LOWER
See el-servo diagram (S)
1. Control lever used to LOWER, P1 gives a 5-1 V analogue
signal via D sub-contact S42.8, via cable S33 to X55.1
2. ANA IN S2.42. No indication in ECU2 for analogue IN sig-
nals.
3. DIG OUT S2.50. (Opens the lift cylinders’ blocking valves
S15). LE12 lit.
4. 24 V to X62.7.
5. X69.7
6. 24 V to the blocking valves S15, right and left, that open.
7. ANA OUT S2.04 to X63.2
8. Varies 24V between X63.2 and X63.5.
9. Main valve converter S7.2 opens for servo pressure at the
same time servo pressure is fed to S7.8.
10. Main valve section S7.2 and S7.8 opens for LOWER
Conditions:
No alignment indication from attachment, LE14 extin-
guished.
Dead man’s grip activated, LE19 lit.
No front overload, no steering axle overload (Module 50:
LE21 extinguished. Module 60: No overload indication on the
display).
Emergency lowering
In the event of an electrical fault that leads to the blocking valves
on the lift cylinders being unable to be opened, i.e., the boom
cannot be lowered, there is an emergency lowering function.
On the solenoid S15 for the blocking valves (right and left lift cyl-
inders) there is a knob, A in the illustration. Pull this straight out
and turn it one quarter turn and the boom will slowly lower.
NOTE: The emergency lowering applies to unloaded machine
only.
