CEBORA S.p.A.
♦ With Power Source off, temporarily disconnect the connectors J4, J5, J6 and J7
from solenoid valve board (2) and check the resistance on the terminals of the
solenoid valve coils. Correct value = approximately 12 ohm (27 ohm for V10 on
Console FPGC-2). If >Mohm (circuit interrupted), replace the solenoid valve
involved.
♦ Replace any defective solenoid valves, locating them with the aid of the table and
fig. 2.6.1.
♦ Check the wiring between the solenoid valves and the connectors J4, J5, J6 and J7 of solenoid
valve board (2).
♦ Check the wiring between J3 of solenoid valve board (2) and J7 of panel board (20).
♦ Make sure communication between Power Source and Gas Console, performing if necessary
the tests in par. 3.3.3..
♦ Check the Gas Console power supply, performing if necessary the TRANSFORMER (56)
POWER SUPPLY TEST and GAS CONSOLE POWER SUPPLY TEST in par. 3.3.1.
♦ With Power Source off, temporarily disconnect the connectors J4, J5, J6 and J7 from solenoid
valve board (2) and check the resistance on the terminals of the solenoid valve coils. Correct
value = approximately 12 ohm (27 ohm for V10 on Console FPGC-2). If 0 ohm, (short-
circuit) replace the defective solenoid valve and solenoid valve board (2).
♦ Replace the solenoid (2) and/or panel (20) boards.
