The BST ekr ProCom 40 is a compact, CANopen-based web guide controller designed for precise material positioning in web-processing industries. As part of the BST ekrPro family, it provides a flexible solution for guiding untreated or finished material webs by their edges or center-lines. Core Technical Specifications
The ekr ProCom 40 stands out for its high performance-to-size ratio and integration capabilities. Supply Voltage: 24V DC.
Communication Interface: CANopen Bus protocol for seamless connection with standard commercial components.
Inputs: Supports analog scanning systems (e.g., 0–10V or 0–5V).
Compatibility: Directly connects to a wide range of motor-driven actuators, from the EMS 5 up to the EMS 20, with or without position potentiometers.
Protection Class: Typically rated at IP 54 to withstand industrial environments.
Weight: The controller unit weighs approximately 1.5 kg (3.3 lbs). Operating Modes & Guiding Functions
The system is controlled via a dedicated panel that allows operators to switch between several critical functions:
Automatic Mode: The system actively corrects the web position based on sensor feedback to ensure precise alignment.
Manual Mode: Allows the operator to manually position the guiding device using arrow keys.
Center Positioning: Automatically moves the guiding device to its center-line position, typically used during setup or material changes.
Guiding Options: Operators can select between guiding to the left edge, right edge, or the center-line of the web. Compatible Sensors & Hardware
The ekr ProCom 40 is engineered to work with various BST sensors to handle different material types: bst ekr pro com 40 manual pdf
Ultrasonic Sensors: Ideal for materials that are light-sensitive or have variable transparency; these sensors are insensitive to dirt and web "flutter".
Infrared Sensors: Used for non-contact scanning of web edges; these include automatic contamination alerts and are unaffected by external light.
Digital Sensors: Can be integrated for advanced line or contrast guiding. Installation and Maintenance
Manuals for the ekr ProCom series emphasize specific setup protocols to ensure longevity and accuracy:
Site Requirements: Must be installed in a dry, vibration-free area.
Networking: Multiple controllers can be networked via CAN-bus, allowing for complex multi-point guiding systems.
Remote Operation: If the controller is hard to reach, the ekr commander control panel can be detached and mounted at a central station using an extension cable. ekrPro Com50 Web Guide Controller Manual | PDF - Scribd

It was 7:00 AM on a Tuesday, and the loading dock at LogiTrans Shipping was already chaotic. A semi-truck full of high-value automotive parts had arrived, and the driver was in a rush.
Marco, the shift supervisor, stood in front of the BST EKR PRO COM 40, the facility’s heavy-duty weighing terminal. This machine was the heart of the outbound operation—it communicated with the floor scale, printed the shipping labels, and logged the data into the warehouse management system.
Marco tapped the 'Tare' button. Nothing happened. The display, usually a bright red beacon of weight readings, was frozen on a cryptic error message: "ERR 05."
The driver tapped his watch. "I’ve got a delivery window in two hours, Marco. If we don't get this weighed and loaded, I’m leaving." The BST ekr ProCom 40 is a compact,
Marco felt the sweat on his neck. He tried turning the terminal off and on again. It beeped twice—the standard startup—but then immediately returned to "ERR 05." He checked the physical connection to the floor scale. It was secure. He checked the power cord. Fine.
"If this thing is broken," Marco muttered, "we’re going to have to use the old manual scale in the back, and that will take three times as long."
Just then, Elena, the inventory specialist, walked by with a tablet in hand. She saw Marco panicking.
"Terminal acting up?" Elena asked calmly.
"It's dead, Elena. Error 05. I think the mainboard is fried," Marco sighed, reaching for the phone to call IT support.
Elena shook her head. "Don't call IT yet. You'll be on hold for an hour." She set her tablet down on a nearby crate. "Do you have the manual?"
"It's a machine," Marco grumbled. "I tried the power cycle."
"Marco," Elena said firmly, "The BST EKR PRO COM 40 isn't a toaster. It has specific error codes. When was the last time you saw this error?"
"Never."
"Exactly." Elena tapped on her tablet. "I downloaded the BST EKR PRO COM 40 manual PDF last month when we updated our software. I keep a local copy for exactly this reason."
Marco watched as she scrolled through the digital document. She didn't read the whole thing; she went straight to the Troubleshooting section, then the Error Code Appendix.
"Here it is," Elena said, pointing to the screen. "Error 05. It doesn't mean the board is fried. It means 'Communication Timeout with Peripheral Device.' It thinks the label printer is disconnected." Critical Parameter Table (Excerpt from PDF) | Parameter
Marco looked at the printer sitting beneath the terminal. It was on, but the little green 'Link' light wasn't blinking.
"The manual says," Elena read aloud, "'This error often occurs if the internal buffer overflows or if a cable is loose. Solution: Reset the interface by holding the 'Shift' and 'Test' keys simultaneously for three seconds.'"
Marco looked at the keypad. He found the two keys. He pressed them and held them down.
Beep.
The screen flickered. The error message vanished. The display lit up with a bright, welcoming 0.00 kg.
"Try printing a test label," Elena said.
Marco tapped the 'Print' button. The printer whirred to life and spat out a configuration label.
"You're a lifesaver," Marco exhaled. "I was about to spend the morning on the phone with tech support."
"It's not me," Elena smiled, picking up her tablet. "It’s the documentation. The manual also has the calibration steps and the RS-232 pinout wiring if you ever need to hook it up to a PC. You should keep that PDF on your phone."
Marco weighed the pallet, tagged it, and signaled the forklift driver. The crisis was averted in under five minutes, all because someone had taken the time to search for, download, and consult the PDF manual.
| Parameter | Range | Description | Default | | :--- | :--- | :--- | :--- | | P04 | 0-999 | Proportional Gain (Speed of correction) | 50 | | P05 | 0-999 | Integral Time (Steady-state accuracy) | 100 | | P06 | 0-999 | Derivative Time (Stability) | 0 | | P08 | 0.5-10.0mm | Deadband (Dead zone before correction) | 1.0mm | | P11 | 0/1 | Actuator direction normalize/reverse | 0 | | P20 | 0-9999 | Service code (Password lock) | 0000 |
Pro Tip from the Manual: If the web oscillates (hunts), increase the deadband (P08). If the response is too slow, increase P04.
