OK
key.
MODE OF USE
1 MANUAL FUSION
Validate it by pressing the
OK
key.
Electrofusion voltage in a range of 8 and 44 V are only accepted.
FUSION VOLTAGE:
U = 40,0 [V]
U = 40.0 V corresponds to the last entry; entry via the
keyboard the desired voltage, if different.
Validate with the
OK
key to continue or press
STOP
to go back to the previous screen.
FUSION TIME:
Tf = 400s Ta=ttºC
tf = 400s corresponds to the last entry; entry via the
keyboard the desired time, if different.
Ta = tt
̊
C corresponds to the ambient temperature (for information) for correcting the
electrofusion time based on this merger.
Validate with the
OK
key to continue or press
STOP
to go back to the previous screen.
COOLING TIME:
tc = 11 [min]
tc = 11 corresponds to the last entry; entry via keyboard the
desired cooling time, if different
.
Validate with the
OK
key to continue or press
STOP
to go back to the previous screen.
NOTES!
If no fitting is connected to the unit’s electrofusion cable terminals,
the display will show the following message “NO FITTING: CHECK
WIRES!”. Refer to clause 3.1.6.4 of this
Manual
.
U=40,0V tf=400s
tc =11min START
The display shows the input parameters and the message
START making intermittences.
Press
START

FUSION
.
U=40,0V I=aaA
tf =400 R=rrΩ
The display shows the electrofusion voltage, current and
time as well as the fitting resistance.
During the electrofusion cycle the
FUSION
LED blinks and the buzzer becomes audible.
Once terminated the fusion cycle, the display shows the cooling time entered:
COOLING:
tc = 11 [min]
Where tc = 11:00 is the entered time. Automatically starts the
countdown to the expiration of the time
.
