FRONT PANEL OPERATION
The CN4431 programming menu consists of three blocks— SETUP
MENU, SYSTEM MENU, and FACTORY PRESET MENU. At power up the
controller will be in the operational mode, and process variable (PV)
and setpoint variable (SV) will be displayed. PV is the variable that is
being controlled, and it is not programmable. When setting the para-
meters, turn off the power to the load (operating equipment) to ensure
safety. Allow 30 minutes for the unit to stabilize in terms of temperature,
and to achieve the rated accuracy. Option-related features are
displayed only when the options are used.
