INTRODUCTION 

 

The IGC700 is a highly configurable, compact, panel 
mounted module designed for the control and protection of 
diesel and spark ignited engines.  This integrated speed 
control system is a high performance multi-functional 
isochronous digital speed control.  The governor function can 
be used for wide range variable speed (Pumps, Hydraulic 
system, Sweepers, etc.) applications or constant speed 
Generator Sets.  The front panel keypad allows direct settings 
and security without need of a laptop or special software.  
Customized firmware can also be downloaded into the flash 
memory with a laptop or via a Down Load Module (DLM) 
available from GAC.  Integrated “Start”  and “Stop” buttons 
provide manual control and shutdown supervision with 
additional security.  The monitoring and protection capability 
of the IGC700 includes inputs for up to 10 sensors, all of 
which are setup through the front panel keypad.  Oil 
Pressure, Engine Coolant Temperature and Charge Level are 
dedicated standard inputs, which can be configured for either 
digital or analog inputs.  The additional inputs can be 
configured to accept signals (switch-type, analog, active high 
or active low) through GAC’s Smart

View

  software.  With 

this greater flexibility, conditions like Low Air Pressure, Low 
Oil Level, Low Coolant Level and Door Open can be 
configured and monitored with the proper sensory devices.  
All faults and failures are indicated by bright, multi-colored 
LED’s located on the front Annunciator Panel. The IGC700 

is designed to take the appropriate action, which is to warn 
the operator of the faulty/failed condition and to shutdown 
the system if the condition is potentially damaging and/or 
dangerous.  These actions are taken based on parameters set 
at the time of installation.  The IGC700 Series has three 
normally open 20 Amp relays with outputs that are common 
to battery voltage.  These are provided for Crank 
Termination, Fuel Solenoid (shut down signal) and Glow 
Plug Preheating. 

 

DESCRIPTION 

 

Engine speed functions are easily set up through the keypad.  
The use of an external potentiometer for trim or wide speed 
range setting can also be configured with the keypad.  The 
general-purpose inputs can also be configured to switch 
between fixed speed settings.  The internal actuator driver 
circuit can deliver enough power to drive most proportional 
actuators with a current rating of up to 10 Amps.  If levels are 
expected to exceed 10 amps or you are unsure of the actuator 
compatibility, contact GAC application engineering or a 
qualified GAC representative. 

The IGC700 provides a simple 2-button control for operation 
under normal conditions.  Depressing the STOP button will 
shut down the engine immediately by cutting the engine’s 
fuel supply and turning the actuator power off (if it is in use).  
Depressing the START button will begin the crank cycle.  
Once the engine is started, the control will govern the engine 
and provide protection according to the parameters that were 
set during installation.
