Maretron ACM100 User Manual

 

reconnecting the current transformer, you may change the value of this parameter from the 
default value of “Normal Install” to “Inverse Install” to correct for this. 
 
2.5.5.5  Current Transformer B 

If you notice that the current of phase B is negative when it should be positive, or vice-versa, 
then the current transformer has been installed backwards. If this happens, then instead of 
reconnecting the current transformer, you may change the value of this parameter from the 
default value of “Normal Install” to “Inverse Install” to correct for this. 
 
2.5.5.6  Current Transformer C 

If you notice that the current of phase C is negative when it should be positive, or vice-versa, 
then the current transformer has been installed backwards. If this happens, then instead of 
reconnecting the current transformer, you may change the value of this parameter from the 
default value of “Normal Install” to “Inverse Install” to correct for this. 
 

The ACM100 is capable of transmitting many different kinds of NMEA 2000

®

 messages (or 

PGNs) associated with AC power sources. You may individually enable or disable each of 
these messages. You may also change the rate of transmission of each of these messages if 
desired. 
 

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

The ACM100 outputs a variety of information about the AC power source onto the NMEA 2000 
network. The tables below detail which measurements are made available on the bus for the 
different combinations of different AC source types and circuit types which may be selected.
