Revision 24 DOT Approved
7.3. Manifold Pressure
The manifold pressure system provides an analog display and a three place digital display. The
full sweep analog display resolution is 1" Hg. The digital display resolution is 0.1" Hg.
A warning alert activates when the manifold pressure redline is reached. The VM 1000 display
will flash, if installed, the EC100 displays the warning and an audible tone is heard.
7.4. Oil System
Oil temperature and oil pressure are displayed continuously on an analog and a digital display.
Oil Pressure: As oil pressure rises, the analog display increases proportionately. The digital
display reads in increments of 1 PSI. A warning alert activates whenever the oil pressure
redline is reached. The VM 1000 display will flash, if installed, the EC100 displays the warning
and an audible tone is heard.
Oil Temperature: As oil temperature rises, the analog display increases proportionately. The
digital display reads in increments of 1 degree Fahrenheit to a maximum of 300 degrees. A
warning alert activates whenever the oil temperature rises above the redline. The VM 1000
display will flash, if installed, the EC100 displays the warning and an audible tone is heard.
7.5. Fuel Pressure
Fuel Pressure: As fuel pressure rises, the analog display increases proportionately. The digital
display reads in increments of 1 PSI. A warning alert activates whenever the fuel pressure
redline is reached. The VM 1000 display will flash, if installed, the EC100 displays the warning
and an audible tone is heard.
7.6. Fuel Computer System
The fuel computer portion of the VM 1000 is not operational on the DA20-C1
7.7. Electrical System
Voltage is displayed both analog and digitally. Full color range marks provide a quick reference
for fast analysis of voltage levels. As voltage rises, the analog display increases proportionally.
The digital readout is at 0.1 volt resolution. A warning alert activates whenever the voltage
redline is reached. The VM 1000 display will flash, if installed, the EC100 displays the warning
and an audible tone is heard.
Amperage is displayed both analog and digitally. The load being monitored is the electrical
current the generator is supplying to the system. When the electrical load is increased by
turning on equipment, the ammeter will show an increase. When the load being supplied by the
generator drops below approximately 2 amps the VM 1000 display will flash, if installed, the
EC100 displays the warning and an audible tone is heard.
