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 12 VDC corresponding to sequence cha
nnels 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 is
olated 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.

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.
