Getting Started
How to install
General
To ensure proper function:
Wiring for binary inputs and analog inputs must not be run with power cables.
Analog and binary inputs should use shielded cables, especially when length >3m.
Power supply
To ensure proper function:
Use min. power supply cable of 1.5mm
2
Maximum continuous DC power supply voltage is 36VDC. Maximum allowable power supply voltage
is 39VDC. The InteliLite’s power supply terminals are protected against large pulse power
disturbances. When there is a potential risk of the controller being subjected to conditions outside its
capabilities, an outside protection devise should be used.
Hint
:
The InteliLite controller should be grounded properly in order to protect against lighting strikes!!
The maximum allowable current through the controller’s negative terminal is 4A (this is dependent on
binary output load).
For the connections with 12VDC power supply, the InteliLite
NT
includes internal capacitors that allow
the controller to continue operation during cranking if the battery voltage dip occurs. If the voltage
before dip is 10V, after 100ms the voltage recovers to 7 V, the controller continues operating. During
this voltage dip the controller screen backlight can turn off and on but the controller keeps operating.
It is possible to further support the controller by connecting the external capacitor and separating
diode:
The capacitor size depends on required time. It shall be approximately thousands of microFarads.
The capacitor size should be
5 000 microFarad to withstand 150ms voltage dip under following conditions:
Voltage before dip is 12V, after 150ms the voltage recovers to min. allowed voltage, i.e. 8V.
Hint
:
Before the battery is discharged the message "Low BackupBatt" appears.
