11.2.3 Resistance Error
The resistance value of the connected fitting is out of the read toler-
ance.
11.2.4 Frequency Error
T h e f r e q u e n c y o f t h e i n p u t v o l t a g e i s o u t o f t o l e r a n c e
(42 Hz - 69 Hz).
11.2.5 Voltage Error
Check generator voltage and current. The output voltage does not
correspond to the value previously read; the welding unit has to be
sent to the manufacturer for check-up.
11.2.6 Low Current
The message is displayed if the there is a momentary current failure or
if the current decreases by more than 15% per second for 3 seconds.
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 disconnected 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).
