PARAMETER CHANGE ENABLE Keyswitch

> Each RPS Channel (A, B, C, D & E) and ESFAS Channel (A, B & C) and ESFAS Voter Train (EVEN and ODD) include a PARAMETER CHANGE ENABLE Keyswitch.

> The PARAMETER CHANGE ENABLE Keyswitches are administrativelycontrolled and shall allow only one Channel to be placed into the PARAMETER CHANGE ENABLE position at a time.

> The Keyswitch contact is powered by 24VDC and is connected to an input channel on a S430 Digital Input Module for the TXS computer.
