Note: This menu item is also located later in the manual under the
Section 1 – 9120 Configurator Menus
section
.
The 9120 controller has two analog inputs. Each of the inputs comes with a factory default configuration dependent on
the application (refer to PVT type under the
Furnace Setup
section). It can be modified prior to shipment to your facility
or in the field by a technician or qualified/trained person with the proper security code.
Analog Input Terminals
Analog Input 1 – terminals 31 and 32
Analog Input 2 – terminals 29 and 30
Parameter Definitions
Input Type
The thermocouple type for most applications can be modified depending on your specific needs. Please note that in some
applications, some of the inputs DO NOT allow the user to modify the Input type.
Note: Before changing the input type,
make sure to set the appropriate jumpers, if necessary
.
The jumper will need to be manually changed on the input board
before changing the input type to a 10:1 setting (non-thermocouple types)
. To change the Input type, first select which
input you want to change by selecting it in the pull-down menu just below the main menu list. Clicking on the Value will
display an input box, and then you can use the pull-down menu to select the desired parameter. Once selected, click
OK
and the displayed Input type under Value will be the current type.
