Maintenance
Regular intervals
are to be determined for the following tasks by the persons responsible for the gas warning system while taking local
regulations into account:
Visual inspection to look for damage and contamination. Special attention is required for gas entrance to the gas transmitter.
Anything that blocks the gas entrance to the transmitter, e.g. dirt, ice, precipitation, etc., can prolong the response times or
even completely disable the gas transmitter. Recommended inspection interval: 3 months.
Visual inspection of the splash guard. If required, dismount gas exposure / process adapter and/or dirt deflector. Clean or
replace damaged splash guard.
Visual inspection of gas exposure / process adapter. Clean or replace damaged gas exposure / process adapter.
Visual inspection of the dirt deflector. Clean or replace damaged dirt deflector.
Check signal transmission and adjust if required (see "Checking the signal transmission, checking the alarm trigger and
displaying the gas category" on page 17).
Check the calibration of the gas warning system (see "Calibration" on page 11). Recommended calibration interval:
6 months.
Observe standard DIN EN 60079-29-2 (provided binding).
Extending the maintenance intervals is possible if local conditions are taken into account, and if the recommended
maintenance intervals require cleaning, maintenance or setup work. However, we do not recommend maintenance intervals
that are longer than 12 months.
Yearly
Inspection by competent personnel. The inspection intervals are to be individually determined with regard to safety
regulations, process control conditions and device-related requirements. We strongly recommend that a service contract be
signed with Dräger to have them handle repairs and maintenance.
