Emergency Response Actions
Response Actions to Interference or Crash
In the event of interference or crash with a robot or a jig attached to the
robot (e.g. gun and transformer, etc.), be sure to take the inspection and
response actions described in Chart 6. A significant force is applied to ATC
upon interference or crash, which may create any factor that shorten the
product service life. Therefore, the inspection interval may need to be
shortened as necessary. For ATC replacement and damaged part
replacement, please refer to relevant sections of this document and the
"Maintenance Procedures."

Response Action to Water Exposure
If the equipment is exposed with water, immediately stop using it and check
if water enters into the product. Using the equipment with water presenting
in internal electric component may cause signal output failure due to short-
circuit. Moreover, when grease is washed out by water, sliding parts will be
subject to higher friction, which can result in poor coupling or sealing.
In the event of exposure to water, be sure to conduct the inspection and
actions specified in Chart 7.

Check item Check method Action
1
Electric contact and
proximity SW signal
Check for short-circuit on the I/O
unit side. Visually check for
malfunction of the chuck/unchuck
sensor and LED ASSY, and ensure
there is no water infiltration.
If any, wipe off with a dry
cloth. (*Do not attempt to
blow water off with an air gun
or the like as doing so may let
water get further into the
equipment.)

Cam, lock parts and
tapered pin
Visual check Apply grease
3 O-ring Visual check Apply grease
4
Other section exposed
with water Check all sections for water
accumulation and wipe off if any. Apply grease to uncoated
metal parts.
