Hengstler RA 58-P Installation Instructions

Installation instructions
Absolute Shaft Encoders RA 58-P/RA 59-P,
Interbus (K3)
Item No. 2 543 043
Introduction
These installation instructions are provided for the connection and starting
procedure of your shaft encoder.
For further informations see user guide:
• RA 58-P/RA 59-P with Interbus (K3): Item No. 2 543 003
General aspects
The shaft encoder of the type RA 58-P/RA 59-P can be programmed via the
Interbus. Due to this function the encoder may be used universally; thus the
range of variants as well as the storage will be reduced for the customer.
A lot of calculating time and expense on the host system will be saved by
data processing within the encoder.
The RA 58-P/RA 59-P is equipped with an EEPROM for remanent storage of
the parameters. When the device is turned on the parameters are transferred
automatically to the memory.
This sign marks paragraphs particularly to be observed to assure
proper use and to avoid risks.

Safety and Operating Instructions

• The absolute shaft encoders of the type RA 58-P/RA 59-P model series are
quality products manufactured in accordance with established electrical
engineering standards.
The units have been delivered from the factory in perfect conformance to
safety regulations.
To maintain this condition and to ensure trouble-free operation, please ob-
serve the technical specifications of this document.
• Installation and mounting may only be performed by an electrotechnical
expert!
• The units may only be operated within the limits specified by the technical
data.
• Maximum operating voltages must not be exceeded!
The units are designed complying with DIN EN 61010-part 1, protection class III.
To prevent dangerous structure-borne currents, the equipment has to be run
on safety extra-low voltage (SELV) and must be in an area of equipotential
bonding.
Please use an external fuse for protection (see Electrical Data).
• Fields of application: industrial processes and controls.
Overvoltage at the connecting terminals must be limited to overvoltage-
class-II values.
• Please avoid shocks to the housing – especially to the encoder shaft – and
axial or radial overload to the encoder shaft.
• Maximum accuracy and durability of our shaft encoders are only granted
when using suitable couplings.
• The high-quality EMC-specifications are only valid together with standard-
type cables and plugs. When using screened cables, the screen must broadly
be connected with ground on both ends. Likewise, the voltage-supply cables
should entirely be screened. If this is not possible you will have to take
appropriate filtering measures.
• Installation environment and wiring are influential on the encoder's EMC:
Thus the installer must secure EMC of the whole facility (device).
• In electrostaticly threatened areas please take care for neat ESD-protection
of plug and connecting cable during installation work.
• Specified maximum shaft loads are only given under restrictions:
10
– Full bearing life of 1 x 10 revolutions (typ.) will be reached at 35% of
full rated shaft load
8
– a bearing life of 1 x 10 revolutions (typ.) will be reached at 100% of full
rated shaft load.
