CONNECTIONS, CONTROLS AND INDICATORS
A. The Master Power Switch Circuit Breaker (with indicator light): Switches power from the line cord to the rest of the unit and additionally provides overload
protection (rated at 15 Amps at 120 VAC). Also provides “power on” indication via the illuminated switch actuator. Master Switch is enhanced by a switch guard to
prevent accidental power switching.
B. The System Switch (single pole, double throw, center off, momentary): Initiates system start for system sequence up and down. When the master switch
(described above) is on, depressing the top of the system switch initiates the power up sequence. Outputs will activate in ascending order from one to six. The sequence
interval delay and start delay are determined by the “delay adjust” settings (described later). Depressing the bottom of the system switch initiates the power down
sequence. Outputs will deactivate in descending order from six to one. The “delay adjust” settings also function in the “sequence down” mode.
C. Remote Control Terminal Block: This terminal block (located on the rear of the unit) is wired parallel to the system switch. This provides remote control of the system
switch functions. This terminal block has three positions: system up, common, system down. A separately provided switch (single pole, double throw, center off) may be
connected to this terminal block and installed in a remote location (providing a secondary control location). If multiple sequencers are used, the remote control switch may
be connected to the terminal block on any sequencer in the system. This is not limited to one remote location. Several remote switches can be installed if multiple
control locations are required. It is recommended that a “momentary” switch be used, since a control switch left in either the up or down position would “lock out” all
other switches installed on the system, including the system switch on the unit. However, this may have an
advantage if the installation requires a “lock out” function at a specific location. A key type switch (USC-KL, USC-K)
can be installed for added security. Standard telephone cable may be used for the connection
of the remote control switch(s) (500’ max with 22-gauge wire). Longer distances can be achieved by increasing
the wire gauge. The voltage on the remote control circuits is 5 VDC (class 2 wiring).
Another function of the remote control terminal block is to provide a connection point to allow “daisy chaining” of up to three sequencers together. They function
as three separate controllers, controlled by a single actuation of any system switch, or they can be programmed to act as a single 18 channel controller (three units with
six channels each). This programming function is described later, see “delay adjust switches”.
D. Status Indicators: Six yellow LED indicators are provided to allow visual monitoring of the outputs. As each output is activated, the corresponding channel LED
illuminates (one to six), thus allowing the operator to monitor the status of the sequence operation. Conversely, the LEDs will turn off sequentially (six to one)
during the “sequence down” operation.
E. Delay Adjust Switches: There are two delay adjust switches on the unit: Interval Delay (between sequence steps) and Start Delay (both up and down system start).
1. (Interval) Delay Adjust Switch: Three position switch providing a one, three and six second delay between sequence steps. The switch actuator is a slide type, and is
located on the front of the unit. The delay is common to all channels (one through six).
2. Start Delay Switch: Mounted on the rear of the unit. This switch is a four position slide switch (switch positions 0-1-2-3) providing a delay on both “system up” and
“system down” operation. This allows the interconnection of up to three, six channel sequencers to operate as a single 18 channel unit; by delaying the start of
sequencer #2 until sequencer #1 has completed it’s sequence function, then subsequently initiating the start of sequencer #3. At the same time, individual units
are selectively programmed to initiate the “sequence down” function in reverse order. (i.e. unit #3 will begin sequence down first,then unit #2, then unit #1,
“first on – last off”). Switch position #0 is for single sequencer (no start delay, up or down).
The sequencing functions are controlled by elapsed time, not by a “trigger pulse”, therefore, sequence interval and start delay time settings provide great latitude when
interconnecting (“daisy chaining”) up to three units together. This “elapsed time” programming method eliminates many of the problems experienced when a “trigger”
pulse is sent from one sequencer to the next. The start delay is directly proportional to the interval delay, (the longer the interval delay, the longer the start delay).
When “daisy chaining” two or three sequencers together, it is important to set the interval delay the same on all units to provide proper synchronization.
HINT: To ensure a good, longer lasting
connection when connecting wires to a
screw-type terminal block, do not twist or
tin(solder) the conductors on stranded wires.

CONNECTIONS, CONTROLS AND INDICATORS (Continued)
F. Green LED “Ready” Indicator: This LED, located on the front panel, will be illuminated when the master power switch is turned on. When a start delay function is
selected via the “start delay switch”, this light will blink indicating that the unit has received a command to initiate a sequence up or down. The LED will blink for
the duration of the selected start delay time (from the time sequence is initiated to the time first channel output is energized). This LED also serves as a DC power
supply fuse indicator.
Each output has three connection options:
• 12 VDC output (individual channel terminal block).
• Contact closure (individual channel terminal block).
• 12 VDC output (all channels and (+) and (-) constant). Terminated in a RJ-45 jack.
Each channel has a plugable terminal block output, consisting of four terminal positions. Terminals (1) and (2) provide a dry switch closure and terminals (3) and (4)
provide 12 VDC output. These outputs activate simultaneously and can be used at the same time (i.e. one output can be used for control and `the other can be used
to monitor sequence status). These outputs are electrically isolated from each other via a double pole electro-mechanical relay. Maximum total load on the external
12 VDC section is 750mA. Maximum current capacity on each switch closure is 5 Amps.
I. RJ-45 Jack Output: This output is connected in parallel to the 12 VDC output on the individual channel terminal blocks. It provides a convenient connection point for
utilization devices or status monitor indicators. Positions 1 - 6 output +12 VDC corresponding to sequence channels 1 through 6, position 7 is –12 VDC (common),
and position 8 is a +12 VDC, parallel to the green “LED ready indicator” circuit, which is photo-optically isolated from the internal 12 VDC supply. This jack can be used
in addition to, or instead of the individual channel terminal blocks, however, care should be taken not to exceed the load restriction of 1.5 Amps total.
This jack may also be connected to USC-KL remote wallplate key switch or USC-SWL remote wallplate switch.
J. Supplemental grounding and bonding stud.
G. Power Supply Fuses: In addition to the master switch/circuit breaker, the DC power supplies are protected by two fuses. One located internally, which DC protects
internal components, and one located on the rear panel (1.5A MAX) which protects output circuitry. An overload on the external customer provided wiring will
have no effect on the internal voltage power supply or its associated fuse.
Fuse Warning: For continued protection against risk of fire, replace only with same type and rating of fuse.
Avertissement Fusible: Pour ne pas compromettre la protection contre les risques d'incendie, remplacer par un fusible de même type et de memes caractéristiques
nominales
H. Plugable Terminal Block Outputs: The control outputs, located on the rear of the unit, are provided via “plugable” terminal blocks, which allow for pre-wiring prior
to installation of the controller. This feature allows fast and simple controller installation and reduces risk of potential damage due to premature controller
installation. Additionally, if controller replacement is necessary, it can be replaced without rewiring of control circuits, just “plug and play”.
Warning: Do not connect 12V outputs to RLM Modules. Use Dry Contacts Only.

The remote terminal block on the rear of the USC-6R has two functions:
1. Enables the interconnection of up to three USC-6R’s to function as a single 18 step unit. Allows up to three USC-6R sequencer to operate under control of the
system switch on any sequencer in the group (dependent on delay start switch settings).
2. Allows the connection of a customer provided remote control switch.
Note: The above described functions (1 and 2), may be used simultaneously.
