OPERATIVE MODES
When the instrument is powered, it starts immediately to work according to the parameters values loaded in its memory.
The instrument behaviour and its performance are governed by the value of the stored parameters.
At power ON the instrument can start in one of the following mode depending on its configuration:
Automatic Mode In Automatic mode the instrument drives automatically the control output according to the parameter
value set and the set point/measured value.
Manual Mode (OPLO): In Manual mode the the upper display shows the measured value while the lower display shows
the power output The lower display shows the power output [preceded by H (for heating) or C (for cooling)], MAN is lit
and the instrument allows you to set manually the control output power. No Automatic action will be made.
Stand by Mode (St.bY): In stand-by mode the instrument operates as an indicator. It will show on the upper display the
measured value and on the lower display the set point alternately to the "St.bY" messages and forces the control outputs
to zero.
We define all the above described conditions as "Standard Display".
As we have seen, it is always possible to modify the value assigned to a parameter independently from the operative
modes selected.
AUTOMATIC MODE
Keyboard function when the instrument is in Auto mode:
Modo Operatore
Allows entry into parameter modification procedures
Allows you to start the "Direct set point modification" function
(see below).
Allows you to display the "additional informations" (see below).
Performs the action programmed by [121] uSrb (
function during RUN TIME) parameter
Additional information
This instrument is able to show you some additional informations that can help you to manage your system.
The additional informations are related to how the instrument is programmed, hence in many cases, only part of this
information is available.
1.
When the instrument is showing the "standard display" push
followed by a number. This value is the current power output applied to the process. The H show you that the
action is a Heating action while the "c" show you that the action is a Cooling action
2.
Push
button again. When the programmer is running the lower display will show the segment currently
performed and the Event status as shown below:
where the first character can be r for a ramp or S for a soak, the next digit show the number of the
segment (e.g. S3 means Soak number 3) and the twoless significant digits (LSD) show you the status of the two
event (the LSD is the Event 2)..
3.
Push
button again. When the programmer is running the lower display will show the theoretical remaining
time to the end of the program preceded by a "P" letter:
4.
Push
button again. When the wattmeter function is running the lower display will show U followed by the
measured energy..
5.
Push
button. When the "Worked time count" is running the lower display will show "d" for days or "h" for
hours followed by the measured time.
6.
Push
button. The instrument returns to the "standard display".
Note: The additional information visualization is subject to a time out. If no button is pressed for more than 10 second the
instrument comes automatically back to the Standard display..
