INSTALLATION

The electrical connections for the IGC700 are illustrated in

Diagram 1 on the previous page.

configuration using Terminals R and S, please see Table 1

below. Actuator and Battery connections to Terminals A, B,

C, D and E should be #14 AWG (18mm) or larger. Long

cables require an increased wire size to minimize voltage

drops. Battery positive (+) inputs at Terminals A and C

should be fused for 15 Amps as illustrated. The Magnetic

Speed Sensor connections to terminals L and M must be

twisted and/or shielded for their entire length. If shielding is

used on the magnetic sensor, then it should be connected to

Terminal B. This is to prevent unwanted signals from being

introduced into the IGC700 causing erratic operation of the

unit.

Terminal Identification & Connectivity

Accessory Wiring

The cables to the Variable Speed Potentiometer can be of any

length up to 5m (15ft). A shielded cable is required for

lengths over 5m. Connect the shield to Terminal B and to

Case Ground as shown in Diagram 1.

Magnetic Pickup

With the engine stopped, adjust the gap between the

magnetic speed pick-up and a ring gear tooth.

should not be any smaller than 0.45 mm (0.020 in.). Please

follow the manufacturer's instructions when installing the

Magnetic Pickup. Verify proper installation by measuring

the AC voltage output of the pickup while cranking the

engine.

This output must be greater than 0.5Vac, while

cranking. Connect the Magnetic Pickup to Terminals L & M.

Battery

The battery can be either 12 or 24 volts. Connect the positive

cable to Terminals A and C (+) and the negative cable to

Terminal B (-).

Actuator

Connect the actuator wires to Terminals D & E. The IGC700

can deliver up to 10 Amps for actuator operation. Check the

actuator literature for more information.

Fuel Solenoid

Connect the Fuel Solenoid to Terminal F. The second wire

of the Fuel Solenoid is connected the negative (-) of the

Battery.

Variable Speed Potentiometer

Although a 2k-10k pot is acceptable, it is recommended that

a 5k pot be used for the Variable Speed pot. Terminals I, J &

K are used to connect the Variable Speed pot. Connect the

wiper terminal of the pot to Terminal I. Use Terminals J & K

for the other two connections to the pot.

Preheat

Terminal G supplies battery voltage to the Preheat Solenoid

with the second wire connected to the negative (-) of the

Battery.

Crank Solenoid

Terminal H supplies battery voltage to the Crank Solenoid.

Connect the other end to the negative (-) of the Battery.

Remote START/STOP

Connect the negative (-) of your Remote Start/Stop switch to

Terminal N. The other side of your Remote Switch is tied to

Battery positive (+).

Alarm Output

Terminal O can sink up to 500mA for use as an audio or

visual annunciator.

This output is configured to activate

when Engine Temperature or Oil Pressure exceeds the

parameter previously set by the user. The Alarm Output can

also be configured to work with any or all of the configured

inputs.

Engine Temperature & Oil Pressure

Terminals P & Q are dedicated inputs. These two inputs

require switch type sensors.

Temperature Sensor to Terminal P and the Oil Pressure

Sensor to Terminal Q. The second wire from each of these

sensors is connected to Battery ground (B-).

User Configurable Inputs

•

Terminals R & S can be configured as either

independent, general-purpose inputs or as a pair of

inputs for Fixed Speed Selection.

•

Terminal T can be configured as an independent,

general-purpose input. It has no secondary function.
