PR 5220 Instrument Manual Safety Information

1 Safety Information

1.1 General 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.

1.2 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.

1.3 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 Sartorius sales or service organization must be notified.

1.4 Before 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
The supply voltage is 24V DC +10% / -15%.
PR 5220 Instrument Manual

1.4.1 Installation

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.

1.4.2 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).

1.4.3 Protective Earth

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

1.4.4 Supply Voltage Connection

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
EN-8 Sartorius
(e.g. Sartorius PR 1624/00 or Phoenix Mini Power) is required.
PR 5220 Instrument Manual Safety Information
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)

1.4.5 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).

1.4.6 Fuse

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.

1.4.7 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 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.

3.1.6 Load Cell Connection

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.

3.1.6.4 External 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 [Calibration]-[Param]-[External supply].
