Each tGard stack has between one and ten slots for different elements which create an interlock that is configured for your specific application. Each slot can have a mix of different things, this page gives technical details about E-Stops and Operator Controls. 

If you are not familiar with tGard we recommend you first read about the range in general on the tGard product page or look at our how to buy tGard page to understand the process of configuring the perfect stack.

Emergency Stop Element

 

Emergency stop element, version available with either a monitoring contact or illumination.

 

 

  • 2 positively driven force break Normally Closed contacts (uses none of the I/O pins).
  • Monitored version also has 1 output signal and this uses 1 output pin.
  • Illuminated version also has 1 input signal and this uses 1 input pin (it is illuminated by the controlling PLC, not by the action of pressing the E-Stop).
  • It is not possible for an E-Stop to be both Monitored and Illuminated.
  • E-Stop is always mounted at the top of any control elements, and below solenoid / head / safety switches / locks.
  • TEM & TEI E-Stops can be positioned at the bottom of the stack if required.
  • TED/C/W/V contacts are wired in series with another element in the stack e.g. TSS, to reduce pin requirements.
  • TET/M/P/I/S contacts are wired separately to all other elements in the stack.

3 Position Selector Operator Controls

Each 3 position selector switch uses 2 output pins.

  • Clockwise operation sets the lower assigned output High.
  • Middle position – output pins Low.
  • Anti-clockwise sets higher assigned output High.
  • Non-latching – spring return to original position.
  • Illumination (when selected) uses 1 input pin.
  • Inputs to the tGard stack are always assigned before outputs.

T3H –

  • Inputs to the tGard stack are always assigned before outputs.
  • Clockwise output assigned first.
  • Clockwise – 40° momentary, normally open.
  • Anti-clockwise – 90° latching, normally closed, individually wired.
