3.2 Model ST100X
The.rated.operating.voltage.is.230V.
The.control.push-button.panel.is.integrated.in.to.the.
controller.
The.control.electronics.are.situated.under.the.control.
push-button. panel. and. enclosed. in. a. plastic. housing.
To. simplify. installation. and. facilitate. the. reading. of.
the. push-button. panel,. it. is. also. possible. to. install.
the.controller.on.a.workbench.or.mount.it.on.the.wall.
by.simply.rotating.the.control.panel.
The. plastic. material. of. the. housing. ensures. a. high.
level.of.insulation.and.the.utmost.safety.during.use.
The.rear.part.of.the.controller.has.a.block.with.a.male.
pin.(designed.to.be.connected.to.the.power.cable),.
an.ON–OFF.(0-1).switch.and.a.fuse-holder.with.two.
12.5A.protection.fuses.(type.5x20.mm)..Two.or.more.
cable.ties.for.the.output.of.the.discharge.cables.of.
the.chucks.to.be.magnetized.may.be.present.next.to.
these.components.
The. maximum. useful. current. that. flows. into. the.
ST100X. controller. is. approximately. 12.5A;. the. current.supplied.to.the.module.is.impulsive.with.a.cycle.

The.rated.operating.voltage.of.this.controller.varies.
according.to.the.type.of.magnetic.chuck.to.which.it.
is.connected.
The.control.push-button.is.external,.but.can.also.be.
integrated.into.the.controller.
The.control.electronics.are.enclosed.in.a.metal.housing..The.metal.material.of.the.housing.is.grounded.in.
order.to.guarantee.maximum.safety.during.the.enabling.cycles.
It.is.important.to.verify.that.the.grounding.system.is.
always.in.good.working.order.
The.controller.does.not.have.a.socket.for.the.connection.to.the.power.supply..The.controller.has.an.
ON–OFF.(0-1).switch,.thus.to.adequately.protect.it.
against.short.circuits,.it.is.necessary.to.install.a.suitable.protection.system.upstream.from.the.controller..
It. is. generally. advisable. to. use. a. magneto. thermal.
switch.(curve.C).with.an.I
n
.value.compliant.with.the.
rating. specified. on. the. magnetic. chuck. nameplate.
that.will.be.connected.to.the.controller.
The. maximum. power. of. controller. ST200X. is. approximately.25kW.per.discharge.if.the.single.phase.
power.supply.is.400V,.15kW.for.power.supplies.of.
230V.and.30kW.for.power.supplies.of.480V..The.absorbed.current.is.impulsive.with.a.cycle.time.around.
a. few. hundreds. of. milliseconds. (approximately. 1.
second.per.discharge).
ST200X. controllers. are. suitable. to. power. single.
chucks. or. chucks. that. are. part. of. large. magnetic.
banks
When. using. chucks. with. a. different. rated. voltage,.
install. a. transformer. with. a. suitable. transformation.
ratio.and.a.rated.power.that.matches.the.maximum.
power.of.the.chuck.
It. is. also. possible. to. order. a. compact. version. for.
ST200-QE.electric.cabinets.with.supporting.terminal.
board,.to.power.the.controller.and.magnetic.chuck,.

