8) Turn the adjustment screw Counter clockwise HALF a revolution.
9) Repeat step 7).
IF step 7) was still fulfilled,
THEN return to step 8),
ELSE continue below.
10) Turn the adjustment screw CLOCKWISE ONE QUARTER of a revolution.
11) Repeat step 7).
IF step 7) is now fulfilled again,
THEN turn the adjustment screw Counter clockwise 1/8 of a revolution,
ELSE turn CLOCKWISE 1/8 revolution.
Now the excess pressure should be equal to or very close to the P1 trip point pressure:
FWD: approx. 40 bar (560 psi)
HWD: approx. 60 bar (850 psi)
best indicated by a flickering P1 LED (while the LC button is pressed).
Once the P1 trip point pressure has been established, then the excess pressure should finally be
increased by turning the adjustment screw CLOCKWISE ¾ (three quarters) of a revolution. This
is the FINAL setting. Refer to steps 14) and 15) below for re-application of washer, O-ring and
dome nut.
If a pressure gauge is available, then adjust the excess pressure as follows (make sure that steps
1) and 2) have been performed):
12) Apply a (optional) pressure gauge (range 100 bar or 1000 psi) to the “quick-connect” stud
on top of the hydraulic block.
13) Adjust the excess pressure adjustment screw in 1/8-revolution increments (CLOCKWISE
for higher pressure, COUNTER clockwise for lower pressure) until performance of step
7) gives a pressure reading of
FWD: 60-70 bar (800-1000 psi)
HWD: 75-85 bar (1050-1200 psi).
14) Tighten the adjustment screw lock nut WHILE retaining the adjustment screw, so that
this does not change setting.
15) Re-apply the O-ring, washer and dome nut: MAKE SURE that the O-ring is positioned
“inside” the washer, so that it will not be sheared when the dome nut is tightened.
16) Make sure that step 7) checks out OK, otherwise P1 is defective and must be exchanged.
11.4 Electrical System
11.4.1 Transducers
The transducers, i.e. the Load Cell and the Deflectors, are connected to sockets at the Compact15
front panel. Refer to descriptions in the following.
Refer to Section 12, “Transducers/Cables” for descriptions of the transducers and for cable
wiring diagrams.
