SAFETY SUMMARY
Review the following safety precautions to avoid injury, prevent damage to the equipment and maintain protection
methods for hazardous locations.
The product should be installed, commissioned, and maintained by qualified and authorized personnel only. Install
according to installation instructions and comply with all national and local electrical codes.
If this product is used in a manner not specified by the manufacturer, the safety and hazardous location protection
could be compromised.
Use electrical wire that is sized and rated for the maximum voltage and current of the application.
An external overcurrent protection device or switch must be included in the installation and rated for the voltage
and current of the device and load. It should be installed near the equipment and identified as for that equipment.
Do not install this product in a manner which makes is difficult to operate the disconnecting device.
Properly ground the enclosure to an adequate earth ground. Observe all switch contact ratings as called out on
the nameplate and in the operating instructions. Insure that the enclosure cover is in place and secured tightly
after installation.
Before servicing, disconnect power from all circuits entering enclosure before removing cover. After any inspection
or servicing, insure the enclosure cover is in plate and tightly secured.
In potentially wet environments thoroughly seal all conduit entries.
Safety Terms and Symbols
WARNING: Warning statements identify conditions or practices that could result in injury or loss of life and the
operating instructions must be consulted. Risk of electrical shock.
CAUTION: Caution statements identify conditions or practices that could result in damage to this product or other
property.
Safety Precaution
CAUTION: Before removing the enclosure cover, open all circuits entering the enclosure. Be aware that there
may be more than one live circuit.

1.0 INTRODUCTION
The Bin-Master BMRX is a rotating paddle style level sensor which provides reliable point level detection for bulk
solids, including powder, pellet, and granular materials. The unit has a switch selectable fail-safe relay that will fall
to a "safe" condition in the event of a power failure.
The BMRX motor rotates the drive shaft and paddle at 1 RPM. When the vessel material fills to the level of the
indicator paddle, the material causes the paddle to stop rotating indicating a covered condition. When the material
falls away, the paddle starts rotating again to indicate an uncovered condition.
2.0 INSTALLATION
2.1 Location and Mounting
TOP MOUNT (For mounting plate options see figure 4 on page 6) Figure1
SIDE MOUNT (For mounting plate options see figure 5 on page 6) Figure 2
1. Locate and cut hole in top of bin to fit outside diameter of 1 1/4”
pipe coupling (1.950”).
2. Position coupling halfway into bin and weld.
3. Turn unit so conduit opening is in desired location.
4. Add 1/4” extension pipe to desired length with standard 1/4” cou-
pling on bottom end.
5. Cut 1 1 /4” support pipe approximately 4” shorter than overall
length of 1/4” pipe shaft when used with flexible coupling.
6. Insert 1 1/4” pipe into coupling and tighten.
7. Insert paddle into 1/4” coupling and drill holes for lock pins.
1. Locate and cut hole in side of bin to fit outside diameter of 1 1/4”
pipe coupling.
2. Weld on half of standard 1 1/4” pipe coupling to bin wall flush with
inside of bin.
3. Insert hub into coupling and turn to desired conduit position.
4. Screw paddle into place and replace lock pin.
5. Shaft and paddle should be shielded in low level mounting when
subjected to material flow.
6. For side mount, a solid coupler is recommended.

MOUNTING PLATES
2.2 Input Power and Field Wiring
The BMRX is available in AC and a DC Model. The AC Models are available to be powered from 24VAC, 115 VAC,
or 230 VAC 50/60 Hz supply voltages. The DC Models are to be powered from 12 VDC to 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 90°C and suitable for 25°C above the surrounding ambient temperature. For
relay output, use wire that is sized and rated for the maximum voltage and current as per application, up to 250VAC
10A, and has a temperature rating of at least 90°C and suitable for 25°C above the surrounding ambient
temperature. Installation shall be done by qualified personnel.
BMRX Wiring Figure 6
Mounting plates are necessary when a completely assembled unit is to be mounted on the bin wall from the out-
side. 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.
Full Coupling
For use with all Rotary level
controls. This model is used
for top of bin installations
where shaft extensions and
shaft guards are required.
Half Coupling
For use with all Rotary level
controls. This model is
used primarily for side of bin
installations.

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
connect 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.

2.3 Grounding
An equipment grounding connection (earth ground) must be supplied to the unit for safety. Connect the ground
conductor to the green equipment grounding screw identified in the enclosure.
3.0 DPDT RELAY
The DPDT relay utilizes a Fail Safe selector switch. There are 2 positions for this switch, High (H) and Low (L). A
Fail-Safe condition means that the DPDT relay contact positions are set up so that in the event of a power failure
the relay will be de-energized and the contacts will indicate a condition that is deemed safe for the application.
3.1 Fail-Safe High
Fail-Safe High means that the relay will be energized when the paddle is rotating (uncovered) and will de-energize
when the probe is covered. In this mode, a power failure will cause the relay contacts to indicate that the paddle is
covered, whether it is or not.
Figure 7
3.2 Fail-Safe Low
Fail-Safe Low means that the relay will be de-energized when the paddle is rotating (uncovered) and will energize
when the paddle is covered. In this mode, a power failure will cause the relay contacts to indicate that the paddle
is uncovered whether it is or not.
