DC 3535/2240/1632, WC M24
OF 1-3
Initial issue
Status Indicator RAPs
OF 1-3 +24 VDC Enable
Use this RAP to determine why the +24V LVPS is not enabled.
Procedure
The machine is a DC 3535.
YN
Refer to Figure 1. +3.3 VDC is measured between P/J505-3 (+) on the 24V LVPS and
GND (-).
YN
+3.3 VDC is measured between P/J534-B4 (+) on the I/F PWB and GND.
YN
Go to Flag 1. Repair the open circuit.
Replace the MCU PWB (PL 13.1).
If the problem continues, replace the ESS PWB (PL 13.1).
+5 VDC is measured between P/J505-4 (+) on the 24V LVPS and GND (-).
YN
+5 VDC is measured between P/J511-3 (+) on the 5V LVPS and GND (-).
YN
Replace the 5V LVPS (PL 9.1).
Go to Flag 2. Repair the open circuit between the 24V LVPS and 5V LVPS.
Switch off the power. Less than 5 ohms is measured between P/J505-2 on the 24V
LVPS and GND.
YN
Go to Flag 3. Repair the open circuit between the 24V LVPS and 5V LVPS.
Replace the 24V LVPS (PL 9.1).
Refer to Figure 2. +5 VDC is measured between P/J505-3 on the 24V LVPS and GND (-).
YN
Go to Flag 4. Check the wire for an open circuit. If the wire is good, replace the MCU PWB
(PL 13.1).
+5 VDC is measured between P/J505-4 (+) and P/J505-2 (-).
YN
Go to Flag 5 and Flag 6. Check the wires for an open circuit. If the wires are good, replace
the MCU PWB (PL 13.1).
Replace the 24V Low Voltage Power Supply (PL 9.1).
