The errormessage resetsautomatically.Device restartsautomatically withoutwarning.Faulty connection Isolate from supply,correct connection;see connectiondiagram.Broken motor winding Replace deviceThermal overloadprotector activatedAllow motor to cooloff, locate and rectifycause of error,release restart lockoutif necessaryDeficient cooling Improve cooling. Letthe device cool down.To reset the errormessage, switch offthe line voltage for atleast 25 s and thenswitch it on again.Alternatively, resetthe error message byapplying a controlsignal of < 0.5 V toDin1 or by shortingDin1 to GND.Ambient temperaturetoo highReduce the ambienttemperature. Let thedevice cool down.To reset the errormessage, switch offthe line voltage for atleast 25 s and thenswitch it on again.Alternatively, resetthe error message byapplying a controlsignal of < 0.5 V toDin1 or by shortingDin1 to GND.Impermissible point ofoperation (e.g. backpressure too high)Correct the operatingpoint.

The tripping currentis exceeded when AC testing voltage is applied.→ Test the device with DC voltage when you perform thelegally required high-voltage test. The voltage to be usedcorresponds to the peak value of the AC voltage required bythe standard.What to check How to check How often What action?Contactprotectioncover forintactness ordamageVisual inspection At least every6 monthsRepair orreplacement ofdeviceDevice fordamage toblades andhousingVisual inspection At least every6 monthsReplacement ofdeviceFastening thecablesVisual inspection At least every6 monthsFastenFastening theprotective earthterminalVisual inspection At least every6 monthsFastenInsulation ofcables fordamageVisual inspection At least every6 monthsReplace cablesTightness ofcable glandVisual inspection At least every6 monthsRetighten,replace ifdamagedCondensationdrainage holesfor clogging,where necessaryVisual inspection At least every6 monthsOpen holesWelds for crackformationVisual inspection At least every6 monthsReplace device6.3 DisposalFor ebm-papst, environmental protection and resource preservation aretop priority corporate goals.ebm-papst operates an environmental management system which iscertified in accordance with ISO 14001 and rigorously implementedaround the world on the basis of German standards.Right from the development stage, ecological design, technical safetyand health protection are fixed criteria.Item no. 50442-5-9970 · ENU · Change 89187 · Approved 2016-04-14 · Page 11 / 12ebm-papst Mulfingen GmbH & Co.
