Precision matters, especially when life safety is involved.

CSE is proud of the craftsmanship that goes into every fire & gas control panel we build.

Clean wiring. Clear labeling. Quality in every detail.

A 2025 retrofit by CSE Services for a foam looping & cutting machine that included demo of the existing panel and design, programming, installation and startup of the new main Allen Bradley panel and two operator stations.

The system provides control to cut long sheets of foam (0.25" - 2.5" thick) from a much thicker "bun" of foam (~4ft thick). The "bun" is glued end-to-end so sheets can be cut much longer than the length of the original bun. In order to maintain precise thickness, the blade head has to drop at the same location and at the same slope regardless of the speed of the conveyor. This was accomplished using a position cam between the main belt conveyor and the blade head. The position cam was triggered by a color sensor looking for a red stripe on the side of the foam so the blade head can drop at the same position every "loop."

Safety modifications were a big priority for the upgrade. The safety program provides safe-torque-off for all VFDs as well as safe-speed monitoring for the main belt conveyor VFD. This was accomplished with 20-750-S4 integrated safety module for the PowerFlex 755 and redundant encoders. Safe-speed monitoring was used to enable the main belt conveyor to run at a low speed during the glue setup operation as it required an operator in the safety scanner zones.

A recovery routine was added to salvage the sheet in process when a fault occurs. Previously, the sheet was rejected in different scenarios like an E-Stop being pressed during a drop. The recovery routine involved starting a position cam immediately (as opposed to a sensor trigger) and calculating different endpoints based on the remaining distance.

Challenges overcame with this project included the windup VFD needing to run by a ratio of the main belt speed but also have a tension adjustment by the operator with a potentiometer. This was accomplished by gearing the windup to the main belt and then adding a jog on top of the gearing based on the tension adjustment by the operator. Also, the machine had to be able to change the thickness setpoint in the middle of a drop. This required the position cam to be setup with the same slope for all thicknesses.

The completed retrofit improved safety, reliability, and process precision while extending the life and capability of the original machine.

CSE recently completed a rush order for six control panels that each control six 30HP pumps as part of a chilling system for a data center. Each PLC is programmed to provide pump ordering and start/stop sequencing with 3 selectable control modes. The pumps can be controlled to maintain a header pressure set-point, a header differential pressure set-point, or can be limited by total current draw on the system. Each panel was custom crated and shipped directly to the facility.

CSE Services recently completed a multi-phase installation and commissioning of a new overhead chain system controls package for a beef plant kill floor. The original SEW Eurodrive VFD system, installed by CSE nearly 15 years ago, was incrementally replaced over 20 weekends with Allen-Bradley AC Powerflex drives within the existing enclosures.

Using redundant hot-swappable motors and VFDs to minimize downtime, the control scheme deployed Rockwell’s CIP Motion technology to electronically gear each chain to a master virtual axis, achieving precise speed control at rates up to 390 head/hour.

During the upgrade, the Allen-Bradley system “followed” the SEW system via an analog motion module (1756-M02AE) acting as the master axis. Drives were swapped weekend by weekend, with Powerflex 755TS drives geared to the analog motion axis by a gear ratio until the SEW drives were fully replaced and the system switched to an electronic master virtual axis.

One drive was configured to “help” another on the same chain, geared to the primary drive (not the master) with speed trimmed to balance torque output.

Additionally, the system was designed to create chain space to insert re-worked cattle from the inspection platform by stopping and re-synchronizing groups of chains using cascaded virtual axes and a position cam.

A complex, high-precision upgrade delivering advanced control and reliability for critical production.

CSE recently participated in a controls upgrade for a flying cutoff machine. Using a line encoder, analog motion module, a PowerFlex DC drive, and a FactoryTalk Optix HMI application, the cutoff synchronizes with the speed of the mill to cut the pipe to millimeter precision.

Starting off our week with a freshly completed set of control panels ready for shipment to the customer. This collection of panels house 80 VFDs that will control cooling fans for a refrigeration system. This system will operate in concert with existing controls and utilize an algorithm that compensates for temperature and time of day to provide tighter fan control and reduce overall energy consumption. The customer will see significant energy savings following the installation of this system.

Another Allen-Bradley Powerflex 525 drive application under way! One of the many benefits that come from upgrading to VFDs is efficient management of energy consumption. This panel will be integrated with a refrigeration system that has variable power demand.

CSE recently completed this control panel that will be part of an overhead chain system in the beef industry. The PowerFlex 755 VFDs will be controlled via Allen-Bradley’s CIP motion to perform synchronous running of the various chains involved. Each overhead chain has a redundant pair of “hot-swappable” motors and VFDs to minimize downtime. The HMIs involved will have full diagnostic and maintenance functions as well as control of each drive.
