SAVES AND TRANSFERS
Changes made to the Power Grid Controller via MSDView are in real time. You can create and save
numerous different les to your PC and load them back into the unit for different applications.
The following will go through a general description of the software for the Power Grid Power Module
PN 7764 Controller.
OPERATION
The 7764 Power Grid Power Module is a fully programmable 4-channel solid state relay. The use of
the Power Module eliminates the need for electromechanical relays and fuses. Any of the four outputs
can be congured as a digital output (i.e ON/OFF) or can be congured as a Pulse Width Modulated
output (i.e. PWM) with user-programmable frequencies up to 10 Kilohertz. The solid state switches
are protected from over-current and over-temperature conditions and can handle currents up to 20
Amperes. The user has the ability to program a lower current limit.
To control the output signals, the user can select any of the four input wires or the signal from an
external temperature sensor. Moreover, the Power Module can be used in conjunction with the Power
Grid (PN7730) to expand its programmable options. For instance, when connected to the Power
Grid, the outputs can be controlled by the launch wire signal or as a function of engine speed (RPM).
All the programmable features are congured using the MSDView software provided.
The Power Module has two modes of operation:
Note: The Power Module self detects the mode of operation by the way it is connected in the circuit.
When the CAN bus is functional, it will operate in POWER GRID MODE. Otherwise it will operate in
STAND ALONE mode.
STAND ALONE
The user can control any of the four outputs independently using any of the four input wires or the
temperature reading from an external temperature sensor. Also, the selected input wire can be used
to trigger a time counter, like a launch wire, and control the time of activation as well as the duration
of the output. The state of the inputs and outputs can be observed in the monitor window in real time.
POWER GRID MODE
The Power module is connected to the Power Grid (PN7730) via the CAN connector.
In Power Grid mode, the Power Module retains all the features available in Stand Alone mode and
expands the control and programmable features. In addition to the four input wires, the user can
select the “launch wire” signal from the Power Grid as the activation source. Also, the output control
can be enabled/disabled based on the engine speed (RPM) reading from the Power Grid.
In addition to providing expanded control over the outputs, Power Grid Mode utilizes the Power Grid
data recorder.
Another extra feature the Power Grid adds to the Power Module is the ability to control ignition timing
retard as a function of “Time From Activation”. Time from activation is the time elapsed since the
activation of the selected input wire. A 2-D plot of “timing retard vs time from activation” is provided
for this feature.
Note: For more information on the features and settings, please refer to the “SETTINGS” section below.

DATA ACQUISITION
OUTPUT SETTINGS
These settings give the user control on the behavior of the output. Each one of the four outputs has
an “OUTPUT SETTINGS” sub-tab and is congured individually.
