FREQUENTLY ASKED QUESTIONS

 

WARNING

All  service  on  this  equipment  should  be  performed 

by Johnson Controls certified service personnel only. 

Death, severe personal injury, and/or equipment dam-

age may occur if service is not performed by competent 

personnel.

Why  don’t  the  measured  input  amps  shown  on  the 

Quantum

™

Lx control panel agree with the rated FLA?

The.input.current.to.the.Vyper

™

.may.be.considerably.lower.

compared.to.the.output.current..This.is.due.to.the.power.

factor.at.the.input.to.the.Vyper

™

.being.greater.than.0.95.

and.nearly.unity.when.the.harmonic.filter.option.is.included..

On the Remote-mounted Vyper

™

 compressor drive, what 

is the dV/dt “snubber” filter for?

The. combination. of. long. runs. of. wire. between. the. Frick.

 drive?

The.input.power.wires.are.sized.at.1.25.times.the.full.load.

amps.of.the.compressor.motor,.plus.oil.pump.amperage.and.

control.transformer.amps..

How is a 12-lead motor connected to the Vyper™?

Most.of.the.12.lead.motors.actually.have.two.sets.of.parallel.

windings,.and.therefore.have.two.ones,.two.twos,.etc..The.

Vyper

™

.is.connected.to.the.motor.in.the.delta.configuration,.

which.means.that.leads.are.paired.1.and.6,.2.and.4,.and.3.

and.5..The.T1.lug.in.the.Vyper

two.6s.attached.to.it.
Some.motors,.which.were.produced.in.the.past,.were.labeled.

as. 1. through. 12.. These. motors. had. the. first. set. of. wires.

marked.1.to.6..Numbering.then.continued.with.the.second.

second.set.of.numbers.above.six,.subtract.6.from.the.number.

and.relabel.the.result.

What is the peak input voltage value?

The.displayed.value.is.the.phase.to.neutral.voltage.at.the.

input.to.the.drive.in.terms.of.peak.voltage,.as.measured.by.

an.oscilloscope.
Phase. to. neutral. is. normally. the. phase-to-phase. voltage.

divided.by.the.square.root.of.three,.or.265.VAC.phase.to.

neutral,.for.a.460.VAC.system..The.peak.value.of.the.265.VAC.

measurement.is.approximately.that.number.times.the.square.

root.of.two.

When is a booster pump required on a Vyper™ compres-

sor drive?

The.Frick.Vyper

™

.requires.eight.(8).foot.of.head.for.proper.

coolant.flow.(water.or.glycol).to.the.heat.exchangers..If.this.

amount.of.head.is.not.available,.then.a.booster.pump.provid-

ing.at.least.10.or.15.foot.of.head.is.required.

The pink color of the coolant has faded. Is there a problem?

The.coolant.normally.has.a.pink.or.rosy.color.when.new..After.

months.of.operation,.this.color.may.dissipate,.and.the.coolant.

may.appear.almost.colorless..The.lack.of.color.in.the.cool-

ant.does.not.necessarily.indicate.a.problem..Most.colorless.

samples.test.above.1000.PPM.nitrite,.which.is.normal..There.

is.no.need.to.flush.the.system.unless.the.coolant.becomes.

opaque.or.cloudy..If.this.is.the.case,.please.obtain.a.sample.for.

analysis,.then.flush.the.system.with.coolant.and.install.fresh.

the.current.flowing.to.the.short.and.the.circuit.breaker.is.fast.

may.be.due.to.a.shorted.condition.inside.the.drive,.the.pres-

ence.of.a.ground.fault.condition,.or.due.to.the.breaker.itself.

•  If the VSD unit is running.
•  A  4-minute  timer  is  part  of  this  function  to  ensure 

that the DC Link Voltage is discharged to a safe level.
