57. a Low Alarm or Low Cutoff would be positioned to detect a low water level nearer the bottom of the basin Again signaling is achieved in two ways High Level and Makeup cards react when the water provides a completed circuit or continuity between its sensor and the reference probe The second type of signal is for Low Level detection The Low Level cards react when the water is not present and opens the circuit or disrupts the current flow between its probe and the reference A water level control system can be configured to meet various combination requirements Since one individual circuit card is responsible for each func tion the size and circuitry varies in proportion to the number of operations desired For example a water level makeup control will require a control panel with one circuit relay card and three probes A system configured for water makeup that includes a high alarm and a low alarm will require three circuit cards and five probes one circuit card for the water makeup option one for high operation and one for low Operation Water Makeup Function A system is designed for alarms and or cutoff indication only would not be equipped with the water makeup function The circuitry for water makeup in the LLC control panel provides an indepen dent circuit breaker for direct connection to a 110 120VAC water solenoid valve This added feature allows customer installation without having to provide an additional power circui
