Shortcircuit in tank.
Disconnect CN6 connector
from the power board.
If the tank is shortcircuited, the
system will turn on. Reconnect CN6
and release the wires from the tank
terminal strip.
Check wiring, some
cables might be bypassed.
Change tank.
Shortcircuit in
manifold.
Disconnect CN6 connector
from the power board
If the distributor is shortcircuited,
the system will turn on. Reconnect
CN6 and release the wires from the
manifold terminal strip.
Check wiring, some
cables might be bypassed,
broken...
Change heating elements
of the distributor
Hose-applicator
shorcircuit (1-6
output).

connectors one by one
until the unit turns on.
Later, it will have to be found out if
the shortcircuit is in the hose or in
the applicator.
Change hose or
applicator.
Equipment shortcircuit malfunction
Causes Checking Comments Actions
Equipment power
supply malfunction.
Check voltage between
phases and neutrals.
Check voltage in CN4
connector (power board).
Voltages will vary depending on
power supply.
Check wiring. Check
electrical net. Change
electric supply cable.
Ribbon cable
malfunction.
Check ribbon cable
(CN11).
Check the connections between the
cable and the board.
Change ribbon cable.
Tank fuse blown.
Check fuse continuity
(F01).
Release the fuse to check it out with
the system turned off.
Change fuse.
Power board
damaged.
Check CN6 connector
voltage (pins 2 and 4).
Correct if voltage is around 230V and
DL2 is on.
Check wiring, it might be
wrong positioned.
Change board.
Power supply wire to
the tank damaged.
Check CN6 connector
voltage (pins 2 and 4) and
in the tank terminal strip.
If connector voltage is around 230V
and the cercamic terminal strip does
not, the wire is damaged.
Check connections to the
connector and terminal
strip. Change wire.
Heating element
shortcircuited or
blown.
Check voltage in the
terminal strip.
Correct if voltage equals to 230V. Change tank.
