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 cycle 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

See section MAINTENANCE / Input Calibration.
Enter the value corresponding to the low scale signal

applied to the analog input.

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 %.

Password

Change

Allows defining a new access password, always different

from zero.

Prot

Protection

Sets up the Level of Protection. See Table 05.

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.

Table 04 – Levels of Protection for the Configuration

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.
