BEFORE STARTING
SIERRA INSTRUMENTS appreciates your choosing our product for your liquid level or liquid/gas flow
switching application. We are committed to providing reliable, quality instrumentation to our customers.
To ensure the maximum and intended benefit of this instrument, we encourage you to read this brief
operation and maintenance manual in its entirety prior to unpacking and installing the unit.
The following precautions should be noted immediately:
• WHEN INSTALLING YOUR INNOVA-SWITCH™ INTO A PIPE OR VESSEL USE A 1 1/8 INCH
(28.575mm) OPEN-END WRENCH TO TIGHTEN AT THE HEX FLATS OF THE MNPT OF A
STANDARD SWITCH. (IF YOU HAVE A NON-STANDARD SWITCH AN ALTERNATE SIZE
WRENCH MAY BE REQUIRED). DO NOT USE THE INSTRUMENT HEAD TO TIGHTEN THE
SWITCH TO THE MOUNTING PORT. ROTATION OF THE INSTRUMENT HEAD WITH
RESPECT TO THE SENSOR BODY CAN CAUSE INTERNAL WIRING DAMAGE (SEE
FIGURES 1).
•
THE SWITCH BODY MUST BE ORIENTED TO HAVE THE TWIN SENSORS PARALLEL TO
THE LEVEL BEING DETECTED WHEN THE SENSOR IS INSTALLED HORIZONTALLY FOR
POINT LEVEL APPLICATIONS. LIKEWISE, FOR FLOW APPLICATIONS, THE SWITCH
BODY MUST BE ORIENTED TO HAVE THE TWIN SENSORS PERPENDICULAR TO THE
FLOW BEING DETECTED. DUE TO THE PIPE THREAD MOUNTING, IT MAY BE
NECESSARY TO MAKE A TRIAL FIT, ADD OR REMOVE TEFLON TAPE OR OTHER PIPE
THREAD SEALANT, AND REINSTALL TO ACHIEVE A SATISFACTORY SEAL WITH THE
SENSORS PROPERLY ORIENTED. FOR VERTICAL INSTALLATION OF SENSORS FOR
POINT LEVEL DETECTION THE ORIENTATION MAKES NO DIFFERENCE. PROPER
ORIENTATION IS MARKED ON THE SWITCH BODY FOR REFERENCE (SEE FIGURE 5).
• A GROUND WIRE MUST BE ATTACHED TO THE GROUND SCREW LOCATED INSIDE THE
INSTRUMENT ENCLOSURE FOR PROPER OPERATION. FOR CENELEC/CE OPTION THE
GROUND SCREW IS LOCATED OUTSIDE THE BODY OF THE INSTRUMENT ENCLOSURE
(SEE FIGURE 6).
• BE SURE TO APPLY THE PROPER VOLTAGE AS CONFIGURED AT THE FACTORY. DO
NOT APPLY 115 VAC TO 24 VDC VERSIONS OR 24 VDC TO 115 VAC VERSIONS.
(LIKEWISE 230 VAC).
• FOR OPTIMUM OPERATION, CALIBRATION MUST BE ACCOMPLISHED AT ACTUAL
PROCESS TEMPERATURE AND PRESSURE CONDITIONS IN GASES AND AT ACTUAL
PROCESS TEMPERATURE CONDITIONS IN LIQUIDS.
• DO NOT SANDBLAST OR ABRASIVE CLEAN THE SENSING PROBES. THE SENSING
PROBES COULD BE DAMAGED BY ABRASIVES.
• ALL DIMENSIONS GIVEN IN THIS MANUAL ARE IN INCHES (AND MILLIMETERS).
If you have any questions prior to or during installation and calibration, please do not hesitate to call the
factory for assistance. We want to ensure the very best possible installation and operational results for
your benefit.
