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 setpoints 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 start up 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.
Led Indicators
MV-5-C Display – Front Side
Please be aware of the following conditions and the resulting LED appearances:
If the unit has an invalid application or needs to sync (M-VIEW Replacement only), the Red LED is
Off and the Amber LED will Flash.
When the bootloader exits to run the application, the Red and Amber LEDs are turned Off.

MV-5-C Display – Back Side
The LEDs are located next to the serial port connections.
All Ports RX/TX LEDs include:
The serial activity LEDs blink with every transmitted or received message. o
The RX LED blinks Red when a packet is received by the display. o
The TX LED blinks Green when a packet is transmitted by the display.
C5-1 Controller
NOTE: The Expansion modules have the same 2 Power LEDs and COP blink codes as the C5-1. They are located next to the power plug on all modules.
C5-1 Power LED Indicators – Power is always two green LEDs
2 Green LEDs :
2 on - Unit is powered normally
1 on - Internal power failure. Needs service
Off - No DC power to unit
C5-1 COP LED Indicators – Controller Operating Properly
Green LED:
1 Blink/sec - Unit is running application normally
Fast blink - Bootloader mode
3 Blinks - Missing configuration
4 Blinks - Running in recovery mode
Off - Controller not operating

C5-1 Digital Input LED Indicators – Digital Inputs
Green LED:
On - Input active (DC+ or -)
Off - Input active (open)
C5-1 Digital Output LED Indicators – Relay Outputs, FET DC+, FET DC-
Green LED:
On - Output on
Off - Output off
C5-1 Communication LED Indicators - RS232, RS485, CAN bus
RED LED:
Flash - Unit is transmitting data to device
Off - No communication active
GREEN LED:
Flash - Unit is receiving data
Off - No communication active
RS232 RS485 CAN bus
C5-1 DIP Switch Setting
Switch 1-8: Modbus Server Address function for RS485-2 / RS232-2
Selectable 1-253
If set to address 0, RS485-2 and RS232-2 ports default to 9600 baud.
Set to address 1 to connect to the controller if settings are not known. This is the default setting from the factory.
Switch 9: Set to ON to enable CAN1 line termination if C5-1 is at the end of the CAN bus network.
Switch 10: Set to ON to enable CAN2 line termination if C5-1 is at the end of the CAN bus network
