Points to Check during Line Downtime (or Line Uptime)
●Recommended usage
During the robot downtime, e.g. nighttime or holidays, keep the tool side
module detached.
During uptime, check that the cam is closed at the time of approaching for
coupling of the tool side unit. Coupling operations performed with cam left
opened may cause crash between the cam and lock parts, resulting in
component damage.
Fig. 20. Precautions for Line Downtime
●Usage not recommended (only allowed if there is an absolute necessity)
If the tool side adaptor cannot be kept detached during downtime due to any
reasons related to the facilities, take due care of the following.
If the line has to be stopped with the tool side module coupled, be sure to
release the unchuck port regardless of air supply pressure presence.
(No residual pressure allowed.)
If the unchuck port is not released, the cam may be operated due to air
wraparound resulting in tool side module falling. Position the tool
appropriately to prevent falling and turn the power and air supply OFF before
stopping the equipment.
There may be residual air pressure when: (see

)
●air supply is shut off by bending/twisting of the unchuck tube or excessive
tightening of the banding bands: or
●the exhaust ports of the manifold and solenoid valve are plugged.
Points to check before restarting the line:
●Ensure there is no gap between the coupling planes.
