PSV Battery Guard

PSV Chassis are generally supplied with a DC switching isolator fitted by the manufacturer. PSV Battery Guard has been designed to be fitted in series with any of these isolators either negative or positively biased. Approved by Volvo, Dennis, & Scania VCA approved to 95/54 EC Key Features •Guarantees starting power •Manual Battery Isolator •Fully waterproof ECU •Delphi Packard waterproof connectors •Oil switch/engine run protection •Switches positively or negatively biased isolators •Audible warning/digital speech module two minutes prior to auto isolation (optional) •Diagnostic indicator on ECU •Easy installation both OEM and retrospectively •Approved by Volvo and Dennis. Intellitec’s PSV Battery Guard has been specifically engineered for the bus and coach market. Most PSV chassis are fitted with a DC isolator as standard and we utilise the chassis isolator to effect low voltage automatic isolation using the PSV Battery Guard ECU in series with the existing isolator. The PSV Battery Guard constantly monitors the available battery voltage when the engine is not running, and if the battery voltage drops below 24.1 (12.1v) a voltage sensitive timer in the ECU is triggered. If the battery voltage remains below 24.1v (12.1v) uniformly for two minutes, the PSV Battery Guard ECU produces an output that drives the warning buzzer included in the kit, or our own digital speech module which says “ Warning Low Battery, Please Start Your Engine”. Should the available battery voltage remain below 24.1v (12.1v) uniformly for four minutes, the PSV Battery Guard will switch the chassis isolator off to guarantee starting power. At this stage there will be no power for ignition, so the driver must press the flashing reset switch and start his engine. The PSV Battery Guard ECU has a built-in diagnostic feature, in the form of an LED indicator which is included on the module to help diagnose any system problems. This LED will illuminate with the engine running and will flash during countdown, prior to isolation. Part No’s.
