Iota IQ4-X Manual

The DLS-X features an accessory port
on the fan end of the unit for installing the
IQ4-X Charge Control Module. To install
the IQ4-X, remove the fastening screw on
the top of the port faceplate and detach the
faceplate. Plug the control module into the
port and secure in place using the original
fastening screw. NOTE: the port faceplate
and IQ4-X control module are similar in
appearance. You can recognize the IQ4-X
Charge Control Module by the presence of
the LED indicator on the face.

The IQ4-X Charge Controller offers automatic charging control for DLS-X Battery Chargers,
providing longer and safer use of your system’s battery. The IQ4-X allows the DLS-X Charger
to operate as an automatic 4-stage “smart charger” that gives the customer the benefit of Bulk,
Absorption, Float, and Equalization charging. Multi-stage charging increases the charging ca-
pacity of the DLS-X charger, decreases the charge time while insuring proper and safe battery
charging, and minimizes the possibility of over-charging. The IQ4-X monitors the battery at all
times. If the DLS-X voltage remains in the Float stage for more than seven days, the IQ4-X will
automatically enter the Equalization stage for a predetermined time to help maintain the battery
plates, and then resume float stage charging.
INSTALLATION
The LED Indicator on the IQ4-X informs the user of the DLS-X charging state and the battery
charge status. When first activated, the IQ4-X 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 reading the battery, the IQ4-X will initiate in Bulk Charge phase. When
the IQ4-X 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 IQ4-X begins the Absorption Charge and the
LED indicator will flash at a slower rate (approx. 1 flash per second). If the battery is not in need
of charging, the IQ4-X will begin the Float Charge phase and the LED will remain lit (no flashing).
Refer to Figure B for Charge Stage descriptions.

EQUALIZATION
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 AL1 automatically provides an
equalization charge to dissolve any sulfate layer
on the battery’s plates and to avoid stratification.
