The IOTA IQ-AGM Charge Controller installs by sim-
ply plugging the IQ cord into the Dual Voltage jack lo-
cated on the DLS* (Refer to Figure A). The IOTA IQ-
AGM circuitry is then automatically engaged. Note:
the cord provided is specifically designed for use
with the IOTA IQ-AGM. Do not use the IOTA IQ-AGM
with any cord other than one supplied with the unit.

The
IOTA IQ-AGM
Charge Controller is designed for automatic charging control for DLS Battery
Chargers with AGM battery applications, providing enhanced battery charging and maintenance.
The IOTA IQ-AGM allows the DLS Charger to operate as an automatic “smart charger” that gives
the customer the benefit of automatic Bulk/Finish, Float, and Maintenance cycles. Multi-stage
charging with the IQ-AGM increases the charging capacity of the DLS charger, decreases the
charge time, and ensures a maintained and full battery charge. The IOTA IQ-AGM monitors the
battery at all times. If the DLS voltage remains in the Float stage for seven days, the IOTA IQ-AGM
will automatically initiate the Maintenance Cycle for a predetermined time to help maintain the
battery, and then resume Float Stage charging.
ATTENTION: While the IQ-AGM is designed
to accommodate most AGM batteries, always refer to the manufacturer’s specifications
for your battery’s allowable charging parameters
.
INSTALLATION
The LED Indicator on the IQ informs the user of the DLS charging state and the battery charge
status. When first activated, the IQ will read the number of cells in the battery and indicate the
voltage of the battery through a number of flashes.
Refer to Figure C.
LIT/FLASHING LED
- After detecting the battery, the IQ-AGM will initiate a Bulk/Finish Charge
phase. When the IQ-AGM is in the Bulk/Finish Charge mode, the green LED indicator will flash
rapidly (approx. 2 flashes per second). When the Bulk/Finish Charge is complete, the IQ-AGM
will begin the Float Charge phase and the LED will remain lit (no flashing). Refer to
Figure B
for
Charge Stage descriptions.

MAINTENANCE
The Bulk State charges the battery at the
full-rated output of the charger, reducing
the time it takes to charge the battery, then
holds it for a predetermined ‘finishing’ period.
Once the battery has been fully charged,
the Float State maintains a full charge to the
battery, and reduces the chances of “gassing.”
If the battery has remained in the Float State for
7 days, the IQ automatically provides reinitiates
a bulk charge to ensure the battery remains in a
completely charged condition.
