To switch on current limitation:
1.
Select INSTALL from the home menu
2.
Press DOWN or UP or use the rotary encoder to choose GENERAL SETTINGS
menu. Press SELECT.
3.
Press DOWN or UP or use the rotary encoder to choose CURRENT
LIMITATION menu. Press SELECT.
4.
The screen shows:
GENERAL SETTINGS
CURRENT LIMITATION: [OFF]
5.
Press EDIT and using the encoder wheel, choose ON or OFF to enable or
disable the current limitation.
6.
Press either SAVE (to record the changes) or CANCEL (to leave the previous
settings unchanged).
Voltage regulation and limitation
Voltage regulation is a software feature which maintains the dimmed level of
channels in the event of the mains supply fluctuating (e.g. when power is supplied
from a generator source or a high-impedance main). The dimmer's incoming voltage
is measured, and if it diverts from the anticipated incoming voltage, the dimmer will
adjust the output accordingly to maintain a constant voltage at the output.
This feature does not maintain the voltage of full-on dimmer channels, as the
regulation circuit can only work with sufficient voltage headroom. Programming
involves two stages, firstly checking the factory-set installation option which
calibrates the incoming mains voltage, and secondly activating the voltage regulation
software.
Voltage limitation is a feature which limits the maximum voltage reaching the lamp.
This allows a global ceiling level to be set to improve lamp life at the expense of
colour temperature at maximum output.
To check line voltage calibration
Note: this setting is made during final testing at the factory and does not usually require any
adjustment.
1.
Select INSTALL from the home menu.
2.
Press DOWN or UP or use the rotary encoder to choose LINE VOLTAGE
CALIBRATION.
3.
Press SELECT, and the screen displays:.

If the voltages shown are different from the line voltages measured at the
dimmer supply input socket, press EDIT and >>> or <<<< to select the line to
calibrate, shown by square brackets. Calibration is done manually, by
measuring the incoming main supply voltages and then calibrating the software-
