width of the selected input type.
A(t
Action control:
re
Control with
Reverse Action
. Appropriate for
heating
. Turns control output on when PV is
below SP.

Control with
Direct Action
. Appropriate for
cooling
. Turns control output on when PV is
above SP.
0vt1
Operation mode of OUT1 and OUT2 outputs:
Off
Not used.
A1
Alarm output.
(trL
Control output.
0vt2
INPUT CYCLE
Type
Input type. Sets the input type used by the controller.

Dp.po
Decimal point. Sets the presentation mode of the
decimal point.
vn
i
t
Sets the temperature unit to be used:
(
Indication in Celsius.
f
Indication in Fahrenheit.
0ffs
Offset. Parameter that allows you to make corrections to
the indicated PV value.
Spll
SP Low/High Limit. Sets the lower/upper limits for
adjustments to the control SP value.
Does not limit the setting of the Alarm SP value.
Spxl
Fva1
Alarm functions. Sets the alarm functions from the
options in
Table 02
.
Sp.a1
Alarm SP. Sets the alarm actuation point. For
Differential
type functions, this parameter defines the
error (*).
Bla1
Blocking Alarm. This function blocks the alarms (*).
YES
Enables initial blocking.
NO
Inhibits initial blocking
.
Xya1
Alarm hysteresis. Sets the difference between the PV
value at which the alarm is turned on and the value at
which it is turned off (*).
Sp1.e
Allows to display
Sp.a1
parameter in the controller
Operation Cycle (*) (**).
YES
Displays
Sp.a1
parameter in the Operation
Cycle.
No
Does not display
Sp.a1
parameter in the
Operation Cycle.
(*) This parameter is not displayed when the alarm function is set to
off
or
ierr
.
(**) This parameter is not available for version 1.0x of the controller.
CALIBRATION CYCLE
All input types are calibrated at the factory. If a recalibration is
necessary, it must be performed by a specialized professional. If
this cycle is accessed accidentally, do not promote changes in
its parameters.
pass
Password. This parameter is shown before the
protected cycles. See
Configuration Protection
chapter.
(al
Calibration. Allows you to enable the function to
calibrate the controller. When the function is not
enabled, the calibration of the related parameters will
remain hidden.
inL(
Input Low Calibration. Allows you to enter the value
corresponding to the low scale signal applied to the
analog input.
ink(
Input High Calibration. Allows you to enter the value
corresponding to the full-scale signal applied to the
analog input.
rstr
Restore. Allows you to reset the input factory
calibrations, disregarding all changes made.
Pas.(
Password Change. Allows you to set a new access
password, always different from zero.
Prot
Protection. Allows you to define the protection cycle.
See
Table 03
.
CONFIGURATION PROTECTION
The controller allows you to protect its configuration, preventing
undue changes. In the Calibration cycle, the
Protection
parameter
(
PROt
) determines the protection cycle to be adopted, limiting
access to the cycles, as shown in the table below:
PROTECTION
CYCLE
PROTECTION CYCLE
1
Only Calibration cycle is protected.
2
Calibration and Input cycles are protected.
3
Calibration, Input, and Tuning cycles are
protected.
4
All cycles (including SP) are protected.
Table 3 –
Protection cycles
ACCESS PASSWORD
To access the Calibration cycle, a password is required. If entered
correctly, it allows changing the configuration of the parameters of
these cycles, including the
Protection
parameter (
PROt
).
You can set the password in the
Password Change
parameter
(
PAS.(
), which is also present in the Calibration cycle.
The
controllers leave the factory with the password set to 1111
.
PROTECTION ACCESS PASSWORD
The controller has a security system that helps prevent the entry of
numerous passwords to guess the correct password. Once 5
consecutive invalid passwords are identified, the controller stops
accepting passwords for 10 minutes.
MASTER PASSWORD
If you forget the password, you can use the Master Password
feature. When entered, this password gives access and allows
changing the
Password Change
parameter (
PAS(
). This makes it
possible to set a new password for the controller.
The master password is formed by the last three digits of the
controller serial number
plus
the number 9000.
Example: For a device with serial number 07154321, the master
password is 9321.
You can get the serial number of the controller by pressing
key
for 5 seconds.
