Analog Inputs
The GSC400 has support for the following analog input types:
1.
High Engine Temperature
1
2.
Oil Pressure
3.
Fuel Level
4.
Oil Level
5.
Fuel In Basin
6.
Low Engine Temperature
2
For each of the analog input types, you can select the pin (2 to 7) to connect to in the
Input Pin
menu. See Figure 4 on page 9 for the pin locations of the analog input
connector. If you are not using one of the inputs indicated then select Disabled. Also,
you must select a pin even if you are using J1939 instead of a physical sender or switch.
Two different analog types cannot share the same pin with the exception of the Low
Engine Temperature and High Engine Temperature as this allows the user to use one
sender to measure both low engine temperature and high engine temperature.
Attaching Switches to the Sender Inputs
The user has the option of connecting either senders or switches to the analog inputs. If
using switches they must be switched to ground but can be either normally open or
normally closed.
Set the “Signal Source” menu to “Switch Input” and the “Switch Setting” menu to
“Closed = Fail” for normally open switches or “Open = Fail” for normally closed
switches.
If the Input Type is set to a switch in the Run Mode (see section 5.3 on page 22) the
controller will display “SW” in place of the value that would be displayed if it was set to
J1939 or Sender.
When the switch becomes active the controller will shutdown the engine with the
exception of Fuel Level where you can set the controller to either shutdown or generate a
warning.
1
Negative engine temperatures, can be displayed on the GSC400 but any reading below 0
0
C (32
0
F) is set to
0
0
C for warning and failure level detection purposes (e.g. low engine temperature, high engine
temperature).
2
Same as (1) above.
