Contact Sensing
Contact sensing inputs include seven programmable inputs. All inputs accept dry contacts.
Time from a DGC-2020ES input application to:
•
Shutdown the generator via an alarm = 490 ms max
•
Close a relay on board the DGC-2020ES = 215 ms max
•
Close a relay on board the CEM-2020 = 400 ms max
Notes
A contact input is true (on) if the input is connected to battery ground
with a resistance of less than 240 ohms.
The maximum length of wire that can be accommodated depends on
the resistance of the wire, and the resistance of the contacts of the
device driving the input at the far end of the wire.
The maximum wire length can be calculated as follows:
L
max
= (240
– R

)/(Resistance per Foot of Desired Wire)

Engine System Inputs
Stated accuracies are subject to the accuracy of the senders used. Values within these ranges are
deemed “good” and the DGC-2020ES will use them for the appropriate calculation and protection. Values
outside these ranges are deemed “bad” and the DGC-2020ES will begin timing towards a sender failure
condition.
