## U **No Moving Parts for Long Life** U **Wide Chemical Compatibility** U **Works for Conductive Liquids** The LVC500 Series electronic level controls should be used whenever a liquid level needs to be maintained, such as pumping down an industrial sump, or indicated, such as a holding tank high-level alarm. A system consists of 3 components: (1) cut-to-length threaded electrode rods; (2) single or multi-electrode holder; (3) remote electronic module(s). The LVC500 Series operates on a simple conductance principle whereby a small electrical current is passed through the conductive liquid between 2 electrodes or an electrode and a metallic tank wall. For applications that require a separate start and stop point, a single control module, plus 2 electrodes and a tank reference, is required. When several applications or levels are necessary within a single tank, an a **LVC-N3-SS, SS threaded** electrode is needed for each level (plus tank Z => **multi-electrode assembly shown smaller than** reference), plus a **actual size.** multi-electrode holder Mi. . c “ and a control module for each differential or single-level application. Typically, potable water, condensate, | acids, and waterbased chemicals (inorganic chemicals) have sufficient conductivity. Non-aqueous liquids, such as oils and other hydrocarbons, cannot be measured. ## **Note:** Always treat hazardous areas with respect! If the electrodes or float switch is located in a hazardous area, an intrinsically safe control module must be used. Intrinsically safe controls must be installed by experienced personnel familiar with intrinsic safety wiring, and installation must be in accordance with the National Electrical Code (NEC). The control must be mounted in a non-hazardous location with the wiring to the level probes or float switch going into the hazardous atmosphere. Intrinsically safe wiring must be separated from non-intrinsically safe wiring, and the length of your 14 or 16 gage copper wire must not exceed the specifications listed in the current installation manual. Consult your local electrical code inspector for further details. **1** ## _**Electronics Modules Mounting Assemblies**_ ## U **SPDT Relay Output** U **Fully Field Selectable** U **Transparent Case for Viewing Relay Status** - Low-voltage probe circuit - SPDT relay output - Interface to pumps, valves, or alarm systems - Field-selectable latching/ non-latching operation - Field-selectable high/low alarm, pump-up/pump-down ## **LVC510 Series:** - See-through Lexan[®] case for viewing relay status LED - Plug-in module, socket included - Screw terminal connections for easy wiring ## **LVC512 Model:** - Field-settable sensitivity to match a variety of liquids - Required for distilled water (1 MΩ max) ## **LVC521 Model:** - Open circuit board construction - Low cost, OEM style - Spade terminal connections - Designed to mount on[1] ⁄16" backplate with supplied plastic standoffs - Relay status LED ## **LVC550 Series:** - Intrinsically safe - Approved for Class I and II, Divi sion 1, Groups A through G - 8 A relay output - LVC551: FM approved LVC552: UL approved - Can be used with any non-powered switch closure **==> picture [193 x 170] intentionally omitted <==** **----- Start of picture text -----**

## **Differential Service:** For fill or drain applications. When the liquid rises to the electrode on terminal H, the control energizes, changing the state of the load contacts. The control remains energized until the liquid level recedes below electrode on terminal L. The control then de-energizes, returning load contacts to original state. ## **MOUNTING ASSEMBLIES** ## **Single Electrode:** The LVC-S Series comprises single electrode holders with exposed connection. UL-approved rubber boots are available for connection protection. ## **Inverse Mode:** ## **Shipping Weight:** LVC-S unit, 170 g (6 oz) **Overall Length:** 82.6 mm (3.25") **Multiple Electrodes:** Control energizes with power, changing the state of the load contacts. All other responses are the opposite of the response given by direct-mode operation. Inverse mode is normally used for pump-up or high-level alarm applications. The LVC-N and LVC-F mounting assemblies feature a gasketed, epoxy-coated, die-cast aluminum junction box, and include the proper number of electrode holders. _See chart below for additional information._ ## **SPECIFICATIONS** ## **Electrodes** **Supply Voltage:** 102 to 132 Vac (110 to 132 Vac for LVC552), 50/60 Hz standard; 240 and 24 Vac optional) **Ambient Temperature:** -40 to 65°C (-40 to 150°F) **Switch-Point Hysteresis:** 1.6 mm (±[1] ⁄16") **Relay Time Delay:**[1] ⁄2 second delay on rising level _See chart below for additional information._ The LVC-E electrodes come standard in 316 SS, but are available in a wide range of materials. Electrodes thread into couplings on LVC-S, LVC-N, and LVC-F mounting assemblies. **Electrode Diameter:** 6.35 mm ([1] ⁄4"); 1⁄4" thread length **Electrode Weight:** 0.25 g/mm (0.167 lb/ft) ## **Electronic Modules** ## **Electronics Operation Direct Mode Single-Level Service: Single-Level Service:** For high or low alarms or cutoffs. When the liquid rises to the electrode on terminal H, the control energizes, changing the state of the load contacts. The control remains energized until the liquid level recedes below electrode on terminal H. The control then de-energizes, returning load contacts to original state. |**LVC**
