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.

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.
