1.0 INTRODUCTION
The Bin-Master PROCAP I is a point level control used to detect the presence or absence of solids or liq-
uids. The PROCAP I operates on the capacitance principle and incorporates a "Quick Set" feature to sim-
plify 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.
2.0 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:
1. Delrin Sleeved Stainless Steel: 250 Deg. F
2. Teflon Sleeved Stainless Steel: 500 Deg. F
3. Flush Mount (Polyethylene): 180 Deg. F
4. Flush Mount (Teflon): 450 Deg. F
5. Bare Stainless Steel: 250 Deg. F
6. 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 electri-
cally 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.
3.0 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 utiliz-
ing 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 Fig-
ures 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 rat-
ing 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.
