This message appears in the following cases:
1. Fitting not connected.
2. Disconnection of the electrofusion terminals.
3. Cut in the filament of the fitting resistance.
4. If the electrofusion current is lower than 2 A.
4.2.5 Electrofusion output voltage:
If there is a deviation of ± 0,5 V in the output voltage during the electrofusion of the
fitting, the cycle will stop and the display will show:
VOLTAGE FAILURE
xxxxs
Where xxxxs corresponds to the remaining
cycle time at the moment of stopping.
This message may also appear due to poor fitting application (fitting voltage outside
range).
4.2.6 Protection against internal temperature:
If the electrofusion unit is submitted to intensive, prolonged operation, especially with
large-diameter fittings with high fusion times, for which the internal temperature may
exceed the maximum allowed, the following procedure is established:
1.
If after an electrofusion cycle the transformer temperature is higher than 60ºC,
the transformer and electronics are protected by an internal temperature sensor
which blocks the unit. If this safety device is activated, the electrofusion under
way will not be interrupted. The display will show the following message:
TRAFO TEMPERATURE
TOO HIGH **WAIT**
This message will remain on the screen until
the internal temperature falls to 55ºC.
2.
If during an electrofusion process the transformer temperature reaches 90ºC, the
cycle will stop and the unit will remain blocked until the internal temperature falls
to 55ºC. The display will show the following message:
TEMPERATURE TOO HIGH
xxxxs
Where xxxxs corresponds to the remaining
cycle time at the moment of stopping.
