This calibration has to be performed using the Feeder, either LF-52D or LF-56D, connected to the machine.
1.
Prepare the external reference ammeter (A) and voltmeter (V). Connect a load to output with A and V.
2.
Enter to Service Mode: on the feeder, push the right button (LF 52D) or right encoder (LF 56D) and switch
machine on. Release button after end starting.
3.
General information: left encoder is used for switch output on/off (clockwise: on, counter-clockwise: off)
4.
There are 3 service modes (selected by right encoder and accepted by pushing right button /right encoder/):
a)
Selecting test modes (tESt)
b)
Voltmeter calibration (CAL U)
c)
Ammeter calibration (CAL I)
5.
tESt: you can select test mode numbers below:
a)
200 (CC)
201 (CV)
b)
c)
202 (CP)
d)
212
6.
CAL U: you can follow procedure:
a)
Left display shows rEF <-> oFF
b)
Switch the output on: display shows rEF <-> on
c)
Set reference voltage to ca. 25,0V/200A on external meter by turning right encoder and adjusting load
d)
Confirm the setting by pushing the right button (right encoder) – machine is switching off
e)
Switch the output on: display shows SEt <-> on
f)
Set voltmeter value (on right display) to ca. 25,0V by turning right encoder. WARNING: be sure that the setting
value is the same as the external reference voltmeter value.
g)
Confirm the setting value by pushing the right button (right encoder) – machine is switching off
h)
After that machine goes into the service modes selection (point 4)
7.
CAL I: you can follow procedure:
a)
Left display shows rEF <-> oFF
b)
Switch the output on: display shows rEF <-> on
c)
Set reference current to ca. 25,0V/200A on external meter by turning right encoder and adjusting load
d)
Confirm the setting by pushing the right button (right encoder) – machine is switching off
e)
Switch the output on: display shows SEt <-> on
Set ammeter value (on right display) to ca. 200A by turning right encoder. WARNING: be sure that the setting
f)
value is the same as the external reference ammeter value
g)
Confirm the setting value by pushing the right button (right encoder) – machine is switching off
h)
After that machine goes into the service modes selection (point 4)
Exit from Service Mode: switch machine off.
