6.2.2 Measurements with High Pressure Inlet, (max. 350 bar)
Figure 7 : Setup for measurements with high pressure inlet
A
Plug the return hose (DN 7) onto the "Outlet" connector on the back panel and route it into
a suitable container, e.g. hydraulic tank or any other container.
B
Switch the pump switch on the rear panel to OFF position (refer to Figure 3 : Rear View)
and turn the flow control valve on the front panel to position 5.
If the pump is not switched off, it can be damaged !
C
Set the ball valve on the rear of the FCU to position INLET (refer to Figure 7).
D
Determine the system pressure of the test point to be checked and see whether it is within
the permissible range for the pressure connection (inlet, 1 - 350 bar).
E
First connect the high pressure measuring hose to the FCU and then to the Minimess
connector of the hydraulic test point.
As soon as the pressure connection has been made to the system and
a measurement is started (remind: autostart function !), the oil flows
through the FCU. That is why it is important that connection be done in
the sequence indicated above. The outlet must never be blocked or
closed off!
F
Switch the FCU on, wait until it is ready, select Mode M5 (see chapter 7.1 Measurement
Operation), then press the
START
key. Set the flow rate to approx. 70ml/min. (shown in
LCD). If an error message appears in the LCD, turn the flow control valve in the direction
indicated until the error message disappears and measurement operation starts
automatically.
