3.3.3 Emergency Stop Activated
If this message appears in the display, one or more emergency stops have been activated
and the machine has been switched off.
Find out why the emergency stop has been activated and correct the problem. When all
hazards have been eliminated that activated the emergency stop, the emergency stop can
be reset. Reset the Emergency Stop Button by turning it and then pulling it outward.
When all emergency stops have been reset, the security circuit can be reset by pressing the
green OK button
OK
in the display.
If the Green OK button
OK
can not be reset even though all emergency stops are reset, it
may be due to a short circuit to ground in the emergency stop circuit or pilot signal circuit.
The emergency stop circuit and pilot signal are fed by fuse F4. If the fuse needs to be
replaced, replace the defective fuse with a 5 * 20mm, 50mAF (fast fuse).
