Power On
The Series C controller’s functional hierarchy
is organized into three distinct
Security Level, Menu System, and Operating Mode.
Please provide the software version number, communications protocol, and the controller’s full model number, when contacting us regarding your controller.
When power is first applied to the Series C, all segments of the LED displays will be momentarily illuminated while the instrument goes through a series of diagnostic checks to verify proper operation. A software version number will then appear in the lower display, followed by a configuration code (upper display) and the communications protocol which is supported (lower display).
IMPORTANT: On initial startup, there is a possibility that outputs may be activated. We recommend placing the unit in Standby mode until you have configured the controller according to your application requirements. To place the controller in Standby, follow this procedure:
1)Press and hold Mode/Enter 
key until a menu label appears in upper display (approximately three seconds).
2)Press Raise 
or Lower 
key until 
appears in the lower display.
3)Press Mode/Enter 
key. (The upper display will
alternate between 
and process value.)
Operations Overview
The user interface of the Series C allows you to use menus to set up the instrument, set the desired security level, change the setpoint, and conveniently change operating modes. Figure 9 on page 15 provides a functional representation of
the user interface and the key presses necessary to perform the basic functions.
