3.3.3 - Power source powered, display and signals does not indicate the correct values.

CAN-BUS COMMUNICATION TEST.
Upon start-up all leds and displays on (lamp-test) on the operator panels of both the Power
Source and Gas Console. After one second, Power Source display (B) reads "954" and
display (C) shows the software version installed (e.g., r1). Simultaneously, on Gas Console,
display (F) reads "Art" and display (M) indicates "477" (start-up).
♦ Check the wiring between connector J18 of control board (38), connector (3) on
Power Source, connector (16) on Gas Console and J6 on panel board (20).
♦ Check the supply voltages of the control (38) and panel (20) boards, performing if
necessary the CONTROL BOARD (38) POWER SUPPLY TEST, GAS
CONSOLE POWER SUPPLY TEST, PANEL BOARD (20) POWER SUPPLY
TEST in par. 3.3.1.
♦ Check on J6 of panel board (20), terminals 1(+) and 2(-) voltage = +8 Vdc (CAN
bus line power supply). If incorrect, with Power Source off disconnect J18 from
control board (38). Power up again and make sure, with J18 disconnected, that
voltage = +8 Vdc on J6 of panel board (20) terminals 1(+) and 2(-). If correct,
replace control board (38). If incorrect, replace panel board (20).
♦ Make sure that the correct programs are entered in the control (38) and panel (20)
boards, performing if necessary the programming procedure available on the
Cebora Web site (see par. 2.3).
♦ Replace the control (38) and/or panel (20) boards.

When turned on, after the start-up phase, the keys on the operator panels of the Power Source
and Gas Console allow all of the steps involved in selecting the "Job" and "Mode" as
described in par. 3.2.3, and in the Instruction Manual of the Plasma PROF 164 HQC.
♦ Check the supply voltages of the control (38) and panel (20) boards, performing if
necessary the CONTROL BOARD (38) POWER SUPPLY TEST, GAS
CONSOLE POWER SUPPLY TEST, PANEL BOARD (20) POWER SUPPLY
TEST in par. 3.3.1.
♦ Replace the control (38) and panel (20) boards.
