5.7.3 SYSTEM VOLTAGE

The system ECU and display voltage can be checked on the
Electrical Diagnostics screen and is a good indicator of truck
voltage regulation and loose or bad main power
connections.

Voltage below 9V will cause electronic devices to shutdown
and/or go into a fault condition.

Another good indicator of the Commanders set voltage is
shown on the Mixer Settings and Maintenance screen. The
Commander can be set for either 12V or 24V systems. If the
voltage setting does not show the correct voltage for the
system press the default curves set button and see if it
changes.

If it does not change, reboot the Commander display by
pressing the E-Stop and waiting 3-4 seconds and restart. Go
back to the Mixer Settings and Maintenance screen and
check the voltage setting again.

If it still reads the incorrect voltage call Proall as this may
indicate the system has been reset in the Factory Settings
and needs to be re-configured.

If the Commander system is set for the wrong voltage the
control valves will not function properly. Mixer functions
will be either really fast or really slow (may not run at all).
