Page 4: Introduction
Due to the fact that they describe the operation of a safety device, these operating instructions are of a binding nature. The wenglor safety device with the designation “Light Array” is described in these operating instructions. 1.2 Function and Use for Intended Purpose The light curtain monitors the safety field between the transmitter and the receiver. -
Page 5: Explanation Of Symbols
Start-Up Inhibit This function is activated along with the „Restart Inhibit Function“. When power supply is switched on (e.g. after a power failure), the safety outputs (OSSD) remain in the off state. Acknowledgement is accomplished by activating an acknowledgment key. 1.4 Explanation of symbols NOTE! A note draws attention to useful tips and suggestions, as well as information... -
Page 6: Description Of The Safety Device
2. Description of the Safety Device 2.1 General The light curtain monitors the safety field between the transmitter and the receiver. If the safety field is penetrated by an obstruction, a switching command is triggered. This switching command may prevent initialization of a hazardous machine motion, or may stop an action which has already been started. -

Page 10: Securing The Danger Zone
All specified data make reference to the following revision level: 22.05.2019 Technical changes to the product described herein, printing errors and/or any possible incompleteness of this product description may not be construed as cause for asserting any legal claims whatsoever against wenglor sensoric GmbH. - Page 11 Over-Travel Time T Due to the fact that interrupting the safety field during hazardous motion does not result in immediate stopping of the machine, over-travel time T must be taken into consideration. The distance between the safety field and the point of danger must thus be large enough to assure that the point of danger cannot be reached until hazardous motion has come to a standstill.

NOTE! The safety field’s pilot beam may not be continuously interrupted. DANGER! The adjustment procedure must be repeated each time the device is remounted (e.g. change in operating range). 5.2 Function Modes 5.2.1 Safety Operating Mode This function type is preselected at the factory. When the Safety Light Array is set up in accordance with section 5.1.3, the device is in the safety operating mode. -

5.3 Functions All of the blanking options described below influence reliable recognition of objects by the Light Array. Before us- ing a blanking option, always check to make sure it is permissible. 5.3.1 Fix Blanking Various applications which make use of Safety Light Array necessitate that certain objects protrude into the safety field during the entire duration of operation. - Page 27 Permissible: If beams have been blanked, other precautions must be implemented which preclude any access to the point of danger via the object’s shadow (mechanical curtain). Please observe the following: The “restart inhibit” and “contactor monitoring” functions can be activated as required in the fix blanking operating mode.
