Wiring: The double blank sensor provides two discrete outputs which are activated based on the material thickness detected each time the gripper closes. Table 1 outlines the various states of the Sensor LED(s), 1 Sheet output and 2 Sheet output. These two outputs can be used independently or together. PLC logic can be written to enable the part transfer, stop the part transfer, initiate a double sheet shed routine and provide operator fault warnings depending on the requirements of your application. During calibration the sensor establishes two thresholds which are used to drive the 1 sheet and 2 sheet outputs. 1 SHEET OUTPUT – This output will turn on whenever the detected thickness falls between the lower and upper thresholds (a single sheet is present). It will be off while the detected thickness falls below the lower threshold or when the gripper is open. This output can be used by itself with logic written that allows the transfer to proceed if the 1 sheet output turns on, but not proceed if it is off. This approach does not differentiate between a no sheet condition or a multiple sheet condition. The 2 sheet output is required to make this distinction. 2 SHEET OUTPUT – This output turns off whenever the gripper detects a material thickness that is greater than the upper threshold as defined above or when the gripper is open. It will be on when below this threshold. The 2 sheet output can be used to stop part transfer and initiate a blank shed or multiple sheet rejection routine. Both outputs can be used together to indicate the following conditions: If 1 sheet is on and 2 sheet is on – Allow part transfer to proceed. If 1 sheet is off and 2 sheet is on – material is too thin or no part is present. If 1 sheet is ofaf and 2 sheet is off – initiate blank shed or blank rejection routine.
