Precautions for Installation

1 Locate the SL-M Series so that the angle of reflection θ

2 Determine the distances shown in the diagram to the right so that the

following three conditions are met: the distance A separating the Transmitter and the first SL-M Series unit is greater than or equal to

0.3 m (11.81”); the distance B separating the two SL-M Series units is greater than or equal to 0.3 m (11.81”); and the distance C separating the Receiver and the second SL-M unit is greater than or equal to

0.3 m (11.81”). Do not allow the total distance between the GL/SL Transmitter and Receiver (i.e. the distance A+B+C in the diagram) to exceed the operating distance given in the “Specifications” for the number of SL-M Series units being used.

When using the SL-M Series to create a detection zone where the approach of human body or objects to a hazard can be detected, a misalignment in the mounting angle of either the GL/SL Series or SL-M Series may cause the beam from the GL/SL Series Transmitter to enter the GL/SL Series Receiver without being reflected by the mirror surfaces of all or some of the installed SL-M Series. This is extremely dangerous, as the system can not offer complete protection against the expected hazard and may not be able to detect people or objects as they approach the hazard at the position where they must be detected. To avoid this danger, install the SL-M Series in accordance with the following warnings. Failure to follow these warnings may result in significant harm to machine operators, including serious injury or death.

• SL-M Series installation requirements based on the position of the GL/SL Series Transmitter or Receiver

Note that these requirements do not apply to just either the GL/SL Series Transmitter or Receiver but rather apply to both units.

When installing a GL/SL Series Transmitter at Position A on Graph 1

When a GL/SL Series Transmitter and one SL-M Series unit have been installed as indicated in Definition 1 in the following diagram, no other SL-M Series units or GL/SL Series Receiver can be installed in Area B in Graph 1. In other words, only one SL-M Series unit can be installed in Area B. (When installing two or more SL-M Series units, see “SL-M Series, GL/SL Series Transmitter or Receiver installation requirements based on the position of the SL-M Series” for more information.)

When installing a GL/SL Series Receiver at Position A on Graph 1

When an GL/SL Series Receiver and one SL-M Series unit have been installed as indicated in Definition 1 in the following diagram, no other SL-M Series units or GL/SL Series Transmitter can be installed in Area B in Graph 1. In other words, only one SL-M Series unit can be installed in Area B. (When installing two or more SL-M Series units, see “SL-M Series, GL/SL Series Transmitter or Receiver installation requirements based on the position of the SL-M Series” for more information.)
