Motorized Linear Actuator baelz 373-E45
5. COMMISSIONING
Comparethethrustoftheactuatorandthesettravelwiththevalvespecications.Overloading
canresultinseveredamagetothevalve.
Payattentiontomovingpartsduringttingandadjustment.Riskofinjuryandsubstantial
materialdamage.
Actuators which are supplied tted with a valve are set to the appropriate
valve stroke length. When an actuator with a 7020A digital positioner is
tted to a valve, an initialization run must be carried out to set up the
actuator according to the valve type.
Attention
5.1 Limit switch settings
Bydefault,theactuatorisswitchedoffintheendpositionsbythe"DE"switches(wiring
diagram,Fig.9,page21).Thesearefactory-settotheforceindicatedonthenameplate.
5.2 Test run
5.2.1 Checking the direction of rotation
● Adjusttheactuatormanuallytoroughlythemiddleposition.
● IndirectionoftravelCLOSE,switchtheactuatoronandwatchthedirectionofrotation.
● Ifthedirectionofrotationiswrong,switchoffimmediately.
● Checkwiring(jumpers).
● Repeatthetestrun.
If the direction of travel is set incorrectly, damage to actuator and valve is
imminent as the limit switches will not function with the wrong direction of
rotation!
Attention
5.2.2 Switching off in end positions
Risk of electric shock!
Danger
Iftheswitchesintheactuatorarenotfactory-wired,checkproperswitchingoffinendpositions:
With the cover removed, the linear actuator may only be operated briey for test runs or
when performing absolutely essential adjustments on electrical components, such as
potentiometer, limit switches or positioning electronics.
While performing this activity, there is unobstructed access to hazardous, live, exposed,
moving and rotating parts. Adjustments performed incorrectly or without exercising the
necessary caution may result in death, serious injury or substantial material damage.
Any operation of the linear actuator with the cover removed for a purpose other than
that described above is prohibited.
UseaninsulatedscrewdrivertoactuatetheswitchingrollersoftheDEswitchesasshownin
thewiringdiagram,Fig.9,page21,andcheckthattheeachswitchactuallyswitchesoffthe
motor.Ifnecessary,changethemotorsupplyjumpers.
