061-325 SOS RAP
BSD-ON: 6.4
The light intensity of the LD2 does not reach the specified value.
Procedure
Check the connections of P/J401 on the MCU PWB and P/J140 on the ROS Unit. Connec-
tions are connected correctly.
Y N
Connect P/J401 and P/J140.
Check the wires between J401 and J140 for an open circuit or a short circuit (BSD 6.4 Flag 1/
Flag 2). The wires are conducting without an open circuit or a short circuit.
Y N
Repair the open circuit or short circuit.
Replace the ROS Unit (PL 3.1)
If the problem persists, replace the MCU PWB (PL 11.1).

061-333 ROS Fan defect RAP
BSD-ON: 6.5
ROS Fan rotation failure.
Initial Actions
Clean the fan.
Procedure
Execute Component Control[061-002 ROS FAN ON].Check for noise in the rotation of the ROS
Fan (PL 3.1). The ROS Fan is rotating.
Y N
Measure the voltage between the MCU PWB J401-A9 (+) and GND (-) (BSD 6.5 Flag 3).
The voltage is approx. +24VDC.
Y N
Replace the MCU PWB (PL 11.1).
Check the wire between J401 and J219 for an open circuit or a short circuit (BSD 6.5 Flag
3/Flag 4). The wire between J401 and J219 is conducting without an open circuit or
a short circuit.
Y N
Repair the open circuit or short circuit.
Replace the ROS Fan (PL 3.1).
Replace the MCU PWB (PL 11.1).
