DSM250 User’s Manual

6.12.4.2.1Sensor

You may select whether this channel is connected to a “3-phase” sensor (Maretron fuel flow sensors with three pulse outputs), or a “1-phase” sensor (other manufacturer’s fluid flow sensors with a single pulse output).

6.12.4.2.2Engine Instance

Program this parameter to match the desired engine instance number of the flow rate and total fuel used for this channel. You can program this parameter to any value between 0 and 252.

NOTE: If the operating mode is set to “Differential Flow Rate”, then this parameter is unavailable for Channel #0.

6.12.4.2.3Engine Label

Each channel has a text label you can set to identify the load controlled by that channel (for example, “PORT ENGINE” or “COOLING WATER FLOW”). For each channel, set this to a value which describes the flow being monitored so that you can easily identify it in display devices.

6.12.4.2.4K-Factor

Program this parameter to match the K-factor that appears on the flow sensor connected to this channel.

6.12.4.2.5Data Damping Period

You can configure a damping parameter to smooth the flow rate readings or make them more responsive. The data damping is configurable between 0.2-25.0 seconds. The default data damping period is 3.0 seconds.

6.12.4.2.6Reset Total Volume Recorded

The FFM100 maintains the total volume recorded in EEPROM, so that it is maintained across power cycles. Select this menu entry to reset the total volume recorded to zero.

6.12.4.2.7Temperature Instance

Program this parameter to match the desired instance number of the temperature reading for this channel. You can program this parameter to any value between 0 and 252. The default value for this parameter is 0.

6.12.4.2.8Temperature Source

Program this parameter to match the desired source type of the temperature reading for this channel. The default value for this parameter is 129 (User Defined).

6.12.4.2.9Temperature Label

Program this parameter with a text string which identifies the particular temperature parameter being monitored by this channel. Maretron display products will display this label text when you are selecting data to display.
