The user can confirm the change in the normal status for the input for the external alarm by
pressing ENTER. The user can cancel the modification and return to the info menu by
pressing ESC.
5.4 Maintenance menu
The maintenance menu allows the user to configure the functions associated with the
maintenance-management alert, i.e.:
▪
the maintenance interval
▪
renewing the detector-calibration validity.
It is recommended that you maintain your installation on a yearly basis to guarantee
optimal monitoring. The user is therefore strongly discouraged from changing the value
of this interval.
The maintenance alert does not indicate a system malfunction but is merely a reminder.
However, renewing the detector-calibration validity may have a significant impact on the
gas-detection function and may cause the unit to not work properly if the detector is not
correctly calibrated any more.
5.4.1 Maintenance interval
Navigation :
Service menu
By default, the maintenance interval is set at 13 months.
It may be useful to adapt the maintenance interval under some conditions (specific
atmospheres, set or variable temperature and humidity conditions, etc.). It can be edited to
any interval ranging from 3 to 26 months.
Once the maintenance-interval modification has been selected, the current interval
configured in the U•H1 unit is displayed and the cursor flashes on the first digit of the value
in months.
The user can change the interval value using the Up and Down arrow keys.
The user can use the Right and Left arrow keys to move from one digit of the interval value
to the other, with the first digit changing the tens and the second digit changing the units.
The user can select the value chosen for the calibration interval using the ENTER key.
Confirmation is requested.
