  • Page 3: Introduction

    Pure Sine wave power output intended for use in Emergency Lighting. The Lite-Minder is very efficient. It typically has a steady state loss of just 2 percent of full load while online which makes it ideal for energy saving and green initiatives. It is designed specifically for emergency lighting from the ground up and meets the needs of all lighting loads since it is a pure sine wave output.

  • Page 4: Receiving And Storage

    2.0 Receiving and Storage Inspection The Lite-Minder Central Inverter and batteries are shipped separately. Upon arrival, please inspect the contents to ensure that no shipping damage has occurred. This is especially important with the batteries to ensure that there are no cracks or leaks. If any damage has occurred, notify the shipping carrier immediately and submit a damage claim.

  • Page 18: Event Log

    Indicates the day that the event took place. This is a rolling day number so if the event occurred on DAY 0001, it was on the first day the Lite-Minder was started up. LENGTH Indicates how long the Lite-Minder ran on battery power. This is useful to indicate if there was a power outage or just a glitch in AC power.

  • Page 19: I-Mon (Off Or On)

    PRESS ENTER > TO UPDATE > I-MON VALUE. If the ENTER button is pressed, the connected load current at the output of the Lite-Minder will be stored as the new value.

  • Page 20: Battery Charging Mode

    There will be two distinct clicks of relays as it goes through the self-check sequence. These relay clicks are the Lite-Minder turning on the output relays to check if any voltages are present and then tickling the output with a small voltage to see if short circuits or overloads are present.

  • Page 21: Switched Output

    Since the crest factor is very high on the Lite-Minder, loads that have high inrush currents are quickly up and running. This is very beneficial with normally off loads which seem to be more prevalent with modern lighting and green building design techniques.

  • Page 22: Warranty

    Power mode. 10.0 Warranty There are two separate warranty periods for the Lite-Minder Central Inverter System. The Electronics/Cabinet warranty period is for 3 years from the date of shipment. It is warranted against defects in workmanship and materials under normal and proper use.

  • Page 23: Maintenance And Service

    Lite-Minder automatically performs monthly tests (every 28 days) and keeps a log of all the events and monthly tests in the event log. Lite-Minder has a self-clearing 28 day counter and resets any time the unit transferred to battery power. If on day 14 the unit had a brief power outage, the counter gets reset and 28 days later (pending no other transfers) a monthly test would be performed.

  • Page 24: Battery Replacement

    Please dispose of properly by recycling. TIP – Discharging the batteries by letting the Lite-Minder run on Battery Power can be beneficial for several reasons. First, it verifies that the batteries need replacing if it does not make 90 minutes of discharge time.
