Safety Notes Proper use
1.2
Only operate the KCM in conjunction with the feeder equipment from K-Tron.
Only operate the KCM in accordance with the specified technical data.
Do not operate where there is a risk of explosion.
Do not use the equipment in a manner not intended by the manufacturer.
1.3
Organizational measures
Observe the safety notes for the connected feeding devices.
In addition to the operating instructions, always comply with generally prescribed safety regulations governing accident prevention and environmental safety.
Always keep the metering device operating instructions within easy reach. Ensure that they are always complete and legible.

Proper use
Operator responsibilities
Ensure that only qualified and trained personnel work with the KCM.
Establish personnel responsibilities for operation and maintenance.
Ensure that personnel have read and understood the operat ing instructions to all installation components, particularly these safety notes.
The operator must have damaged or missing components replaced immediately.
The operator of the KCM is responsible for compliance with the legally prescribed accident and safety regulations.

Safety-conscious operation
Any changes (including changes to operational behavior) which affect safety must be immediately reported to the responsible member of staff.
Perform all operations with safety in mind.
Do not make any internal adjustments to the KCM while the feeder is in operation.
1.6
Safety devices
The electrical safety devices must not be altered. This increases the danger of accidents.
Never operate the KCM with the housing open.
Replace damaged cables and connections immediately.
Only operate the feeding equipment if all safety devices are installed and fully functional.
Check that the safety devices on the KCM and on the feeding equipment operate properly daily.
Never open or remove covers or hoods while the feeding equipment is in operation.
If accessing KCM internal components, allow 10 seconds to lapse prior to opening the enclosure. This ensures safe discharge of high voltage components.
1.7
High voltage
Warning! Danger!
!
DANGER
High voltage of 230 Vac may be present on the line power cables of the KCM.
Switch off the power to the KCM for 3 minutes before:
– any disassembly, maintenance and repair work – replacing the motor. Only qualified electricians may work on the KCM.
Docu-No.: 0590020612-EN Rev. 1.0.0
Protect the KCM against moisture entrance.

Data Structures, Formats and Data Types for SmartConnex-II
This document presents the numeric and digital data that is available via the KCM Smart K-Link connectivity function. The KSL needs to be at ver. 4 software.
2.1
Overview
Two sections are presented. The first section presents a summary table of the variables that may be selected in Smart K-Link and the second shows the index settings used when binary or bit data is selec ted. Command, Alarm and Process Status functions fit this later category. Please use the following notation when using these variables. Data Type: Numeric - Float, Strings or Integer Data Types, Digital - Bit Arrays Typically used variables: Marked in Bold typeface. For PLC register assignments, use: Float, string, bit array: 2 registers Integer: 1 register Access information:’R’ means Smart K-Link output only,’R/W’ means the variable is both an input and output value. Units of time are generally in seconds unless otherwise specified. Using string data may require setting of an ASCII data block in the PLC. Then select ASCII in the Poll Record Table. It is recommended to use floating point rather than integer math. This will eliminate the need for scaling.

Data descriptions
There are different types of data that can be exchanged amount devices. This will help you to identify them. 2.2.1
Data types
Data types are broken into three major categories: ·Commands ·Status ·Variable or process data Commands are requests for an action to be taken by the controller. These mnemonics begin with the letter ’C’. Status information is a report on the operating condition of the controller. These values can be bit mapped or brought back as full 16 bit arrays for a total of 256 bits. What is left is the process data or such things as setpoint and massflow. For clarification of mnemonics, use this list. 2.2.2 Application
