Residual life
The control unit can display the residual operational lifetime of the sensor in weeks: this
figure is shown on the sensor setting screen as “TIME”. When the operational lifetime
descends to zero, the sign becomes negative and the system continues to operate and
count down the weeks of operational lifetime but of course there is no guarantee that the
sensor is operating correctly.
From the main menu, access “EXPIRED SENSOR LIST”; press
It will pull up the list of sensors that have exceeded the guaranteed lifetime.
If no sensor has expired the screen will show the following message:
On the other hand, if there are expired sensors, the display will show the following:

Displaying and changing the parameters of a field device
The operator can display the characteristics of a field device to find out more about the
operational status of the system. He can also change parameters such as threshold set-
points and operating status to adapt the system to suit his needs. It is also possible to
perform alarm simulation tests to verify the correct cabling of devices such as solenoid
valves, flashing lights etc.
Go to the main menu then continue as follows.
