Start Button Produces No Effect; Some Signals From H Connector Do Not Work - Cebora SYNSTAR 200 M Manual De Servicio

□ Fan (44) starts working.
YES Correct?
♦ Check wiring between J7 power board (45)
and J1 panel board (48).
♦ Check supply voltages of the power (45) and
panel (48) boards, performing the tests of par.
3.3.1.
ERROR CODE TEST.
□ Upon turning the unit on, after the start-up phase, an
error condition is displayed: a code appears on the dis-
play A to identify the error type.
NO Correct?
♦ See Error codes, par. 3.4.
COMMANDS AND SIGNALS TEST.
□ After the start-up phase, with knob B it possible to per-
form all of the steps involved in selecting a "Process",
"Mode" and "Programs", as described in the Instruc-
tions Manual.
YES Correct?
♦ Check the supply voltages of power (45) and
panel (48) boards, performing, if necessary,
the tests of par. 3.3.1.
♦ Make sure that the correct program is
inserted in the panel board (48), performing,
if necessary, the "Firmware Upgrade"
procedure (see par. 2.4).
■ Check wiring between J7 power board (45) and J1
panel board (48).
■ Replace the power (45) and/or panel (48) boards.
3.3.4

Start button produces no effect.

NOTE
The start command may be given to the power source either
through the central adapters C or via the connector H.
The two circuits are parallel connected inside the panel
board (48), so only one of the two signals is enough to start
the power source.
START COMMAND TEST.
□ Panel board (48), terminal J6-A(+) and J6-B(-) = 0 Vdc
with start button pressed, +9 Vdc approximately, with
button released (with button connected to the central
adapters C).

□ Panel board (48), connector J3, terminals 3(+) and 4(-) =
0 Vdc with start button pressed, +9 Vdc approximately,
with button released (with button connected to the
connector H).
YES Correct?
♦ Check the wiring between J6, panel board
(48), central adapter C and torch button.
♦ Check the wiring between J3, panel board
(48) and connector H.
♦ Check the supply voltages of the panel board
(48), performing, if necessary, the PANEL
BOARD (48) POWER SUPPLY TEST, of
par. 3.3.1.
♦ Replace panel board (48).
■ Check integrity of the components inserted on the start
line between J6 and Q1 on the panel board (48) (see
connectors map, par. 5.5).
■ Replace panel board (48).
