Meter Calibration
When running in Manual Mode, the control allows meter
calibration process to be invoked, when the Genset
Running (Ready to Load) state is reached. The Meter
Calibration process is invoked by holding the Reset and
OK buttons pressed for 5 seconds continuously. The
process allows the arrow keys to be used for adjusting
the displayed alternator AC Voltage / Current values to
actual values (as measured using an independent
calibrated instrument) one by one.
The Meter Calibration Process is available when running

the genset in Manual Mode only.
Nominal Voltage and Frequency
The PS0500 does not have the control of the genset

frequency (speed) and the genset voltage.
The nominal voltage and the nominal frequency set-up

parameters are used only for calculation of the over
voltage, under voltage, over frequency and under
frequency fault thresholds and determining if the Genset

All the inputs are active GND. And outputs are low side drivers. Remote E-Stop switch should have two independent
potential free contacts. One NC contact for cutting out the Battery supply to the Fuel Solenoid and another NC contact
to disconnect controller’s E-Stop input from GND to indicate to the control when the E-Stop is pushed in active state.
Battery Positive is not provided on the Customer terminal block (TB2). External provision needs to be made in the
harness to provide fused B+ via a 1 amp fuse for wiring up external relays. External Relays of suitable contact ratings
must be used for controlling FSO, Starter, Customer Output and Glow plug.
PC Tool Connector
The PC tool connector is a dedicated 5 pin connector header block. The possible supplier is Tyco, with the supplier
part numbers are 796643-5. The Cummins part number for the same is 0323-2191-04.

SECTION 6 – SETUP AND CALIBRATION

Read Safety Precautions, and carefully observe all of the instructions and precautions in this manual.
CAUTION Only qualified technicians should adjust the parameters described in this section. Failure
to follow this may affect genset operation and may cause damage to the genset or to equipment connected to
the genset.
In this section, italics are used to identify a specific parameter by name.
Parameters
See Section 4 for more information about parameters that you can adjust in the Operator Panel.
Capture File
Use InPower to save the current settings in a capture file on a PC or network. You can use the capture file to look at
the current settings while you are away from the PS0500 or to restore settings if you have to reset the PS0500 for any
reason. See the InPower User Guide for more information.
While InPower can be used with the PS0500 for facilitating the setup, it is not essential for carrying out the basic setup
operations. The basic setup can be performed directly from the control panel of PS0500. Following paragraphs
Describe the process of carrying out basic setup from the control panel.
Entering and leaving the Setup Mode
The Setup mode can be entered only from Stop mode when the genset is not running. This is accomplished by
holding the Reset and the OK buttons pressed for 5 seconds continuously while in stop mode. The RED Stop Led
flashes faster (double the normal rate) as long as the control is in setup mode. Pressing ← button while in Main Menu
exits the setup mode. Navigation through the setup menus is described further in a separate section later.

If after establishing and correcting any fault on the rectifier assembly the output is still low when separately excited,
then the main rotor, exciter stator and exciter rotor winding resistances should be checked (see Resistance Charts),
as the fault must be in one of these windings. The exciter stator resistance is measured across leads F1 and F2.
The exciter rotor is connected to six studs, which also carry the diode lead terminals. The main rotor winding is
connected across the two rectifier plates. The respective leads must be disconnected before taking the readings.
Resistance values should be within 10% of the values given in the table below
