of 32/32
LIGO-D1200757-V4 1 D1200757 Sequencer – Insertable Input is from 4 (four) DC Power Supplies: +24VDC, -24VDC, +18VDC, and -18VDC. This sequencer prohibits the 18V supplies from being present prior to the 24V supplies. When the ON/OFF Switch is in the ON position, +24 and - 24 are passed to the Output side, and the internal relay switches are closed so that +18 and -18 are passed to the Output side as well. The relays are operated independently. The +24VDC controls the +18VDC and the - 24VDC controls the -18VDC. Output is intended to go to two standard power strips: 0ne +- 24VDC strip and one +-18VDC strip.

LIGO-D1200757-V41D1200757 Sequencer Insertable

Input is from 4 (four) DC Power Supplies: +24VDC, -24VDC, +18VDC, and -18VDC. This sequencer prohibits the 18V supplies from being present prior to the 24V supplies. When the ON/OFF Switch is in the ON position, +24 and -24 are passed to the Output side, and the internal relay switches are closed so that +18 and -18 are passed to the Output side as well.The relays are operated independently. The +24VDC controls the +18VDC and the -24VDC controls the -18VDC. Output is intended to go to two standard power strips: 0ne +- 24VDC strip and one +-18VDC strip.
