Relay/Transformer (R/T Box)

Standard Transition

Each MX250 microprocessor based ATS controller requires a relay/transformer box to apply line voltage to the ATS operator via coil control relays. Also required is power for the MX150 printed circuit board and an appli- cation of sensing voltage proportional to line voltage. This is accomplished by the relay transformer box. This method of switching operator voltage and applying power and sensing voltage to the printed circuit board isolates

the controller from harmful line transients. Two versions of the R/T box exist depending on the type of ATS (standard transition or delayed transition).

The following layout drawings of the R/T Box compo- nents (standard and delayed transition) include a bill of materials for replacement parts. Schematics are included to indicate proper wiring.
