IOTA IQ-TURBO Charge Controller
INTRODUCTION
The IOTA 1Q-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 1OTA 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 1Q-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 IOTA IQ-TURBO Charge Controller installs by simply plugging the IQ cord into the Dual Volt age jack located on the DLS 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 1OTA IQ-TURBO with any cord other than one supplied with the unit.
OPERATION AND LED INDICATOR REFERENCE
The LED Indicator on the 1Q informs the user of the DLS charging state and the
battery charge status. When first activated, the 1Q will read the number of
cells in the battery and indicate the voltage of the battery through a number
of flashes.
LIT/IFLASHING LED-After detecting the battery, the 1Q-TURBO willinitiate a Bulk Charge phase. When the lQ-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 1Q-TURBO will begin the Float Charge phase and the LED will remain lit (no flashing). Refer to Figure B for Charge Stage descriptions.
CHARGING STAGE DESCRIPTIONS
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 1Q-TURB0 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 1Q enters a FAULT state, its circuitry is automatically disabled. In
this state, the functionality of the 1Q is completely disabled, the LED will
flash iregularty, 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.
- Unplug the charger from its AC source.
- Disconnect the [+] positive cable from the battery.
- Wait 30 seconds betfore 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.
