Greenheck Microprocessor Controller (475595 IOM) TAP v2.10 April 2014 (RVE, ERCH-01, ERT-01) - Manual (Page 38)

The pCOe is an I/O module that can be used
to monitor additional statuses within the unit or
provide commands. The pCOe allows the user to
view and control:
• 4 Digital Inputs
• 4 Digital Outputs
• 4 Analog Inputs
• 1 Analog Output
The inputs and outputs can be monitored and manually controlled
either via the controller display or Building Management System. See
Points List for detailed point information.
In order for the controller to communicate with the pCOe, several parameters must be adjusted. If you have a pCOe
installed from the factory, the controller is already set up for communication with the main controller.
Enabling the pCOe in the Main Controller. - To enable the pCOe expansion
I/O module, go to Manufacturer > Configuration. You will have to enter the
Manufacturer password (Default = 1000). Enabling the pCOe expansion module
allows additional screens to appear in other menus (see below).
Viewing pCOe I/O Values. - To view input values, go to the Input/Output menu.
The pCOe I/O values can be viewed on the BMS. The digital and analog outputs
can be changed through the BMS. See Points List for more details.
Configuring the pCOe Analog Inputs. - The analog inputs are grouped in pairs
(Channels B1-B2 and Channels B3-B4). Each pair must be configured as the
same analog input type (Carel NTC, 0/10 VDC, 0/20 mA, 4/20 mA or 0/5 VDC).
To setup the analog inputs:
1. Go to Manufacturer > I/O Configuration > Analog Inputs.
2. Find the pCOe Analog input screens.
3. Select desired channels and input type. If only one channel is to be used,
select the desired channel to prevent nuisance sensor alarms.
If using a non-Carel NTC type, scale the input to match the probe range.
