Maintenance - Dräger PIR 3000 Instructions For Use Manual

Maintenance

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 re-
quired for gas entrance to the gas transmitter. Anything that blocks the gas en-
trance 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 / proc-
ess 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 trans-
mission, checking the alarm trigger and displaying the gas category" on page 13).
●
Check the calibration of the gas warning system (see "Calibration" on page 9).
Recommended calibration interval: 6 months.
Extending the maintenance intervals is possible if local conditions are taken into
account, and if the recommended maintenance intervals require cleaning, mainte-
nance 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 Safety to have them handle repairs and maintenance.
