* When operating together with the “Z-Modul-B” type add-on module, the diagnosis menu is automati-cally expanded to include the additional inputs and outputs (installation not possible in Icontrol flat).11.1 Special features for measurements at the innverter and motor11.1.1 Measuring arrangementPulse-width-modulated voltages can cause malfunctions and measurement errors by capacitiveunbalances.Such types of errors can be avoided, or at least be considerably reduced, if a number ofbasic rules are observed:1. Spatial separation of control cables from motor current and lines cables.2. Spatial separation of line and motor cables.3. Screening of the control cables.4. Screening of the motor cables.5. Use only screening measuring cables with the probe. Do not configure these parallel to motorcables11.1.2 Voltage measurementsVoltage measurements can be made without restrictions only on the the mains side of the frequencyinverter or EC controller.Due to the content of the harmonic frequencies, on the motor side meaningful measurements are onlypossible when using measuring equipment that is capable of measuring the fundamental voltage.11.1.3 Current measurementsCurrent measurements can be made without restrictions only on the motor side of the frequencyinverter or EC controller.Line side measurements of the current may only be performed using true r.m.s. measuring equipment.The line current cannot be measured with sufficient accuracy using customary measuring equipment(for sinusoidal currents of corrected arithmetic mean).12 Events / Fault signals12.1 Display and query of events and malfunctionsEventsEvents during operation can lead to a malfunctioning of the device.The last 10 (0 - 9) events and malfunctions are stored in the “Events” menu group(position “0” = most recent event).Essemple for possibleeventsThe device differentiates between 3 types of events:Sensor 11. Messages with code |Msg|Message sensor fault for information, for Alarm sensordeactivated.External error2. Alarms with code |AL| Events during which the device automatically restartsoperation after the cause of the malfunction has been remedied (e.g. mains failure), orremains in operation (e.g. externally-trunked centralized fault).Motor fault3. Error with code |Err| Events that lead to a disconnection of the controlled output(e.g. excess motor temperature). Restarting is only possible after a reset (locked).Motor faultControllers period of operation at time of message:With the P key can be switched between description of themessage and the Controllers period of operation at this time.E.G. on place 3 which is past message motor fault. 00009:01:08Operating Instructions Icontrol – model series FXDM Events / Fault signalsL-BAL-E036-GB 1422 Index 008 Part.-No. 00154773-GB83/96 |
