Power Supply Replacement—All Microprocessor Controlled
Machines Except the CBW
®
This instruction applies to two power supply replacement kits which cover all Milnor
microprocessor-controlled machines except the CBW
®
. The kits are as follows:
• 08PSS3401N—This is for
older
machines and
contains bracketry and wire harnesses
which are only needed if the bracketry and harnesses supplied with the original equipment are
different from those in the kit.
• 08PSS3401X—This is for
newer
machines and
does not contain bracketry or wire
harnesses. The new power supply physically matches the old
.
A metal oxide varistor (MOV) and a regulating resistor are supplied with both kits. The MOV
must be installed across the new power supply's incoming power conductors, on any machine.
The resistor is used
only
on certain machines. It must be installed across the new power supply's
5 volt DC output conductors, as shown in Figure 2, on any applicable machine.
Please verify that all components listed in the kit parts list were supplied. Contact the Milnor
Parts Department if any items are missing.
WARNING 1 : Electrocution and Electric Shock Hazards
—You can be electrocuted or
seriously injured if you come in contact with 240 VAC or 120 VAC (depending on model)
power, which is present in the processor electric box.
• Lock off and tag out power to the machine while replacing the power supply.
• Use caution while testing and adjusting the new power supply with power on.
• Do not attempt these procedures unless qualified and authorized.
CAUTION 2 : Component Damage Hazard
—Electronic components will fail if not
properly connected. Warranties can be voided if failure to follow these procedures results in
damaged components.
• The ground trace on the power supply must be connected to the chassis of the machine, as
explained herein.
• The regulating resistor must be
installed
if the machine is a coin, single formula, System
7
®
or E-P Plus
®
washer-extractor type and
omitted
if any other machine type, as
explained herein.
• Carefully read and understand this instruction before proceeding.

Mounting the New Power Supply
Depending on the original equipment, new bracketry may be needed to accommodate the new
power supply. Whether or not this is the case, the new power supply board must be mounted as
shown in Figure 1.
