RhinorSD2/XD2
Electric Drum/Pail Level Indicators
E2007 Nordson Corporation Part 1077746A
Description
See Figure 1. The Electric Drum/Pail Level indicators
use proximity sensors to monitor the distance between
the bottom of the follower plate and the base surface of
the bulk unloader frame.
The Empty Drum/Pail Level Indicator sends an
Empty Level signal to the controller when the bulk
unloader crossover moves in front of the empty level
proximity sensor.
The Low and Empty Drum/Pail Level Indicator sends a
Low Level signal to the controller when the crossover
moves in front of the low level proximity sensor. The
target plate prevents the low level proximity sensor
circuit from opening during the downward movement of
the crossover. When the crossover moves in front of the
empty level proximity sensor, the indicator sends an
Empty Level signal to the controller.
Four Drum/Pail Level Indicators are available:
SDrum/Pail Empty
(18 mm and 30 mm Proximity Sensors)
SDrum/Pail Low and Empty
(18 mm and 30 mm Proximity Sensors)
Repair
Repairs consist of replacing the proximity sensors and
setting the Low and Empty Level signals.
WARNING: Allow only qualified personnel to
perform the following tasks. Follow the safety
instructions in this document and all other
related documentation.
CAUTION: To prevent damage to equipment,
personnel performing these procedures must
know how to safely operate the elevator control
valve on the Rhino SD2/XD2 bulk unloader.
NOTE: Read and understand these procedures before
performing repairs. If necessary, contact a local Nordson
representative regarding repairs to this equipment.

Replace a Proximity Sensor
Use the following procedure to replace a
proximity sensor.
1. See Figure 2. Disconnect the control cable (4) from
the proximity sensor (3).
2. Remove the setscrew (2) securing the proximity
sensor (3) to the adjustment plate (1). Remove the
proximity sensor from the adjustment plate.
3. Screw the new proximity sensor into the adjustment
plate (1) until there is a 0.25 in. gap between the face
of the proximity sensor and the crossover bar or
target plate.
CAUTION: To prevent damage to the proximity
sensor, do not overtighten the setscrew.
4. Apply Loctite 242 to the threads of the setscrew (2).
Install the setscrew and tighten until the proximity
sensor is secure. Do not overtighten the setscrew.
5. Connect the control cable (4) to the proximity
sensor (3).
6. Using the Rhino SD2/XD2 bulk unloader
elevator control valve, raise and lower the follower
plate to test the Low and Empty signals.
Set the Low
and Empty Level Signals
Refer to Table 1. The Low and Empty Level signals
are factory set. If desired, adjust the proximity sensor to
change the factory settings.
CAUTION: To prevent damage to equipment,
personnel performing these procedures must
know how to safely operate the elevator control
valve on the Rhino SD2/XD2 bulk unloader.
Perform the Change the Factory Settings procedure
to change the factory settings. Perform the Reset the
Factory Settings procedure to reset the Low and Empty
Level signals back to the factory settings.

Change the Factory Settings
NOTE: The bottom lip on standard drums/pails can vary
and must be taken into consideration when making
adjustments to the empty level proximity sensor. The
Low Level signal can be adjusted to within 1.75 inches of
the Empty Level signal.
CAUTION: If using spacers to adjust the Empty
Level signal setting on 30- and 55-gallon
systems, remove the frame hold-down shoes to
prevent damage to the follower plate seals.
1. See Figure 3. If applicable, remove the hold-down
shoes (1) from the frame (2).
2. Set spacers onto the base surface of the frame as
shown in Figure 4. Using the Rhino SD2/XD2 bulk
unloader elevator control valve, lower the follower
plate onto the spacers.
3. Loosen the screws (3) securing the adjustment
plate (4). Move the adjustment plate until the
applicable proximity sensor LED (5) illuminates.
Tighten the screws (3) securely.
4. If spacers were used, raise the follower plate and
remove them.
5. Repeat steps 2 through 4 for the remaining proximity
sensor if necessary.
6. Using the Rhino SD2/XD2 bulk unloader
elevator control valve, raise and lower the follower
plate to test the Low and Empty signals.
7. If removed, install the hold-down shoes (1) onto
the frame (2).
Reset the Factory Settings
NOTE: See Figure 4. Have spacers of the proper height
on hand before performing this procedure.
CAUTION: Remove the frame hold-down
shoes on the 30- and 55-gallon systems to
prevent damage to the follower plate seals.
1. See Figure 3. If applicable, remove the hold-down
shoes (1) from the frame (2).
2. Set spacers onto the base surface of the frame as
shown in Figure 4. Using the Rhino SD2/XD2 bulk
unloader elevator control valve, lower the follower
plate onto the spacers.
3. Loosen the screws (3) securing the adjustment
plate (4). Move the adjustment plate until the
applicable proximity sensor LED (5) illuminates.
Tighten the screws (3) securely.
4. Raise the follower plate. Remove the spacers from
the surface base of the frame.
5. Repeat steps 2 through 4 for the remaining proximity
sensor if necessary.
6. Using the Rhino SD2/XD2 bulk unloader
elevator control valve, raise and lower the follower
plate to test the Low and Empty signals.
7. If removed, install the hold-down shoes (1) onto
the frame (2).
