Timer Operation - Pentair 5600SXT Series Operator's Manual

TIMER OPERATION

Meter Immediate Control
A.meter.immediate.control.measures.water.usage.and.
regenerates.the.system.as.soon.as.the.calculated.system.
capacity.is.depleted..The.control.calculates.the.system.capacity.
by.dividing.the.unit.capacity.(typically.expressed.in.grains/unit.
volume).by.the.feedwater.hardness.and.subtracting.the.reserve..
Meter.Immediate.systems.generally.do.not.use.a.reserve.volume..
However,.in.twin.tank.systems.with.soft-water.regeneration,.
the.reserve.capacity.should.be.set.to.the.volume.of.water.used.
during.regeneration.to.prevent.hard.water.break-through..A.
Meter.Immediate.control.will.also.start.a.regeneration.cycle.at.
the.programmed.regeneration.time.if.a.number.of.days.equal.to.
the.regeneration.day.override.pass.before.water.usage.depletes.
the.calculated.system.capacity.
Meter Delayed Control
A.Meter.Delayed.Control.measures.water.usage.and.regenerates.
the.system.at.the.programmed.regeneration.time.after.the.
calculated.system.capacity.is.depleted..As.with.Meter.Immediate.
systems,.the.control.calculates.the.system.capacity.by.dividing.
the.unit.capacity.by.the.feedwater.hardness.and.subtracting.
the.reserve..The.reserve.should.be.set.to.insure.that.the.system.
delivers.treated.water.between.the.time.the.system.capacity.
is.depleted.and.the.actual.regeneration.time..A.Meter.Delayed.
control.will.also.start.a.regeneration.cycle.at.the.programmed.
regeneration.time.if.a.number.of.days.equal.to.the.regeneration.
day.override.pass.before.water.usage.depletes.the.calculated.
system.capacity.
Time Clock Delayed Control
A.Time.Clock.Delayed.Control.regenerates.the.system.on.a.timed.
interval..The.control.will.initiate.a.regeneration.cycle.at.the.
programmed.regeneration.time.when.the.number.of.days.since.
the.last.regeneration.equals.the.regeneration.day.override.value.
Day of the Week Control
This.control.regenerates.the.system.on.a.weekly.schedule..The.
schedule.is.defined.in.Master.Programming.by.setting.each.day.
to.either."off".or."on.".The.control.will.initiates.a.regeneration.
cycle.on.days.that.have.been.set.to."on".at.the.specified.
regeneration.time.
Control Operation During Regeneration
During.regeneration,.the.control.displays.a.special.regeneration.
display..In.this.display,.the.control.shows.the.current.
regeneration.step.number.the.valve.is.advancing.to,.or.has.
reached,.and.the.time.remaining.in.that.step..The.step.number.
that.displays.flashes.until.the.valve.completes.driving.to.this.
regeneration.step.position..Once.all.regeneration.steps.are.
complete.the.valve.returns.to.service.and.resumes.normal.
operation.
Pressing.the.Extra.Cycle.button.during.a.regeneration.cycle.
immediately.advances.the.valve.to.the.next.cycle.step.position.
and.resumes.normal.step.timing.
Control Operation During Programming
The.control.only.enters.the.Program.Mode.with.the.valve.in.
service..While.in.the.Program.Mode,.the.control.continues.
to.operate.normally.monitoring.water.usage.and.keeping.all.
displays.up.to.date..Control.programming.is.stored.in.memory.
permanently,.eliminating.the.need.for.battery.backup.power.
Manually Initiating a Regeneration
1.. When.timer.is.in.service,.press.the.Extra.Cycle.button.for.5.
seconds.on.the.main.screen.
2.. The.timer.advances.to.Regeneration.Cycle.Step.#1.
(backwash),.and.begins.programmed.time.count.down.
3.. Press.the.Extra.Cycle.button.once.to.advance.valve.to.
Regeneration.Cycle.Step.#2.(brine.draw.&.slow.rinse).
4.. Press.the.Extra.Cycle.button.once.to.advance.valve.to.
Regeneration.Cycle.Step.#3.(rapid.rinse).
5.. Press.the.Extra.Cycle.button.once.to.advance.valve.to.
Regeneration.Cycle.Step.#4.(brine.refill).
6.. Press.the.Extra.Cycle.button.once.more.to.advance.the.valve.
back.to.in.service.
NOTE:.. If.the.unit.is.a.filter.or.upflow,.the.cycle.step.order.
may.change.
NOTE:.. A.queued.regeneration.can.be.initiated.by.
pressing.the.Extra.Cycle.button..To.clear.a.queued.
regeneration,.press.the.Extra.Cycle.button.again.
to.cancel..If.regeneration.occurs.for.any.reason.
prior.to.the.delayed.regeneration.time,.the.manual.
regeneration.request.shall.be.cleared.
Control Operation During A Power Failure
The.SXT.includes.integral.power.backup..In.the.event.of.power.
failure,.the.control.shifts.into.a.power-saving.mode..The.control.
stops.monitoring.water.usage,.and.the.display.and.motor.shut.
down,.but.it.continues.to.keep.track.of.the.time.and.day.for.a.
minimum.of.48.hours.
The.system.configuration.settings.are.stored.in.a.non-volatile.
memory.and.are.stored.indefinitely.with.or.without.line.power..
The.Time.of.Day.flashes.when.there.has.been.a.power.failure..
Press.any.button.to.stop.the.Time.of.Day.from.flashing.
If.power.fails.while.the.unit.is.in.regeneration,.the.control.will.
save.the.current.valve.position.before.it.shuts.down..When.power.
is.restored,.the.control.will.resume.the.regeneration.cycle.from.
the.point.where.power.failed..If.power.fails.during.a.regeneration.
cycle,.the.valve.will.remain.in.it' s .current.position.until.power.
is.restored..The.valve.system.should.include.all.required.safety.
components.to.prevent.overflows.resulting.from.a.power.failure.
during.regeneration..
The.control.will.not.start.a.new.regeneration.cycle.without.
line.power..If.the.valve.misses.a.scheduled.regeneration.due.
to.a.power.failure,.it.will.queue.a.regeneration..Once.power.is.
restored,.the.control.will.initiate.a.regeneration.cycle.the.next.
time.that.the.Time.of.Day.equals.the.programmed.regeneration.
time..Typically,.this.means.that.the.valve.will.regenerate.one.
day.after.it.was.originally.scheduled..If.the.treated.water.output.
is.important.and.power.interruptions.are.expected,.the.system.
should.be.setup.with.a.sufficient.reserve.capacity.to.compensate.
for.regeneration.delays.
