Operation

4.1

Switch-on/switch-off

!
Do not switch off the EPS 200 while component
testing is in progress (except in the case of emer-
gency stop). Always switch off the EPS 200 by way
of the central master switch on the front of the unit
before unplugging the three-phase AC connector.
Switch on the EPS 200 with the central master
switch on the front of the unit.
 After switch-on, the Windows operating system
starts up and then the EPS 200 system software.
Before switching off at the central master switch,
first end the EPS 200 system software and then shut
down the Windows operating system.
i
Prior to renewed switch-on, the EPS 200 must have
been switched off for at least 60 seconds.

Preparation for testing

R
Before every CRI Piezo test sequence, check the oil
level gage to ensure there is sufficient test oil in the
tank.
R
We recommend performing a leak test on a daily
basis. The leak test can be called up under "Service
>> Equipment diagnosis".
R
To prevent contamination of the test oil, every CRI
Piezo component must be cleaned before the test.
Do not clamp damaged, contaminated or severely
corroded CRI Piezo for testing.

Cleaning instructions for CRI/CRIN,
CRI Piezo and DHK/UI
!
Do not clean the nozzle cone with a brass brush,
steel brush or the like as this would damage the in-
jection orifices. Do not clean injection orifices with
the nozzle cleaning tool 0 986 611 140. Do not clean
the electrical connection of the injector with cold
cleaning agent.
1. Seal the inlet connection, return connection and noz-
zle cone of the injector/nozzle holder with protective
caps or cover over.
2. Use a plastic brush to remove any coarse dirt on the
injector/nozzle holder.
3. Pre-clean the injector/nozzle holder with cold clean-
ing agent.
!
Use the cleaning agent Tickopur TR 13 or a compara-
ble corrosion and coke-dissolving cleaning agent for
ultrasonic cleaning.
4. Remove the protective cap from the nozzle cone.
5. Attach the injector/nozzle holder to a suitable hold-
ing device and immerse it in the ultrasonic bath until
the nozzle retaining nut is completely covered by the
cleaning agent.
6. Set a cleaning temperature of 60°C to 70°C.
7. After approx. 15 minutes, take the injector/nozzle
holder out of the ultrasonic bath and blow dry with
compressed air.
i
After cleaning, always store injectors/nozzle holders
in a clean, closed container to prevent the injectors/
nozzle holders coming into contact with dirt parti-
cles (e.g. fluff, swarf).
i
Also heed the additional cleaning information in the
ESI[tronic] 2.0 component repair instructions.
