F10 Security module's (4 A) inlet fuse
1.5 THE MACHINE DOES NOT RE-START: POSSIBLE CAUSES.
Once the microswitches of the finger-safety fillet or the "shut down emergency"
button intervene, the procedure described in 1.2 is carried out. The machine does not
continue to function normally because it is necessary to identify the problem through
the signals of the security module located in the left side of the machine (from its rear
view, as described in the manual for installation and use).
Follow all the above manual instructions, open the "left side closure door" and
indentify the module on the next image.
The A1/A2 green led shows that there is power supply voltage in the module.
•
The K1 and K2 green leds indicate the proper functioning of the corresponding
•
channel components.
If the A1/A2 led is turned off when the machine is powered, replace the F10 fuse.
If the K1 or K2 leds are turned off when the machine is powered, replace the
microswitch of the finger-safety fillet or the "shut down emergency" button contact
that does not function.
After recovering the functions of the machine, close "the left side closure door" once
again.
