Introduction
Product Description
The Centurion configurable controller is a display and controller combination expressly designed to meet the requirements of three specific kinds of applications:
Screw Compressors
Reciprocating Compressors
Pumps
The heart of the Centurion system is the main input/output (I/O) module or controller, which can be mounted on a standard DIN rail. While it is designed to work with any Modbus (Client) compliant HMI (Human Machine
Interface) or with no operator interface at all, it is optimally configured and field-configurable using the Centurion
Configuration Tool, powerful software developed to configure the controller. Parameters can be modified in the field without special need for laptop or software by utilizing FW Murphy’s specially programmed M-VIEW controller display.
The controller is designed to monitor, control, protect and optimize small- to medium-sized gas operated compressors and pumps in the field. Proper operation is maintained by monitoring set points and digital, analog and temperature input points and providing the logic to take corrective and/or proactive steps.
The controller also allows for controlled shutdown and no-flow monitoring as well as auto startup and engine control capabilities.
The controller provides real-time data via communications ports to a connected display and/or supervisory system. This advanced system offers multiple options for remote communications and operation. The industry standard Modbus RTU or Modbus TCP/IP protocol means greater support for a wide variety of communication equipment including radio and satellite communications systems.

General Timer
General timers affect driver operation and also help define an event arming condition.
B1, B2 and S1-4 Timers are start-run lockout timers. Events configured to these class types do not arm for a specified time at start up.
C4 Timer is lockout until time after reaching a loaded condition.
No-Flow Timer is for class NF faults and enabled after the B1 expires.
Test Timer is time given to allow for maintenance testing of end devices without triggering a fault or shutdown condition.
Ignition On Timer and Fuel On Timer staggers the engines outputs at startup for engine fuel purge.
Ignition Off Timer allows unspent fuel to burn off after a stop.
State Timer
User may edit all state timers (except Panel Ready/Shutdown) if marked in use. When a state timeout value is reached, the state logic proceeds to the next in-use state.
A state timeout may also be configured to trigger a fault event, such as a prelube permissive failure; however, the operation depends on the configuration.
A setting of 65535 disables the timeout event.

Maintenance Timers
User may access and edit the maintenance interval presets and view the time remaining settings, if used by configuration.
If an interval time has elapsed, a message event is typically used to indicate maintenance is due.
Reset the timer after maintenance is performed by pressing the RST icon on this page.
Control Loop Setup
User may edit up to 8 configured control loop settings.
The settings on these pages differ depending on the type of control loop configured.
The control loops operate on the principle of a 0-100% output with special considerations for digital output loop types.

00-02-1032
Control Loop Typical
The pen chart shows the PID output (CO), Feedback (FB) and Setpoint over the last 2 minutes. Use this to help tune the closed loop control.
Press the Auto/Manual button change modes. In automatic, the control loop will try to maintain the setpoint +/- the deadband using calculation against the error (how far away from setpoint) of the loop.
Press the Manual Out edit box to set a desired output in manual if desired.
P = tunes for the Error at present condition.
I = adjust the output value on the accumulated error over time.
D = affects the output value based on the rate of change of the error.
Bigger numbers will result in larger changes in output %. General tuning guidelines start with I and D at low numbers, using only proportional. Once ringing is seen, reduce P slightly and increase I slowly. D may be introduced as a predictive measure, derivative adjust the output based on how much the error is changing in a given calculation loop.
Output ramp rates and min/max calculation limits are adjustable. Press loop overrides to adjust any possible control loop override factors.
The controller uses the parallel form of the PID equation as follows:
% Output = Kp(Error) + Ki∫(Error)dt + Kd×dErr or∕ dt
