Excess Current; Emergency Off; Heater Coil Error; Power Supply Failure At Last Welding - HURNER HST 300 Print 315 2.0 Manual De Instrucciones

11.2.7 Excess Current

The output current value is in excess; possible causes: short-
circuit in the heater coil or the welding cable. During the
start stage the upper abort threshold equals 1.18 times the
value at start, in any other case the upper limit depends
on the load value and is calculated as the current at start
plus 15%.

11.2.8 Emergency Off

The welding process has been interrupted by pressing the
STOP/RESET key.

11.2.9 Heater Coil Error

The dynamic current value during welding differs by more
than 15% from the required value, indicating a short-circuit
in the heater coil.

11.2.10 Power Supply Failure at Last Welding

The last welding is incomplete. The welding unit was dis-
connected from the power supply voltage while it was
in progress. To go on using the unit, this error has to be
acknowledged by pressing the STOP/RESET key (see also
Sect. 9.4).
