The PBT-CCS-1 float current monitoring system is an accessory to the PowerAgent battery monitoring system. It consists of a current monitoring interface (CMI) unit and a float current monitoring sensor. The system accurately monitors changes in the DC charging current which are precursors of an impending cell failure, as well as AC ripple currents which are indicators of charging system problems. The system also detects reversal of current direction indicative of a discharge condition and provides an alarm indication if a discharge event occurs.
How it works
The float current sensor toroid is installed on a monitored current-carrying conductor. The conductor, which is typically either an interconnection cable or a bus bar, is passed through the aperture of the current measurement sensor. The float current sensor is plugged into a CMI. Multiple PBT-CCS-1 current monitoring systems can be connected to the site control unit’s P-Bus daisy chain using common CAT5 jumpers. Power is supplied to the CMI module over the P-Bus.
The CMI has a user-settable address switch. This switch allows the user to assign one of six P-Bus addresses to the CMI. The CMI has LED’s that indicate the status of the current sensor as well as communications with the site control unit.
