Iota IQ4 Equalizer Installation & Manual

The IOTA IQ-EQUALIZER Charge Controller installs
by simply plugging the IQ cord into the Dual Voltage
jack located on the DLS* (Refer to Figure A). The
IOTA IQ-EQUALIZER circuitry is then automatical-
ly engaged. Note: the cord provided is specifically
designed for use with the IOTA IQ-EQUALIZER. Do
not use the IOTA IQ-EQUALIZER with any cord other
than one supplied with the unit.
Smart Charge Controller
OWNER’S MANUAL
The IOTA IQ-EQUALIZER Charge Controller is designed for equalizing batteries to confidently
achieve the fullest charged condition for flooded lead acid batteries and optimize life of the battery.
Inserting the IOTA IQ-EQUALIZER manually forces the DLS Charger to deliver a enhanced Bulk
charge for a set 120 minutes to replenish batteries quickly and completely. After the IQ-EQUAL-
IZER completes its BULK charge stage, it drops to the FLOAT stage for an extended period to
prevent over-charging of the battery. If further equalization is required after the initial 120 minutes,
simply remove and re-insert the IQ-EQUALIZER to re-initialize the process. ATTENTION: While
the IQ-EQUALIZER is designed to accommodate most flooded lead acid batteries, always refer
to the manufacturer’s specifications for your battery’s allowable charging parameters.
IMPORTANT: BATTERIES MUST BE FULLY CHARGED BEFORE EQUALIZING.
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-EQUALIZER will initiate a Bulk Charge
phase. When the IQ-EQUALIZER is in the Bulk Charge mode, the green LED indicator will flash
rapidly (approx. 2 flashes per second). When the Bulk Charge is complete, the IQ-EQUALIZER
will begin the Float Charge phase and the LED will remain lit (no flashing). Refer to Figure B for
Charge Stage descriptions.

RE-INITIALIZE
The Bulk State charges the battery at the
full-rated output of the charger for 2 hours to
achieve a full and complete charge.
After the Bulk State completes, the IQ drops to
the Float state for an indefinite period of time
to prevent over-charging the battery.
If further equalization is required, remove the
IQ-Equalizer and re-insert to re-initialize the
Equalization process.
