PROFESSIONAL EXPERIENCE

SUNDYNE CORPORATION, Arvada, Colorado 2005-Present

Senior Controls Engineer & Field Service Engineer

Controls Engineer: Responsible for API-compliant high-speed centrifugal compressor control system

packages used primarily in oil and gas applications. Project duties include EPC/end-user

specification review, skid P&ID input, control narratives, C&E matrices, memory maps,

panel/junction box designs, wiring schematics, skid electrical kit BOM, hazardous area component

review, PLC/HMI programming, MMS and anti-surge control interfaces, system implementation and

testing, customer witness FAT’s and site commissioning support. Additional duties include

applications/sales support and factory floor compressor/pump test stand support.

Field Service Engineer: Responsible for site commissioning of high-speed centrifugal compressor

skid installations including mechanical performance, auxiliary system checkout and control system

functionality. Specific duties included pre-commissioning activities such as lube oil flushing, seal

system blow-downs, instrument loop checks, main motor coupling alignments, piping walk-downs,

DCS/SIS/MCC signal interface testing followed by commissioning activities such as

startup/shutdown and trip sequence testing, compressor performance validation, and compressor

operation and training for the end user. Significant international travel experience.

TIMBERLINE AUTOMATION, Littleton, Colorado 1997-2005

Systems Integrator / Controls Engineer

Responsible for all phases of controls integration projects over a wide range of industries. Typical

duties included project management, client collaboration regarding control strategies, control system

design, programming, procurement, installation and training. Broad project experience with a variety

of automation equipment including PLC’s, HMI’s, stepper and servo systems, motors and drives,

machine vision, pneumatic components and process control. Experience with mechanical design for

machine components when workload demanded additional project support.

B-TEN SYSTEMS, Arvada, Colorado 1990-1996

Controls Engineer

Responsible for overall control system design, procurement and implementation on custom

manufactured automation equipment. Primary focus was on assembly workcells for an automotive

safety products manufacturer. Project duties included development of machine control strategies,

panel layout and schematic drawings, PLC and HMI programming, servo and stepper controller

integration, pneumatic valve layouts, startup activities and site installations.

TYPICAL PROJECT EXPERIENCE

(Sundyne) Control Package – Produced Gas Compressor Application for large EPC

Two 2-stage IG compressor (1500 HP) skids designed for parallel operation with load sharing

capability. Auxiliaries included lube oil and seal support systems. Project value $5M.

IP56 Local Start/Stop stations with Allen-Bradley PV+1500 HMI’s and skid instrumentation

designed and wired for installation in a Zone 2 IIB T3 hazardous area.

Remote panels in the field rack room housed all control hardware including redundant Allen-

Bradley ControlLogix CPU racks and IO rack. Redundant ControlNet network for communication

with HMI’s locally and in the field.

Bently-Nevada 3500 racks for continuous machine monitoring and protection of the compressor

from high shaft vibration and/or high bearing temperature. Hardwired shutdown signals wired to

the PLC discrete IO. Vibration and temperature data read back to the PLC through a redundant

RS-485 Modbus connection.

Five CCC S3++ dedicated controllers for anti-surge, load sharing and master performance

control. All controllers networked and interfaced to the PLC via hardwired IO and a redundant

RS-485 Modbus connection. Controller algorithms modulated suction throttle valves and recycle

valves to keep compressors out of surge and load balanced.

DCS – PLC interface through redundant OPC Ethernet connection.

MCC/SIS – PLC interface through discrete IO.

Skid instrumentation - Rosemount pressure, temperature and level 4-20mA HART transmitters,

3-wire P100Ohm RTD’s, Bently-Nevada 3300XL NSV proximity transducers, FCI thermal mass

flow transmitters.

(Timberline) Band-It, IDEX Automated Clamp Assembly Workcell

Automated assembly machine to turn a roll of band steel into formed clamps with positioned

buckles. Primary mechanisms included a band feed servo station to position the steel band under

compound forming die, indexing servo station to increment the band through the compound die

operations, buckle load, vision inspection, and servo offload stations. Project value $600K

Control platform hardware included Allen-Bradley ControlLogix PLC with Sercos motion control

interface, servo motor drives, Cognex InSight machine vision system and ancillary support

hardware of backlights and power supplies.

PC-based operator interface developed in VB6.0 which used third-party ActiveX control software

to communicate with the PLC. Additional remote interface via an Allen-Bradley PV600.

Discrete I/O included switches, proximity sensors, photo-eyes, interface relays, pneumatic

solenoids, and contactors for fractional HP motors.

Analog I/O included laser measurement sensors and modulating pressure regulators.

(Timberline) Bedrock, Inc. Rock Crushing Plant Control System

In the role of sub-vendor to the primary electrical E&C firm, programmed and commissioned the

control system for a rock crushing plant. Project value $3M.

Control platform included Allen-Bradley SLC-500 PLC with DH+ remote I/O for plant interface.

Allen-Bradley RSView32 for operator display (HMI).

PLC carried out sequencing of all conveyors, feeders, screeners and crushing equipment (jaw

crusher and cone crushers) along with monitoring for alarm and shutdown conditions.

Discrete I/O included status from the MCC, limit switches, and commands to the MCC.

Analog I/O included conveyor scales, level transmitters, and feeder rates.
