Integrated operating elements
• Door UP
.
Pressing.the.UP.button.(front).opens.the.door.in.self-locking..The.door.stops.automatically.when.the.upper.end.limit.is.
reached.or.if.a.safety.function.actuates.(e.g..emergency.stop.switch).
.
If.you.wish.to.change.to.the.Up.direction.while.the.door.is.descending,.you.must.press.the.Stop.button.first.of.all.
• STOP
.
The.opening.or.closing.door.can.be.stopped.immediately.in.any.position.by.pressing.the.STOP.button.(front).
• Door DOWN
.
Pressing.the.DOWN.button.(front).closes.the.door.in.deadman’s.mode..If.the.“Multicard.II”.is.used.with.safety.edge.and.
light.barrier,.closing.occurs.in.self-locking..The.door.stops.automatically.when.the.lower.end.limit.is.reached.or.if.a.safety.
function.actuates..If.the.bottom.pneumatic.safety-edge.rail.or.light.barrier.actuates,.the.door.stops.and.then.moves.to.the.
upper.final.position.or.clears.the.obstacle,.depending.on.the.setting.of.the.Multicard.II.
• Emergency stop switch (optional)
.
When.the.emergency.stop.switch.is.activated,.the.control.voltage.is.switched.off..The.“+UB”.LED.on.the.motherboard.goes.
out.and.the.drive.is.switched.off.immediately..Further.door.movement.is.only.possible.after.releasing.the.emergency.stop.
switch.
Control inputs and external pick-ups
Note
See also “Functional overview”.
• External pick-ups (UP STOP DOWN)
.
An.additional.triple.pushbutton.can.be.connected,.which.is.identical.in.function.to.the.buttons.on.the.front.of.the.control.
• EMERGENCY STOP switch (EMERGENCY STOP)
.
The.S50II.control.can.be.supplied.with.an.EMERGENCY.STOP.switch.in.the.housing.cover,.if.required.
• Slack cable limit switch (EMERGENCY STOP)
.
A.slack.cable.limit.switch.can.be.connected.in.series.with.the.EMERGENCY.STOP.switch.
• Bottom pneumatic safety-edge rail (USA)
.
An.electrical.(EL).or.pneumatic.(DW).safety.contact.rail.with.1.2kOhm.or.8.2.kOhm.can.be.connected.
• Pulsed input (IMP)
.
For.example,.a.ceiling.pull.switch.can.be.connected,.which.converts.the.commands.into.the.step.switching.sequence.UP-
STOP-DOWN-STOP-UP......
• Light barrier (LS)
.
If.the.light.barrier.is.interrupted.(break.contact),.the.door.stops.and.ascends.again..In.conjunction.with.the.automatic.re-
closing.function,.the.light.barrier.resets.the.closing.time.to..seconds.
• Automatic reclosing feature (WZL)
.
If.the.automatic.reclosing.feature.is.activated,.the.open.door.closes.automatically.after.a.preset.time.
The.Multicard.II.insert.card.also.provides.the.following.connection.options:
• Partial opening
• Optical safety device OSE (FRABA)
.
For.the.exact.functions.and.settings,.please.refer.to.the.instructions.for.the.relevant.insert.card.
Potential-free relay
A.relay.with.potential-free.change-over.contact.is.located.on.the.motherboard.of.the.S50 II.(terminals.C,.NC,NO)..Using.func-
tion.switch.FS1,.you.can.select.whether.the.relay.is.actuated.via.the.Multicard.II.insert.card.or.via.the.S8.limit.switch.of.the.
drive.
In.position.FS1=A.the.relay.is.actuated.by.the.control.card.
In.position.FS1=B.the.relay.is.actuated.by.limit.switch.S8.(green.cam).
