HE1B Basic Three-position Enabling Switches
• The enabling switches have been designed for industrial purposes.
Use for residential, commercial, or lighting purposes may cause
unwanted electromagnetic disturbances in which case the user may
be required to take adequate mitigation measures. (IEC60947-1,
Clause 5.3)
• In order to avoid electric shock or re, turn the power off before in-
stallation, removal, wiring, maintenance, or inspection of the enabling
switch.
• When using the enabling switch in a safety related part of a control
system, use the enabling switch properly in accordance with the
safety standards and regulations of the actual machine, system,
and application, of the country or region where the enabling switch
is used. Also, perform a risk assessment before using the enabling
switch.
• Do not disable the safety function of the enabling switch by using
tape, elastic band, or by disguring the rubber boot, otherwise the
loss of enabling switch function may cause serious accidents.
• Perform a risk assessment in actual applications as strong force may
be applied to the switch when depressed to position 3.
• Perform a risk assessment for the shape and structure of the part
where the enabling switch is installed, to prevent unintended opera-
tion of the enabling switch. For example, an enabling switch protrud-
ing from the teach pendant may result in an unintended operation of
the enabling switch.
• Strong force may be applied to a 3-position enabling switch when
pressed to position 3. Provide sufcient strength to the part where
3-position enabling switches will be installed.
• Use wires of the proper size to meet voltage and current require-
ments, and solder the wires correctly according to the wiring instruc-
tion described below. If soldering is incomplete, the wire may heat
during operation, causing a re hazard.
• Do not apply excessive force to the enabling switch.
• Follow the wiring instructions mentioned in the instruction manual.
Safety Precautions
Instructions
Operating Instructions
• The enabling switch permits machine operation only while the
enabling switch is manually operated for robot teaching or other
purposes in hazardous areas. Make sure that the control system is
designed to activate the machine only when the enabling switch is at
position 2 (2.2mm) operating travel.
• To prevent malfunction of the button, provision for protection is
required.
Installation Instructions
• Provide sufcient strength to the mounting panel. Insufcient strength
of the mounting panel or excessive operating force may damage the
enabling switch, resulting in electric shock or re.
Wiring Instructions
• Applicable wire size: 0.5 mm
2
maximum × 1 pc.
• Solder the terminal at a temperature of 310 to 350°C within 3 sec-
onds using a soldering iron. Sn-Ag-Cu type is recommended when
using lead-free solder. Do not use ow or dip soldering.
• When soldering, take care not to touch the enabling switch with
the soldering iron. Also ensure that no tensile force is applied to the
terminal. Do not bend the terminal or apply excessive force to the
terminal.
• Use non-corrosive liquid rosin as soldering ux.
