2.5.1.8 Restore Factory Defaults

Selecting this configuration option causes all stored parameters in the ACM100 to be reset to
the values they contained when the unit was manufactured.

2.5.2 AC Circuit Type

You must configure the ACM100 as to what type of AC circuit connection it is monitoring. The
allowable values for this parameter are as follows:
 Single-Phase (Phase A) – use this value when power is connected via a single hot wire
and a single neutral wire (a typical 110VAC connection in the US).
 Single-Phase (Phase A, B) – use this value when power is connected via the two hot
wires and single neutral wire from a single phase of a transducer (a typical 220VAC
connection in the US).
 Three-Phase (Phase A, B, C) – use this value when power is connected via the three
hot wires and single neutral wire from a three-phase "Wye" or "Delta" connected circuit.

2.5.3 AC Device Type

You must configure the ACM100 as to what type of AC source it is monitoring. The allowable
values for this parameter are as follows:
 "Generator" (default) – use this value when you are monitoring the output of a genset.
 "Utility" – use this value when you are monitoring shore power
 "Bus" – use this value if you are monitoring power flowing across a cable that is not
located directly at the output of a genset or a shore power connection (e.g., an AC
selection switch might have as an input the shore power and another input from the
genset, connecting the ACM100 at the output of the AC selection switch would require
the ACM100 to be configured as "Bus".

2.5.4 Device Instance

®
NMEA 2000 provides a unique AC power instance for each AC power source on a vessel. This
value should be programmed in each ACM100 so that each ACM100 is associated with a unique
device instance number. The default instance number is 0, which is used to indicate the first
ACM100 that is hooked to the network. Subsequent ACM100s connected to the network would
be numbered 1, 2, and so on.

2.5.5 Label

Program this parameter with a text string which identifies this device. Maretron display
products will display this label text when you are selecting data to display.

2.5.6 Reset Total Energy Recorded

The ACM100 accumulates the total energy imported from a Utility and exported from a
generator. Select this option to zero the total energy accumulated readings in the ACM100.
