2. OPERATING THE AT10.1 BATTERY CHARGER
2.1. STARTING THE AT10.1
2.1.1. Understanding the startup sequence
The AT10.1 is set up at the factory to work with most common batteries
and loads without further adjustment. When you start the AT10.1 for the
first time, the factory settings (float voltage, equalize voltage, etc.) control
the operation of the charger. You can change the settings after you start
the AT10.1. The
FACTORY SETTINGS
are listed in table on page 25.
The AT10.1 startup routine takes about 5 seconds. The microprocessor
that controls the AT10.1 initializes the charger by reading the settings that
are stored internally. The control circuitry then "soft starts" the AT10.1,
and the dc output voltage and current increase gradually to the rated value.
2.1.2. Checking the installation
Confirm that you have followed the installation
instructions carefully. Check the ac input
supply voltage and the battery voltage, and
make sure they match the information on the
AT10.1 data nameplate.
Verify that the
jumpers on the main transformer (T1) are
correct for your ac supply voltage.
Open the
front panel door and carefully check the battery
polarity at the dc output terminals TB1(+/-).
2.1.3. Starting the AT10.1
When you are sure that all connections to the
AT10.1 are properly made, follow these steps
to start up the AT10.1:
Using the Digital Meter
When you first start the
AT10.1, the meter display
alternates between dc output
voltage and dc output current.
Each reading is held for 2
seconds. Indicator lights to
the left of the display indicate
whether the meter is
displaying voltage or current.
If you want to “freeze” the
meter to display only voltage,
press the
METER MODE
key on the front panel. To
freeze the meter to display
only current, press the key
again. Press the key twice
more to revert to the
alternating display.
•
Turn on (close) the dc output circuit breaker (CB2) first .
•
The digital meter indicates battery voltage only. If the meter display
does not light,
do not proceed . Turn off (open) the dc breaker (CB2).
•
Check all connections and the battery polarity again. Also check the
battery voltage. It must be above 50% of nominal voltage to turn on the
display. If you cannot find the problem, refer to the
Troubleshooting
Procedure in Section 3.1 on page 44.
NOTICE
If you attempt to turn on the dc circuit breaker (CB2) with the battery
connected in reverse polarity, the breaker will immediately trip. Do not
try to close the dc breaker again, since this may damage the AT10.1. If
your AT10.1 is equipped with dc fuses, one or both fuses will blow when
the battery is reversed. Correct the battery polarity before proceeding.
