switch (9) and terminal IN2 of filter board (36). Replace the choke (17) if
necessary.
♦
Check the mains voltage conditions.
MAINS VOLTAGE RECOGNITION TEST.
q
Power board (35), ter (+) and - (-) of the rectifier bridge W1 = approxi320
Vdc, with both mains voltages (115 Vac or 230 Vac), 3 seconds after closing the switch (9),
thus after the mains voltage selection phase.
NO
YES
♦
Power board power supply (35) normal.
PANEL BOARD (31) POWER SUPPLY TEST.
q
Panel board (31), connector J1, terminals 2 (+) and 14 (-) = +5 Vdc, terminals 4 (+) and 14 (-)
= +14 Vdc; all 3 seconds after closing the switch (9), thus after the mains voltage selection
phase.
YES
NO
♦
Check the wiring between J1 power board (35) and J1 panel board (31).
♦
With the power source off, disconnect the connector J1 from the panel board (31)
and check the resistance between terminals 2 and 14 and between terminals 4 and
14 of J1 on panel board (31). If you find short-circuits, also disconnect CN2 from
the panel board (31) and repeat the test. If the short-circuit is still present, replace
the panel (31) and power (35) boards; if the short-circuit is removed, check the
wiring between CN2 on panel board (31) and J1 on HF board (22), and replace the
HF (22) and power (35) boards if necessary.
♦
Replace the power board (35).
♦
Check the supply voltage (also see Alarm signals, par. 3.4).
♦
Replace the panel (31) and/or power (35) boards.
