Instructions for Safe Use
s-4
ON/OFF enabling is done by operating a Mot button on the teach pendant. When
pressing this button, the servomotor is enabled, and disabled when releasing it.
To ensure the safe use of the teach pendant, the following rules must be observed:
Ensure that the enable button works at all times.
Disconnect the enabling timely when temporarily stopping the robot, programming or testing.
When entering the robot working space, the demonstrator shall bring the teach pendant to
avoid other people operating the robot without the programmer is informed.
The teach pendant must not be placed within the working space of the robot to prevent
abnormal actions in case of collision between the robot and the teach pendant.
Maintenance personnel:
(1) Pay attention to the parts in the robot that are prone to become hot
Some parts of the robot in normal operation will become hot, especially the servomotor and
reducer, which may cause burns when being approached or touched. When it is inevitable, protective
equipment such as heat-resistant gloves should be worn.
Before touching these parts with your hands, try to feel the temperature of these
parts by approaching with your hand, in case you are scalded.
Wait for enough time after machine halt, so that the hot parts can be cooled
down, and then you can carry out the maintenance work.
(2) Safety precautions on removing parts
Ensure that the internal parts such as the gears are no longer rotating, and then you can open the
lid or the protection device. You shall not open the protection device when the gears and bearings are
rotating. If necessary, use the auxiliary device to make the internal unfixed parts remains its original
position.
The initial test upon repair, installation and maintenance shall be carried out by following the steps
below:
a) Clean up the robot and all maintenance and installation tools in the working space of the robot.
b) Install all the protective measures.
c) Ensure that people are standing outside the safe range of the robot.
d) Pay special attention to the working conditions of the parts repaired during testing.
In case of robot repair, do not use the robot as a ladder, and do not climb on the robot to avoid
falling
(3) Safety precautions on pneumatic/hydraulic components
After turning off the air source or hydraulic pump, a few residual gas or liquid exists in the
pneumatic system or hydraulic system. Beware these gases or liquid, which have a certain energy; we
must take some measures to prevent the residual energy from damaging to the human body and
equipment. Therefore, it is necessary to release the residual energy in the system before maintaining
the pneumatic or hydraulic components.
Mount a safety valve to avoid accidents.
(4) The power supply need be opened in many cases of fault diagnosis, but it must be shut when the
maintenance or repair is carried, moreover, you should cut off other power supply connections.
