Part number: 00‐01118‐000
The Battery Guard® 1000 provides a solution for protecting your batteries from discharging to a level that might
damage your batteries or to a level that prevents the vehicle from being started. The Battery Guard® 1000
constantly monitors the voltage level of the battery to determine the level of charge. When the voltage drops
below the low voltage threshold for a specified duration of time, the Battery Guard® 1000 will automatically
disconnect the battery from the system load, protecting the battery from excessive discharge.
If the Battery Guard 1000® senses a charging potential for a specified duration of time, then it will automatically
reconnect the system load. This condition usually occurs when a charging device is connected to the battery or
the engine is running.
Connecting and Disconnecting the System Loads
The Battery Guard® 1000 accepts a momentary switch input signal. This switch allows user control to manual
disconnect or reconnect the system loads at the user’s discretion. Simply push and release the pushbutton and
the Battery Guard® 1000 will switch states. Keep in mind, the device has a built‐in state change delay of 5
seconds to prevent constant cycling of the disconnect.
Note: If the user chooses to disconnect the system manually, the Battery Guard® 1000 will not automatically reconnect if it
senses charging.
Alarm indication
An alarm output is used to provide the user with valuable information about the state of the disconnect. This is a
high side output alarm that is limited to 300 mA. When used with Intellitec’s Battery Guard Switch (11‐01085‐
001), this output is tied to an LED indicator.
Solid On – Indicates that the system loads are connected, and the battery voltage is above the low voltage
threshold.
Flashing at ½ Hz – Indicates that the system loads are connected, and the battery voltage is below the low
voltage threshold.
Solid Off – Indicates that the system loads are disconnected.
