Resettable PTO Interrupts [Does Not Require System to be Turned Off and On Again]
The command signal for the vehicle to run PTO mode and engage the generator passes through all
three of these checks in series. Removing any one of them in will shut of the generator system. If
the truck is running, it will immediately restart the generator once the interrupt is restored.
1.
PTO Upfitter Switch
2.
Real Power Emergency Stop Button
3.
Generator Over-Temperature Switch
Note: The order in which these signals are engaged or disengaged does not affect operation. For example, if the
Over Temperature Switch shuts the PTO off but the PTO dash switch remains engaged with the engine on,
the generator system will automatically come back on (whether intentional or not) once the temperature
switch resets. The same is true for the Emergency Stop, but it should be noted: Real Power recommends
always using the PTO upfitter switch to operate the generator rather than the emergency stop.
Stationary Elevated Idle Control (SEIC) program interrupts
[Requires System to be Turned Off and On Again]
In addition to the PTO enable command signal, there are a number of fault conditions that will cause the
truck shut down the PTO and high idle internally. Once they occur, the command signal must be cycled
by switching the PTO switch off and on again. Fault conditions include:
1.
Pressing the foot brake pedal
2.
Shifting out of Park
3.
Releasing the Parking Brake
4.
Pressing the accelerator pedal
5.
Vehicle rolling / motion
6.
Over temperature of the engine or transmission coolant
REAL POWER Secure Truck Feature
All Real Power generators installed on Ford and Dodge trucks come equipped with the Real Power
Secure Truck feature, which allows the PTO, once engaged, to continue to run even after the ignition
key is turned off and removed. At any time that the generator is running, the operator may remove
the key from the truck and lock the doors behind him, allowing him to work on power equipment
hundreds of feet away without concern for the security of the vehicle.
PTO operation will continue unless and until any one of the above interrupts is engaged or a fault
condition occurs. At that time, the vehicle will shut down completely, including the engine and be
inoperable until the key is put into the ignition and turned back to start up. Alternatively, an
operator can put the key back in the ignition while the generator is still running and return it to the
RUN position. Then the truck will not shut down when the PTO is turned off.
Periodic Cycling
The Real Power generator system should be started and ran for 10 minutes once every 30 days if not
used regularly. This will cycle the shaft and bearings and keep them lubricated.
