To Order Call Toll Free: ELM-Series Electrolyte Level Monitor Electrolyte Level Monitoring Systems Product Description The ELM-Series is a reliable electrolyte level and temperature monitoring system designed for flooded batteries. Utilizing low cost, easy to install sensors, the system will alarm on low electrolyte level or higher than normal temperature. In the condition of an alarm, the sensors communicate to the system monitor and dry contact alarm(s) activate while simultaneously activating the appropriate alarm LED lights. In the event that four or more cells trigger an alarm state, the monitor will trigger a group alarm in addition to the single alarm. The alarm contacts may be linked in to any facilities management or alarm system for remote monitoring. Product Features • • • • • • • Low cost monitor for electrolyte level & cell temperature monitoring Auto calibrating sensors adjust to battery in seconds Alarm contacts for external alarming LED lights on monitor and sensors for visual alarming on-site or confirmation of no fault status Fast and easy installation, all cabling cut to length based on simple site survey Applicable to any flooded battery system regardless of voltage & amp-hour Temperature monitoring designed for protection against thermal runaway conditions Cost-Saving Benefits The ELM allows for significant savings in maintenance costs for battery sites by reducing the man-power needed to inspect battery electrolyte levels. Per NERC Standard PRC-005-2, no periodic on-site inspection of cell electrolyte level is required when remote electrolyte level monitoring with alarming is utilized. Installation to Battery Cells Sensor Installation ELM Sensor with Mounting Cradle Installation of the ELM sensors is simple and fast. Sensors are daisy chained together via provided, pre-cut ribbon cable. All required materials for installation are provided. Each ELM sensor is installed to the front of the battery case via a peel off adhesive.

Sensor LED indicators Each sensor has (3) LED lights. The LED’s provide quick visual cues to determine the condition of specific cells in a battery system. • No Fault - Green LED illuminated when the sensor is powered on and no fault is detected • Level - Red LED illuminates red when the sensor detects the electrolyte level is low • Temperature - Red LED illuminates when temperature exceeds set threshold Sensors Installed to Level Line on Flooded Cells Technical Specifications Battery Types: Temperature Alarm Activation: Level Accuracy: Input Voltage: Output Relays Compatible with all transparent...
