Fan Control Boards Wiring Diagram
AS1668 fan controls are mounted in
MX1
15U panels by using
MX1
AS1668 3U 19” rack doors (FP1056) that come
with 2 fan controls fitted. Each door can accommodate 12 controls in total by the addition of five FP1057 Fan
Controls Expansion Kits. Each kit provides 2 fan controls. The
MX1
panel can support up to 126 fan controls (63
boards), although additional cabinets will be required for more than 36 controls in a 15U cabinet.
Installation of the
MX1
Fan Controls is detailed in the
MX1
Fan Controls Install Instructions (LT0587). A copy of
LT0587 is included with every FP1056

expansion kit.
A generalized wiring arrangement is shown in Figure 36.
Note:
The DIP switch on each fan control needs to be set to a unique odd number from 1 to 125. All controls must have
their ‘M’ switch set to ON except the one that connects to the
MX1
Controller or
MX
Loop Card serial port, which
has its
‘M’ switch set to OFF.
INITIAL POWER ON
The
MX1
is shipped with a factory default configuration loaded.
WARNING:
Do not connect the battery when first powering up. Use the mains power supply alone to start with,
so that the current into any wiring faults will be limited to a reasonably safe level.
