c. Whenactuatorisinstalledandcoupled,ensurethatallmountinghardwareistightened
adequately,andsomemethodofthreadlockingisemployedonthemountin ghardware
(exceptforthecouplinghardware).

d. Ensureenvironmentalconditions(temperature,vibration, moisture,etc.)arenot
exceeded.

3. Ensurethatallwiringispertheappli
cablewiringdiagramandalsomeetsapplicablelocaland
nationalcodes.Particularatten
tionshouldbepaidtothefollowing:

e. Ifastep‐downcontroltransformeristhesourceof120VACpowerfortheLMV5,the
groundandneutralshouldbebonded(connected)onthetransformer.

f. Voltagesupplytoa120VACLMV5mustbebetween102and132VAC,47‐63Hz.
Waveformmu
stbeafullsinewave.

g. Thesmalltransformer(s)usedfortheLMV5(AGG5.210,typicallyblueorblack)mustbe
wiredandgrounded.SeeSection2(Wiring)formoredetails.Payattentiontopins3and
4onterminalSEK2andpropergrounding.IfmorethantwoSQM48andoneSQ
M45
actuatorsaremodulatedatthesametime,asecondtransformer(AGG5.210)willbe
required.

h. CANbuswire(AGG5.643)mustbeused towirebetweenactuators.Plain,shieldedcable
isnotadequateandisnotpermitted.

i. EnsurethatthelastdeviceandonlythelastdeviceontheCANbushasthetermination
jumperin
the“BusTermination”position.SeeSection2(Wiring)formoredetails.The
AZLhasbuilt‐intermination.

4. Fuel(gas)supply mustbeadequatetosupporthighfireoperationandfuel(gas)trainmustbe
sizedcorrectly.

j. Fuel(gas)pressurebeforethefiringratecontrolvalvemustbecorrect,stableand
repeatableatallfiringratesandmustnotvarywhenotherfuel(gas
)burningappliances
(otherboilersinthebuilding)arebeingoperated.

k. Thefu
el(gas)pressureregulatorontheburnerbeingcommissionedshouldnotbefully
openathighfireandsho
uldnotbebouncingofftheseatatlowfire.Fuelregulator
mustbesizedproperly,andhaveadequateturndowncapability.

5. AtemporarystackgasanalyzerthathasbeencalibratedandataminimumreadsO
2
(%)andCO
(ppm)mustbeusedforsettingcombustion.

6. Knowledgeofwhatfuelflowrepresentshighfireoftheburner/boilercombinationandalsothe
turndownoftheburner/boiler combination.Thiscantypicallybefoundontheburner/boiler
nameplate.
