Operation Manual

Feature Summary
The PowerTech PCM controls all of the start and run processes and characteristics of any PowerTech
generator. The features of the application are:
Internal Ambient Temperature Sensor
Provides an on-board temperature sensor.
Oil Pressure Sensor / Switch Input
Allows input from an external oil pressure sensor or switch. Will shut down the generator if
sufficient pressure is not detected after a start-up period.
Coolant Sensor / Switch Input
Allows input from an external coolant temperature sensor or switch. Will shut down the generator if
extreme temperature is detected.
Auxiliary (Generic) Shutdown Switch Input
Allows input from any external active low (ground) switch. An active state of this switch will shut
down the generator immediately.
DC Power Supply Voltage Measurement
Measures the voltage level of the DC power supply. The DC voltage is monitored for a minimum
and will shutdown the Generator if it falls below a threshold (configuration parameter). This is also reported
on the PCM.
AC Output Voltage Measurement
Measures the voltage level of the AC output. This information is monitored to detect limit
conditions. It also is reported on the PCM. Over and Under Voltage conditions are reported.
AC Output Current Measurement
Measures the current level of the AC output. The data is reported on the PCM and is used for
current, wattage, and load measurement.
AC Output Frequency Measurement
Measures the frequency level of the AC output. This info is monitored to detect a valid start as well
as limit conditions. It also is reported on the PCM. Over and Under Frequency conditions are reported.
Warm Start
Adjusts the Pre-Heat glow plug activation time according to the coolant temperature.
One-Touch Remote Start Trigger
In addition to control via PCM, the unit will respond to an active high digital input. The unit can be
configured to either start or stop in response to activation of a momentary switch or a toggle switch.
Blink Code Fault Reporting
Simple diagnostic data is available through blink codes on a dedicated active high output. The PCM
state as well as fault codes are displayed.
Event Recording
A portion of non-volatile memory is dedicated to recording diagnostic and other events. If a clock is
available on the network, the time and date of the event is included. Events include diagnostic messages,
starts, stops, and configuration changes. Total event capacity is roughly 2,000 events.
Load Profiling
The unit records the total amount of time the generator spends in each of several load intervals.
The information is recorded each time the generator stops, showing the usage profile for that specific cycle.
AGS
Automatic Generator Starting for low battery voltage. Programmable at the factory
voltage threshold and run time. Unit can sense genset battery voltage or any other battery voltage as
required. Enabled or disabled by an external switch.
Ignition Sensing
Will shutdown genset or prevents genset from starting if DC voltage is applied from any
external source. (Example: vehicle ignition, shore power sensor, or transfer switch, etc…)
