SIGNET HB CHARGER
Operating Instructions and Theory of Operation
The model HB600W® and HB1000W® chargers are designed as
semiautomatic chargers. The charger turns itself on when it is plugged into
the wall outlet and turns off when the batteries are fully charged.
Both the HB600W® and HB1000W® are two stage chargers. The rst stage
is a constant current mode. It Maintains a constant current until the battery
reaches a terminal voltage and then switches to the second stage, constant
voltage. At the second stage the charger decreases the charger current while
holding the batteries at the terminal voltage until the charging cycle is complete.
The charger faceplate has three status LED’s that monitor the charging status.
Refer to the chart and illustration below for the function of these LED’s.
If an error occurs during charging, the charger will beep, and display an error
code by ashing the status LED’s. Refer to the Status LED error code table
later in this section.
