HGM6100N Series Genset Controller User Manual                                                                      Page 13 of 47 
between  B+  and  the  charger  D+  (WL)  is  above  the  Failed  to  Charge 
voltage  difference  for  5s,  the  controller  shall  issue  “Failed  to  Charge” 
warning, while at the same time LCD displays “Failed to Charge” warning. 
When the battery voltage of genset is lower than threshold, controller will 
send warning alarm signal and it will be displayed in LCD. 
When the battery voltage of genset is higher than threshold, controller will 
send warning alarm signal and it will be displayed in LCD. 
When low coolant level input is active, controller will send warning alarm 
signal and it will be displayed in LCD. 
When sensor hasn’t connected to corresponding port, controller will send 
warning alarm signal and it will be displayed in LCD. 
When sensor hasn’t connected to corresponding port, controller will send 
warning alarm signal and it will be displayed in LCD. 
Maintenance  type  is  running  time.  When  genset  running  time  is  longer 
than maintenance time of user setting,  or the maintenance type is date, 
the current date  is  over the setting  date  and  the maintenance  action  is 
set  as  warning,  controller  sends  warning  alarm  signal  and  it  will  be 
displayed in LCD.   
When the water/cylinder temperature of genset is higher than threshold 
and Enabled High Temp. Stop Inhibit or Input High Temp. Stop Inhibit is 
active, controller will send warning alarm signal and it will be displayed in 
LCD. 
When the oil pressure of genset is less than threshold and Enabled Low 
Oil Pressure Stop Inhibit or Input Low Oil Pressure Stop Inhibit is active, 
controller will send warning alarm signal and it will be displayed in LCD. 
When  external  input  is  active,  controller  will  send  warning  alarm  signal 
and it will be displayed in LCD. 
When “Failed to Charge” input is active, controller will send warning alarm 
signal and it will be displayed in LCD. 
If  over  power detection is enabled, when the  controller detects that  the 
power value (power is positive) has exceeded the pre-set value and the 
action selects “Warn”, it will initiate a warning alarm. 
If  an  error  message  is  received  from  ECU  via  J1939,  it  will  initiate  a
