Process Import/Export Hardware
• EGCP-2 Control can take a 4–20 mA, or 1–5 Vdc input signal from a
transducer. Input signal conditioning is selected by a dip switch on the back
of the control, switch position 4, switch number 4. Closing this switch selects
the 4–20 mA input hardware. Opening this switch selects the 1–5 Vdc input
hardware. See the EGCP-2 layout diagram for switch location on the unit.

Process Dynamics
• Process Master Uses Process PID to control.
• Gain, Stability, Derivative, Filter, Droop.
• Slaves to the Process Master use Load Control PID Values to track master
system load reference.
• Load Gain, Stability, Derivative, Filter.
Process Gain
• Sets system gain response while in process control.
• Effective at active master unit only. Slaves rely on Load Control dynamic
settings to control response to master load reference.
• Should be set with maximum number of units operating in process control
mode.
