Do Kolver tools support Open Protocol?
Yes! Kolver's K-DUCER line supports Open Protocol, an industrial communication protocol to remotely control and monitor screwdrivers.
Many Manufacturing Execution Systems (MES) already come with built-in support for Open Protocol, and now they can interface with the K-Ducer systems - all plug&play with no need to build your own communication interface!
How do I enable I/O for remote programming using the EDU2AE/TOP, EDU2AE/TOP/TA & KDU-1A series controllers?
You can easily activate the corresponding I/O blocks for remote programming using the following steps.

Using the controller's keypad, go to the Sequence Settings menu and select "Ext Box", once this is turned on you can move back to the main screen and the CN2 I/O port will be activated and ready for use. The instructions can be found on page 10 of the EDU2AE/TOP & /TA Operation Manual
KDU-1 & KDU-1A 

Using the touch screen interface, go to the General Settings menu and select "Remote Program", once this is turned on you can move back to the main screen and the CN3 I/O port will be activated and ready for use. The instructions can be found on page 22 of the KDU-1 & 1A Operation Manual
How do I calibrate a MITO or PLUTO current controlled system?
When looking at the MITO or PLUTO current controlled systems there are two distinct calibrations methods.

With either method it is important to note the controller's torque % be set appropriately as this is one of two determining factors of torque output. The second consideration takes speed into account since speed does directly effect the output torque in current controlled fastening systems.

It is important to note the "Kolver" calibration method is only found on the EDU2AE/Hpro and EDU2AE/TOP & TA series controllers.

Standard method: This work is typically done by a certified calibration laboratory or a company's internal QC or Cal department. However you can check the high/ low torque range using a calibrated torque tester like our Mini K/S series.

1. The standard method is to run a test at the low and high torque ranges of the screwdriver. 

Example of low, medium and high strategy would be to set the system at

Low: Min torque % and min speed setting
High: Max torque % and max speed setting

2. The "Kolver" method allows you to teach the EDU2AE/Hpro, /TOP & /TA controllers how to represent on the display screen the numeric values shown on a calibrated torque tester. The goal of this method is to follow a simple set up process and then be able to see the target torque value represented on the display screen after each succesful event. The steps for this process can be found on pages 9 - 10 of the EDU2AE/TOP operation manual;

Kolver Current Controlled Calibration Procedure
Why do you recommend against using a electric screwdriver continuously over 80% of its max torque capability?
The general industry standard is to not continuously use a motor-based screwdriver (air or electric) over 80% of its max torque capacity. 

In general terms, using any motor-based product at the high end of its rating can cause premature gear and motor failure. The result is a reduced life expectancy as compared to normal usage below the 80% threshold.

If we think of this question in terms of an automobile, running your car near its maximum rated speed continuously will result in the same general effects of premature breakdown and engine failure.
Why is it important to use a torque tester to properly set up clutch controlled fastening systems?

With Kolver's clutch controlled fastening systems, FAB, RAF, KBL & PLUTO/FR series it is important to use a calibrated torque tester like the Mini K/S series to pre-set and validate torque output.

Q: Why do I need to use a torque tester?
A: Calibrated torque testers allow you to view torque output from the fastening system and based on these readings make adjustments to the clutch in order to acheive the desired target torque output.

Q: Do any controller settings affect torque output? 
A: Yes, both ramp and speed control settings can directly change output torque. After any change is made to ramp, speed or clutch settings the system should be rechecked using a calibrated torque tester.

Q: What are the numbers I see on the screwdrivers clutch?
A: These are reference numbers enabling you to record where the clutch has been set after the validation process. After setting up one screwdriver this will allow you to reduce time and quickly prepare additional units of the same model for torque tester based validation.
