Fault Indicators
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.
Error
LED
Fault
Indicated
Meaning
Solution
1
Power supply
failure during
weld
The power supply was
off at sometime during
the weld
•
Check and repair power supply
•
Check plug connection
•
Check cables are not damaged or
broken
•
Re-weld fitting only after it is allowed
to cool to ambient temperature
2
Stop button
pressed
during weld
Stop button was
pressed
•
Re-weld fitting only after it is allowed
to cool to ambient temperature
3
Power supply
out of limits
Supply frequency not
between 40 and 70
Hz, or Voltage not
between 194 & 264V
•
Check and rectify generator output
•
Check mains supply
•
Make sure supply is to required
specification
4
Ambient
temperature
out of range
Temperature of the
EF1 is not between
-15° C (5º F) and
+45° C (113º F)
•
Allow EF1 and fitting to cool in the
shade
•
Wait for ambient temperature to return
to range
5
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
•
Move generator closer and use shorter
extension cord
•
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
•
Check extension leads being used are
to specification
7
High output
current
Regulation error in
electronics
•
Switch off machine and switch on
again after 10 seconds.
•
Ensure welder is within temperature
range
•
If problem persists, return EF1 to
supplier
The EF1 can be reset after a fault has been remedied by pressing and holding
the START / STOP button for 3 seconds.
