Correct use
The EUCHNER handwheel is a universal pulse gen-
erator for manual shaft positioning.
The handwheel is primarily used for positioning NC-
driven machine tools during set-up.
Handwheels are used as part of an overall higher-
level control system.
Their use, installation and operation are permissible
only in conformity with these Operating Instruc-
tions.
Correct use includes compliance with the relevant
requirements for installation and operation, in
particular

EN 60204, electrical equipment of machines
 EN 12100, safety of machines, general design
principles
 EN ISO 13849-1, safety-related parts of control
systems
Safety precautions
EUCHNER HBA handwheels are permanently inte-
grated into the HBA hand-held pendant station and
in this state meet the EMC protection requirements
according to EN 61000-6-2 and EN 61000-6-4.
HBA handwheels must not be used for residential
applications, in business or commercial areas or
in small businesses.
Appropriate safety measures must be taken to
prevent a malfunction of the handwheel which
could cause danger to human beings or dam-
age to operating equipment.
Function
Depending on the type, 100 or 25 square wave puls-
es per revolution are available on the handwheel‘s
output to the user.
A second phase-shifted output allows the connected
control to detect the direction of movement.
The pulses are evaluated in the control.
The detent mechanism is magnetic and is therefore
totally wear-free.
Assembly
The handwheel is integrated permanently.
Do not open the
handwheels!
Do not hit the handwheels!
Do not use tools on the
handwheels!
Electrical connection
The handwheel is already permanently connected
within the hand-held pendant station HBA.
Service and inspection
EUCHNER handwheels require no maintenance.
Handwheels may only be repaired by the manu-
facturer.
To clean the handwheels, only use solvent-free clean-
ing agents and a soft cloth.
Disclaimer of liability
The company does not accept liability regarding the
following cases:
 if the unit is not used for its intended purpose
 if the safety instructions are not followed

if the units are tampered with
