GridScan/Pro SI modes • Delivery mode - blanking The GridScan/Pro SI is a very reliable SIL 2 certified safety The delivery mode features door blanking and resolution, light curtain. It was developed and designed to safeguard according to EN 12978:2009. This means there are... -
Page 5: Overview
As soon as the detection area is clear again, the output switches to indicate that the area is "clear". The blanking system (blanking mode, Chapter 4.2) is designed to mount directly into the guide rails. As the door closes, the GridScan/Pro SI recognizes the door as such and does not switch the output. Figure 3:... -
Page 6: Alignment
Avoid interference from blinking lights or infrared light sources such as photo cells or other light curtains. Do not install the GridScan/Pro SI in places where the emitter and receiver edges are directly exposed to light sources such as FL tubes or energy saving lamps. -
Page 7: Door Blanking
English Door blanking The GridScan/Pro SI can differentiate between a light beam interruption caused by an object and a light beam interruption caused by the closing door. The GridScan/Pro SI does this by analyzing the different interruption patterns. Closing door interruption pattern: The light beam interruption of a closing door starts at the topmost beam going downwards. - Page 8 Important for the static mode: When the GridScan/Pro SI is statically mounted (Figure 8) the door must not interrupt the beams (no door blanking).

Page 9: Electrical Connection
Electrical connection The GridScan/Pro SI has only a serial interface for the communication. No physical Push-Pull or OSE output is available. The functionality of test input or output is implemented in the communication protocol. For a safe installation, the light curtain needs to be installed, activated and tested according to the door control unit guideline. -

Page 15: Guidelines For Implementation (Rs485)
10.1 Functions of GridScan/Pro SI The GridScan/Pro SI with RS485 interface transmits single element information of the light curtain, and in the blanking mode the door position to the control unit. The data can be collected in different communication modes. -

10.2 Safety function RS485 CEDES communication protocol Data transmitted on the RS485 channel uses a safe, proprietary protocol which meets the requirements of SIL 2 as long as the following checks are performed by the door control unit. -

Internal fault is active if bit 9 internal failure in the state of light curtain byte is set. 10.3 Implementation of RS485 CEDES communication protocol (RC) For the implementation, the command Info: Communication test (0x23) can be used. The package of this command is processed even if the information is not correct and helps to implement the protocol to the door control unit. -
Page 18: Change Of Operation Mode (Blanking Into Static Mode)
5. Set the new operating mode by command Config: Set static (0x51) for static mounting or Config: Set blanking (0x52) for blanking mounting. If the change of the operating mode is successful, the GridScan/Pro SI restarts automatically. The mode has changed. The static mode is visible after the power-up with a blinking sequence of green and off. -
