DESCRIPTIVE ANNEX
Characteristics of the instrument:

automatic weighing instruments.
The above designations may have the prefix “JOLLY” and may be followed by alphanumeric
characters (e.g. JOLLY WINOXL).

used for direct sales to the public.
Main features:
− Metal or plastic enclosure
− LCD or LED display
− Operator’s keypad with 4 to 62 keys
− Optional secondary display
− Optional level indicator based on a digital input
− Connection through shunt-diode safety barrier (EEx version)
Devices:
− Initial zero setting device (< 20% of Max)
− Semi-automatic zero setting device (< 4% of Max)
− Zero tracking device (< 4% of Max)
− Semi-automatic tare weighing or balancing
− Preset tare (not for direct sales for public)
− Display check at power-up
− Alibi memory
− Gravity compensation
− Extended indication (not available to the user)
− Printing
− Price computing
− Stable weight indicator
− Weighing unstable samples (optional)
− Real time clock
− Operator information messages
Price computing models:
The WDOS (special version), WDESK, WINOX and WTAB models can operate as a price
computing instruments with a price look-up table. Selection of product and price are per-
formed via a digital input or serial interface.

Load cell:
Any compatible load cell(s) may be used providing the following conditions are met:
− There is a respective OIML Certificate of Conformity (R60) issued for the load cell.
− The certificate contains the load cell types and the necessary load cell data required
for the manufacturer’s declaration of compatibility of modules (R76-1 (2006), Annex
F), and any particular installation requirements. A load cell marked NH is allowed
only if humidity testing to R76 has been conducted on this load cell.
− The compatibility of the load cells and indicator is established by the manufacturer
by means of the compatibility of modules calculation at the time of verification.
− The load cell transmission must conform to one of the examples shown in OIML
R60: 2017 – Annex E.
The instruments may be connected to the following digital load cells:

Interfaces:
The instruments may have any of the following protected interface type:
− Load cell 4-wire or 6-wire shielded connection
− RS232C
− RS485
− USB
− Modbus RTU, Profibus, DeviceNet and CANopen Ethernet TCP/IP, Ethernet/IP,
Modbus/TCP, Profinet IO, EtherCAT, POWERLINK, SERCOSIII, CC-link, CC-link IE
and IO-link
− Digital output / Digital input
− Analogue input / Analogue output
− Wireless
Software:
The software version number is displayed at power up.
The version format is xx.yy.zz, where xx is the legally relevant version number, with yy and
zz the major and minor version numbers reflecting non-legally relevant changes.
The software version for standard indicators is 01.yy.zz, where yy.zz shall be 00.46 or
higher. The software version for price computing indicators is 01.yy.zz, where yy.zz shall be
03.04 or higher.
Sealing:
The calibration and legally relevant parameters are protected via physical or software means.
The indicators have an event counter, which increments each time the legally relevant
parameters (calibration and configuration) are changed. The value of the event counter can
be displayed in the ‘Menu’ under ‘Info’, and must be written on the data plate.
For the WLIGHT indicator the legally relevant parameters (calibration and configuration) can
be accessed by pressing a button on the rear of the indicator. This button is protected by
tamper evident seals.
Access to the electronics, jumper, load cell connections, junction box, and peripheral interfaces
is prevented via tamper evident labels or by the use of wire and seals.
Alternatively, the electonics may be secured via a tamper evident label on the cover protecting
the analogue circuits, swapping of the electonics is then prevented via a common indicator
serial number (affixed on on the data plate and displayed from the the non-erasable memory).
Alternatively, the indicator and load receptor with load cell made be secured via common serial
numbers (indicator serial number on platform or load cell serial number on indicator).
This is not necessary for the W200IP64, W200IP67, WDESK, WDESKLIGHT, WINOX,
W200BOX, W200BOXEC and ADPEW200 models with hardwired load cell connection,
provided the indicator enclosure is sealed.
