LEGRAND Wattstopper Manual De Uso página 2

Both Room Controllers communicate to all other DLM devices connected to the DLM Local Network. Connections shown are for
example only. The low voltage LMRJ cables can connect to any DLM device with an open RJ45 receptacle.
All line voltage wiring is #12 AWG. For the LMRC-212, each relay is rated for up to 20A; total load not to exceed 20A. For the
LMRC-212-347 each relay is rated for up to 15A; total load not to exceed 15A. Specified load types can connect to any load relay.
Do not connect different load types to the same relay. For dimming ballasts or drivers, connect the 0-10V control wires to the 0-10V
terminals that match the load relay output connection.

When Normal Power is available:
In this scenario, the LMRC-212's 0-10VDC dimming circuit is connected to and alters the light level of both normally powered lighting
loads and emergency powered lighting loads. This 0-10V signal is generated individually by each ballast or driver when they are
powered. Wattstopper recommends using a ELCU device so that when Normal Power is available and the normal load has been
turned off by any DLM device (OS, photocell, or dimmer switch, or LMRC override button), the ELCU will turn off the Emergency Load
as well. (Note that without an ELCU type device, the normal power load can be turned off by the room controller, but the emergency
power device (fixture) can only be dimmed to lowest level. It will never turned completely off.)
When Normal Power is unavailable:
The circuitry in the LMRC-212 will
ensure that when normal power
to the room controller fails for any
reason, the 0-10VDC dimming
circuit in the LMRC-212 will no
longer be controlled and instead
will revert to an open circuit.
Since no device controlling the
0-10V circuit, any fixture that is
fed by emergency power will go
full on. Fixtures fed by normal
power will of course be off since
there is no power available for
their operation.
NOTE: If additional normal and
emergency lighting loads
are controlled by the
LMRC-212, a separate
ELCU device is needed.
