3.2 - Configuration

In order to access the configuration mode the operator is required to provide a
password which avoids a non-authorized person to change any critical parameters of the
process.
Thus, when press the ENTER key while the process variable is displayed within
the normal operating mode, the following cases may occur, depending on the
configuration:
i) Go straight at level 1 (GENERAL) of configuration mode, indicating that the
instrument has not been configured with a password system;
ii) On indicator display will show the warning PASS, indicating that the instrument
has a password system that can be a key or value, as shown in Figure 11.
Note: In the diagrams below, the rectangles represent
In the case of password key, the user must sequentially pressing the UP, DOWN
and ENTER key to enter the setting levels.
In the case of password with value the user must press for the second time the
ENTER key to display the number 00000 with the last zero flashing. The flashing digit
indicates the position where the user will enter a five-digit number password. To move to
the other digits of the left press the ENTER key. After entering all digits, press ENTER
again to move to level 1 if the password is correct, otherwise back to normal operation
(See Figure 11).
You can even select both password system, key and value. In this case, upon
receiving the password prompt the user to enter a sequence of incorrect keys he falls
immediately in the password system value.
When there are relays with trip alarms, the password system by keys will be
booked to reactivate the relays after a sensor break, while the password value is
permanently enabled to give access to the configuration levels.
The password can be a user-chosen number (custom) or the number 2030. Note
that for a password value the number 2030 is always enabled to help in case the user
forgets the password.