INSTALLATION
Check.the.supply.voltage.and.frequency.
The.electrical.supply.to.the.controller.must.be.single-phase.230V/400V/480V.(phase.+.neutral).or.twophase.(phase.+.phase)..
4.1 General
Electric.safety.can.be.guaranteed.only.if.the.electric.
system. is. correctly. connected. to. a. grounding. system.in.good.working.order,.as.foreseen.by.current.
laws. concerning. electric. safety.. Therefore,. it. is. essential.to.always.verify.this.safety.requirements.before.starting.the.unit.and.have.the.distribution.system. carefully. inspected. by. qualified. personnel. in.
case.of.doubt..TECNOMAGNETE.S.p.A..shall.not.be.
responsible.for.damages.originating.from.the.failure.
to.connect.the.unit.to.an.appropriate.grounding.system.
Users.shall.have.to.make.sure.that.the.unit.is.protected. with. a. differential. magnetothermal. switch.
suitable.to.withstand.the.rated.current.used.by.the.
system..It.is.therefore.necessary.to.install.a.suitable.
protection. with. magnetothermal. switch. (curve. C).
with.a.I
n
.value.compliant.with.nameplate.data.
TECNOMAGNETE. systems. are. permanent-electro.
systems,.which.means.that.they.need.to.be.powered.
only.during.the.short.cycle.phases..This.configuration. is. designed. to. ensure. maximum. safety. in. the.
event.of.power.failure.
TECNOMAGNETE.controllers.use.the.power.supply.
by. means. of. a. sophisticated. partializing. process,.
which.means.that.they.can.be.operated.only.when.
the.machine.is.idle.and.that.they.require.a.rated.current.that.is.normally.lower.than.the.one.required.to.
operate.the.machine.on.which.the.magnetic.system.
being.controlled.is.installed.
ATTENTION
ST100.controllers.are.designed.to.operate.with.supply.voltages.of.230V.50/60.Hz.and.cannot.therefore.
be. used. for. Tecnomagnete. modules. with. lower. or.
higher. ratings.. To. use. different. voltages,. install. a.
transformer.with.a.suitable.rating.(not.above.4.kVA).
or.contact.TECNOMAGNETE.S.p.A..for.assistance.
ATTENTION
ST200. controllers. are. designed. to. operate. with.
supply. voltages. of. 200V. -. 480V. at. 50/60. Hz. and.
can. therefore. be. used,. after. validation,. to. enable.
TECNOMAGNETE. modules. with. different. voltage.
specifications.. To. use. different. voltages,. install. a.
transformer. with. a. rating. compliant. to. that. of. the.
magnetic.chuck.or.contact.TECNOMAGNETE.S.p.A..
for.assistance.
ATTENTION
All.cables.supplied.must.have.a.bending.radius.with.
a.diameter.<10mm.and.a.tension.of.>15N/mm 2 ..Installation. must. always. be. performed. by. qualified.
technicians.in.accordance.with.current.law.requirements.
ATTENTION
Do not perform repeated MAGNETIZATION/DE-
MAGNETIZATION CYCLES
TECNOMAGNETE. systems. are. constituted. by. permanent.magnets.and.use.electric.power.only.to.enable/disable. the. area. being. machined.. Therefore,.
they. can. be. regarded. “COLD”. magnetic. clamping.
systems.
The. repetition. of. MAGNETIZATION/DEMAGNETI-
ZAZION.cycles.at.very.close.intervals.may.increase.
the. temperature. of. the. magnetic. chuck,. especially.
when.using.controllers.with.DEMAG.NUFLUX.cycle.
It.is.therefore.advisable.to.run.cycles.only.when.necessary.
The.connection.of.the.magnetic.chuck.to.the.power.
supply. must. be. carried. out. by. qualified. personnel.
only.

ANALYSIS OF RESIDUAL
RISKS
11
MAINTENANCE
11.1 Premise
..
In designing the chuck, the manufacturer has taken into account specific manufacturing criteria and all applicable and current safety requirements, which do not however eliminate other potential residual risks.
This chapter provides a description of the potential risks that could arise in specific situations.
• As the controller is designed to be used to control TECNOMAGNETE modules that are generally installed on tool machines, it is essential to make sure that operators have read and are familiar with the instructions provided in this manual, in the manual of the module and of the tool machine on which the module is installed. Operators must also be made aware of any other potential residual risk.
• The individual protection means that have to be used when working with the chuck are the same ones required for the use of the tool machine on which the module is installed.
• As for the potential residual risks originating from the exposure to electromagnetic fields, specific precautions should be taken by pregnant women; users suffering from specific pathologies; users with pacemakers or other prosthesis with electronic circuits including hearing aids, intracranial metal implants (or any other implant situated next to vital anatomic structures), vascular clips or chips in ferromagnetic material. It is useful to remember that:
1. TECNOMAGNETE magnetic systems are stationary systems and do not generate electric fields.
2. The V/m (Volt/meter) value generated during operation is equivalent to 0 (ZERO).
3. The electromagnetic emissions generated during the enabling/disabling phase does not exceed 100 Gauss at a distance of 100 mm from the system.
