7.4 Automatic Mode
7.4.1 Keyboard function when the instrument
is in Auto mode
Performs the action programmed by [88] uSrb
(
button function during RUN TIME) parameter.
Allows to enter into parameter modification procedures.
Allows to start the “Direct set point modification” func-
tion (see below).
Allows to display the “additional informations” (see below).
7.4.2 Direct set point modification
This function allows to modify rapidly the set point value
selected by [81] A.SP (selection of the active Set point) or
to the set point of the segment group (of the programmer)
currently in progress.
The instrument is showing the “standard display”.
1.
Push
button.
The upper display shows the acronym of the selected set
point (e.g. SP2) and the lower display its value;
Note:
When the programmer is running, the instrument shows
the set point of the soak currently in execution (e.g. if
the instrument is performing the soak 3 of the program
2, the instrument will show P2.S3).
2.
By
and
buttons, assign to this parameter the
desired value
3.
Do not push any button for more than 5 second or push
the
button.
In both cases the instrument stores the new value and
returns to the “standard display”.
Note:
If the selected set point has not been promoted to the
Operator level, the instrument allows to see the value
but not to modify it.
7.5 Manual mode
This operative mode allows to deactivate the automatic
control and manually program the percentage power output
to applied to the the process.
When the instrument is in manual mode, the upper display
shows the measured value while the lower display shows
alternately the power output [preceded by
H
(for heating
action) or
C
(for cooling action)] and the message
oPLo
(open loop).
When manual control is selected, the instrument starts to
operate with the same power output as the last one supplied
by automatic mode and can be modified using the
and
buttons.
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: 1.
During manual mode, the alarms are operative.
2.
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.
3.
If you set manual modes during auto-tune
execution, the auto-tune function will be aborted.
4.
During manual mode, all functions not related
with the control (wattmeter, independent timer,
“worked time”, etc) continue to operate normally.
7.6 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 shows the measured value while the lower display
alternatively shows the set point and the message “St.bY”.
Notes: 1.
During stand by mode, relative alarms are
disabled while absolute alarms are operative
or not according to the ALxo (Alarm x enabling
during Stand-by mode) parameter setting.
2.
If you set stand by mode during program
execution, the program will be aborted.
3.
Setting the stand by mode during auto-tune
execution, the auto-tune function will be aborted.
4.
During stand by mode, all functions not related
with the control (wattmeter, independent timer,
“worked time”, etc.) continue to operate normally.
5.
When the instrument is swapped from stand by
to auto mode, it automatically starts the alarm
masking, the soft start functions and auto-tune (if
programmed).
7.6.1 Additional information
This instrument is able to show some additional information
that can help managing the system.
The additional information 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
button.
The lower display shows
H
or
c
followed by a number. This
value is the current power output applied to the process.
H
means Heating action while
c
means Cooling action.
2.
Push
button again. The lower display shows the
program page currently selected. Example “PAGE 2”;
3.
Push
button again. The lower display shows the
selected program number. Example: “PrG7”= program 7;
4.
Push
button again. When the programmer is running
the lower display shows the program and the segment
currently in execution.
NOTE
: When linked programs are
running, the program selected and the program in execution
can be different Example: “P7.S1”= program 7 soak 1;
5.
Push
button again. When the programmer is running
the lower display shows the time remaining for this
program to the end of the current cycle.
Example: “12.22” = 12 minutes and 22 seconds;
6.
Push
button again. When the programmer is running
the lower display shows the already made executions.
Example: “E . 5” = 5 executions are already made;
7.
Push
button again. When the programmer is running
the lower display shows the Event status.
Example: “EU.01” => event 1 = 0 - Event 2 = 1;
8.
Push
button again. 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
seconds the instrument automatically returns to the
Standard display.
