7.3 How to see but not modify the
“limited access parameters”
Sometime it is necessary to give to the operator the possibility
to see the value assigned to the parameter promoted in the
Limited Access level but it is important that all changes are
made by authorized personnel only.
In this cases, proceed as follows:
1.
Press the
button for more than 5 seconds; the upper
display shows
PASS
while the lower display shows
0
;
2.
By
and
button set the value
-181
;
3.
Push
button; the upper display shows the acronym
of the first parameter promoted to the level 2 and lower
display shows its value;
4.
Using
button it is possible to see the value assigned
to all parameters present in level 2 but will not possible to
modify them;
5.
It is possible to return to the “standard display” pushing
the
button for more than 3 seconds or by pushing no
buttons for more than 10 seconds.
7.4 Automatic Mode
7.4.1 Keyboard function when the instrument
is in Auto mode
Performs the action programmed by [121] uSrb
(
button function during RUN TIME) parameter.
Enters the parameter modification procedures.
a short pressure (less than 2 seconds) Displays the
“additional information” (see below)
a pressure longer than 2 second starts the “Direct Set
Point modification” function (see below).
Starts the “Direct Set Point modification” function (see
below).
+
Allows to enter in MANual mode and return to
AUTO mode.
Note:
To enter in MANual mode, press the
button
and (maintaining the pressure) within 1 s push the
button also; the MAN LED lights ON and the
lower display starts showing the power output.
To exit MANual mode, press the
button and
(maintaining the pressure) within 1 s push also the
button and maintain both pressed until the MAN
LED goes OFF.
7.4.2 Direct Set Point modification
This function allows to quickly modify the Set Point value select-
ed by [81] A.SP (selection of the active Set Point) or to the Set
Point of the segment (of the programmer) currently in progress.
While the instrument is showing the “Standard display”:
1.
Push the
or the
button for more than 2 s. The
upper display start showing the acronym of the selected
Set Point (e.g. SP2) while the lower one shows its value.
Note:
When the programmer is running, the instrument
shows the Set Point of the group currently in use
(e.g. if the instrument is performing the soak 3 the
instrument will show [107] Pr.S3).
2.
Using the
and
buttons, assign to this parameter
the desired value;
3.
Push no buttons 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 you to see the
value but not to modify it.
7.4.3 Additional information
The instrument is able to display some additional information
which can help in managing the system.
The additional information are related on how the instrument
is programmed, hence in many cases, only part of these
information are available.
1.
While the instrument is showing the “standard display”
push the
button for less than 2 seconds. The lower
display will show
H
or
c
followed by a 2 digit number.
This value is the output power (as a %) applied in that
moment to the process.
H
indicates that the instrument
is performing a Heating action while
c
means that is
performing a Cooling action.
2.
Push
again. If the programmer is running the lower
display shows the segment currently performed and the
Event status (see below): where the first character can be
r
for a ramp or
S
for a soak, the next digit indicates the
number of the segment (e.g.
S3
means Soak number 3)
and the two less significant digits (LSD) the status of the
two events (the LSD is the Event 2);
3.
Push
again. If the programmer is running the lower
display shows the theoretical remaining time to the end of
the program preceded by a
P
letter;
4.
Push
again. If the timer is running the lower display
s
and the remaining time to the end of the time count;
5.
Push
again. If the wattmeter function is running the
lower display shows
U
followed by the measured energy.
The energy calculation will be in accordance with the
[132] Co.tY parameter setting;
6.
Push
again. If the “Worked time count” is running the
lower display shows
d
for days or
h
for hours followed by
the measured elapsed time;
7.
Push
again. If
HBD
alarm has been programmed,
the lower display shows the
CT
measure during the ON
period preceded by the
C
letter;
8.
Push
again. If the
HBD
alarm has been programmed
the lower display shows the
CT
measure during the OFF
period preceded by the
o
letter;
9.
Push
again. If the
HBD
alarm has been programmed
the lower display shows the instantaneous current
measured by
CT
measure preceded by a
A
letter;
10.
Push
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.
