7.2.2 Setup > MODULES
The Setup > Modules menu is where the parameters for individual modules can be adjusted. The functions
here enable "fine-tuning" of the module output.
7.2.2.1 AC INPUT VOLTAGE CALIBRATION
Use this function if it becomes necessary to recalibrate the voltage readings of any of the UPS's input
phases. Note that this does not refer to the input reading of a particular module but rather to the input of all
modules together.
To perform the calibration, for each input phase use a voltmeter to measure between the phase and
midpoint. Enter the measured values into this screen and press "confirm". Calibration of the input ac
voltage reading should be performed only under conditions where the input and output voltages are stable
and not subject to fluctuation.
7.2.2.2 AC OUTPUT VOLTAGE CALIBRATION
Use this function if it becomes necessary to recalibrate the voltage readings of any of the UPS's output
phases. Note that this does not refer to the output reading of a particular module but rather to the output of
all modules together.
To perform the calibration, for each output phase use a voltmeter to measure between the phase and
midpoint. Enter the measured values into this screen and press "confirm". Calibration should be performed
only under conditions where the input and output voltages are stable and not subject to fluctuation.
7.2.2.3 MODULES INPUT CURRENT CALIBRATION
Use this function if it necessary to recalibrate the current (ampere) readings of any of the UPS's input
phases. This calibration should be performed on each module, one module at a time, until all modules have
been calibrated. (The value you enter is sent to all modules, so input current calibration must be performed
on one module at a time, with all of the other modules turned off.) To turn modules OFF, see section
7.3.1.3 "Operation > Switch on/off > MODULES OFF".
To perform the calibration, measure the current on the input phase with an ammeter, then enter the
measured value into this screen and press "confirm". Only the values that you modified (indicated by a
change in colour of the numbers from white to orange) are sent to the module.
For your reference, the present UPS-measured values are displayed on the right side of the screen.
Calibration should be performed only under conditions where the input and output current are stable and
not subject to fluctuation.
