Owner’s Manual

Cobra 501

• Fault:  No  or  insufficient  lubricant  supply  with  correct  position  of  the  lubrication  head  on  the  lubrication  nipple

•

Cause

• Faulty  lubricant  supply,  e.g.  supply  pump  defective  or  too

little lubricant in the reservoir, leakage in the lubricant line.

• Inlet air pressure too low for the cylinder of the lubrication

head.

•

Remedy

* Check  the  inlet  lubricant  pressure  (see  5.2).  Check  the

supply  pump  and  the  lubricant  lines.

* Check the air supply system of the cylinder of the lubricati-

on  head  for  leakage.

* Check  the  COBRA  supply  air  pressure  (see  chapter  3.5,

 5 – 6 bar).

* Check  settings  on  the  regulator  M:

pmin=3  bar  (oil),  4  bar  (grease)

• Fault: Pick-up arm (fig. 2, item C) does not move to initial position

Note: In such a case the pick-up arm will be put out of operation by its rated break point in order to avoid major damage.
After remedying the fault, repair the pick-up arm (see 3.5, fig. 5 + 6).

•

Cause

• YM valve (see fig. 2) does not switch back to initial

position:

•

Remedy

* Check  electrical  connection  between  SR  position  switch

and YM  valve.

* Replace  valve

• Fault: Carriage (see fig. 2, item F) does not move to initial position

•

Cause

• YR valve (see fig. 2) does not connect

• Throttle valve K is closed.

• Fault  in  the  compressed  air  supply  system.

•

Remedy

* Check  the  electrical  connections  and  operation  of  the YR

valve  (switching  phase  of  valve  indicated  by  LED)

* Open the throttle valve K and set the return speed.

* Check  the  compressed  air  lines.
* Check  the  inlet  air  pressure  required  (see  chapter  3.5,

 p = 5 – 6 bar)

• Fault: (for all valves) Valve does not operate although LED is lit

•

Cause

• Valve  inlet  voltage  too  low.
• Valve  defective

•

Remedy

* Check  the  wiring  diagram  and  the  line  routing
* Replace  the  valve.

• Fault: Carriage (see fig. 2, item F) moves too slowly or too quickly into initial position

•

Cause

• Adjustment for return travel too high or too low.
• COBRA inlet air pressure too low or too high.

•

Remedy

* Set the throttle valve M.
* Check  the  inlet  air  pressure.

All  the  repairs  which  are  beyond  the  knowledge  of  the  user’s
personnel  must  be  carried  out  by  LINCOLN  experts.

•

Cause

• Dampening  pressure  on  regulator  2  is  too  high.
• Spring  washer  kit  does  not  have  enough  initial  tension.

•

Remedy

* Reduce  dampening  pressure  to  less  than  0.5  bar.
* Check  tightening  torque.
