Chapter Four: Local Operation
General Information
Local operation of the 651 controller is achieved by using the controls on the front panel of the
controller. There are three main software menus, accessed through the front panel that allow you
to configure the system. The menus allow you to select the valve, set the operating parameters,
and set the set point parameters. It is not necessary to open the unit to set any switches.
During Local operation:
•
Press the [ ] key to scroll to the next configuration parameter
•
Press the [ ] key to scroll to the previous configuration parameter
•
Use the Adjust knob to select the desired setting
•
Press any key (other than [ ] or [ ] ) at any time to return to the
default Pressure and Position display screen
The Key Lock Switch on the front panel must be set to Local in order to input any operating
parameters using the front panel controls. Informational requests, however, may still be sent
using RS-232 commands.
Even if you are using local control, it is useful to read Chapter Five: Remote RS-232
Operation . , since requests and responses can always be sent using RS-232 commands. It is also
useful to read Chapter Six: Remote Digital Logic Control, which describes digital logic control
through the Interface connector on the rear panel.
