The MS4800 light curtain family is an all-purpose light curtain available in three distinct versions. These versions are identified as the MS4800A, MS4800B and the MS4800S. The MS4800A and MS4800B feature set (configuration) can be changed through the use of an external device called the Programming Diagnostic Module (PDM) and on the MS4800S through selector switches.

PDM Functions

The PDM is used to program, configure and troubleshoot MS4800A and MS4800B systems. A qualified person simply plugs the PDM cable into a mating connector on either the transmitter or receiver. The PDM draws power from the curtain and allows quick display of the light curtain’s status for troubleshooting purposes. After log-in, all configuration settings can be accessed and programmed. The PDM has five function buttons that allow navigation through the set-up menus.
