Analog Input Setup
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

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.
