9.2 Searching for causes of fault
Fault Possible cause Measure
Piston rod does not extend. Tool jams.
Guiding columns are jammed. Mechanically decouple the Powerpack-
age and check ease of movement by
extending and retracting.
Air pressure too low (only for assembly
direction from the bottom to the top). Check air pressure and increase if nec-
essary.
Main control valve does not switch. Check main control valve.
Contact authorized service personnel.
Unlockable check valves (optional
equipment) do not open. Check non-return valves.
Contact authorized service personnel.
Faulty pneumatic hose. Check the compressed air supply.
Contact authorized service personnel.
No execution of power stroke.
Press force not reached. Insufficient air pressure. Increase air pressure.
Compressed air setting on pressure
regulator in the power stroke line (op-
tional) is too low. Increase air pressure in power stroke
line.
Pneumatic spring pressure setting is
too high or the pneumatic spring is
faulty. Check compressed air supply of the
pneumatic spring.
Contact authorized service personnel.
Oil level is too low. Checking oil level, Page 60 .
Air is trapped in the hydraulic oil sys-
tem. Refilling oil and venting drive, Page
61
.
Power stroke valve is faulty. Contact authorized service personnel.
Control throttle 'X' incorrectly set, over-
loaded. Setting control throttle 'X', Page 47 .
No air pressure in home position. Impinge the return stroke with air pres-
sure before initiating the fast approach
stroke.
Power stroke not triggered with
very short fast approach stroke
(only for type Q-S, X-S, S, EL
with hydraulic end position
cushioning ZHD) The fast approach distance traveled is
too short. Required: min. 8 mm. Set sufficient travel for fast approach
stroke before the power stroke is
switched on.
