INTRODUCTION
The Bin-Master PRO III is a point level control used to detect the presence or absence of solids or liquids.
The PRO III operates on the capacitance principle and incorporates a "Quick Set" feature to simplify calibration. The PRO III includes switch selectable Fail-Safe output contacts.
Upon installation the PRO III is set up with the probe uncovered. The "Quick Set" feature allows simple
setup and calibration of the unit to achieve low, medium, or high sensitivity settings. The PRO III has an
adjustable time delay for monitoring covered or uncovered conditions.
2.0
APPLICATIONS
For applications in pressurized vessels up to 1500 PSI, the PRO III should be mounted with the 3/4" stainless steel coupling.
Application temperatures for the various probes are:
1. Delrin Sleeved Stainless Steel:
2. Teflon Sleeved Stainless Steel:
3. Flush Mount (Polyethylene):
4. Flush Mount (Teflon):
5. Bare Stainless Steel:
250 Deg. F
500 Deg. F
180 Deg. F
450 Deg. F
250 Deg. F
Bare metal stainless steel probes are suitable for granular or liquid material that is not electrically conductive. For electrically conductive material, an insulated probe must be used.

INSTALLATION
3.1
Location and Mounting
The probe should be located out of the direct flow of material. The PRO III is designed to mount utilizing
either a 3/4" NPT coupling or 1 1/4" NPT coupling. Refer to Figures 1.1 for illustrations on installation and
mounting options.
3.2
Input Power and Field Wiring
The PRO III is available in 115 VAC and in 230 VAC models. Before applying power check the supply voltage rating on the nameplate of the PRO III to confirm that you have the correct voltage rating for your
power supply. Field wiring should conform to all national and local electrical codes and any other agency
or authority having jurisdiction over the installation.

NOTE: IF ONE OF THE SUPPLY CONDUCTORS IS A NEUTRAL CONDUCTOR, THEN IT SHOULD BE CONNECTED TO TERMINAL “L1”.
3.3
Grounding
An equipment grounding connection (earth ground) must be supplied to the unit for safety and to insure
proper operation of the unit. This unit uses earth ground as a reference for calibration and detecting a covered or uncovered condition. Therefore, the vessel in which the PRO III is mounted must be made of
metal, or a suitable metal ground plate must be installed where the PRO III is mounted.

FAIL-SAFE SELECTION
4.1
Description
A Fail-Safe condition means that the 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. (Refer to FIGURE 2.1 for the location of the Fail-Safe selection switch.)
4.2
Fail-Safe High
Fail-Safe High means that the relay will be energized when the probe is 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
probe is covered whether it is or not.

Fail-Safe Low means that the relay will be de-energized when the probe is uncovered and will energize
when the probe is covered. In this mode, a power failure will cause the relay contacts to indicate that the
probe is uncovered whether it is or not.

CALIBRATION
The PRO III Quick Set calibration uses two single turn potentiometers making calibration very simple. One
potentiometer labeled COARSE is used to compensate for the capacitance of the empty vessel. The other
potentiometer labeled FINE is used to set up the desired sensitivity. Refer to FIGURE 2.1 for the location
of these potentiometers on the printed circuit board. A tool for adjusting the COARSE and FINE potentiometers is provided inside the top cover of the PRO III. The cover has a convenient clip for storing the tool
so it will always be available.
NOTE: Accurate calibration requires that the appropriate probe is attached to the PRO III and the
unit installed in the vessel. The probe must be UNCOVERED and material well below it.
5.1
Calibration Verification
Following calibration adjustment, the sensitivity setting that you have selected should be checked by verifying that the PRO III senses a covered probe condition with your material.
5.2
Calibration Procedure
1. Turn both the COARSE and FINE potentiometers fully counter clockwise (CCW). The internal COVERED indicator light should be OFF.
2. Turn the COARSE potentiometer slowly clockwise (CW) to the point where the COVERED indicator
light just turns ON and stays on.
3. Turn the FINE potentiometer slowly clockwise (CW) until the COVERED indicator light just turns OFF.
(If the COARSE potentiometer has been carefully adjusted, this should occur when the FINE potentiometer is between the 8 and 10 O'clock position.) Now continue to turn the FINE potentiometer clockwise (CW) to the desired sensitivity setting.
HIGH sensitivity:
MEDIUM sensitivity:
LOW sensitivity:
1/16 to 1/8 turn (1 to 3 picofarad)
1/8 to 1/4 turn (3 to 6 picofarad)
1/4 to 1/2 turn (6 to 12 picofarad)
NOTE: It may be convenient to think of the FINE potentiometer as a clock face where the distance
between consecutive hour numbers represent a change in sensitivity of approximately 2 picofarad. Thus
turning the FINE potentiometer clockwise one hour position past the point at which the COVERED indicator just turns OFF would provide a sensitivity of approximately 2 picofarad. Two-hour positions past that
point would provide approximately 4 picofarad sensitivity, etc.

TIME DELAY
The PRO III has a selectable time delay of up to 15 seconds. This is a time delay for the output to change
states from an uncovered to a covered condition and from a covered to an uncovered condition. This time
delay affects the relay contacts only. The internal LED (DS1) will immediately respond to a change in covered or uncovered condition regardless of the time delay setting.
Minimum time delay is when the DELAY is in the 0 position. (Refer to the figure below for the location of
the DELAY jumper.) Maximum time delay is with the DELAY jumper in the 15 position.
