The COR slider tile shows the current state of the COR output: manual OFF, AUTO, or
manual ON. The COR tile must be in the AUTO position for the COR to be operated
under program control. Click on the name of the COR in the tile to configure the COR.
Regardless of the APEX model and user interface in use, the default name of a COR-15
or COR-20 output is
COR_#_1
, where
#
is the AquaBus address of the COR driver. You
may change the name if desired.
ABOUT IQ-LEVEL
IQ-Level is a form of calibration that
allows you to configure the pump’s minimum and
maximum speeds to be optimal for your aquarium. Using IQ-Level is entirely optional
but is highly recommended.
In the next few paragraphs, we will discuss IQ-Level as it should be done for a common
aquarium setup in which the COR is used as a return pump. Other COR uses, such as
closed loop applications, will require different criteria be used for IQ-Level.
Ideally, the pump’s maximum speed will be calibrated so that 100% speed corresponds
to that speed which moves the perfect amount of water
for the tank’s overflow drain(s),
without exceeding the capacity of the overflow or pumping insufficient volume of water
to maintain a constant full siphon drain. This is important to do, as properly setting the
maximum speed of the pumps ensures that the output of the pump will not exceed the
capacity of the overflow and drain system, even if the COR slider on the Dashboard is set
to manual ON.
Ideally, the COR’s minimum speed will be
set with IQ-Level so that when the pump is
running at 1%, the pump does not slow so much that the water in the return piping
drains out backwards. The perfect minimum speed is that speed which just holds the
water column full and in a quiescent state, and does not actually cause water to be
pumped. You would then program to COR to run at that minimum speed during feeding
times and in other situations when no water movement is desired.
