5.2
CHANNEL MODES
Eight channel modes are selectable for easy
configuration, omitting unwanted options.
WARNING
In a 24V system, modes Light 12V and
Switched Light 12V will change to 24V in
Manual Override Always On (section 3.2).
5.2.1 Conventional
The conventional mode is used only for switching
the channel On/Off. See section 5.3 for channel
mode options. In Conventional mode the output
voltage equals the input voltage, there is no PWM on
this channel.
Application: navigation Electronics, refrigerator.
5.2.2 Light
12V
The Light 12V is convenient for 12V lighting without
built in switch. A correction for short voltage dips has
been built in. At a voltage supply of 24V, the Light
12V mode is still possible. The light intensity can be
adjusted by MasterBus configuration. Fade modes:
•
dimming,
•
fading out,
•
fading in and out.
Manual Override overrides the Light 12 V setting,
see section 3.2.
Application: navigation lights and ceiling lights.
5.2.3 Light
24V
See light 12V, now for 24V lighting. At a voltage
supply of 12V, the Light 24V mode is not convenient.
5.2.4
Switched light 12V
The Switched light 12V is convenient for 12V lighting
with a built in switch. The option Minimum Current is
omitted to prevent an unwanted alarm at switch off.
With a voltage supply of 24V, the Switch light 12V
mode is still possible.
Application: reading light with built in switch.
5.2.5
Switched light 24V
See Switched light 12V, now for 24V lighting. At a
voltage supply of 12V, the Switched light 24V mode
is not convenient.
5.2.6 Motor
This function features an optional 1 second ramping
up setting.
Application: cooling fan or toilet pump.
5.2.7
Bilge pump float
Function for bilge pump with floating switch. The
bilge pump includes a float switch enabling the pump
when soaked, with option Always On.
