  • Page 66: System Installation

    WARNING: Read this Section Carefully Before Installing the System The Banner Safety Controller is a control device that is intended to be used in conjunction with a machine safeguarding device. Its ability to perform this function depends upon the appropriateness of the application and upon the Safety Controller's proper mechanical and electrical installation and interfacing to the machine to be guarded.

  • Page 67: Safety Input Devices

    NOTE: Follow the device manufacturer's installation, operation, and maintenance instructions and all relevant regulations. If there are any questions about the device(s) that are connected to the Safety Controller, contact Banner Engineering for assistance. Figure 57. Input and output terminal locations WARNING: Input Device and Safety Integrity The Safety Controller can monitor many different safety input devices.

  • Page 68: Safety Circuit Integrity And Iso 13849-1 Safety Circuit Principles

    XS/SC26-2 Safety Controller 6.3.1 Safety Circuit Integrity and ISO 13849-1 Safety Circuit Principles Safety circuits involve the safety-related functions of a machine that minimize the level of risk of harm. These safety- related functions can prevent initiation, or they can stop or remove a hazard. The failure of a safety-related function or its associated safety circuit usually results in an increased risk of harm.

  • Page 69: Safety Input Device Properties

    XS/SC26-2 Safety Controller Fault Exclusion An important concept within the requirements of ISO 13849-1 is the probability of the occurrence of a failure, which can be reduced using a technique termed "fault exclusion." The rationale assumes that the possibility of certain well-defined failure(s) can be reduced via design, installation, or technical improbability to a point where the resulting fault(s) can be, for the most part, disregarded—that is, "excluded"...

  • Page 72: Safety Circuit Integrity Levels

    The application requirements for safeguarding devices vary for the level of control reliability or safety category per ISO 13849-1 (EN954-1). While Banner Engineering always recommends the highest level of safety in any application, the user is responsible to safely install, operate, and maintain each safety system and comply with all relevant laws and regulations.

  • Page 73: Enabling Device

    XS/SC26-2 Safety Controller Rope pull emergency stop switches have many of the same requirements as emergency stop push buttons, such as positive (direct) opening operation, as described by IEC 60947-5-1. See Emergency Stop Push Buttons on page 72 for additional information.

  • Page 74: Interlocked Guard Or Gate

    XS/SC26-2 Safety Controller Protective (Safety) Stop Requirements The required safety circuit integrity level is determined by a risk assessment and indicates the level of control performance that is acceptable, for example, category 4, Control Reliability (see Safety Circuit Integrity and ISO 13849-1 Safety Circuit Principles on page 68).

  • Page 75: Two-Hand Control

    XS/SC26-2 Safety Controller Optical safety devices must be placed at an appropriate safety distance (minimum distance), according to the application standards. Refer to the applicable standards and to manufacturer documentation specific to your device for the appropriate calculations. The response time of the Safety Controller outputs to each safety input is provided on the Configuration Summary view in the PC Interface.
  • Page 76 T h is usually insignificant for purely mechanical switches. However, T h should be considered for safety distance calculation when using electronic or electromechanical (powered) hand controls. For Banner Self-checking Touch Buttons (STBs) the response time is 0.02 seconds the maximum time (in seconds) the machine takes to cease all motion after it has been tripped. For full revolution clutch presses with only one engaging point, T m is equal to the time necessary for one and one-half revolutions of the crankshaft.

  • Page 77: Safety Mat

    Safety Mat application requirements vary for the level of control reliability or category as described by ISO 13849-1 (EN 954-1). While Banner Engineering always recommends the highest level of safety in any application, the user is responsible to safely install, operate, and maintain each safety system per the manufacturer's recommendations and comply with all relevant laws and regulations.
  • Page 78 XS/SC26-2 Safety Controller The environmental rating of the sensor must meet a minimum of IP54. When the sensor is specified for immersion in water, the sensor’s minimum enclosure level must be IP67. The interconnect cabling may require special attention. A wicking action may result in the ingress of liquid into the mat, possibly causing a loss of sensor sensitivity.
  • Page 79 XS/SC26-2 Safety Controller Safety Mat Safety Distance (Minimum Distance) As a stand-alone safeguard, the safety mat must be installed at a safety distance (minimum distance) so that the exterior edge of the sensing surface is at or beyond that distance, unless it is solely used to prevent...

    XS/SC26-2 Safety Controller 6.4.12 Adjustable Valve Monitoring (AVM) Function The Adjustable Valve (Device) Monitoring (AVM) function is similar in function to One-Channel External Device Monitoring (1-channel EDM, see External Device Monitoring (EDM) on page 90). The AVM function monitors the state of the device(s) that are controlled by the safety output to which the function is mapped.

  • Page 83: Non-Safety Input Devices

    XS/SC26-2 Safety Controller CAUTION: Adjustable Valve Monitoring (AVM) Operation When an input is configured with automatic reset logic and is quickly cycled (from Run to Stop to Run), the Safety Output(s) will not turn ON until the AVM input is satisfied. This could result in an On- Delay up to the configured AVM monitoring time.
