PR 5220 Instrument Manual	Safety Information

1 Safety Information

1.1General 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.

1.2Intended 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.

1.3Initial 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 Sartorius sales or service organization must be notified.

1.4Before Commissioning

Visual inspection:

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

Sartorius

EN-7

Safety Information	PR 5220 Instrument Manual

1.4.1Installation

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

Caution!

Excessive heat may reduce the instrument lifetime!

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

1.4.2Electrostatically 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).

1.4.3Protective Earth

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

1.4.4Supply Voltage Connection

The supply voltage is 24V DC +10% / -15%.

Max. power consumption of

-PR 5220/00: 6.5 W

-PR 5220/01: 8.5 W

-PR 5220/04: 8.5 W

-PR 5220/06: 8.5 W

-PR 5220/07: 8.5 W

For connection to 230/115 V AC, an external power supply (e.g. Sartorius PR 1624/00 or Phoenix Mini Power) is required.

EN-8

Sartorius

PR 5220 Instrument Manual	Safety Information

1.4.5Failure 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).

1.4.6Fuse

This instrument does not have a replaceable 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.

1.4.7EMC-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 metallized connector housings.

- Establish equipotential 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 (e.g. Phoenix SK8-D)

Rail connection (e.g. Phoenix AB-SK 65D)

Mounting rail (35 mm)

Screen rail (e.g. Phoenix NLS-CU 3/10)

3 Installing the Instrument

•Before starting work, please read Chapter 1 and follow all instructions. Further procedures:

•Check the consignment: unpack the components specific to the application.

•Safety check: inspect all components for damage.

•Make sure the on-site installation is correct and complete including cables, e.g. power cable fuse protection, load cells, cable junction box, data cable, console/cabinet, etc.

•Follow the instructions for installation of the unit relating to application, safety, ventilation, sealing and environmental influences.

•Connect the cable from cable junction box or platform/load cell.

•If applicable: connect other data cables, network cables, etc.

•Connect the instrument to the supply voltage.

•Check the installation.

3.1Connections

The cable colors shown in this chapter are applicable to the Sartorius PR 62XX series load cells.

Before connecting other types, carefully follow the information related to the assignment of load cell/platform cable colors.

•The distance between the measuring cables and the power cables should be at least 1 m.

•The measuring cables should be laid in separate cable conduits or steel pipes connected to earth potential.

•Power cables should be crossed at right angles.

The load cell supply voltage is fixed to 12 V DC and protected against short circuit.

Load resistance of load cells ≥75 ¥, e.g. 8 load cells of 650 ¥ each.

3.1.6.4External Load Cell Supply

The internal load cell supply voltage of PR 5220 (V+, V-) is not connected.

The common line of the symmetrical external supply must be connected to the same terminal of PR 5220 as the shield of the load cell/extension cable.

Specification of external supply: ±6 V DC +5 %, -30 %; max ripple. 50 mVpp; max. asymmetry ±3 %.

An external supply voltage smaller than 8 V DC (±4 V DC) must be set under -[Weighingpoint]-[WP A]- [Calibration]-[Param]-[External supply].

3.1.6.5Connection via Intrinsically Safe Interface PR 1626/60

Connect the instrument to PR 1626/60 as described below. For additional connections, refer to the PR 1626/60 instrument manual. The internal load cell supply voltage of PR 5220 (V+, V-) is not connected.

Note:

If MX8 is closed in PR 1626/60, [below 8 V DC] must be set under
