The location of the 5501-381 board will be in the MicroNet TMR main control power supply chassis

which can hold up to two TMR supply boards but when being used together they must be in two

separate chassis but connected through ribbon cabling. One primary feature of this board is that it can

be replaced hot, being replaced hot means that the control chassis does not have to cease operation when the 5501-381 board is being removed.

On the front faceplate of the 5501-381 board, there are four LEDs, these four LEDs are as follows input

fault, power supply fault, overtemperature, and OK LED. The only green indicator on the board is the

OK LED which is turned on to indicate that the power supply is running as needed and no errors or faults have occurred. 

For all information regarding the 5501-381 board please refer to the 26166V2 manual which describes

this board or the 26167V1 manual which gives more in-depth information on the function of this board.
