Start up
Once the unit is installed change access passwords (see section 5.9).
Perform a load test before operating your gas detection system for the first time and after
each system component replacement – see section 8.4.
8.4
Load test
To perform a load test:
1. operate all outputs using the output test (see section 5.9),
2. observe the unit behaviour for a certain period (at least one minute),
3. check for any fault status on the display.
Test result can be assumed positive if:
devices connected to SO and SA outputs operate correctly,
no unit overload occurred during the test (see section 5.9).
If the test result is negative, remove the cause for system malfunction and repeat the test. See also
section 7.
If an overload occurs during unit operation (also during the load test), remove the cause of
load as soon as possible. Using the system with overload may result in its shut
down / damage in a critical situation (when there is a risk caused by a dangerous substance).

Periodical operations
It is recommended to perform interface test (see section 5.4) once a week.
It is recommended to perform output test (see section 5.9) once a month.
