8. "SERVICE" mode
"SERVICE" mode can be used only when "SAFE" mode is enabled.
Use "SERVICE" mode to perform safe maintenance work with the RPB while within the
safety enclosure of the robot system. This mode can be selected by turning DI02 ("SERVICE"
mode input) OFF.

• Use "SYSTEM" mode to select the functions in "SERVICE" mode. (Refer to

8.1
Operation device
If operation from a device other than the RPB is permitted, the operator using the RPB may
be exposed to hazardous situations. For example:
1. When a dedicated input start signal is turned ON without the RPB operator
knowing about it.
2. When an external device runs a robot operation command through the RS-232C
interface without the RPB operator knowing about it.
To prevent this kind of accident in "SERVICE" mode, only the RPB can be used to operate
the robot and other operation devices are disabled. However, you may add other operation
devices provided you take responsibility for your own safety.
8.2
Prohibition of "AUTO" mode operation
A major purpose for robot operation while the operator is working within the safety
enclosure is maintenance and adjustment of the robot. If a robot program is executed
in "AUTO" mode during maintenance work, the robot might move on its own with no
warning to the operator. Therefore, "AUTO" mode operation is basically prohibited in
"SERVICE" mode. However, if robot movement in a program must be checked while the
operator stays within the safety enclosure, then "AUTO" mode can be selected provided
you take responsibility for your own safety.
8.3
Hold-to-Run function
If the robot operator using the RPB should trip or fall during maintenance work, he (she)
might be exposed to a dangerous situation. To prevent this kind of accident, the Hold-
to-Run function allows the robot to move only during the time that the RPB key is kept
pressed (like a deadman switch.). However, the Hold-to-Run function can be turned OFF
provided you take responsibility for your own safety.

software (VIP/WIN, etc.) that executes on-line commands through the
RS-232C interface cannot be used, except for cases where other operating
devices are enabled by on-line commands made via the RS-232C.
