Is there AC 100V behind

the fuses F1 and F2?

Fuses F1 and F2 have blown

out. Replace the fuses. If they

blow out again, the POWER

unit is out of order

Are there M+14V output at
Pin 1 and M+7V output at
Pin 3 of the PM connector?

Is there +5V output at Pin 2

of IC9504 (MAIN module)?

Failure in the PWR module

Is there an output of +5V

at Pin 5 of the LD connector,

Pin 4 of the PW connector

and pin 5 of the RS

connector?

Failure in +5V line. Check the LED,

PWR and RS232C modules

Failure in the

MAIN module

Try to disconnect the PW, PQ,

and RS connectors from one

after another. If the outputs of

M+14V and M+7V are found
available, the circuits beyond

these connectors are out of
order. If no outputs are found,
the POWER unit is out of order.

In the case of green and red flashing, the power supply
cannot be reset with the OFF/ON operation at the mains
power supply, remote control, and wall outlet.

For the alarm reset, keep pressing the input changeover key
of the main unit and move the mains power supply to the
"ON" position at the main unit. While doing so, it is
necessary to keep pressing the input changeover key of the
main unit for more than two seconds.In the case of green
and red flashing, the power supply cannot be reset with the
OFF/ON operation at the mains power supply, remote
control, and wall outlet.
