Direct set point modification
This function allows to modify rapidly the set point value selected by [83] A.SP (selection of the active Set point) or to the
set point of the segment group (of the programmer) currently in progress.

display will show its value.

Manual mode
This operative mode allows you to deactivate automatic control and manually program the percentage power output to
the process. When the instrument is in manual mode, the upper display shows the measured value while the lower
display shows the power output [preceded by H (for heating action) or C (for cooling action)] The MAN LED is lit. When
manual control is selected, the instrument will start to operate with the same power output as the last one supplied by
automatic mode and can be modified using the
In case of ON/OFF control, 0% corresponds to the deactivated output while any value different from 0 corresponds to the
activated output. As in the case of visualization, the programmable values range from H100 (100% output power with
reverse action) to C100 (100% output power with direct action).
Notes:
•
During manual mode, the alarms are operative.
•
If you set manual modes during program execution, the program will be frozen and it will restart when the
instrument will come back to Auto mode.
•
If you set manual modes during self-tune execution, the self- tune function will be aborted.
•
During manual mode, all functions not related with the control (wattmeter, independent timer, "worked time", etc)
continue to operate normally..
STAND-BY MODE
This operative mode also deactivates the automatic control but forces the control output to zero. In this mode the
instrument operates as an indicator. When the instrument is in stand by mode the upper display will show the measured
value while the lower display will show alternately the set point and the message "St.bY".
Notes:
•
During stand by mode, the relative alarms are disabled while the absolute alarms are operative or not according
to the ALxo (Alarm x enabling during Stand-by mode) parameter setting.
•
If you set stand by mode during program execution, the program will be aborted.
•
If you set stand by mode during self-tune execution, the self- tune function will be aborted.
•
During stand by mode, all functions not related with the control (wattmeter, independent timer, "worked time",
etc) continue to operate normally.
•
When the instrument is swapped from stand by to auto modes, the instrument will start automatically the alarm
masking, the soft start functions and the auto-tune (if programmed).
AUTOTUNE (EVOTUNE)
Evotune is a fast and fully automatic procedure that can be started in any condition, regardless the deviation from SP.
The controller selects automatically the best tune method and computes the optimum PID parameters. To activate
