3.2.5 Replacing the AC/DC Converter (Pulsed Power Packs A5 to A8)
Replacing the AC/DC Converter (Pulsed Power Packs A5 to A8)
Parts, equipment and tools
▪ AC/DC converter (pulsed power pack – A5, A6, A7) [03055232-xx]
▪ AC/DC converter (pulsed power pack – A8) [03076588-xx]
Overview
SX4 X34iS – Ov erview of Pul sed Power Pac ks
The pulsed power packs are located in the rack unit be-
tween location 3 and 4.
A5) Pulsed power pack (24 VDC, set to 25 VDC)
for Power Fail, safety circuit SSK, tape cutter, PCB Han-
dling
The power fail signal is generated by the pulsed power
pack A5 and sent to the GCU and HCU. (X200:9,
X200:10)
A6) Pulsed power pack (27 VDC)
for FCU (gantry 1 and 4)
A7) Pulsed power pack (27 VDC)
for FCU (gantry 2 and 3)
A8) Pulsed power pack (36 VDC, to be set to 42 VDC)
For HCU (gantry 1 to 4)
NOTICE!
NOTICE! Check the set values and correct if
necessary.
