Alternate Function for K5

An alternate K5 function may be selected by installing a jumper onto JP2 on the control card. The STANDBY-READY function is asserted (K5 closed) when the power supply completes the transition from the STANDBY-WAIT (flashing yellow) to the STANDBY-READY state (steady yellow). K5 remains closed for the LAMP ON state (flashing or steady green), the QRO state (alternate flashing of yellow and green), and the return to the STANDBY-READY state (steady yellow). K5 opens during the OFF/RESET state and the STANDBY-WAIT state (flashing yellow) from either the LAMP ON state or from the OFF/RESET state.
