Controller Ports
The OptiCORE controller has sixteen universal outputs (UO) and
twenty-eight universal inputs (UI). All of the input and output (I/
O) settings are preconfigured from the factory to reflect the facto-
ry unit configuration.A predetermined amount of the controller’s
I/O are field configurable to the factory configurations. See Fig. 3
for typical controller layout.
UNIVERSAL INPUTS
All universal inputs can be set to read voltage, amperage, resis-
tance (temperature), and discrete contact. All inputs are config-
ured via software (Factory Program.) See Table 4 and 5 for typical
universal inputs.
NOTE: The universal inputs and analog outputs are
preconfigured at the factory for each factory option package
for the 62X series. Inputs UI-2, UI-4, UI-10, and UI-11 are set
to read 0 to 10 V. All other UIs are set to read resistance
(temperature) and dry contacts. Outputs UO-01, UO-02, UO-
04, UO-05, and UO-06 are set to output voltage. Outputs U-7
(Compressor modulation via Unloader (Digital compressor, 3-
18 tons) or VFD (Variable Speed compressor, 20-55 tons). See
Tables 4 and 5 for default controller configuration.
