2.3.1 Introduction

 Objective

 The maintenance switch allows only the limited operations to be performed with safety covers open,

thus improving the work efficiency during maintenance.

 General Description

 The machine is provided with a maintenance switch (key switch); one on the front. This switch is used to

release the safety circuits.

 Turning ON the front maintenance switch disables the safety circuits of the transfer rail cover and front

cover.

 When the maintenance switch is turned ON, each axis teaching and operations via the sub-control

panel are partly permissible.

 Maintenance mode should be used only when recovering from any troubles which occurred on the

machines. As a rule, only the experienced maintenance engineer who have sufficient knowledge of the

machine are allowed to operate the equipment in this mode.
