BINMASTER 730-0528-EX Rotary Level Indicator
INTRODUCTION
The BinMaster 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 ( 2 RPM on 24 VDC Model). 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.

Introduction
The BinMaster BMRX is a rotating paddle-style level sensor that provides
reliable point-level detection for bulk solids, including powder, pellet, and

Installation
- Location and Mounting
1. Locate and cut a hole in the top of the bin to fit the outside diameter of 1-1/4 pipe coupling (1.950).
2. Position the coupling halfway into the bin and weld it.
3. Turn the unit so that the conduit opening is in the desired location.
4. Add a 1/4 extension pipe to the desired length with a standard 1/4 coupling on the bottom end.
5. Cut a 1-1/4 support pipe approximately 4 inches shorter than the overall length of the 1/4 pipe shaft when used with a flexible coupling.
6. Insert the 1-1/4 pipe into the coupling and tighten it.
7. Insert the paddle into the 1/4 coupling and drill holes for lock pins.FAQ

SAFETY
SAFETY SUMMARY
- Review the following safety precautions to avoid injury and prevent damage to the equipment.
- 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 codes.
- Use electrical wire that is sized and rated for the maximum voltage and current of the application.
- Properly ground the enclosure to an adequate earth ground.
- Observe all terminal and relay contact ratings as called out on the nameplate and in the installation manual.
- Ensure that the enclosure cover is in place and secured tightly during normal operation.
- In potentially wet environments thoroughly seal all conduit entries.
- If this product is used in a manner not specified by the manufacturer, the safety protection could be compromised.
Safety Terms and Symbols
- WARNING: Warning statements identify conditions or practices that could result in injury or loss of life. Risk of electrical shock.
- CAUTION: Caution statements identify conditions or practices that could result in damage to this product or other property.
INSTALLATION
Location and Mounting
- TOP MOUNT (For mounting plate options see Figure 4 on page 6)
- Locate and cut hole in top of bin to fit outside diameter of 1-1/4” pipe coupling (1.950”).
- Position coupling halfway into bin and weld.
- Turn unit so the conduit opening is in desired location.
- Add 1/4” extension pipe to desired length with standard 1/4” coupling on bottom end.
- Cut 1-1 /4” support pipe approximately 4” shorter than overall length of 1/4” pipe shaft when used with flexible coupling.
- Insert 1-1/4” pipe into coupling and tighten.
- Insert paddle into 1/4” coupling and drill holes for lock pins.
- SIDE MOUNT (For mounting plate options see Figure 5 on page 6)
- Locate and cut hole in side of bin to fit outside diameter of 1-1/4” pipe coupling.
- Weld on half of standard 1-1/4” pipe coupling to bin wall flush with inside of bin.
- Insert hub into coupling and turn until conduit opening is in blown position.
- Screw paddle into place and replace lock pin.
- Shaft and paddle should be shielded in low level mounting when subjected to material flow.
- For side mount, a solid coupler is recommended.
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.
Input Power and Field Wiring
The BMRX is available in AC and DC Models. The AC Models are available to be
powered 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 qualified 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.
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.
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.
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.
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.
