Weighing display
INTRODUCTION
2011KCI and 2211KCI are input cards specially designed for Konecranes. They can be placed in any of Nokeval E and F series large displays, like
1000F4.
The card provides one (2011KCI) or two (2211KCI)
2-8 V analog input channels. The upper end of these can be scaled freely, and independently on each channel.
These models have been superceded by 2012KCI in spring 2007.
A separate Technical manual is available on request, covering more details of the KCI displays.

ORDERING
Ordering
Obsolete
It is recommended to replace the 2011KCI and
2211KCI by more advanced 2012KCI, which has been available since spring 2007.
Order code
Example: 1000F4 – 2011KCI – 230VAC
The order code consists of several parts. The first part describes the large display type, the next part defines the input card type, and the last part selects the supply voltage.
Large display type
Nokeval has four cases for large field displays.
These are:
575 Five 57 mm digits, plastic enclosure
1000 Three to four 100 mm digits, steel
1100 Five to six 100 mm digits, steel
1800 Three to five 180 mm digits, steel
The letter after the case size is either E or F. This tells the type of the internal electronics. They are principally the same but have different looks. The main difference is that the input card is upside down in the E chassis. Since beginning of year
2003 all displays have been with F chassis.
The number after the letter defines the number of display digits.
Input card type
These large displays use Nokeval 2000 series input cards. Custom input cards 2011KCI and
2211KCI have been designed for KCI.
Power supply options
Before summer 2009, the large field displays have been available with three power supply options:
Name
-24VDC
-48VAC
-230VAC
Voltages
24 VDC
48 VDC or VAC
115 or 230 VDC or VAC
After summer 2009, the input voltage range of the
230 VAC model has been extended to cover the range 41...265 VDC/AC, removing the need for a separate 48 VAC model. The voltage options are:
Name Voltages
-24VDC
-48/230VAC
24 VDC
48, 115, or 230 VDC or VAC
Common models
1000F4-2011KCI-48/230VAC: four 100mm digits,
1 input, power 48 to 230 VAC.
1000F4-2211KCI-48/230VAC: four digits, 2 inputs, power 48 to 230 VAC.

Opening the case
To access the electrical connections and the small user interface used for configuring the unit, the steel case has to be opened. First unscrew all the screws surrounding the display, then lift off the black steel frame and the red plexiglass. Finally unscrew the screw that is located on the right hand side of the rightmost digit. Now the display assembly may be turned away on its hinges.
Inside the main case
The electronics unit
The electronics unit may be opened or detached from the case. To open it, unscrew the four M3 screws that are holding the cover on its corners. If the unit has to be detached, unscrew the other screws on its top and bottom sides. Normally there is no need to open the electronics unit. Caution! Opening the electronics unit exposes parts carrying lethal voltages on units powered with more than 24 V supply!

Connect the Protective Earth wire to the M4 screw using the Faston connector provided - a Faston crimping tool is needed.
For electrical safety, the power and signal wires must be fastened using cable ties or equivalent so that if one signal wire is detached, it can not touch any of the power supply wires, or vice versa.

Configuring
The display unit may be configured either on the small display and buttons inside the main case, or with a programming cable.
Inside buttons
Open the main case as explained above. Use the small display and four buttons to configure the display unit. Using the buttons is explained in chapter User interface.
Via a programming cable
Using the programming cable is possible only on models equipped with circuit board ”2012” in slot A.
The programming cable is attaced to a pin header marked "POL" on the input card in slot A. To access it, both the main case and the electronics unit cover have to be opened. Removing the electronics unit cover exposes parts carrying lethal voltages on units with supply voltage more than 24 volts!
Nokeval provides two alternative programming cables: "POL-RS232" for RS-232 port, and
"DCS772" for USB port.
In addition, an adapter for the pin header, called
"POL-3PIN", is required.
A free software MekuWin is used, available for
Microsoft Windows. Select SCL protocol, 9600 baud, and address 0 or 126.
For the configuration menu contents, refer to the chapter User interface.

Input processing
The input is measured using an analog-to-digital converter. The reading is scaled to a weighing reading using the Lo and Hi setting in the configuration menu. When the input signal is 2.00
V, the display will indicate the Lo value, which is almost always set to 0. At 8.00 V input, the display will indicate the Hi value. The measurement unit can be freely selected (kg, ton, lbs...), and there is no need for the display unit to know it.
How many digits are displayed after the decimal point, is defined with the Dec setting in the configuration menu. The Dec setting can also be used to show fixed zeros, which is useful when displaying large readings (e.g. 10000 kg) and the last digits would otherwise be nervous.
The display can be slowed down with a digital 3rd degree lowpass filter.
The Dead setting can be used to round small readings to zero, or to prevent negative readings
Flt switch
The input card 2012KCI has one digital input.
Closing a switch connected to it will make the display to show "Flt" (except in Remote state).

Each 2 to 8 V input signal is scaled to weighing reading using the Lo, Hi 1, and Hi 2 settings in the configuration menu. Lo is almost always 0, and Hi
1 and Hi 2 correspond to the full scale weighs of the input channels. The unit of the scaling can be freely selected (kg, ton, lbs...) and there is no need for the display to know it. Then, negative readings are prevented (limited to 0), before summing up the readings. A tare value is subtracted. A new tare value can be stored using an external switch.
The 3rd order lowpass filter can be used to attenuate fluctuations and disturbances. The filter is bypassed a couple of seconds after power-up.

USER INTERFACE
This chapter describes how to use the small display and buttons inside the display unit to perform configuration. The contents of the configuration menu is described here too.
The small display inside the case and the large display always show the same contents, except that the large display may have less than 6 digits and then it shows dashes if the content does not fit.
The displays may be in the following states:
• Normal state – displaying the readings.
• Configuration state – changing the settings.
Normal state
After power-up, the unit is in the normal state, displaying the input readings according to the configuration.
The A3 indicator LED is lit when the external switch controlling the FLT or Tare function is active.
The tare function can be used also by pressing the
* key, and the tare value can be reset by pressing
* and > together (2211KCI only).
Configuration state
Entering
Press the * and ^ keys simultaneously two seconds in the normal state to enter the configuration state. When entered, the Conf led will light.
Navigating
Use the ^v keys to browse the menu. To see a configuration value and possibly edit it, push the > key. Return to the menu with the * key.
Editing
Integer values , such as the Dec setting, are adjusted with the ^v keys.
Floating point values , such as scaling and the lopass filter, are edited with ^v> keys: select digit to edit (blinking) with > and change it with ^v .
When the decimal point is blinking, it can be moved with ^v . The first digit can be replaced with a minus sign.
Exiting
When all settings are done, exit from the configuration menu with * key. Two options are shown: Save to keep the settings made, and Undo, to discard all changes. Select ^v Save or Undo and push > . (Or push * to get back to the menu.)
2011KCI configuration menu
Dec
Number of digits after the decimal point. E.g. with value of 1, the reading is displayed with one digit after the decimal point.
Lo
Hi
If the dec setting is negative, the corresponding number of last digits is rounded to zero.
Example: Dec= 2, the display will step 0, 100, 200...
Displayed reading at the minimum input signal (2 V). Almost always 0.
Displayed reading at the maximum input signal (8 V).

Dead>0: Display readings smaller than Dead are rounded to zero.
Dead=0: Negative readings are prevented.
Dead<0: Both positive and negative readings are displayed.
