Prior to testing

Check the following items before switching on the
EPS 815:
R
Is the test equipment properly connected?

measurement channels to be used with the KMA. At
least four of these must be connected to quantity
measurement channels 1, 2, 5, 6, 9 or 10.
R
Have the protective devices (e.g. protective hood)
available, complete, and functional?
R
Has the component to be tested (e.g. CP4) been
properly clamped and connected (hydraulically and
electrically)?

Starting the test procedure

Warning - danger of injury due to escaping
test oil or flying parts!
If the hydraulic connections for the test
equipment and common rail pump are
set up incorrectly, test oil can escape at
high pressure or components of the test
equipment can burst when the test is
started. This can cause injury or material
damage.
¶
Before switching on, check that all
hoses on the test equipment and
the common rail pump are properly
connected.
¶
Do not open the splash guard until
the EPS drive motor has come to a
standstill
¶
Replace any leaky or faulty hose lines.
!
If a high-pressure hose connection is leaking,
the screw coupling must not be tightened any
more firmly. In the event of a leak, unfasten the
connection, clean the sealing surface and re-
connect the high-pressure hose.
Procedure:
1. In the EPS 945 software, call up the desired test
sequence in the 'Component selection' dialog box.
2. Call up the measurement screen.
3. Select test step '1'.
4. In the 'Measuring functions' selection menu,
activate the Automatic On/Off function.
 The automatic mode symbol flashes in the oper-
ating status display.
5. Press <F8> to start the test.
6. In the 'Measuring functions' selection menu,
activate the Channel detection function.
 The software automatically detects the active
measuring channels.
