♦ Check the wiring between connectors J3 of board (62) and terminals S1, S2, S4
and S5 of board (68), and between J1 on board (68), fixed fitting (50) and torch
adapter.
♦ Check the jumpers on the patch torch adapter, according to table above.
♦ Check power supply board (68); see "Torch board power supply test" par. 3.3.4.
♦ Replace board (68).
♦ Replace board (62).

button released.
♦ Make sure there is no short-circuit in the wiring between the terminals of J4 on
board (62), S6 and S7 on board (68), J2 on board (68), the fixed fitting (50), the
torch cable and button.
♦ Replace the torch start button.
♦ Replace board (68).
♦ Replace board (62).
♦ Replace board (62).
E53 - Start button pressed while resetting from stop due to pressure or temperature
beyond allowable limits.
The "low gas pressure " and "high temperature" alarms will stop the power source, lighting
the corresponding signal (see Instruction Manual), but do not remain in memory. They are
automatically reset when the pressure and temperature return to within the allowed limits. On
automated systems, the system may be reset when the start command has not yet been removed,
since before the stop occurred. To prevent the power source from starting suddenly due to such a
random reset, this situation is detected and causes a saved block of the power source, indicating
error E53.
