The programming and exit modes for the “OPEr” menu are the
same as those described for menu “ConF” with the difference that

to access the menù "OPEr" the Password is not required.

ATTENTION:

 The instrument is programmed in factory with all the

parameters, to exception of the Set Point "SP1" (and 2,3,4),
programmable in the menù "ConF" to the purpose to prevent wrong
accidental programming from non experienced consumers.

2.3 - PARAMETERS PROGRAMMING LEVELS

The menu “OPEr” normally contains the parameters used to

program the Set Point; however it is possible to make all desired
parameters appear or disappear on this level, by following this

procedure:
Enter the menu “ConF” and select the parameter to be made

programmable or not programmable in the menu  “OPEr”.
Once the parameter has been selected, if the LED SET is switched

off, this means that the parameter is programmable only in the
menu “ConF”, if instead the LED is on, this means that the

parameter is also programmable in the menu  “OPEr”.
To modify the visibility of the parameter, push key “U” : the LED

SET will change its state indicating the parameter accessibility level
(on = menu ”OPEr” and “ConF”; off = menu “ConF” only).

The active Set Point and the alarm thresholds will only be visible on
the Set Point fast programming level (described in par. 2.1) if the

relative parameters are programmed to be visible (i.e. if they are
present in the menu  “OPEr”).

The possible modification of these Sets, with the procedure
described in par. 2.1, is instead subordinate to what is programmed
in par. 

“Edit”

 (contained in the group “ 

]

PAn 

“).

This parameter can be programmed as :
=SE : The active Set Point can be modified while the alarm

thresholds cannot be modified.
=AE : The active Set Point cannot be modified while the alarm

thresholds can be modified
=SAE : Both the active Set Point and the alarm thresholds can be

modified
=SAnE : Both the active Set Point and the alarm thresholds cannot

be modified

2.4 - CONTROL  STATES

The controller can act in 3 different ways : automatic control

 (rEG),

  

control off 

(OFF)

 and manual control

 (OPLO).

The instrument is able to pass from one state to the other :
- by selecting the desired state from the main selection menu suing

the keyboard.
- By using the key “U” on the keyboard; suitably programming par.

“USrb” (“USrb” = tunE; “USrb” = OPLO; “USrb” = OFF) it is possible
to pass from “rEG” state to the state programmed on the parameter

and vice versa.
- Automatically (the instrument swaps into "rEG" state at the and of

the auto-tuning execution)
When switched on, the instrument automatically reassumes the

state it was in when it was last switched off.

AUTOMATIC CONTROL (rEG)

 – Automatic control is the normal

functioning state of the controller.

During automatic control it is possible to visualize the control power
on the display by pushing key “UP”.

The range of the power values goes from H100 (100% of the output
power with reverse action) to C100 (100% of the output power with

direct action).

CONTROL OFF (OFF)

 – The instrument can be swapped into the

“OFF” state, i.e. the control and the relative outputs are
deactivated.

The alarm outputs are instead working normally.

BUMPLESS MANUAL CONTROL (OPLO)

 – By means of this

option it is possible to manually program the power percentage

given as output by the controller by deactivating automatic control.
When the instrument is swapped to manual control, the power

percentage is the same as the last one supplied and can be
modified using the “UP” and “DOWN” keys.

As in the case of automatic control, the programmable values
range from H100 (+100%) to C100 (-100%).

To return to automatic control, select  "rEG" in the selection menu.

2.5 - ACTIVE SET POINT SELECTION

This instrument permits pre-programming of up to 4 different Set
points (

“SP1”

“SP2”

“SP3”

“SP4”

) and then selection of which

one must be active. The maximum number of Set points is
determined by the par. 

"nSP"

 located in the group of parameters “

]

SP 

“. 

The active Set point can be selected :
- by parameter 

"SPAt"

 in the group of parameters “ 

]

SP 

“.

- by key “U” if  par. "USrb" = CHSP

- Automatically between SP1 and SP2 if a time “dur.t” (see par. 4.8)
has been programmed.

Set Points “SP1”, “SP2”, “SP3”, “SP4” will be visible depending on
the maximum number of Set Points selected on par. “nSP” and they

can be programmed with a value that is between the value
programmed on par.  

“SPLL”

 and the one programmed on par.

“SPHL”.

 

Note

 : in all the following examples the Set point is indicated as

"SP", however the instrument will act according to the Set point
selected as active.

3 - INFORMATION ON INSTALLATION AND USE

3.1 - PERMITTED USE

The instrument has been projected and

manufactured as a measuring and control device to
be used according to EN61010-1 for the altitudes

operation until 2000 ms.The use of the instrument
for applications not expressly permitted by the

above mentioned rule must adopt all the necessary protective
measures. The instrument CANNOT be used in dangerous

environments (flammable or explosive) without adequate
protection. The installer must ensure that EMC rules are respected,

also after the instrument installation, if necessary using proper
filters.

 

Whenever a failure or a malfunction of the device may cause

dangerous situations for persons, thing or animals, please
remember that the plant has to be equipped with additional devices

which will guarantee safety.

3.2 - MECHANICAL MOUNTING

The instrument, in case 33 x 75 mm, is designed for flush-in panel

mounting. Make a hole 29 x 71 mm and insert the instrument, fixing
it with the provided special bracket. We recommend that the gasket

is mounted in order to obtain the front protection degree as
declared. Avoid placing the instrument in environments with very

high humidity levels or dirt that may create condensation or
introduction of conductive substances into the instrument. Ensure

adequate ventilation to the instrument and avoid installation in
containers that house devices which may overheat or which may

cause the instrument to function at a higher temperature than the
one permitted and declared. Connect the instrument as far away as

possible from sources of electromagnetic disturbances such as
motors, power relays, relays, solenoid valves, etc.

3.3 - ELECTRICAL CONNECTION

Carry out the electrical wiring by connecting only one wire to each

terminal, according to the following diagram, checking that the
power supply is the same as that indicated on the instrument and

that the load current absorption is no higher than the maximum
electricity current permitted. As the instrument is built-in equipment
