3.1.7 Electrofusion process:
WARNING !
In order to guarantee a good electrofusion, it is recommendable not to
reuse a fitting in which the fusion cycle has been interrupted.
Ú
The unit has initiated the electrofusion cycle. The time and countdown till you get to zero
will come on the display in seconds. The START/VALIDATE led will flash during the whole
cycle.

The input voltage is checked during the start up phase of the electrofusion cycle. During
this phase it is considered that the unit – specially for a generator – will stabilize its
energy supply. The unit verifies if the input voltage and electrofusion current are within
the established range (voltage: 165-265 V for 230Vac or 90-140 V for 110 Vac; current
>2A <70A). Once overpassed this initial phase, the above mentioned voltage and current
values are continuously checked during the whole electrofusion cycle.
If electrofusion data were entered using a barcode (BEAT-2 only), the unit should also
check that the fitting resistance corresponds to that of the fitting connected and that it is
within the tolerances assigned by the manufacturer. This will be done when the unit starts
the electrofusion cycle.
If the resistance is not correct, the display will show the following messages, where
appropriate:
FAILURE OF FITTING
RESISTENCE TOO HIGH
When the fitting resistance read by the unit is higher
than allowed.
FAILURE OF FITTING
RESISTENCE TOO LOW
When the fitting resistance read by the unit is lower
than allowed.
Check the fitting, connections, etc., and restart the cycle.
When the fusion cycle has ended satisfactorily, the display will show the following
message:
BEAT-XX 23ºC

displayed alternately.
