Table 6 – All the Controller's Parameters

PROTECTION OF CONFIGURATION

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 below.

Only the Calibration level is protected.

and Calibration levels.

Table 7 – 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 cycles.
The prompt PASS precedes the parameters on the protected levels.

If no password is entered, the parameters of the protected cycles can

only be visualized.
The Access Code 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 of the access code
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.

PROGRAMS OF RAMP AND SOAK

This feature allows the creation of Ramp and Soak Setpoint Profiles

(Programs). Up to 20 different profiles with 9 segments each can

be programmed. Longer profiles of up to 180 segments can be

created by linking 2 or more profiles together.
The figure below displays a profile model:

Figure 8 - Example of a Ramp and Roak.

Once a profile is defined and selected for execution (parameter EPr

in the operating level), the controller starts to generate the SP profile

automatically in accordance with the elaborated program.
To execute a profile with fewer segments just program 0 (zero) for

the time intervals that follow the last segment to be executed.
