3.5 - Commissioning
- Choose a dry and dust-free area.
- Attach the Tractelec to the tractor’s three-
point linkage (mobile version) or check that
it is correctly secured to its support (fixed
version).
- Position the universal joint and check the
alignment. Connect the tractor’s power
take-off shaft to the universal joint.
- Connect the cable coming from the supply
reversing switch (position “0”) to the Tract-
elec.
- Put the power take-off shaft into rotation,
adjusting the speed until a frequency of
52 Hz is shown on the display (between 420
and 430 rpm). If necessary, select frequen
-
cy display by repeatedly pressing the
MODE
button until the “Hz” indicator is lit.
- Applying a load: move the reversing switch
to the “backup” position.
- Start a motor and check its direction of ro-
tation. If necessary, swap two phase wires
on the Tractelec side of the reversing switch
to obtain the opposite direction of rotation.
- Start up the various motors in descending
order of power, then the other devices to be
powered, monitoring the voltage read-out
on the voltmeter.
- If necessary, adjust the speed again until
50 Hz / 400 V is shown on the display.
- It is essential to disconnect the load (posi-
tion “0” on the reversing switch) before stop-
ping the Tractelec. Stop the tractor engine.
3.6 - Use
3.6.1 - Display panel
The Tractelec display panel allows you to
check the machine’s different electrical
values.
Press the
MODE
button repeatedly to scroll
the main display between the following
values (the indicator corresponding to the
selected unit will light up): U - Voltage in
Volts (V) > A - Current in Amps (A) > Hz -
Frequency in Hertz (Hz) > VA - Apparent
power in Volt-amperes (kVA) > HOUR -
Running time in hours (H).
At start-up, the display is automatically set
to display U - Voltage in Volts.
3.6.1.1 - Automatic mode
It is possible to scroll through the different
measurements automatically. Once the
unit is turned on, press and hold (> 3 sec)
the
MODE
button. The individual measured
values are displayed successively at
3-second intervals. Briefly press the
MODE
button to stop scrolling and return to manual
mode.
