8.5.2 Controller in the manual mode
In manual mode, the user can manually control the controller outputs. The
controller outputs can be controlled in two ways:
• Entry of a numerical value: Using the "Manual entry" button,
the user can open a dialog to enter a fixed numerical value for the output.
• Jogging mode: Pressing and holding the arrow buttons sets the output to
±100 % or the corresponding digital controller output to "on"
depending on the controller configuration. After the button is released, the
output level returns to 0 % or the corresponding digital controller output level
back to "off". This function is used to operate actuators (e.g. solenoid valves,
dosing pumps or motorized positioners) manually. To protect the actuators,
the output does not change abruptly when the button is pressed, but rather
in a continuous manner.
It is also possible to specify a manual output level in the configuration in order
to ensure that a "safety output level" is generated when changing to the manual
mode.
The manual output level is preset in the controller configuration.
