3-(4)Checking of Purging Error Detection Operations
Turn OFF the power supply to the DX200 after above checking
operations are completed.
4. After
completing
all the checking operations mentioned in 3-(1), (2),
(3) and (4), turn OFF the power supply to the DX200 and set the
adjusting pressure for purging pressure reducing valve and operating
pressure reducing valve to be within each range shown in
“List of Setting Value for Purging Air and Operation Air Reducing
Valves”
.
Table 10.3.1.2 “Operation Method of Pressure Reducing
for the pressure reducing valve operation.
5. Re-install the cover with the hexagon socket head cap screws. (Refer
Fig. 10-10 “Pressure Switch Unit Cover”
.)

Turn ON the power supply to the DX200.
Purging start and a message “Air Purging” is indicated on the
programing pendant window. While purging, confirm that no power is
supplied to motors and manipulator is inoperable.

After one minute, set 0 MPa to the purging pressure of pressure
switch unit.
The mode is changed to abnormal pressure mode (purging error)
and a message “AIR PURGE ERROR” is indicated on the
programing pendant window. Confirm that an alarm lamp on the
DX200 lights.
While abnormal purging pressure error alarm is occurred, confirm
that the power supply is not turned ON and the manipulator is
inoperable even [SERVO ON READY] on the programming pendant
is pressed and the enable switch is gripped.
