Operation

4.1

Switch-on/switch-off

¶
Use the central main switch on the front of the unit
(see fig. 1, item 6) to switch on the EPS 200 / 205.
 After switch-on, the Windows operating system
starts up and then the EPS 200 system software.
¶
Before switching off at the central main 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 / 205 must
have been switched off for at least 60 seconds.
i
Do not switch off the EPS 200 / 205 while com-
ponent testing is in progress (except in the
case of emergency stop). Always switch off the
EPS 200 / 205 by way of the central main switch on
the front of the unit before unplugging the three-
phase AC connector.

Preparation for testing

R
Before every CRI Piezo test routine, 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 ba-
sis (sealing plug with connection adapter). 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 and/or se-
verely corroded CRI Piezo for testing.

Cleaning instructions for CRI Piezo

!
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.
