LS-800PVC Series - Continued 3. Number of Actuation Levels and Electrical Specifications Typically, one float is required for each point at which you need a switch action to occur. The number of actuation levels available depends on type of wiring selected. See below. Wiring Color Code Group I Wiring: 1 to 7 Actuation Levels Group II Wiring: 1 to 4 Actuation Levels SPST Switches Group III Wiring: 1 to 3 Actuation Levels LEVEL SWITCHES - MULTI POINT Group IV Wiring: 1 to 2 Actuation Levels Switch (N.O. or N.C.): SPDT Switches 20 VA Wiring Group I Group II Group III Group IV Com.

Actuation Level Dimensions Actuation Level*- Typical L7 Switch actuation levels are determined following the guidelines below. L6 A = 1-1/2˝ (38.1 mm) Minimum distance to highest actuation level. B = 2˝ (50.8 mm) Minimum distance from end of unit to lowest actuation level. C = 3˝ (76.2 mm) Minimum distance between actuation levels. A L5 Notes: 1. Actuation levels are calibrated on descending fluid level, with water as the calibrating fluid, unless otherwise specified. 2. A and B dimensions based on a top mounted unit. 3. Float stops are permanently cemented in place. 4. Tolerance on actuation levels is ±1/8˝ (3.2 mm). 5. Dimensions based on a liquid specific gravity 1.0. L4 L3 L0 (LENGTH OVERALL)** L2 C B L1 * Actuation level distances and LO (overall unit length) are measured from inner surfaces of mounting plug or flange. ** Length Overall (LO) = L1 + Dimension B.
