Warning system/alarm signals
• In the event of air flow obstructions
. If.the.air.flow.should.drop.below.the.preselected.
value.(175.or.225.l/min),.this.is.indicated.in.the.
following.way:
•.. A.pulsating.sound.signal.will.be.heard.
•.. The.red.warning.triangle.of.the.display.will.
flash.
Action: Immediately.interrupt.the.work,.leave.the.area,.
and.inspect.the.equipment.
• If the particle filters are clogged
. If.the.particle.filters.are.clogged,.this.is.indicated.in.
the.following.way:
•.. A.continuous.sound.signal.will.be.heard.for.five.
seconds.
•.. The.red.warning.triangle.in.the.display.will.
flash.
. The.warning.triangle.will.flash.continuously,.
whereas.the.sound.signal.will.be.repeated.at.
intervals.of.80.seconds.
Action:.Immediately.interrupt.the.work,.leave.the.area.
and.change.the.filter..
N.B..No.signal.is.activated.when.the.gas.filters.are.
saturated..For.particulars.of.changing.the.gas.filters,.
see.under.2.4.Filters.and.the.user.instructions.
supplied.with.the.filters.
• If the battery capacity is low
. If.the.battery.capacity.has.dropped.to.about.5.%.of.
the.original.charge,.this.is.indicated.as.follows:
•.. A.sound.signal.will.be.repeated.twice.at.
intervals.of.two.seconds.
•.. The.yellow.battery.symbol.of.the.display.will.
flash.
. The.battery.symbol.will.flash.continuously,.whereas.
the.sound.signal.is.repeated.at.intervals.of.30.
seconds.until.about.one.minute.remains.before.the.
battery.would.be.fully.discharged..The.sound.signal.
then.changes.to.an.intermittent.signal.
Action:.Immediately.interrupt.the.work,.leave.the.area.
