Inputs Setup

The High Pressure CO2 application has the ability to assign all inputs to be any of the possible options for
an analog input in the application. The analog inputs will have offsets available while the digital inputs will have
a polarity option. All input will use physical local input and have a network input from the E2 for backup if avail-
able. The default input configuration is:
Inputs
Pb1 Temperature-Outlet Gas Cooler (T1)
Pb2 Pressure-Outlet Gas Cooler (P1)
Pb3 Pressure-Receiver (P2)
TBD Temperature-Bypass Outlet Gas Cooler (T2)
DI1 Reclaim Setpoint Shift (Digital Input) (HTR)
Enable Application/Emergency Shutdown (Digital Input
DI2
(Enable)
DI3 Control Temp Selector (Digital Input) (CTS)
Table 4-1 - High Pressure CO2 Controller Inputs
The application can use a local or E2 network value if online, but the local value will have priority over the
network value. However, if any sensor is in failure mode, its corresponding network value will be used. If no
network value is available, refer to
The input assignment will be available from the Visograph local display and the E2.
4.1.1 Wiring Analog and Digital
Inputs
The analog inputs are located on the same connector
terminal as the controller power supply. Pay attention to
the input commons as they are share on terminal 13 (PbC)
for temperature probe and terminal 14: Voltage Common
(-) for pressure transducer.
CAUTION: Terminal 14 is labeled
Voltage Common (-) for use as common and
should NOT be earth chassis grounded.
