LV 8 0 0 S E R I E S This manual contains the information necessary to ensure a safe and successful installation. Please read and comply with the section on page 9 of this manual pertaining to SAFETY. Doing so will ensure proper operation of the equipment and the safety of all personnel. Before discarding shipping container, please inspect it thoroughly and verify that all parts ordered are accounted for. Sometimes smaller parts become stuck under carton flaps and other packaging materials.
P R E - I N S TA L L AT I O N C O N S I D E R AT I O N S Choosing a Location: (See Figure 2) 1) Material Flow - When selecting a location for the LV800, choose a point in the vessel where the probe will be out of the direct flow of incoming and outgoing material to prevent any mechanical damage that may be caused by the pressure of the flow.
M E C H A N I C A L I N S TA L L AT I O N E L E C T R I C A L I N S TA L L AT I O N Standard, Food Grade and Stub Probe Mounting: (See Figures 3 & 4) 1) Select a mounting location in accordance with the PreInstallation Recommendations. 2) If using a welded fitting, cut a hole into the side/top of the vessel corresponding to the mounting connection (1-1/4” NPT or 3/4” NPT).
Power Input: (See Figure5) The LV800 is designed to accept either 115VAC or 230VAC (factory set). Verify the intended voltage supply is compatible with the voltage configuration indicated on the electronics and the external nameplate. Connect power as shown in Figure 5. Select wire size that can deliver suitable voltage and current for the application.
LV800 Figure 7 Delay: A potentiometer is provided for setting the time delay between the time material is "sensed" (Yellow LED on) and the time the relay contact output changes (Red LED on). Units have a 1turn potentiometer. A clockwise rotation will increase the delay from .25 to 15 seconds. This adjustment minimizes false signals associated with temporary material shifts.
TROUBLESHOOTING MAINTENANCE PROBLEM: Sensor will not sense material CAUSE/SOLUTION: 1) Verify power is applied to the sensor. 2) Verify "Sense Adjust." Reposition adjustment clockwise therefore making the probe more sensitive to "difficult to sense" materials. 3) Verify probe coverage when sensing is expected. The sensor is not designed to be "tip sensitive." Permit significant probe coverage before expecting material sensing. 4) Verify electrical continuity between sensor housing and vessel wall.
