3.4 Sensor Inputs

The GSC400 has support for the following sensor types:

Engine Parameter

Advanced Menu Location

High Engine Temperature

High Engine Tmp

Oil Pressure

Fuel Level

Oil Level

Fuel In Basin

Low Engine Temperature

Low Engine Tmp

Auxiliary Analog 1

Aux Analog 1

Auxiliary Analog 2

Aux Analog 2

Negative engine temperatures are not allowed for the sender inputs on the GSC400.

The above sensor types can be set to a switch, sender (sender1, sender2,

sender3), or J1939. This is done in the Signal Source menu. The switch and

sender choices are covered in this section. For J1939 refer to section 3.8 on

page 63.

For each of the sensor input types, you must select the pin (2 to 7) that the

sender or switch is connected to in the Input Pin menu. See Figure 4 on page

17 for the pin locations of the sensor input connector. If you are not using one of

the inputs then select Disabled. Two different sensor types cannot share the

same pin with the exception of the Low Engine Temperature and High Engine

Temperature.

A Bypass Time can be selected for each input (this applies to J1939, senders,

and switches). After crank success, the bypass period will start, and during this

period the controller will not enable the warning or failure checks for this input.

After the bypass period, if there are any warnings or failures they will be

Input Pin Disable Note

When the Input Pin is set to disabled it is actually set to a virtual input where

the voltage read is 5V, the signal source is set to a switch, and the switch

setting is set to “Closed = Fail”. This effectively disables the input. If

changing the signal source, ensure that the Input Pin is not set to

disabled.

If you disabled the Input Pin and are still seeing the warnings/failures for the

parameter, set the Input Pin to an available pin, then set it to Disabled again.

This should fix the issue.
