GENERAL RULES FOR MAINTENANCE

Before carrying out any maintenance operation, carefully read chapter 1 Safety

Specifications and in particular the instructions in the paragraph concerning

maintenance.

Any maintenance operation on the controller may only be carried out by specialised and

suitably trained personnel.

If the control panel is opened and then closed, make sure that the control and/or

extension spindle of the main switch Q100 is in the same position (ON/OFF) to prevent

damage to the control itself.

The removal or installation of components of the electromechanical section, electronic

modules, connectors, cables and any other component may only be carried out with the

main switch open.

Before doing any maintenance work whatsoever make sure that there are no external

current supplies interlinked to electronic modules and components of the controller.

The electronic modules are sensitive to electrostatic discharge: handle the

modules only after wearing an antistatic bracelet connected to ground. The

modules should be touched only holding them by their fastening screws.

· All tripped protection fuses must be replaced only by equivalent ones specified by the

manufacturer. The use of unspecified fuses may cause danger for the operators and

faulty controller operation.

· In the event of cable replacement, restore the connections of any screens disconnected

previously.

· The replaced cable must bear the COMAU code corresponding to the removed one.

· Before connecting any cable, always refer to the controller wiring diagrams.

When installing new cables avoid bending radii differing from the previous ones. Use the

same previous fastening points and specific routes.

If the cable has a cable clamp check that it is in correct operating conditions.

After any maintenance operation, re-install any protections removed previously.

After any maintenance work, before restoring the normal working cycle, carry out the

controller functional tests, particularly on the replaced component.

If the controller is partly or completely disposed of, the parts to be disposed of must be

differentiated. At all events disposal of the controller must meet the laws in force of the

country in which the controller is installed.
