The door interrupt system must be installed by qualified personnel who are properly trained in the installation and usage of the FYQLA1-140R-3 product. These persons must have access to all instructions and knowledge of all required safety requirements regarding the application of such devices and machinery equipment.
Features The FYQLA1-140R-3 is a category 3 PL d( ISO 13849-1:2015) logic amplifier. The basic features of the FYQLA1-140R-3 include inputs for up to six individual two-channel switches for monitoring door access or guarded/monitored functions. Both channels are monitored and cross checked for proper operational switch states.
These outputs must operate in tandem for a valid switch function to be recognized by the FYQLA1-140R-3. If the output channels of the switches are not functioning in a synchronized manner the amplifier will not accept the switch closure as a valid.
Door Interrupt System with FYQLA1-140R-3 Logic Amplifier Indicators The FYQLA1-140R-3 has indicators on front of the device for the following functions: • State of the connected input switches ▸ Two indicators per switch input (channel A & channel B) ▸ Indicator is illuminated (on) when the switch state is open •...
Door Interrupt System with FYQLA1-140R-3 Logic Amplifier Guided relays The door interrupt system incorporates two force-guided safety relays that are monitored for proper operation and generate a redundant output for application use. Input devices Magnetic switches The 50FY41 series hall effect door switches are a noncontact, magnetic actuation system consisting of a sensor and a magnetically keyed actuator.
Panel mounted inside an enclosure using the four mounting feet in the stainless steel housing. The FYQLA1-140R-3 is intended to be installed in a clean and dry environment. A control cabinet must be used to guarantee that the unit is exposed to no worse than an IP20 environment.
Door Interrupt System with FYQLA1-140R-3 Logic Amplifier Electrical installation Switch the main machine power OFF prior to installation! The machine could inadvertently start during installation. The door interrupt system fulfills the EMC requirements in accordance with EN/IEC 61326-3-2:2008 for safety related systems.

Door Interrupt System with FYQLA1-140R-3 Logic Amplifier Commissioning and startup Do not commission without a check by qualified safety personnel! The door interrupt system must be installed by qualified personnel who are properly trained in the installation, application, and usage of the FYQLA1-140R-3 product.
Door Interrupt System with FYQLA1-140R-3 Logic Amplifier Diagnostics Faults The door interrupt system has multiple LEDs mounted on the top of the device to provide diagnostic and troubleshooting assistance. LEDs are provided for each switch input pair, indicating the status of the individual channel. Also provided are output LEDs indicating the status of each of the safety relays.
Door Interrupt System with FYQLA1-140R-3 Logic Amplifier Fault diagnosis If fault LED flashes and no sensor alignment problem can be found: • Turn off power • Unwire sensors from input terminals • Power up unit • If fault LED begins to flash repeatedly after 2-3 seconds, the system needs to be replaced.
