Sheet 5.2
Phenomena of fault Cause Solution
The AOPD does not work, all the
indicators are off
No supply voltage Couple in correct power supply
The power fuse blowing out
Replace the power fuse with a new one
of the same specification, 5×20/1A
Power cable fault or bad contact
for socket connector
Check and repair power cable and
socket connector
Power switch broken or bad contact for
connector, or relevant circuits broken
Replace the key switch, or check and
repair connector and relevant circuit
The switch mode power is broken
Check the connection of circuit and
socket connector, replace the switch
mode power if the wiring is correct
The conversion of indicator is
normal, press is not able to wok
The fuse F1 fusing
Replace the power fuse with a new one
of the same specification, 5×20/5A
The circuit between OSSD breaks.
Check and repair the circui t and wiring
of OSSD
The contact point of relay is ageing or
broken
Replace the relay with the same
specification one
Electric fault of machine
Check and repair the circui t and wiring
of OSSD, if the wiring is correct, please
check and repair the electric circuit of
machine
Turn the function switch to the the
controller non-protection side, press
is not able to work
For CPSII, function switch is
broken or related circuit fault
Check the circuit of function switch, if
there is no fault, replace the controller
For CQ2, function switch or relay
fault, the load fuse blowing out

The green status
indicator of
receiver is on
S signal line of transmission cable
loose contact
Check the connection for S signal line
The relay fault
Replace the relay with the same
specification one
The controller fault
Replace the controller with the same
specification one
The red detection indicator is on Contact adhesion for one relay
Replace the two relays with the same
specification ones
All the phenomenon shown in the above sheet takes place when the power switch is turned on.
