OPERATING
INSTRUCTIONS
INTRODUCTION
Description
The
TEKTRONIX TM-504 Power Module is
a main-
frame
for
the
TM 500
Series of Modular
Instrumentation.
It
accepts
up
to four independently
functional plug-in
modules
to
form
a compact
versatile
and low cost instru-
mentation
system. The TM 504
is
a
basic
power source
and
provides an interconnecting scheme
for the other
members
of the
TM 500
Series family.
Factory options
allow
customer
modification using
signal access
at
the plug-in
module/power
module interface
to
provide rear
panel
inputs
and outputs,
and interconnections
between
compart-
ments.
Power Source
This
instrument is
designed to operate from a
power
source
with its
neutral
at or
near earth
(ground) potential
with
a
separate
safety-earth conductor.
It
is
not intended
for operation from
two phases of
a
multi-phase system,
or
across the
legs
of
a
single phase, three-wire
system.
Power
Usage
With four plug-in
modules installed,
the
TM 504 can
require
up to 220
W
of
power at
the
upper limits
of the
high line
voltage ranges.
Actual
power
consumption
de-
pends on
the
particular
module
combination
and operating
mode selected
at any one time.
NOTE
The compartment
closest to
the
PULL
ON POWER
switch is high
power.
Some of
the
TM
500
Series
plug-in
modules require high
power
to
operate
at
their
maximum capabilities.
Operating Temperatures
The TM 504 can
be
operated
in
an ambient air
temperature of
0°C to
50°C.
Thermal
cutout devices
protect
the
system by disconnecting the
power to
the
TM
504 Power Module when
internal
temperatures rise
above
a
safe operating
level.
These devices
automatically
return
power
to
the unit when the
internal temperatures
return
to
a
safe
level.
Since the
TM 504 can be stored
in
temperatures between
—
40°C
and
+75°C,
allow the
instruments's chassis
to
return
to within the
operating limits before applying
power.
POWERING
UP
Plug-In
Modules
It is not
necessary
that all
the plug-in
compartments be
utilized in
order
to
operate the
Power Module. The
only
modules
needed are those necessary
to
accomplish
the
task.
Turn
the Power Module off before inserting
the plug-
in; otherwise,
damage may occur
to
the
plug-in
circuitry.
Module Installation
1
.
Check the location
of the white
plastic barriers
on the
TM 504 interconnecting
jack
to
ensure
that their
locations
match the
slots in the
edge
of
the
plug-in
module's circuit
board.
2. Align the
plug-module
chassis with the
upper and
lower guides
of the selected
compartment.
Push the module
in
and
press
firmly
to
seat the
circuit
board
in the
interconnecting jack.
(Remove the
plug-in module
by
pulling
on
the white release
latch located
in the lower
left
corner of each
module.)
