1. Product Description
The ELS Electrolyte Level Sensor is a non-invasive level sensor designed for quick installation and easy
set up. This device complies with the NERC PRC-005 requirements for electrolyte level inspection. With
this sensor, you eliminate unnecessary remote site visits. This device will eliminate the required
quarterly inspection of battery electrolyte levels in your battery string.
1.1 ELS Sensor Module System Features
Features for the ELS Sensor module includes:
•Equipped with two RJ11 connectors for system interface and alarm notification
•Front panel status indicators for easy alarm identification and system functional status
•low electrolyte levels
•power loss
•Automatic reset of alarms
•Easily integrates into Vertiv Battery Monitors (UXIM, BDS Series) or Building Management Systems.
1.2 ELSi Interface Module System Features
Features for the ELSi interface module includes:
•Equipped with two Form C relay contacts, (2A at 30Vdc) for system interface and alarm notification
•Front panel status indicators for easy alarm identification
These alarms include:
•low electrolyte levels
•power loss
•system bus integrity
•Automatic or manual reset of alarms
•Easily integrates into Vertiv Battery Monitors (UXIM, BDS Series) or Building Management Systems
Note: Before connecting the ELSi interface module, decide if you want the alarms to be latched or
automatically reset. The ELSi interface module includes a JP1 jumper which is used to automatically
reset the alarms once all the ELS sensor module alarms are cleared. The default on the JP1 jumper is set
to out. This allows all alarms to be latched and will not be reset until you manually reset the alarms on
the ELSi interface module by pressing the button on the right side of the module. All alarms on the ESL
sensor modules must be cleared before resetting the alarm on the ELSi interface module.

1.3 ELS Temperature Control Module (ETCM) System Features
The ELS Temperature Control Module (ETCM) is an optional module for cold climates which includes the
following features:
•Equipped with an ambient temperature sensor to detect uncontrolled cold temperatures for
interruption of false alarm notifications.
•Easy to view and set temperature settings for trigger points to cut off false alarms via a rotary
switch.
•Easily integrates into Vertiv Battery Monitors (UXIM, BDS Series) or Building Management Systems
via the ELSi.
