GENERAL DESCRIPTION

The BATTERY SAVER (BS) is a versatile device for the protection of batteries from low voltage.

Versions can be ordered to disconnect a load or start a generator.

The BATTERY SAVER consists of a relay with a voltage sensing circuit and a red light to indicate

operation. It is housed in an anodized aluminum chassis suitable for wall mounting with a terminal

block for up to 10 gauge wire or spade connector.

FEATURES

LOW-VOLTAGE LOAD DISCONNECT (BS1) or

LOW-VOLTAGE GENERATOR START (BS6)

• 25 amp load, 12 or 24 volt

• 15 amp load, 36 or 48 volt

DESIGN FEATURES

• Indicator light

• Input noise suppression

• Reverse polarity protection

• Adjustability; set-point and span

• Indoor wall mount chassis

APPLICATIONS Deep discharge damage to lead acid battery banks is often a major concern, both as a system reliability issue and an economic issue relating to replacement costs of batteries and cycle life based on depth of discharge. The BATTERY SAVER (BS) can reduce damage to expensive batteries by controlling deep discharge. VERSIONS The BS1 can be used as a low-voltage load disconnect (LVD) to automatically turn lights or other non-essential loads off when battery voltage drops too low.

INSTALLATION BATTERY PRECAUTIONS WARNING: Follow all safety precautions of the battery manufacturer. Proper ventilation must be provided for the batteries. Most batteries produce hydrogen gas when charging, which is extremely explosive. Provide adequate battery ventilation. DO NOT expose the battery to open flame, matches, cigarettes or sparks. DO NOT mount the BATTERY SAVER in an unventilated enclosure with the battery, since the BATTERY SAVER relay can generate sparks when switching.

ADJUSTING THE VOLTAGE SET-POINTS The operating voltage set-points can be changed via adjustment screws accessible from the front. On both BATTERY SAVER Models 1 and 6, two pots are provided for adjustment, one for the LVD (or generator start) set-point and one for the SPAN or voltage change before a reset. Equipment required: Variable power supply with meter, small adjustment screwdriver. 1) Disconnect BATTERY SAVER from system.

TROUBLE SHOOTING GUIDE FOR THE BATTERY SAVER BATTERY SAVER MODEL 1 (BS1) - PROBLEM - DEAD BATTERY • POSSIBLE REASON - THE LOAD DISCONNECT RELAY COULD HAVE FAILED If the red light is on, but the load is not disconnected, the LVD relay may have failed. Check for battery voltage at the LOAD (+) and LOAD (-) terminals of the BS1. If there is not voltage at the load terminals when the light is on, the BS1 is operating and the battery is dead for another reason.
