  • Page 3: Correct Use

    Part 1: General requirements HS3A is only allowed to be operated in conjunction with the intended HS9Z actuators from IDEC and the related connection components from IDEC. On the use of different actuators or other connection components, IDEC pro- vides no warranty for safe function.
  • Page 4 System Manual HS3A-H21M4 Important! The user is responsible for the proper integration of the device into a safe overall system. For this purpose, the overall system must be validated, e.g. in accordance with EN ISO 13849-2. Correct use requires observing the permissible operating parameters (see Technical data on page 24).
  • Page 5: Description Of The Safety Function

    System Manual HS3A-H21M4 Description of the safety function HS3A features the following safety functions: Monitoring of the safety guard position (interlocking device according to EN ISO 14119) Safety function: The safety outputs are switched off when the safety guard is open (see Switching states on page 8). Safety characteristics: category, Performance Level, PFH (see Technical data on page 24).
  • Page 6 Prior to use read the operating instructions and the system manuals, and keep these in a safe place. Ensure the operating instructions and the system man- uals are always available during mounting, setup and servicing. IDEC cannot provide any warranty in relation to the readability of the CD-ROM supplied for the storage period required.
  • Page 7: Function

    System Manual HS3A-H21M4 Function HS3A monitors the position of movable safety guards. The safety outputs are switched on/off when the actuator moves into/out of the operating distance. HS3A complies with the following safety requirements: Category 4, PL e according to EN ISO 13849-1. Redundant design of the circuit in the unit with self-monitoring.

  • Page 9: Changing The Approach Direction

    System Manual HS3A-H21M4 Changing the approach direction Caution! Risk of damage to equipment as a result of trapped cables. Make sure that the cables are not trapped or torn off when the approach direction is changed. Make sure that the flat seal is not trapped and that the profile seal is properly positioned in its guide, otherwise the sealing function is no longer ensured.
  • Page 10: Installation

    System Manual HS3A-H21M4 Installation Caution! Safety switches must not be bypassed, turned away, removed or otherwise rendered ineffective. Observe EN ISO 14119:2013, section 7, for information about reducing the possibilities for bypassing an interlocking device. Caution! Risk of damage to device and malfunctions as a result of incorrect installation. HS3A and actuators must not be used as an end stop.
  • Page 11 System Manual HS3A-H21M4 Actuator and HS3A must be fitted so that - the front faces are at the minimum switch-on distance 0.8 x S or closer when the safety guard is closed (see section Operating distances and Typical operating distance on page 28). To avoid entering the area of possible side lobes, a minimum distance is to be maintained in case of a side approach direction.
  • Page 12: Electrical Connection

    System Manual HS3A-H21M4 Electrical Connection The following connection options are available: Separate operation Series connection with Y-distributors from IDEC Series connection, e.g. with wiring in the control cabinet Warning! In case of an error, loss of the safety function through incorrect connection.
  • Page 13: Notes About Ul, C-Ul

    System Manual HS3A-H21M4 Notes about UL, c-UL Important! For use and operation as per the UL, c-UL requirements , a power supply with the feature “for use in class 2 circuits” must be used. Alternative solutions must comply with the following requirements: a) Electrically isolated power supply unit with a max.
  • Page 14: Requirements For Connection Cables

    Use connection components and connection cables from IDEC On the usage of other connection components, the requirements in the fol- lowing table apply. IDEC provides no warranty for safe function in case of failure to comply with these requirements. Observe the following requirements for the connection cables:...
  • Page 15: Maximum Cable Lengths

    System Manual HS3A-H21M4 Maximum cable lengths Switch chains are permitted up to a maximum overall cable length of 200 m taking into account the voltage drop as a result of the cable resistance (see table below with example data and case example). =200 m = 24V DC -20% = 24V DC -10%...
  • Page 16 System Manual HS3A-H21M4 Determining cable lengths using the example table (see table 2) Example: 6 switches are to be used in series. Cabling with a length of 40 m is routed from a safety relay in the control cabinet to the last switch (#6). Cables with a length of 20 m each are connected between the individual HS3A safety switches.

    System Manual HS3A-H21M4 Connection of a single HS3A If a single HS3A is used, connect the device as shown in Figure 7. The OUT output can be connected routed to a control system as a monitoring output. The switch can be reset via the RST input. To do this, a voltage of 24 V DC is applied to the RST input for at least 3 seconds.
  • Page 19: Connection Of Several Hs3A In A Switch Chain

    System Manual HS3A-H21M4 Connection of several HS3A in a switch chain Important! A HS3A switch chain may contain a maximum of 20 safety switches. The switches are connected in series using plug connectors and Y-distributors. If a safety guard is opened or if a fault occurs on one of the switches, the system shuts down the machine.
