SIGNET HBS CHARGER
Test Equipment Required for Troubleshooting
• Digital Multi Meter (DMM).
• Clamp on DC ammeter to measure up to 20-Amps.
Important Notes and Instructions
• This troubleshooting guide assumes a familiarity with the use of a digital multimeter including, voltage tests, continuity
tests, and diode testing. If you are not familiar with any part of these tests, refer testing to a qualied technician.
• Make sure that the AC electrical outlet used is in good working condition.
• Make sure that the AC voltage at the electrical outlet is the same as the AC voltage specied on the charger nameplate.
• Make sure the batteries are in good condition.
• If the charger exhibits intermittent problems, it must be in the failed mode for troubleshooting
• There are no internally serviceable components in the charger. If the charger has failed then it must be replaced.
SLA batteries must be charged with a charger
congured for SLA batteries. Use of any other
charger will result in damage to the batteries and
premature failure of the batteries.
Denitions:
Volts Per Cell = Voltage for each cell in a battery pack. for example, one 6-volt battery has 3-cells.
Term Value Condition
V1: See Chart FLA batteries
2.383 Volts Per Cell SLA Batteries
V2: 2.08 Volts Per Cell All batteries
A1: 2 to 4 Amps All batteries
All voltages are nominal.
V1: Voltages are temperature compensated relative
to the temperature of the charger at the time the
charge cycle is started.

8 to 14 2.56
14 to 21 2.54
21 to 35 2.52

This charger is rated for 115 VAC or 230 VAC
operation (nominal). When switching from
one input voltage to the other, wait until all
LED’s are off. Switching voltage when any of
the LED’s are on will result in damage to the
charger.

charger will result in damage to the batteries and
premature failure of the batteries.
