UPP® ELECTROFUSION WELDER: F A U L T I N D I C A T O R S
When an error has occurred during the weld cycle that will have an effect on the
success of the joint, the red warning LED on the right side of the display will light up.
Also one of the “weld progress” lights will light up at the same time to show what type
of fault has occurred.
NOTE: UPP Welders should be returned for factory inspection every 3 years.
ERROR LED
FAULT INDICATED
MEANING
SOLUTION
1
Power supply failure
during weld
The power supply was off at
sometime during the weld
• Check and rectify power supply
• Check plug connection
• Re-weld fitting only after it is allowed to
cool to ambient temperature (1 hour)
2
Stop button pressed
during weld
--
Re-weld fitting only after it is allowed to cool
to ambient temperature (1 hour)
3
Power supply
out of limits
Supply frequency not
between 45 and 65 Hz,
or voltage not between
194 and 264V
4
Ambient
temperature out
of range
Temperature of the
EF1 is not between
-15° C and +45° C
No output current
(open circuit)
• Loose connection to
terminal pin
• Loose contact in the
welding circuit
• Faulty fitting
• Start button not
depressed for long enough
• Make sure connectors are pushed
firmly on to terminal pins
• Check welding cable connection
and continuity
• Replace fitting
• See operating sequence, step 5
6
Low output current
• Resistance value of
fitting is too high
• Too many fittings
connected in series
(primary mode only)
• Input voltage too low
• Use only UPP® electrofusion fittings
and correct welding cable
• Check resistance codes on fittings;
do not exceed a sum total of 10
• Check supply voltage
7
High output current
Regulation error
in electronics
5
• Check and rectify generator output
• Check mains supply
• Allow EF1 and fitting to cool in the shade
• Wait for ambient temperature to return to
range (1 hour)
Switch off machine and switch on again
after 10 seconds; if problem persists,
return EF1 to supplier
The EF1 can be reset after fault has been rectified by pressing and holding Start/Stop button for 3 seconds.
Generators with an Eco Throttle or Automatic Throttling Feature should have this feature turned off to
eliminate unnecessary errors that may present during the weld process.
