Standard Feature Set

11. Automatic Compressor Throughput Control
The DE-3000 is capable of performing automatic compressor throughput (capacity) control on both screw and reciprocating compressors through regulation of engine RPM and compressor capacity
Engine RPM setpoint control is accomplished by connecting one of the 4-20mA control outputs to an electronic governor or to an I/P driving a pneumatic governor
4-20mA outputs can be used to control the capacity of both screw and reciprocating compressors
The CAPACITY 4-20mA output is typically connected on a reciprocating compressor to an appropriate I/P which is tubed to a pneumatically controlled external by-pass valve to adjust the load
This same output can also be used to drive an internal step-less bypass, a spring-biased turn valve, or a slide valve on a screw compressor application as a means of load control
DIGITAL OUT 1 (LOAD) and DIGITAL OUT 2 (UNLOAD) can be used to drive relay coils or pilot duty solenoid valves on a screw compressor

12. Automatic Compressor Throughput Control
Three PRIMARY control strategies are available in the DE-3000 system
Suction Pressure Control – Maintaining a fixed and regulated suction pressure, a large number of limited flow rate wells can be kept productive with minimal upset conditions
Typical of low flow, low supply, or vapor recovery applications
Discharge Pressure Control – Holding discharge pressure constant permits the flow of gas to be delivered at roughly the same rate as it is being consumed/transported upstream
Engine Manifold Pressure Control – Adjusting throughput of the compressor to maintain a fixed engine manifold pressure minimizes overload risk to the prime mover (the engine)
Typically seen on applications where the available gas is plentiful
This approach could also be used on an electric motor driven application in conjunction with a motor current or kW sensor as feedback to the controller

13. Throughput Control – Operating Sequence
Primary control (suction, discharge, or engine manifold) and corresponding setpoint is established
Start sequence is initiated (pre-lube, purge, crank), engine/compressor is warmed up, and speed is raised to minimum load-carrying RPM
Capacity control mechanism (slide valve, turn valve, bypass valve, etc.) is pulsed by digital output or actuated by a PID control loop to raise compressor capacity
If insufficient to meet capacity requirements, engine speed is increased to reach setpoint

14. Throughput Control – Operating Sequence
Other process variables can be used to influence the compressor loading/unloading process
FORCE UNLOAD – A parameter (such as discharge temperature) has been exceeded and demands that the compressor be unloaded to avoid potential damage
LOAD INHIBIT – A parameter (such as engine manifold pressure) has been exceeded and prohibits the application of additional load on the compressor to avoid potential damage

15. Auto Start Option
During system configuration, the user has the option of enabling auto start
Initiated by a discrete contact closure or appropriate serial string on RS-485
The Process
Internal reset to clear faults
Initializes pre-lube and crank delay timers
Class B and C points automatically disabled until cranking begins (then pre-assigned timers activate)
Pre-configured start sequence continues
