output can be connected to a control system, to a PLC for example, as a monitoring
output.
The HS3A can be reset via the RST input. To reset, apply 24V DC for at least 3
seconds. When not using the RST input, connect the RST input to 0V.

When using two or more HS3A in series• A maximum of 20 can be connected in series.
• Pay attention to the contact resistance at the connection points.
The HS3A switches can be connected in series using plug connection cables andY-branch connectors as shown in the figure below (Note). When any of the HS3A
switches detects that the safety guard is open, or when a failure has occurredon any of the switches, the system turns off the machine. However, the external
control system cannot detect which safety guard is open or where a failure has
occurred.
The HS3A can be reset via the RST input. To reset, apply 24V DC for at least 3
seconds. When not using the RST input, connect the RST input to 0V.

· Use the actuator mounting screws supplied with the HS3A. When using
other screws, use stainless steel or nonmetallic screws. Otherwise
operating distance may be affected.

Operation Distance and Response Time• When installing the HS3A, ensure the safety of the door opening area by
paying attention to the operation distance (Table 1) and response time (Table2) shown below.

• Do no use the monitor output (OUT) as a safety output.
• The HS3A supplies +24V to dual safety outputs while in turn-on state. Inputsof the connected safety controller and safety PLC must be positive-switching.
• All electrical connections must either be isolated from the main power supply
by a safety transformer according to EN IEC 61558-2-6 with limited output
voltage in the event of a fault, or by other equivalent isolation measures.
• Use a power supply rated for Class 2 circuits or of equivalent function.
• All electrical outputs, including monitor outputs, must have an adequate
protective circuit for inductive loads. Protecting of the outputs using a freewheeling diode is recommended.
• Power devices which can cause interference must be installed away fromthe input and output circuits for signal processing. Provide sufficient distance
between the wirings of safety circuits and power circuits.
• Use the HS3A with the proprietary actuator (HS9Z-ZH31) only, and do not use
any other actuator.
• Provide the power supply with fuse protection depending on the numberof sensor heads and the required output current. For details, refer to “Fuseprotection for power supply” in system manual B-1223.
• The HS3A switch generates its own pulses (up to 1 ms) on the safety outputs
OA and OB for confirming the safety function. Use a downstream control
system that tolerates these test pulses. When using a system with pulsing
function, defeat the pulsing function. Note that pulse is generated even when
the safety output is off.
• When installing the HS3A switches adjacently, provide at least 80 mm
intervals to avoid mutual interference.

Note 1: When the off-center displacement of the interlock switch (sensor head) and actuatoris 0 mm.
Note 2: When surface-mounted on aluminum. When using by embedding in metal,
pay attention to the operation distance affected by the metal. In non-metallic
environment, the typical turn-on distance increases to 30mm.

24V DCVUB

Explosion Proof• Do not store the HS3A in a dusty, humid, organic-gas atmosphere, or areas
subject to direct sunlight.
• Regardless of door types, do not use the HS3A as a door stop. Install amechanical door stop on the edge of the door to protect the interlock switch
against excessive force.
• Do not apply excessive force to the HS3A. A shock to the door exceeding
300 m/s2 may cause a failure to the switch (shock resistance 300 m/s2)• Be sure to use the HS3A in combination with the proper accessories andconnection cable. Failure to do so will result in the damage or failure of theswitch.
• The HS3A may only be installed and operated by personnel who are skilled/familiar with the followings:· O peration of safety products· R elevant EMC standards· R elevant regulations and standards of safety and health· D escriptions in instruction sheet and system manual• Check the following daily in order to ensure correct operation and long service

assessment before operation.
• Do not disassemble, modify, or repair the HS3A. Also do not disable the safetyfunction of the interlock switch, otherwise failure or accident will occur.
• In order to avoid electric shocks or fire, turn power off to the HS3A before
installation, removal, wiring, maintenance, or inspection.

Note: In actual system or equipment, various factors such as hazard type,safeguarding measure, and danger level depending on operation modes
need to be taken into consideration for risk assessment, in order toreduce the risk to an acceptable level. Therefore, safety category must be
evaluated on the entire safety related system.
