6.6 Plug-In Modules– Status LED
In the case of the modules designed as plug-in modules, status LEDs are located in the upper left
corner. The position and function of these LEDs are described in the following.
MCP, MDC, MBC, MDA, MGO, MAO Modules
Fig. 50 MCP, MDC, MBC, MDA, MGO, MAO Modules, Status LEDs
Fig. 51 MCP, MDC, MBC, MDA, MGO, MAO Modules, Function Status LEDs
In the normal case, only one of the first three LEDs is on. If no LED is on, there is a problem with
the voltage supply to the module.
If the failure LED [LED No. 4] is on, you should contact an MSA service technician. If this cannot
be done right away, the module can be replaced if a spare unit is available [
