"ConF" –
Configuration parameters Menu: this contains all the
operating parameters and the functioning configuration parameters
(alarm configuration, control, input, etc.)
To enter the menu
“ConF”
select the option “ConF”, press the key
“P” and the display will show “0”.
At this request, enter, using keys “UP” and “DOWN”, the number
reported on the last page of this manual and push key “P”.
If an incorrect password is entered, the instrument exit from
programming mode.
If the password is correct, the display will visualise the code
identifying the first group of parameters (“
]
SP
“) and with keys “UP”
and “DOWN” it will be possible to select the desired group of
parameters.
Once the desired group of parameters has been selected, the code
identifying the first parameter of the selected group will be
visualised by pushing the “P” key.
Again using the “UP” and “DOWN” keys, it is possible to select the
desired parameter and, if the key “P” is pressed, the display will
show the parameter’s code and its programming value, which can
be modified by using the “UP” or “DOWN” keys.
Once the desired value has been programmed, push key “P” once
more: the new value will be memorised and the display will show
only the code of the selected parameter.
By using the “UP” or “DOWN” keys, it is then possible to select a
new parameter (if present) and modify it as described above.
To select another group of parameters, keep the “UP” or “DOWN”
key pressed for approx. 2 sec., afterwards the display will return to
visualise the code of the group of parameters.
Release the key and by using the “UP” and “DOWN” keys, it will be
possible to select a new group.
To exit the programming mode, no key should be pressed for
approx. 20 seconds, or keep the “UP” or “DOWN” pressed until exit
from the programming mode is obtained.
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 STATE
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, on the SV display, 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, visualised on the SV display, is the same as the last
one supplied and can be modified using the “UP” and “DOWN”
keys.
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).
In case of motorized actuators with time positioning, the manual
control of the output is obtainable in the following way :
- By pushing the UP key, the opening of the actuator is driven
- By pushing DOWN key, the closing of the actuator is driven
For all time during which the manual control is active, “3 Pt” or
“OPEn” is visible on the lower display if the UP key is pressed or
“CLOS” if the DOWN key is pressed.
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
- by digital input if par. “diF” = CHSP or = SP1.2 or =HECo)
- Automatically between SP1 and SP2 if a time “dur.t” (see par.
4.12) 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”.
