched On; Led; Is Not Lit; The Crr 220 Does Not Sufficiently Actuate The Injector Or The Actuation Is Stopped - Bosch CRR 220 Betriebsanleitung

Starting the measurement:
1. 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 readi-
ness of the CRR 220.
2. 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 (Fig. 7, Pos. 4) in-
dicates the programmed measurement pause.
!
In order not to overload the solenoid coils, the
actuation of the Injectors by the CRR 220 is
stopped for about 30 seconds after each test.
This is indicated by LED (Fig. 7, Pos. 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 actua-
tion of the test object can now be performed.
3. 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
stabilizer is not set to 24 V.
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 stabilizer 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.
