General Information
1.1
The FP-08879 Digital Voltage Sensitive Relay (DVSR) provides a plug-in solution for DC power
supply monitoring and battery isolation.
automatically isolates the incoming power supply when the incoming power drops below an
ideal operating voltage. This avoids deep discharge of batteries.

- Page 2 DVSR will remain in this mode until power is disconnected. Automatic Cutoff Once the FP-08879 DVSR has determined the operating voltage, it will monitor the incoming power supply. The incoming power supply must drop below operating voltage continuously for 4 seconds before the DVSR will automatically cut off the incoming power supply.
- Page 3 2. The machine MUST NOT be running. 3. Unplug the Power supply to the FIP. 4. Unplug the FP-14016 Battery Lead from Battery Pack and plug into FP-08879 DVSR. The DVSR requires a minimum of 5 seconds to allow sampling of the incoming power supply, to determine operating voltage.
- Page 4 Rev 1.0 Operation The FP-08879 DVSR operates when the unit is installed and the Main power is active. Should the main supply fail or drop below operating volatage, the module automatically cuts off the primary power supply. When the primary supply has been connected the LED will illuminate to indicate that the primary power supply is available.
