The IOTA IQ-TURBO Charge Controller installs
by simply plugging the IQ cord into the Dual Volt-
age jack located on the DLS* (Refer to Figure A).
The IOTA IQ-TURBO circuitry is then automatically
engaged. Note: the cord provided is specifically de-
signed for use with the IOTA IQ-TURBO. Do not use
the IOTA IQ-TURBO with any cord other than one
supplied with the unit.
Smart Charge Controller
OWNER’S MANUAL
The
IOTA IQ-TURBO
Charge Controller is designed for rapid automatic charging control for DLS
Battery Chargers with flooded lead acid battery applications, providing enhanced battery charging
and maintenance. The IOTA IQ-TURBO allows the DLS Charger to deliver an enhanced Bulk
charge to replenish batteries quickly, in addition to providing Absorption, Float, and Maintenance
cycles. Multi-stage charging with the IQ-TURBO increases the charging capacity of the DLS
charger, decreases the charge time, and ensures a maintained and full battery charge. The IOTA
IQ-TURBO monitors the battery at all times. If the DLS voltage remains in the Float stage for seven
days, the IOTA IQ-TURBO 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-TURBO is designed to accommodate most flooded lead acid 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-TURBO will initiate a Bulk Charge phase.
When the IQ-TURBO is in the Bulk Charge mode, the green LED indicator will flash rapidly (ap-
prox. 2 flashes per second). When the Bulk Charge is complete, the IQ-TURBO 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.
The Absorption State delivers a constant
charge for a set period of time to ensure that
the battery receives a full and complete charge.
Once the battery has been fully charged, the
Float State maintains a full charge to the battery
while minimizing “gassing.”
If the battery has remained in the Float State for
seven days, the IQ automatically provides an
equalization charge to dissolve any sulfate layer
on the battery’s plates and to avoid stratification.
