ESA series is mainly used for safety protection for stamping machinery, which adopt controller to monitor and output signal of light curtains.
ESA series supports AV110-220V, AC380V voltage and output relay signal. ESA series is designed according to EU safety standard, whose main components are imported.
Good self-diagnosis, easy to operation, and strong anti-vibration ability make ESA series can work in different hazardous equipment, and well protect operators from accident.

Features :
 

• AC110V-220V, AC380V wide voltage for stamping machinery;
• Controller reliably monitor signal of light curtain by pulse detection method, which effectively ensure that mistake signal will not be triggered when short circuit;
• Good performance to against electromagnetic interference of different machine motor;
• Anti-shock circuit and strong aluminum alloy enclosure well against vibration;
• Wire-syn good to against light interference;
• Controller output signal by relay isolation output mode, and the external control signal is completely isolated form internal circuit of barriers;
• Plug connecting between curtain & controller make wire connection easily and quickly,
• Multiple brackets for various environment mounting;
• One controller can work with more sets of safety light curtain for multi-faced protection;
• Long sensing distance up to 20m.

Wire Diagram :

• External Controller (P-Type)
  • L (brown) and N (blue) is input wire of AC110V/220V, please check and ensure right connection;
  • T (brown) and K (blue) should be connected with control circuit of machine shown as below. When beams are through, T&K are connected and the machine works well; When beams are blocked, T&K are disconnected to stop the machine.
    
    
• Internal Controller (Q)
  • Connection of T.K wire, under normal circumstance, Return No Protection no need);
  • Connection of T.K (need Return No Protection), Return No Protection function is usually achieved by machine, no need to connect additionally.
  • When it needs to be achieved by safety light curtain, you can connect wire as below method.
  • A pair of normally open contacts of the cam are connected in parallel with Tand K.

Controller Options : 




*Remark :

• Please check if light curtain control machine well before working and refer to step 4 to debug.
• Avoid movement of safety light curtain casually;
• The key of controller should be kept by professional engineers;
• Engineers need to adjust the sensing distance and position of light curtain after changing machine model;
• Power Supply should be cut off by professional operators when dissemble and maintain light curtain;
• 100 million times, reaching the service life, or after three years of use, it should be replaced:
• During use, be careful not to let workpieces, tools, wastes and other items collide with the photoelectric protection device.
• Push reset button to re-start machine, if curtains connected with reset button, and machine stop after beam blocked.
