Enable
Each resistive/current loop measurement tool can be enabled or disabled. If this box is checked, the
tank level corresponding to this channel will be shown. If this box is unchecked, no tank level will be
shown. As shipped from the factory, tank level channels are disabled.
The following sections describe in detail the configuration of the current loop measurement channel
when it is enabled.
Label
Type a description of the tank being monitored in the field marked Label. Maretron display products
will display this label text when you are selecting data to display. If the channel is disabled, no
further configuration is required.
Pressure
Pressure at 4mA (Current Loop channel only)
Program this parameter to match the pressure reading of the current loop pressure transducer when
it is sourcing a current of 4mA. You can determine this value by examining the specification of the
pressure transducer being used.
Pressure at 20mA (Current Loop channel only)
Program this parameter to match the pressure reading of the current loop pressure transducer when
it is sourcing a current of 20mA. You can determine this value by examining the specification of the
pressure transducer being used.
Tank Capacity
In addition to indicating the fluid level within a tank, the channel also can be configured or
programmed with the attached tank's capacity. This way, you will be able to view the tank's capacity
as well as the amount of liquid remaining anywhere on the vessel where there is an NMEA 2000 ®
compatible display.
Tank Number
Use this parameter to set the tank number for the tank level channel being configured.
The channel supports up to sixteen potential tank numbers (0 through 15) for a given type of tank.
Tank Type
This parameter allows you to set the fluid type in the tank for identification by display devices. You
can configure the channel for any of these tank types:
• Fuel
• Fresh Water
• Waste Water
• Live Well
• Oil
• Black Water
• Reserved-1 through Reserved-7 (if none of the above types apply)
