than the initial scale read-out in order to obtain a
reverse read-out scaling. For example:
0 mA = 0 mBar and 20 mA = -1000 mBar (vacuum).
[5] unit - Engineering unit
Available: When a temperature sensor is selected by
[1] SenS parameter.
Range: °c Centigrade;
°F Fahrenheit.
m
The instrument does not rescale the temperature
values inserted by the user (thresholds, limits etc.).
[6] FiL - Digital filter on the measured value
Available: Always.
Range: oFF (No filter)
0.1... 20.0 s.
Note: This is a first order digital filter applied on the measured
value. For this reason it will affect the measured value
but also the control action and the alarms behaviour.
[7] inE -
Selection of the Sensor Out of Range type
that will enable the safety output value
Available: Always.
Range: our When an overrange or an underrange is de-
tected, the power output will be forced to the
value of [8] oPE parameter.
or
When an overrange is detected, the power output
will be forced to the value of [8] oPE parameter.
ur
When an underrange is detected, the power output
will be forced to the value of [8] oPE parameter.
[8] oPE - Safety output value
Available: Always.
Range: OFF;
-100... 100% of the output.
Notes: 1. When the instrument is programmed with one
control action only (heat or cool), setting a value
outside of the available output range, the instrument
uses Zero. For example:
When heat action only has been programmed, and
oPE is equal to -50% (cooling) the instrument uses 0.
2. When ON/OFF control is programmed and an out
of range is detected, the instrument performs the
safety output value using a fixed cycle time equal
to 20 seconds.
3. When the control output is a Open Loop valve
control, a value equal or lower than zero switches
ON the “close” output (OUT 2) while a positive
value switches ON the “open” output (Out 1).
4. When OFF is selected the instrument operates
as follows: when a burnout condition is detected
the instrument goes automatically in MAN mode.
Removed the burnout condition, the instrument
remains in MAN mode until Auto mode is selected
(by OPEr parameter, a command by serial link,
digital imput or by the key pressure).
[9] diF1 - Digital input 1 function
Available: Always.
Range: oFF No function;
1 Alarm Reset [status];
2 Alarm acknowledge (ACK) [status];
3 Hold of the measured value [status];
4 Stand by mode of the instrument [status].
When the contact is closed the instrument
operates in stand by mode;
5 Manual mode;
6 HEAt with SP1 and CooL with “SP2” [status]
(see “Note about digital inputs”);
7 SP1/SP2 selection [status];
[10] diF2 - Digital input 2 function
Available: When [9] Io4.F = diG2.
Range: oFF No function;
1 Alarm Reset [status];
2 Alarm acknowledge (ACK) [status];
3 Hold of the measured value [status];
4 Stand by mode of the instrument [status].
When the contact is closed the instrument
operates in stand by mode;
5 Manual mode;
6 HEAt with SP1 and CooL with “SP2” [status]
(see “Note about digital inputs”);
7 SP1/SP2 selection [status];
Note about digital inputs:
When [10] diF1 or [11] diF2 (e.g. diF1) is equal to 6
the instrument operates as follows:
• When the contact is open, the control action is an heat-
ing action and the active set point is SP.
• When the contact is closed, the control action
is a
cooling action and the active set point is SP2.
[11] di.A - Digital Inputs Action
Available: DI1 always, DI2 when present.
Range: 0 DI1 Direct action, DI2 Direct action;
1 DI1 Reverse action, DI2 Direct action;
2 DI1 Direct action, DI2 Reverse action;
3 DI1 Reverse action, DI2 Reverse action.
]out Group - Output parameters
[12] O1.t - tOut 1 type
Available: When the out1 is a linear output (hardware).
Range: 0-20 0... 20 mA;
4-20 4... 20 mA;
0-10 0... 10 V;
2-10 2... 10 V.
Note: When Out 1 is linear, the Out1 LED will be OFF when
the output is equal to zero and ON when the power
output is different from zero.
[13] o1F - Output 1 function
Available: Always
Range: nonE Output not used;
H.rEG Heating output (reverse);
c.rEG Cooling output (direct).
m
When using the servomotor control, both Out1
and
Out2 are to be selected as Heating or Cooling
(o2F = o3F = HrEG or o2F = o3F = crEG);
Parameter [39] cont must be set as 3pt.
