CALIBRATION LEVEL
All of the input and output types are calibrated in the factory. If a
recalibration is required, this should be carried out by a
experienced personnel. If this level is accidentally accessed, pass
through all the parameters without pressing the
or keys
pass
Password
Input of the Access Password.
This parameter is presented before the protected levels.
See item Protection of Configuration.
(alib
Calibration?
Enables or disables instrument calibration by the user,
YES: shows calibration parameters
No: Hides the calibration parameters

Input Low
Calibration
See section MAINTENANCE / Input Calibration.
Enter the value corresponding to the low scale signal
applied to the analog input.

Input High
Calibration
See section MAINTENANCE / Input Calibration.
Enter the value corresponding to the full scale signal
applied to the analog input.
Only showed if

rstr
Restore
Restores the factory calibration for all inputs and outputs,
disregarding modifications carried out by the user.
ovll
Output Low Limit
Lower limit for the control output - Minimum percentage
value assumed by the control output when in automatic
mode and in PID. Typically configured with 0 %. Default
value: 0 %
ovkl
Output High Limit
Upper limit for the control output - Maximum percentage for
the control output when in automatic mode and in PID.
Typically configured with 100 %. Default value: 100 %.

Cold Junction
Cold junction temperature controller.

Password
Change
Allows defining a new access password, always different
from zero.
Prot
Protection
Sets up the Level of Protection. See Table 04.
Freq
Frequency
Mains frequency. This parameter is important for proper
noise filtering.
snk
Shows the four first digits of the controller serial number.
snL
Shows the four last digits of the controller serial number.
CONFIGURATION PROTECTION
The controller provides means for protecting the parameters
configurations, not allowing modifications to the parameters values,
avoiding tampering or improper manipulation. The parameter
Protection (
PROt
), in the Calibration level, determines the
protection strategy, limiting the access to particular levels, as shown
by the Table 04.

ACCESS PASSWORD
The protected levels, when accessed, request the user to provide the
Access Password for granting permission to change the
configuration of the parameters on these levels.
The prompt
PASS
precedes the parameters on the protected levels.
If no password is entered, the parameters of the protected levels can
only be visualized.
The Access Password is defined by the user in the parameter
Password Change (
PAS.(
), present in the Calibration Level. The
factory default for the password code is 1111.
PROTECTION ACCESS PASSWORD
The protection system built into the controller blocks for 10 minutes
the access to protected parameters after 5 consecutive frustrated
attempts of guessing the correct password.
MASTER PASSWORD
The Master Password is intended for allowing the user to define a
new password in the event of it being forgotten. The Master
Password doesn’t grant access to all parameters, only to the
Password Change parameter (
PAS(
). After defining the new
password, the protected parameters may be accessed (and
modified) using this new password.
The master password is made up by the last three digits of the serial
number of the controller added to the number 9000.
As an example, for the equipment with serial number 07154321, the
master password is 9 3 2 1.
