Section 1: Safety Information

1 Safety Information

The instrument was in perfect condition with regard to safety features when it left
the factory. To maintain this condition and to ensure safe operation, the operator
must follow the instructions and observe the warnings in this manual.

1.1 Intended Use

The instrument is intended for use as an indicator for weighing functions. Product operation,
commissioning and maintenance must be performed by trained and qualified personnel who are
aware of and able to deal with the related hazards and take suitable measures for self-protection.
The instrument reflects the state of the art. The manufacturer does not accept any liability for
damage caused by other system components or due to incorrect use of the product.

1.2 Initial Inspection

Check the content of the consignment for completeness and inspect it visually for signs of damage
that may have occurred during transport. If there are grounds for rejection of the goods, a claim must
be filed with the carrier immediately and the sales or service organization must be notified.

1.3 Before Commissioning

Visual inspection:
Before commissioning and after and storage or transport, inspect the instrument
visually for signs of mechanical damage.

1.3.1 Installation

The instrument is designed for mounting on standard rails (35 mm, acc. to DIN 46277).

When mounting on the rail, please make sure that the distance from other
instruments left and right of the module is at least 20 mm.

1.3.2 Electrostatically Sensitive Components

This instrument contains electrostatically sensitive components. For this reason, an equipotential
bonding conductor must be connected when working on the open instrument (antistatic protection).

05/11 9 51209 Revision 2

Section 1: Safety Information

1.3.3 Protective Earth

Connection to protective earth must be performed via the mounting rail.

1.3.4 Supply Voltage Connection

The supply voltage is 24V DC +10% / -15%.
Max. power consumption of /00 version: 6.5 W; /01 and /04
version: 8.5 W
For connection to 230 / 115 V AC, an external power supply
(e.g. PR 1624/00 or Phoenix Mini Power) is required.

1.3.5 Failure and Excessive Stress

If there is any reason to assume that safe operation of the instrument is no longer ensured, shut it
down and make sure it cannot be used. Safe operation is no longer ensured if any of the following
is true:

- The instrument is physically damaged

- The instrument does not function

- The instrument has been subjected to stresses beyond the tolerance limits (e.g., during storage
or transport).

1.3.6 Fuse

This instrument does not have a replacable fuse. The load cell supply voltage is protected against
short circuit. In case of failure of the load cell supply voltage, disconnect the instrument from the
supply voltage, determine the cause and take remedial measures. Subsequently, the supply voltage
can be switched on again.

1.3.7 EMC-Compliant Installation

Use only screened data cables

--

Connect screens on both ends with ground

--

Keep unscreened cable ends short
Connect screen rail to cabinet / housing with

-

low impedance

-

Use metal or metalized connector housings
Establish equi-potential bonding between
instruments / system modules (Mandatory for

-

Ex-applications)

-

Use standard reference potential

-

Connect mounting rail to protective earth
Install measure and data cables separately
from power cables

Screen clamp (z.B. Phoenix SK8-D)

Rail connection (z.B. Phoenix AB-SK 65D)
Mounting rail (34mm)
Screen rail (e.g. Phoenix NLS-CU 3/10)

4.1 Status Indicator LEDs

The instrument has 5 green LEDs for indication of the operating or error status.
Power supply, bus connection

* The LED for the bus activity (PR 5220/01 a. PR 5220/04) is lit as soon as there is a connection. It
continues being lit, also when there is no communication, or when the physical connection is cut.

5 Commissioning

The meaning of indicator LEDs and the operating concept are described in Chapter 4.

5.1 Data Backup/Power Failure

The calibration data and parameters as well as all configuration and interface data are stored in a
non-volatile (EAROM) memory. Unauthorized data changing can be prevented by an access code.
Additional write protection is provided for calibration data and parameters (CAL switch, see
Chapter 5.1.1).

5.1.1 CAL Switch

The CAL switch protects the calibration data / parameters against unauthorized access.
When the CAL switch is in 'open' position, the calibration data and parameters can be changed

using the PC program or via the Profibus connection.
With the CAL switch in the 'closed' position, the calibration data (e.g. dead load, Span) and
Parameters (e.g. measure time, zero tracking etc.) cannot be changed.

The CAL switch is located under a cover that can be opened by
means of a knife.

For ’legal-for-trade’ applications, set the CAL switch (4) to the
left position and seal the cover.

5.1.2 Factory Settings

Calibration data <default> Calibration data <default>
Full scale (Max) <3000> <Kg> Measure time (M) <320>ms
Scale interval <1> Measuring rate <160>ms

* Parameter W&M must be set to 'on' or 'off' prior to input of the calibration data, see Chapter

5.4.20.

5.2 Switching on the Instrument

The instrument can be put into operation and calibrated using a PC with the VNC program (on the
CD packed with the instrument), an Internet Browser or the ConfigureIt program.

5.2.1 Resetting the Instrument, Activating 'DHCP'

The instrument can be reset using a pin with a diameter of 1.0 mm
(e.g. paper clip).

By actuating during approx. 1 second, the program is re-started.
When actuating during approx. 3 seonds, 'DHCP' is activated in the
instrument (independent of the previous settings). This ensures that a
valid address for identification of the instrument in the network can be
assigned to the instrument by a server.

05/11 29 51209 Revision 2

5.2.2 Searching the Instrument in the Network Using 'IndicatorBrowser'

The address can be determined using the 'IndicatorBrowser' (in a directory on the CD-ROM packed
with the instrument) program.

Install and start the 'IndicatorBrowser'.

When the instrument is connected to a network, it is
“default” in the DHCP mode, i.e. an address is
assigned to it by the server. This address, e.g.

172.24.21.85, can be determined using the
‘IndicatorBrowser’ program.

Section 5: Commissioning

5.3 Operation Using a PC

5.3.1 Operation Using the VNC Program

VNC stands for 'virtual network computing' and is a program for remote operation of computers.
The program distinguishes between the VNC server and VNC client (viewer). The server program is
part of the instrument software. The client program (viewer) must be installed and executed on the
PC to be used for operating the instrument.

For direct operation using the VNC program, the IP
address (extended by :1) must be specified when you
run the program, e.g. 172.24.21.85:1.

The address range of the
controlling PC can be
limited in the instrument;
see Chapter 5.6.5.
The operator interface of
the VNC program appears:

05/11 30 51209 Revision 2

5.3.2 Operation Using Internet Browser

With the Internet browser, the IP address must be filled in.
Example:

For instrument operation using the VNC program without additional installation of VNC, see Chapter

5.3.1 .
