Momentary switches,
for
example non-latching
push buttons, are momentary contact devices that
maintain their contact position (open or closed) only
as long
as the switch is
held
in
a given position.
When the switch actuator is
released,
the switch
reverts to its
normal position (such as the Fuman
RS-2).
A switch
of
either kind may be used to actuate the
M-8S's
remote operation. Maintained switches are
generally
most convenient when there is
only
one
remote switch
location
used to
control
the
M-8S.
When more than one switching
location
is required,
momentary switches
allow
the M-8S
to be se-
quenced
ON
or OFF from multiple locations.
Power Indicator:
The
POWER
indicator is
illuminated
any time power
is
applied to the M-8S. This LED indicates the un-
switched
outlets are powered.
CONNECTING MULTIPLE
M-8S UNITS
TOGETHER
Multiple M-8S
units can be
linked
together (via their
remote interface) to
control additional
system needs
or requirements. There are two basic connection
methods for the
M-8S; Serial and
Parallel.
The
connection method you use may be series, parallel,
or a combination thereof and
will
depend upon the
requirements
of
your specific
installation.
M-88 in Series Mode:
Series mode connection is
normally used when
more than three
delay
stages are needed. Com-
bining
M-8S
units
in
series requires an accessory
relay
(Furman P/N PS-REL) to trigger secondary
(downstream) units. When connecting
M-8S
units
in
series, the
PS-REL is
plugged
into one
of
the
DELAY 3 outlets
on
the primary (upstream) unit and
the relay terminals on the
PS-REL
are connected to
the remote interface
on
the secondary (downstream)
unit. When the DELAY 3
outlets
on
the primary unit
are activated the
PS-REL is
also
activated
-which
triggers the sequence to start
on
the secondary
(downstream)
M-8S. Series
mode connection can
be repeated for any number of M-8S
units. Further
information on the
PS-REL
can be found
on
the
Furman website: http://www.furmansound.com/pdf/
manuals/PS-REL_manual.pdf
M-88 in Parallel
Mode:
Parallel
mode can be used to activate loads
in
excess
of
15 Amps by distributing the
loads
over
one or more M-8S
units. When connected
in
paral-
lel
(see Figures A
and
8,
pg. 8)
all connected
M-8S
units
will
activate their
Delay
1 simultaneously.
The
activation times
of
Delay
stages 2 and 3
will
depend
upon
the delay
setting
of
each unit.
If M-8S
units
are operating
in
parallel
to increase load
capacity,
each unit
should
be connected to
an
independent
15 to
20
Amp branch circuit and breaker. If
in
doubt,
please consult
with a
qualified electrician
to verify
that your facility
can support the
load
currents
required for your
installation.
