Four-digit, seven-segment LED display. This displays the selected parameter from the list
alongside. Use the button to select which parameter is to be displayed, as indicated by the
adjacent LEDs. The
button selects the parameter in sequence, as follows. Note that line
voltage readings are prefixed by ‘L’ while phase-neutral readings are prefixed by ‘n’.
• Alternator voltage L1-L2, prefix L
• Alternator voltage L1-N, prefix n
• Alternator voltage L2-L3, prefix L
• Alternator voltage L2-N, prefix n
• Alternator voltage L3-L1, prefix L
• Alternator voltage L3-N, prefix n
• Alternator frequency (Hz)
• Alternator L1 current (A)
• Alternator L2 current (A)
• Alternator L3 current (A)
• Alternator power output (VA) into load. This is the sum of voltage (L/N) x current for all
phases.
• Alternator RPM, as measured by alternator frequency or magnetic pick-up as selected by
Speed Sensing Input Selection (P16)
• Battery Voltage (VBAT)
• Engine running time in hours-since last reset via Engine Running Time Reset (P35). This is
a six-digit number. The first three (high) digits are shown in the first display - prefixed H- and
the second (low) in the second display - prefixed L.
• Oil pressure
• Temperature
• Fuel level
• The alarm LED will flash continually if the unit detects any fault. When the display select
button is pressed so as to select this option, the display will show the cause of the fault
indication. If more than one error condition is present, repeated pressing of the button will
show each in turn. Possible error messages are:
EStP - Emergency Stop
bAT1 - Low Battery Voltage
bAT2 - Weak Battery Alarm
bAT3 - High Battery Voltage Alarm
ocr
- Over Current Failure
Serv
- Routine maintenance due
LOPr - Low Oil Pressure
HItE
- High Coolant Temperature Alarm
LoFL - Low Fuel Level Alarm
