IOTA IQ-TURBO Manuale utente
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.
BULK STAGE - During this state, the charger will operate either at Full Current output or Constant
Voltage output depending on the discharged state of the battery. A discharged battery will dictate
the voltage and force the charger into constant-current operation. As the battery charges, the char-
ger transitions to a constant-voltage operation. This BULK STAGE will continue for 240 minutes. At
this point, the BULK STAGE will switch to the ABSORPTION STAGE.
ABSORPTION STAGE - This state is limited to 120 minutes (2 hours) during which the charger
will operate either at Full Current output or Constant Voltage output depending on the discharged
state of the battery. During Full Current output, the charger is providing its full current rating and will
slowly increase the battery voltage to the “Absorption Stage” voltage. At the end of the 120 minutes,
the charger will revert to the FLOAT STAGE.
FLOAT STAGE - This charge state holds the batteries at Constant Voltage for a period not longer
than seven days. During this state, the charger not only floats the batteries, but it can also provide
load current up to its maximum rating for other loads without depleting the battery capacity. The
FLOAT STAGE will end when either the battery voltage drops below the “Low Trigger” point or at
the end of 7 days when the IQ-TURBO initiates the MAINTENANCE stage to ensure a complete
charged condition. In either situation, the unit exits the FLOAT STAGE and enters the BULK STAGE.
FAULT STATE - If the IQ enters a FAULT state, its circuitry is automatically disabled. In this state,
the functionality of the IQ is completely disabled, the LED will flash irregularly, and the charger re-
verts to a stand-alone FLOAT STATE voltage. The unit will not exit this stand-alone FLOAT STATE,
therefore the unit must be reset by following the steps below.
1. Unplug the charger from its AC source.
2. Disconnect the [+] positive cable from the battery.
3. Wait 30 seconds before reconnecting the input and output. To avoid arcing, it is recom-
mended that the charger be connected to the AC input FIRST before connecting the output
of the charger to the battery*.
*Note that the connection sequence of the input and output covered above is recommended every
time an operator connects the charger to the batteries. However, as long as the charger remains
connected to the battery, periodic unplugging of the AC input does not require this sequence.
The LED indicator will remain lit or flashing when the charger is unplugged or disconnected from
the AC supply (de-energized). During this time, the IQ continues to monitor the battery voltage. If
the battery voltage drops below a pre-determined voltage (Refer to Figure D for predetermined val-
ues), the IQ will automatically initiate the smart-charging cycle once the AC input is re-connected.
IRREGULAR FLASHING LED - If the LED is flashing irregularly or intermittently, then the IQ has
entered a FAULT state due to a voltage irregularity. When this occurs, the IQ must be re-set in order
to resume normal operation. Refer to the FAULT STATE instructions below for re-setting procedures.
