1. INTRODUCTION
The Bin-Master PROCAP I is a point level control used to detect the presence
or absence of solids or liquids.
The PROCAP I operates on the capacitance principle and incorporates a “Quick
Set” feature to simplify calibration. The PROCAP I includes switch selectable
Fail-Safe output contacts and “Probe Shield” technology for ignoring material
build up.
Upon installation the PROCAP I 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 CAP I has an adjustable time delay for monitoring covered or uncovered conditions.
2. APPLICATIONS
For applications in pressurized vessels up to 500 PSI, the PROCAP I should be mounted with the 3/4″ or 1 1/4” stainless steel threads. When the PROCAP I is used in liquid applications the stainless steel threads must be used to insure a proper seal.
Process temperatures for the various probes are:
- Delrin Sleeved Stainless Steel: 250 Deg. F
- Teflon Sleeved Stainless Steel: 500 Deg. F
- Flush Mount (Polyethylene): 180 Deg. F
- Flush Mount (Teflon): 450 Deg. F
- Bare Stainless Steel: 250 Deg. F
- Flexible Extension: 250 Deg. F
The Delrin or Teflon sleeved stainless steel probe should be used when mounting the PROCAP I In a highly corrosive atmosphere. Confirm that the sleeve material is rated for use in the corrosive nature of the application. Bare metal Stainless Steel probes are suitable for granular or liquid material that is not electrically conductive. For electrically conductive material, in some applications, a coated (insulated) probe may need be used for the unit to effectively sense the material. Contact BinMaster if there are any questions about which probe to use for a specific application.
3. INSTALLATION
3.1 Location and Mounting
The probe should be located out of the direct flow of material. The PROCAP I
is designed to mount utilizing either a 1 1/4″ NPT coupling or 3/4″ NPT
coupling. When the PROCAP I is used with the flush mount probe, the flush
mount probe mounts directly to the vessel wall using a 7″ diameter bolt
circle. Refer to Figures 1.1 and 1.2 for illustrations on installation,
mounting options, and different probe combinations.
3.2 Input Power and Field Wiring
The PROCAP I can be powered from either an AC or a DC power source with a
voltage range from 24 up to 240 volts. The power source can be either grounded
or ungrounded. If powered from a grounded source the grounded circuit
conductor should be connected to the N terminal. In this way the ungrounded
circuit conductor is fused on the circuit board. A disconnecting means should
be provided to disconnect incoming power to this device. 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 degrees C 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
70 degrees C . Installation shall be done by qualified personnel.
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. A green ground screw is provided in the enclosure for connection of an equipment grounding conductor as shown in the figure above. This unit uses earth ground as a reference for calibration and detecting a covered or uncovered condition. Therefore, the vessel in which the PROCAP I is mounted must be made of metal, or a suitable metal ground plate must be installed where the PROCAP I is mounted.
4. 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.
4.3 Fail-Safe Low
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.
5. CALIBRATION
The PROCAP I 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 in the desired sensitivity. Refer to FIGURE 2.1 for the location of these potentiometers on the printed circuit board.
NOTE: Accurate calibration requires that the appropriate probe is attached to the PROCAP I 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 CAP II senses a covered
probe condition with your material.
5.2 Calibration Procedure
WARNING: During Calibration, this unit will need to be energized. Care should
be taken to not come in contact with any live voltage in the area around the
terminal blocks and fuse!
CAUTION: The Calibration potentiometers are delicate electronic devices, do
not use excessive force when adjusting.
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: 1/16 turn
MEDIUM sensitivity: 1/8 turn
LOW sensitivity: 1/4 to 1/2 turn
NOTE: It may be convenient to think of the FINE potentiometer as a clock face and envision the distance between consecutive hour numbers. Turning the FINE potentiometer clockwise one hour position past the point at which the COVERED indicator just turns OFF would provide a high sensitivity setting. Two-hour positions past that point would provide a medium sensitivity setting..
5.3 Sensitivity Selection
6. EXTERNAL VIEW LED
PROCAP I models include an external view LED. PROCAP I X models do not have an
external view LED.
This LED provides an externally visible status indication for the PROCAP I.
When this LED is flashing, it indicates a normal Uncovered condition. When
this LED is ON steady, it indicates a Covered condition.
When this LED is OFF, it indicates a power failure or fault condition. This external LED is affected by any time delay set for the relay contacts.
7. TIME DELAY
The PROCAP I has two single turn adjustable time delay potentiometers. The Delay potentiometer labeled UNCVR is for applying a time delay on going from a covered indication to an uncovered indication. The Delay potentiometer labeled CVR is for applying a time delay on going from an uncovered indication to an covered indication. Each potentiometer can be set for a time delay of up to approximately 30 seconds.
This time delay affects the relay contacts and external LED only. The internal Covered LED will immediately respond to a change in covered or uncovered condition regardless of the time delay setting. Minimum time delay is when the DELAY potentiometers are set fully counter-clockwise. (Refer to the Figure below for the location of the DELAY potentiometers.) Maximum time delay is with the DELAY potentiometer set fully clockwise.
