<<<< >>>> CANCEL SAVE
4. Press EDIT and using the <<<< and >>>> buttons, choose CURRENT and
enter the maximum current limit per phase using the rotary encoder.
5. Press ENTER to leave the menu, then either SAVE (to record the changes) or
CANCEL (to leave the previous settings unchanged).
To set-up priority channels:
It is possible to prioritise the channels which will reduce in intensity to ensure the
maximum demand is not exceeded when maximum current is selected above. This is
achieved by setting the dimmer channel to “priority”, and it will then ignore any
instruction to reduce level if the maximum demand is exceeded.
1. Select CONFIG. from the home menu
2. The screen shows the individual channel number (or ALL if the dimmer set-up
scheme is all together) with a list of all available channel characteristics
including PRIOR (priority) which is to the right of the screen, and is accessible
when >>>> is pressed repeatedly:
CONFIGURE CHANNEL PARAMETERS
CH MAX% T-IN T-OUT CURVE I/O PRIOR PHASE
ALL 100 00.05 00.05 LIN NO [NO] OFF
<<<< >>>> CANCEL SAVE
3. Use the <<<< and >>>> buttons, choose PRIOR [enabled when square
brackets are shown] and set it to either NO for normal operation, or YES if the
dimmer has to maintain its level if the maximum current is exceeded. If set to
No, the dimmer will take part in a general lowing of intensity if the preset
maximum current (maximum demand) for the phase in this dimmer device is
exceeded. If set to Yes, the dimmer will remain at its level, and others will
reduce in level to maintain a maximum phase current.
4. Using the UP and DOWN buttons to address other channel numbers (unless all
dimmers are being set-up together).
5. Press ENTER to leave the menu, then either SAVE (to record the changes) or
CANCEL (to leave the previous settings unchanged).
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.
