2.1 DESCRIPTION
The system consists of a control panel equipped with a display, keyboard and function keys.
This system enables temperature and humidity cycles to be carried out.
The system can operate Manually or Automatically.
2THE OP7 SYSTEM
The concept of HUMIDITY always
refers to Climatic Chambers. If the
chamber is not a climatic chamber,
you may ignore the relevant
references.

When a temperature grade is set (Centigrades per minute), it is unadvisable to set a humidity grade.
The two quantities interfere with each other and therefore the temperature grade would be observed,
whereas the humidity grade would not.
The humidity grade should, therefore, be set only when the temperature is kept constant.
Please refer to the MOLLIER diagram to establish the test logic to be carried out for both temperature
and humidity.

The programmes set on the OP7 panel have to be memorised permanently in the MICRO PLC; if there is a black-out or if
the machine is switched off, those programmes which have not been saved will be lost.
A specific guided procedure enables the relevant programmes to be both programmed and saved.
OP7 Technical Specifications:
N°10 memorisable programmes
N°99 segments for each programme
N°9999 programme repetitions
N°10 loops in each programme

2.3 BRIEF LIST OF THE MOST USED TERMINOLOGY
• Programme
Asetof instructions.Theprogramme canbememorisedinthemainmenu(MicroPLC)and then recalledin the work
memory (OP7) in order to be carried out. A programme that has just be set can be carried out even if it has not been
saved in the main menu. We advise you to always memorize your programmes in the main memory (MICRO PLC)
so as to avoid accidental deletions.
• Cycle: a set of several segments.
• Segment
Interval of time in which the required values that the chamber must carry out are set.
• Maintenance segment
A segment in which the set temperature (°C) and/or relative humidity (RH%) values are kept constant for a certain
period of time.
• Maximum speed segment
A segment which is carried out at the highest possible speed.
• Controlled slope segment
A segment in which the chamber must reach set point at the required speed (gradient).
• Gradient
Speed at which a segment is carried out. It is expressed as a ratio between the unit of measurement and the time
(C/min.; RH%/min. etc...).
• Set-point
The set value (temperature or relative humidity).
• Flag: Programme variables which may assume only two values or two different states (for example: 0 or 1; ON or
OFF; OK or OFF; SAVE or OFF; etc...)
• Repetitions
It enables an entire programme to be repeated automatically, starting from a specific segment. Up to 9999
repetitionsof the entire programme may be carried out. When the machine is switched on, the default value is 1 and
therefore the number of repetitions must always be reset. The operations included at this stage are not memorized
and therefore the data have to be reinserted each time you wish to repeat a programme.

6
• Loop table
This enables up to 10 repetitions of parts of a programme (series of segments or single segment) to be set. It is
possible to carry out another nested loop within a loop; the former, however, must be part of the main loop.
• Special and/or auxiliary contacts
To electrically switch on certain characteristic functions of the system as well as auxiliary contacts (external
apparatus).
• How to load a programme
Procedure to load a programme (already saved in the main memory) into the work memory (OP7). This procedure
is always carried out before executing a programme.
• How to save a programme
To memorize a programme permanently in the system’s main memory (Micro PLC).
• Channel 1
Temperature channel.
• Channel 2
Relative humidity channel.
• Duration wait
ON: the segment is considered finished only when the set time has passed. After this period of time the programme
moves on to the following segment, indipendently of the set temperature or humidity value.
OFF: the segment is considered finished when the set time finishes, whether the set point has been reached or not.
NB: The “Duration wait” and “Setpoint wait” flags must not both be turned OFF at the same time.
• Control System
ON: the relevant channel (temperature, humidity, etc..) is controlled
OFF: the relevant channel (temperature, humidity, etc...) is not controlled
• Wait set-point
ON: the segment is considered terminated only when the pre-set set-point value (temperature or relative humidity)
has been reached; the programme then moves on to the next segment.
OFF: the segment is considered terminated at the end of the pre-set time, whether the set-point has been reached
or not.
NB: The "Wait duration" and "Wait set-point" flags should never both be switched off at the same time.
• Maximum speed
ON: the set value (SET POINT) is reached at the highest possible speed.
OFF: the programme considers the set gradient.
• Near set
The tolerance within which the set point is considered to have been reached.
A default value is memorized; this value should not be changed.
In order for this indication to be effective while the programme is being carried out, the “Wait set-point” flag must be
switched on (ON).
• CTRL humid. spec.
ON/OFF: this option has been introduced in order to improve the performance of the system under certain work
conditions. On the basis of the results obtained during a cycle, the user may experiment by changing this flag to see
whether the chamber performance improves or not.
2.4 START-UP
• Use the main switch to turn on the machine.
If the START/STOP switch is not held down, the
following alarm message will appear:
• Press the START/STOP key.
• Use the ACK key to reset the alarm.

stopsand restarts either manuallyor automatically.
(This push butom may not be present according to
the version of the machine).
C)By switching off the main switch (isolating switch) The machine is switched off.
When it is switched on again:
- in MANUAL mode a cycle has to be reprogrammed and
restarted as the data will have been lost.
- inAUTOMATIC mode the cycle may be recalled and restarted.
The instructions to start up the cycles in
either MANUAL or AUTOMATIC mode
will be given in the following chapters.

2.5 HOWTOSETTHESOFTWAREALARMS
Never carry out a temperature cycle without having set the relevant software and hardware alarms.
Three alarm levels are usually available:
• Softwarealarms for maximum and minimumtempera-
ture (that can be set on the OP7 panel).
• Hardwarealarmsformaximumandminimumtempera-
ture (see chamber handbook).
• Fixed alarm for maximum temperature preset in the
factory (see chamber handbook).
How to set the software alarm for maximum and mini-
mum temperature
The alarms have to be defined after the minimum and
maximum value for the cycle that is to be carried out have
beendefined. If thealarms are not programmed and they set
off within the field of work, the cycle will be stopped and the
relevant alarm will be triggered.

(2) See the humidity range in the chapter entitled “Technical specifications”
Temperature values and other param-
eters are set on this page
In order to make the following instructions easier to understand, examples with the relevant values will be given.
Operations that can be carried out in manual mode:
3.2 HOW TO SET A CONTROLLED SLOPE
- Controlled temperature slope setting (Example 20 ÷35°C) with an
average gradient of 1°C per minute and 60% relative humidity.
- Humidity setting from 60 to 90% with a gradient of 2% per minute.
(in order to calculate the average gradient, that is the temperature rise or
descent speed, please refer to the technical data contained in the chamber
instruction handbook).
Steps to be carried out:
3.2.1 Step A: followthe sameproceduredescribed in paragraph3.1 so that
the departure temperature in the chamber reaches 20°C in manual mode.
3.2.2 Step B: set the final value to 35°C and follow a slope with a gradient
of 1°C/min. and 60% relative humidity.
The machine will reach the set temperature and humidity and will then
maintain these values;
3.2.3StepC: keepaconstanttemperature(35°C)andsetthecontrolledRH
humidity cycle (60÷90%) with a gradient of 2% per minute.
NB: if a mistaken gradient value is set, the machine will not follow the set
slope but will still reach the final temperature and humidity.
