DIP Switch position #3 (Factory default is OFF)
DIP Switch position 3 defines the switching preference
for switches or devices connected to the REM pin on the
Remote Interface. If this switch is in the ON position,
the PS-8RE III will operate in Momentary mode. If this
switch is in the OFF position the product will operate in
Maintained mode.
Maintained switches, for example toggle switches or
latching push-ON / push-OFF push button switches
maintain their contact position until the switch is actuated
a second time. Thus a switch that is closed will remain
closed until the switch position is changed.
Connecting Multiple PS-8RE III Units Together
Multiple PS-8RE III units can be linked together (via their
remote interface) to control large AV systems. There are
two basic connection methods for the PS-8RE III; 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.
PS-8RE III in Series Mode
Series mode connection is normally used when more than
three delay stages are needed. Combining PS-8RE III
units in series requires an external 240 VAC coil SPST
relay to trigger secondary (downstream) units. When
connecting PS-8RE III units in series, the coil of the relay
is plugged into one of the DELAY 3 outlets on the primary
(upstream) unit.
Momentary switches, for example non-latching push
button switches, (including the Furman RS-2) 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 actuator is released,
the switch reverts to its normal position.
A switch of either kind may be used to actuate the PS-8RE
III's remote operation. Maintained switches are generally
most convenient when there is only one remote switch
location used to control the PS-8RE III. When more than
one switching location is required, momentary switches,
operating in parallel allow the PS-8RE III to be sequenced
ON or OFF from multiple locations
PS-8RE III in Parallel Mode
Parallel mode can be used to activate loads in excess of 10
Amps by distributing the loads over one or more PS-8RE
III units. When connected in parallel (see figures B and C)
all connected PS-8RE III 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
PS-8RE III units are operating in parallel to increase load
capacity, each unit should be connected to an independent
AC circuit rated at 10 amps or more. If in doubt, please
consult with a qualified electrician to verify that your facility
can support the load currents required for your installation.
