OPERATING THE AT10.1

2.3.3. Setting the Equalize Timer

• Press the

EDIT/ENTER

key until the EQLZ HRS REMAINING,

MANUAL TIMER and AUTO EQLZ TIMER indicators light, and the
display flashes the present value of the equalize timer duration in hours.

Press and release the

DOWN

key to increase or decrease the value in

the display by one count, or press and hold the

DOWN

key to scroll

the value in the display upward or downward. When the display shows
the equalize time, in hours, that you want to set, release the

DOWN

key. If you go past the number of hours you want, press the

DOWN

key again to reach the number you want to set.

If you set the equalize time to zero hours, the equalize mode is disabled.

• Press the

EDIT/ENTER

key. The new equalize timer duration is saved

internally. The timer setting works for both the manual timer and the
auto-equalize timer.

If you want to adjust the alarm settings, skip to Section 2.3.4.

If you want to exit the Edit mode now, press the

EDIT/ENTER

key three

more times until the charger returns to normal operation.

2.3.4. Setting the Alarms

After you save the equalize timer setting, the Edit mode automatically
prompts you to adjust the settings of the high dc voltage and low dc
voltage alarms. There is a red indicator light on the front panel of the
AT10.1 for each of the following alarm conditions:

• High DC Voltage
• Low DC Voltage
• DC

Output

Failure

• AC Input Failure
• Ground Fault Detection (+)
• Ground Fault Detection (-)

When an alarm occurs, the indicators will light immediately. The AT10.1
also features a summary alarm relay with one form-C contacts (TB3),
rated 0.5A / 125 Vac/Vdc. If an alarm condition lasts for 30 seconds or
longer, the summary alarm relay contacts transfer, and can be monitored
remotely from TB3. When the alarm condition is corrected, the relay and
all indicators reset automatically. If latching alarms/relays are enabled the
relay will need to be reset manually, see Section 2.2.7 on page 29.

The summary alarm contacts (TB3) also transfer when the AT10.1 detects
certain secondary errors, indicated by codes (E 03, E 04, E 06, E 07, E
08, E 09, E 10, E 12, E 13, and A 01) on the meter display, rather than a
red alarm light. See Section 3.2 on Page 45 for all error and status codes.
