2.2 Intended use
The interrogator RFH620 is an ISO/IEC-15693 compatible transponder printer/reader unit
for the close-up range (operating range of up to 16 cm), e. g., in a conveyor system.
The intended use of the interrogator results from the following description of the function:
• The interrogator is installed in a holder in a reading station.
• The interrogator transfers the reading data via the host interface to a superordinate
host computer for further processing.
• The interrogator is configured/operated using the SOPAS-ET configuration software
that runs on a standard client PC provided by the customer. In this connection, commu-
nication takes place via RS-232 or Ethernet.
• The Interrogator controls (locally), e. g., switches in the conveyor system via the digital
switching outputs.
Important Any warranty claims against SICK AG shall be deemed invalid in case changes are made to
the interrogator, e. g., opening the housing, this includes modifications during installation
and electrical installation or changes to the SICK software.
>The interrogator is only to be operated in ambient air temperature limit.
2.2.1 CE authorisation
The interrogator RFH620 fulfils the requirements of CE authorisation.
2.2.2 FCC authorisation
The interrogator RFH620 is in accordance with part 15 of FCC guidelines.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
• This device may not cause harmful interference, and
• this device must accept any interference received, including interference that may cau-
se undesired operation.
Any changes or modifications not expressly approved by the party responsible for compli-
ance could void the user's authority to operate this equipment.

>Read the general safety precautions thoroughly and observe them during all operations
on the interrogator. Also observe the warning notices in each chapter of this document
before the standard operating procedures.
Electrical installation work
Important >Electrical installation must be performed by qualified staff only.
>Connect or release current linkages only under de-energised conditions.
>Wire cross sections and their correct shields have to be selected and implemented ac-
cording to valid engineering standards.
Risk of injuries due to electrical current!
The optional power supply module CMP400/CMP490 is connected to the power supply
(100 ... 250 V AC/50 ... 60 Hz) in the connection module CDM420.
>Observe current safety regulations when working with electrical equipment.

2.4 Quick stop and quick restart
The interrogator can be switched on or off using the main switch for connection modules
CDB620 or CDM420 respectively.
2.4.1 Switching off the interrogator
>Switch off the power supply to the interrogator (via the connection module)
- or -
Unplug the 15-pole D-Sub-HD connector of the interrogator´s connection cable from
the connection module.
When the interrogator is switched off, the following data are lost:
• Application-specific parameter sets in the interrogator that were only saved temporarily
in the device
• The last reading result of the interrogator
• Daily operating hours counter of the interrogator
2.4.2 Switching the interrogator back on
>Switch the power supply to the interrogator (via the connection module) back on
- or -
Re-connect the 15-pole D-Sub-HD connector of the interrogator´s connection cable to
the connection module.
The interrogator starts up using the most recent permanently saved configuration. The
daily operating hours counter is reset.
2.5 Environmental information
The interrogator has been constructed with minimum environmental pollution in mind. Ex-
cluding the housing, the interrogator does not contain any materials made of silicone.
2.5.1 Energy requirement
The interrogator serial RFH620 consumes the following energy:
• Typical 5 W in 10 ... 30 V DC (in unwired switching outputs)
2.5.2 Dispose of the device after decommissioning
Currently, SICK AG will not accept the return of any devices which can no longer be operated
or repaired.
>Inoperable or irreparable devices must be disposed of in an environmentally friendly
manner and in accordance with valid country-specific waste disposal guidelines.
The design of the interrogator allows for its separation as recyclable secondary raw materi-
als and hazardous waste (electronic scrap).

Optimising the reading conditions
If no transponder is displayed or if you wish to increase the RSSI value, the reading can be
repeated by taking the following measures:
1. Correct or optimise the parameter values, where necessary, via the SOPAS-ET configu-
ration software.
2. In order to optimise the RSSI value, reduce the distance between the interrogator and
the transponder.
Reading/writing the user data of the transponder
The user data of a transponder can be read/written via the register tab TAG ACCESS of the
SOPAS-ET configuration software:
Important When accessing, the transponder must be located in the reading area of the interrogator.
>Select a transponder from the list on the register tab QUICKSTART and click on ACCESS.
The register tab TAG ACCESS opens.
The user data of the transponder are read and displayed.
