Operating Instructions
28
Deactivate
Monitor Mode will be deactivated and system will begin
HVAC operation if the operator presses the On/Off button at
the HMI, moves the Mode selector or moves the Fan Speed
selector. The selected HVAC mode will activate. The STBY
indicator on the HMI will turn off. System will continue to
monitor battery voltage and engine coolant temperature.
Operation
While Monitor Mode is active the APU will continue to start
and stop as necessary to maintain battery voltage and engine
coolant temperature (if the Arctic Option is installed). While in
Monitor Mode the system will not react to changes in cab
temperature. TriPac Cool, Heat and Fan modes will remain off.
Battery voltage sensing is enabled. When battery voltage falls
to the level set by Battery Voltage Restart Value (default 12.2
Vdc) the APU engine will start so it can charge batteries. It will
continue to run until the Charge Current Shutoff Value setting
has been reached (default 12 amps).
If the Arctic Option is installed and enabled, truck engine
coolant temperature sensing will occur. If engine coolant
temperature at WT2 falls below 35 F the APU engine will start
to warm the truck engine. It will continue to run until returning
coolant temperature rises to 55 F.
Monitor Mode may be disabled. If disabled the system will
return to the mode it was in when the truck ignition was turned
on.
NOTE: This is not the recommended setting. Refer to the
TriPac EVOLUTION Diagnostic Manual TK 55739 Section
3, Software Settings, Switch to Monitor for more information.
Engine Load Management
To maintain Tier 4 engine emission levels, engine load may be
reduced under some conditions.
