006-372
Status Indicator RAPs
Initial Issue
006-372 Start of Scan Error RAP
During or after warm-up, the Start of Scan (SOS) signal is longer than specified.
Procedure
Switch off the power. Remove the IOT Top Cover Assembly (REP 14.4). Remove the Control-
ler Chassis (REP 1.11). Switch on the power. Cheat the Top Cover Interlock. Approxi-
4 VDC is measured between J 14-11 and J14-10 on the MCU PWB.
Y
N
Go to Flag 1 and check the wire for a short circuit to ground. If the wire is good, replace
the MCU PWB (PL 11.2).
+24 VDC is measured between J 14-13 and J14-10 on the MCU PWB.
Y
N
Replace the MCU PWB (PL 11.2).
Switch off the power. Remove the ROS Cover. Disconnect J 123 from the ROS. Measure the
resistance between the following plug/jack pins:
•
P/J 14-11 on the MCU PWB to J123-3
•
P/J14-13 on the MCU PWB to J123-1
•
P/J14-12 on the MCU PWB to J123-2
•
P/J14-10 on the MCU PWB to J123-4
All the measurements are less than 1.0 Ohm.
Y
N
Go to Flag 1 and Flag 2. Check the wires for an open circuit.
Reconnect J 123. Switch on the power. +5 VDC is measured at J 125-1 on the ROS.
Y
N
Go to the 001-705 ROS +5 VDC Switched Voltage RAP.
Switch off the power. Disconnect J 121 from the ROS. Measure the resistance between the fol-
lowing plug/jack pins:
•
J 14-5 on the MCU PWB to J121-3
•
J14-4 on the MCU PWB to J121-4
•
J14-7 on the MCU PWB to J121-1
All measurements are less than 1.0 Ohm.
Y
N
Go to Flag 3 and check the wires for an open or short circuit.
Replace the ROS (PL 5.1). If the problem continues, replace the MCU PWB (PL 11.2).
