Battery

Switch
• Diesel Oxidation Catalyst (DOC) and Selective
Catalytic Reduction (SCR)
• Diesel Oxidation Catalyst (DOC) Diesel
Particulate Filter (DPF) and Selective Catalytic
Reduction (SCR)
• Diesel Exhaust Fluid (DEF)
The battery disconnect switch is designed to isolate
the engine and application from battery power.
In some applications an auxiliary electrical circuit
may have been included that will allow the DEF
system to cool down and purge even if the battery
disconnect switch is in the off position. Once the DEF
system cools down and the purge procedures are
complete, this auxiliary circuit (if installed) will open.
This circuit then isolates the battery from the rest of
the electrical system.
NOTICE
Perkins strongly recommend the installation of the
wait to disconnect lamp on all applications.
The wait to disconnect lamp will be illuminated during
engine operation, and only when extinguished should
the battery disconnect switch be turned off.
For a DOC and SCR aftertreatment system, allow 10
minutes after the engine has stopped before you turn
the battery disconnect switch off.
For a DOC, DPF and SCR aftertreatment system
allow 15 minutes after the engine has stopped before
you turn the battery off.
If digital communication is lost, the wait to disconnect
lamp will operate for minutes 15 minutes on both
aftertreatment systems after the engine has stopped.
Disconnecting the battery power too soon may
prevent cooling of the DEF system and purging of the
(DEF) lines after the engine is shut down.
Not allowing the DEF system to be cooled can
damage the system. Not allowing the DEF purge to
be performed can damage the DEF system.
For more information on DEF cooling and purging
times, refer to this Operation and Maintenance
Manual, “Product Description” and see title

and Purging of the DEF Lines

Gauges
and
Indicators
Your
engine
may
not
have
the
same
gauges
or
all
of
the
gauges
that
are
described.
For
more
information
about
the
gauge
package,
see
the
OEM
information.
Gauges
provide
indications
of
engine
performance.
Ensure
that
the
gauges
are
in
good
working
order.
Determine
the
normal
operating
range
by
observing
the
gauges
over
a
period
of
time.
Noticeable
changes
in
gauge
readings
indicate
potential
gauge
or
engine
problems.
Problems
may
also
be
indicated
by
gauge
readings
that
change
even
if
the
readings
are
within
specifications.
Determine
and
correct
the
cause
of
any
significant
change
in
the
readings.
Consult
your
Perkins
distributor
for
assistance.
Some
engine
applications
are
equipped
with
Indicator
Lamps.
Indicator
lamps
can
be
used
as
a
diagnostic
aid.
There
are
two
lamps.
One
lamp
has
an
orange
lens
and
the
other
lamp
has
a
red
lens.
These
indicator
lamps
can
be
used
in
two
ways:
• The indicator lamps can be used to identify the
current operational status of the engine. The
indicator lamps can also indicate that the engine
has a fault. This system is automatically operated
via the ignition switch.
