DCM6-L
The DCM6-L is designed for use with 2-volt jars. It can operate up to a maximum power supply voltage
of 12 volts between the white and brown wires. Unlike previous DCMs, the white and blue must be at
the same DC voltage (connected to the same cell terminal post). Note the DCM6-L will not power up,
flash the LEDs and play its startup song until the white, blue and brown wires are connected.
The DCM6-L cannot measure Ripple Voltage. A DCM6-R will be required to measure Ripple Voltage on a
system utilizing DCM6-L units.
The DCM6-L has a lower quiescent current than previous DCMs and so must not be mixed on the same
string of cells, it can however operate on the same fiber optic loop as previous DCM models.
