User manual

Each sender has a particular pin it is supported on. If your sender part number is

not listed in the table or your desired pin is not supported, the PC Configurator

can be used to create and store a custom table (refer to manual MAN-0079, the

GSC400 PC Interface manual).

The GSC400 has Open and Shorted sender diagnostic features. These are

disabled by default. The Open Sender Detection will trigger if the analog input

voltage rises above 4.76V. The Shorted Sender Detection will trigger if the

voltage drops below 0.122V. You may not be able to enable these features as

some sender tables encroach on these voltages.

2.6.3 Electronic Sensors – 0 to 5VDC

If you have an electronic sender that outputs a voltage between 0 and 5VDC

you can use it on the GSC400. You will need to create a sender table for it. See

manual MAN-0079 (GSC400 PC Interface Guide) for information on creating

and using sender tables.

Only pins 2 and 6 will give the full range of the sender. The other inputs have a

gain of three which will multiply the analog signal of the electronic sender three

times thus limiting it to the range 0V to 1.33V. It is recommended to use pin 6

because its 5.11k Ohm pull-up will have less of an effect on the voltage input of

the electronic sender than the 1k Ohm pull-up of pin 2.

For firmware versions 2.04.06 and above, the Sensata electronic oil pressure

sensor supplied by Dynagen works out of the box on “Sender 3” or “Sensata” in

the oil pressure signal source menu on pin 6.

2.6.4 Troubleshooting

 Symptom: High Engine Temperature reads around 130

This is normal when engine temperature is set to pin 3 or 4. Set to “Dat Pin2”

(firmware 2.04.06 and higher) and change sender to pin 2. For firmware

2.04.03 and below set signal source to pin 2, and then once this is done

program the “DatCon K – LowZ” to the controller using the GSC400

programmer and PC configurator. The high engine temperature will then read

down to 72

 Symptom: High Engine Temperature or Low Oil Pressure not reading

correctly.

(Note applies to Dynagen supplied mechanical senders only. For

troubleshooting on the electronic oil pressure sensor, refer to the insert that

came with that sensor.)
