BMRX SERIES ROTARY LEVEL INDICATOR
MOUNTING PLATES
Mounting plates are necessary when a completely assembled unit is to be mounted on the bin
wall from the outside. A 5-1/2” hole is cut in the bin. Six bolt holes are drilled around the hole to
match the mounting plate. The plate, with the unit attached, is then bolted in place. All mounting
plates are available in carbon and stainless steel.
For use with all rotary
level controls. This
model is used for
top of bin installa-
tions where shaft
extensions and shaft
guards are required.
For use with all
rotary level
controls. This
model is used
primarily for
side of bin
installations.
BMRX Wiring
2.2 Input Power and Field Wiring
The BMRX is available in AC and DC Models. The AC Models are available to be pow-
ered from 24 VAC, 115 VAC, or 230 VAC 50/60 Hz supply voltages. The DC Models are
available to be powered from 12 VDC or 24 VDC supply voltages. See the voltage rating on the
nameplate for the appropriate supply voltage. Field wiring should conform to all national and
local electrical codes and any other agency or authority having jurisdiction over the installation.
For power input, use wire that is sized and rated for the maximum voltage and current as per
equipment ratings and has a temperature rating of at least 70
°
C. For relay outputs, use wire
that is sized and rated for the maximum voltage and current as per application, up to 250
VAC 10A, and has a temperature rating of at least 70
°
C. Installation shall be done by
qualied personnel.

Input Power
Power input to the BMRX is connected to the
LINE terminals labelled L and N.
AC Models
On AC models if one of the conductors
is grounded, it should be connected to
the N terminals. The ungrounded conductor
should be connected to the L terminal.
If neither conductor is grounded then one
of them is connected to the N terminal
and the other to the L terminal.
DC Models
On DC models the negative
conductor should be connected to the
N terminal and the positive conductor
should be connected to the L terminal.
