as specified by those responsible for the gas detection system (and which should
not exceed an interval of six months):

alarms (maintenance function SL – Set output to x mA, page 14).
Especially it must regularly be ensured that gas can freely penetrate the sinter disk

The inspection intervals in each individual case are influenced and if necessary shor-
tened by technical safety considerations, engineering processes and the technical
requirements of the equipment.
We recommend a DrägerService contract which also covers repairs.
