Coolant Temperature and Oil Pressure Inputs
The EGCP-2 has one analog input dedicated to sense engine coolant
temperature and one analog input dedicated to sense engine oil pressure. These
inputs are optional and once connected-to can be configured to protect the
engine by causing a system soft shutdown, hard shutdown, or alarm. To disable
these inputs set all related Shutdown/Alarm settings to their “disabled” state.
These inputs can be DIP switch configured to be compatible with 0–200 
sensors, 4–20 mA transducers, or 0–5 Vdc transducers. Depending on where a
0–200  sensor’s linear range is, this input can also be DIP switch configured to
vary sensor loading which will move the sensor output into the most linear part of
its range. Refer to Figure 3-4 for DIP switch location and to Figure 3-14 for input
wiring schematics.
