2.6 Wiring Schematics This section provides wiring schematics for L-827/L-829 Advanced Control Equipment
(ACE2).
See Figure 30 for the L-827/L-829 ACE2 wiring connections to the constant current regulator
(CCR).
2.6.1 Connectors Figure 24: Internal Connections
NOTE: A. Terminal block J4 accepts any discrete contact closure that uses 24 to 250V AC/DC control voltage.
Examples of useful inputs are: CCR Over Current, CCR Over Voltage, CCR Primary Power, CCR Remote Local,
CCR Open Circuit, CCR Access Door open, etc.
NOTE: B. Terminal block J5 carries system latching relay outputs that are used to control brightness steps of a
CCR. These outputs can also be configured to control any element that requires an ON/OFF contact closure. The
output current is 1A max so 20 AWG wire or larger is suggested. In addition, these terminal blocks can be
configured to control both CCR brightness steps and a L-847 Circuit Selector Switch.
