This document describes a compressor control solution that provides configurable control sequences, logging, alarming, reporting and security features. It allows optimization of energy use, increased uptime and performance, and reduction of emissions. The control solution is highly configurable and customizable through its interface to eliminate the need for on-site service visits.

1. Compressor Control Solutions

2.  Gas compression
 Water injection
 Vapor recovery
 Power generation
 Three-phase pumping
 Acid gas injection

3.  User specific security
 Detailed I/O configuration
 Operation control characterized by configurable
sequences.
 Limitless logging of analog signals
 Event and alarm logs
 Customizable trends
 Two customizable engineering units, e.g. psi/kPa
 Support for multiple languages
 Remote control
 Detailed, customizable reports

4.  Optimize energy use
 Increase uptime
 Increased machine performance
 Reduction emissions
 Highly configurable design allows user to
eliminate site service visits for possible
modifications, troubleshooting, etc.

5.  Three security levels
◦ Engineering
◦ Maintenance
◦ Operators
 Unlimited number of users
 Users database created and maintained from
the touch-screen
 Any user actions logged in the event log.
 For multiple control panels, ability to create
common, distributed database of all users

6.  Complete configuration - descriptions, scaling
and alarming
 7 custom alarms for each Analog Input: HH, H, L,
LL, Over-range, Under-range, Open Circuit
 4 alarm types
◦ Type A – always armed
◦ Type B – armed only for specified control sequences
◦ Type C – disabled during start
◦ Type D – special alarm designed to tie discrete signal
with the feedback from the activated device, e.g. valve
control DO and feedback from valve limit switches

7.  Full configuration of up to 32 PIDs
 Control divided into 30 customizable
sequences
 Each sequence characterized by:
◦ Min/max time length
◦ Up to 10 parameters to be fulfilled before the end
of the sequence (permissives)
◦ Up to 45 actions. Actions can relate to any I/O
signal and/or PID
◦ Optional alarm triggered by failing permissives

8.  Main control screen
 PID screens – up to 8 with individual tuning
trends
 Overview screen
 3 screens with up to 40, user specified
process parameters
 Pyrometers screen
 Application specific screens, e.g. scrubbers,
blowcase, screw compressor screens

9.  Bypass of alarms for each Analog and
Discrete input
 Forcing Discrete Outputs
 User defined operation alarms, e.g. Change
Engine Oil Alarm
 Ability to change time from the screen for
HMI and PLC
