Operating instructions for hand-held pendant stations HBE and HBL
These operating instructions are valid only in
connection with the data sheet of the rele-
vant hand-held pendant station and with the
operating instructions of the relevant handw-
heel!
See rating plate of hand-held pendant station.
Safety precautions
EUCHNER hand-held pendant stations HBE and
HBL meet the EMC protection requirements
according to EN 61000-6-2 and EN 61000-6-4.
EUCHNER handwheels must not be used for
residential applications, in business or commercial
areas or in small businesses.
The operator of the overall higher-level system is
responsible for conformity with the national and
international safety and accident prevention
regulations applicable to the special application.
When designing machines and using handwheels,
the national and international safety and accident
prevention regulations specific to the application
must be observed, e.g.:
EN 60204, electrical equipment of machines
EN 292, safety of machines, general design
principles
EN 954, safety-related parts of control systems
Voltage applied to hand-held pendant stations
must not exceed 30 V.
Appropriate safety measures must be taken
to prevent a malfunction of the handwheel
which could cause danger to human beings or
damage to operating equipment.
No commands that may lead to potentially
hazardous conditions may be initiated by
enabling switches alone. In such case, a se-
cond, deliberate start command is required.
Every person present in the danger area must
carry his/her own enabling switch on his/her
person.
Risk of injury is present when handling the
hand-held pendant station due to the strong
attraction of the mounting.
Keep heart pacemakers, magnetic data carri-
ers (data loss) and electrical and electronic
devices at a suitable distance.
Correct use
Machine installations in manual mode can be
operated with hand-held pendant stations.
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 instructions.
Incorrect use
Hand-held pendant stations on their own must not
be used as safety components for avoiding
hazardous states in a machine installation.
General function
Hand-held pendant stations make it possible to
operate a machine installation, for instance, in
manual mode.
Function of individual components
The hand-held pendant station may consist of the
following components:
Handwheel
EMERGENCY-STOP device
Enabling switches
Selector switches
Key-operated rotary switches
Pushbuttons
Handwheel
The electronic handwheel is a universal pulse
generator for manual shaft positioning.
An output of 100 or 25 square-wave pulses per
revolution is available. A second phase-shifted
output allows the connected controller to detect
the direction of movement.
The pulses are evaluated in the controller.
For technical data, see Handwheel HKD operating
instructions.
EMERGENCY-STOP device
The EMERGENCY-STOP device is designed to be ma-
nipulation-proof in accordance with IEC 60947-5-1/
EN 418.
Enabling switches, selector switches, key-
operated rotary switches, pushbuttons
These components are used to transfer additional
information to the higher-level machine controller.
Assembly
Hand-held pendant stations are not used exclusively
at a single site. The stations can be stored using a
mounting magnet on the rear of the device or a
holder.
Electrical connection
Electrical connection may only be performed
by authorised personnel trained in EMC with
the machine switched off and in a de-
energised state.
The machine must be safeguarded
against reactivation.
Incorrect connection may cause damage
to the components of the hand-held pen-
dant station!
Observe electrical characteristics and the pin
assignments!
The pin assignment can be found in the data
sheet.
Always shield connecting leads.
Make sure that the lead’s connection is EMC-
compatible.
Ground the shield at the end of the lead at a cen-
tral grounding point, e.g. in the distribution board
or in the control cabinet, over a large surface,
with low resistance and with low inductance.
Original connecting leads must not be shortened.
Given an extension or other modification to the
connection cable, the operator must ensure that
the valid EMC protection requirements are
observed.
Do not install connecting leads in the immediate
vicinity of interference sources.
Authorization according to:
Operation with UL-class 2 power supply only.
Connection leads of hand-held pendant stations
installed at the application site must be separated
from all movable and permanently installed leads
and non-insulated active parts of other installation
parts which operate with a voltage of over 150 V,
in such a way that a constant clearance of 50.8
mm is observed. This does not apply if the movable
leads are equipped with suitable insulation materials
which possess an identical voltage stability to the
other relevant installation parts or higher.
Service and inspection
EUCHNER handwheels require no maintenance.
Handwheels may only be repaired by the manufac-
turer.
To clean the handwheels, only use solvent-free cle-
aning agents and a soft cloth.
Disclaimer of liability
The company is unable to accept liability in the
following cases:
if instructions are not followed
if the safety instructions are not followed
if the units are electrically connected by
unauthorised personnel
if any external intervention occurs
Do not open hand-held
pendant stations!
Do not throw or drop the
hand-held pendant stati-
ons!
