This parameter can be programmed as :
=SE: The active Set Point is modifiable while the alarm thresholds are not modifiable
=AE :The active Set Point is not modifiable while the alarm thresholds are modifiable
=SAE: Whether the active Set Point or the alarm thresholds are modifiable
=SAnE: Whether the active Set Point or the alarm thresholds are not modifiable
2.4 – CONTROL STATE
The controller can behave in 3 different ways : automatic control
(rEG),
control off
(OFF)
and manual control
(OPLO).
The instrument is able to pass from one state to the other :
- From the keyboard selecting the desired state from the main selection menu.
- From the keyboard using key “U”; properly programming par. “USrb” (“USrb” = tunE; “USrb” = OPLO; “USrb” = OFF) it’s
possible to pass from “rEG” state at the state programmed on the parameter and vice versa.
- Automatically (the instrument swaps into "rEG" state at the and of the autotuning execution)
At the switching on, the instrument automatically assumes the state it had at the switching off.
AUTOMATIC CONTROL (rEG)
– The automatic control is the normal functioning state of the controller.
During the automatic control it’s possible to visualize the control power on the display pushing key “UP”.
The range of the power values goes from H100 (100% of the output power with reverse action) to C100 (100% of the output
power with direct action).
CONTROL OFF (OFF)
– The instrument can be swapped into the “OFF” state, i.e. the control and the relative outputs are
deactivated.
The alarm outputs are instead normally working.
BUMPLESS MANUAL CONTROL (OPLO)
– By means of this option it’s possible to manually program the power percentage
given as output by the controller deactivating the automatic control.
When the instrument is swapped into the manual control the power percentage is the same as the last one supplied and
can be modified using keys “UP” and “DOWN”.
Likely in the case of the automatic control, the programmable values are comprised from H100 (+100%) to C100 (-100%).
To return into the automatic control, select "rEG" in the selection menu.
