Emotron MSF 2.0 Softstarter

Analogue inputThe analogue/digital input is used as an analogue input ifone of alternatives 6-7 in menu [500] is selected. In thiscase, the input can be configured for voltage or current signalusing jumper J1 (see Fig. 55). By default jumper J1 is setto voltage signal. According to the chosen alternative inmenu [500], the signal will be interpreted as 0-10 V/0-20 mA or 2-10 V/4-20 mA (see Fig. 56).15Analogue/digitalinputFig. 55 Wiring for analogue/digital input and setting of J1 foranalogue current or voltage control.[502] for a longer time than the analogue start/stop delaytime set in menu [504]. A stop will be performed if the referencesignal exceeds the analogue start/stop off-value chosenin menu [503] for a longer time than the analogue start/stop delay time set in menu [504].NOTE: If the selected analogue start/stop on-value isbigger than or equal to the off-value, a level above theon-value at the analogue input will cause a start. A valuebelow the off-value will in this case cause a stop.The start/stop LED on the front of the MSF will be flashingif the softstarter is in standby mode waiting for an analoguestart.WARNING: A flashing start/stop LED is indicatingstandby mode - e.g. waiting for an analogue start. Themotor may be started automatically at a moment'snoticeAnalogue start/stop on-value [502]This menu is available if analogue start/stop is activated inmenu [500] (alternative 6 or 7). If the reference signal onthe analogue/digital input is below the chosen on-level for alonger time than the analogue start/stop delay time chosenin menu [504], a start will be performed..NOTE: If the selected analogue start/stop on-value isbigger than or equal to the off-value, a level above theon-value at the analogue/digital input will cause a start.Fig. 56 Analogue inputAnalogue start/stopStarts and stops can be performed according to a process signalon the analogue/digital input. This means that e.g. theoperation of a pump may be controlled according to a flowsignal.Analogue start/stop is available if remote control or serialcommunication control is chosen in menu [200] (alternatives2 or 3).NOTE: Analogue start/stop is not available if controlpanel is chosen as control source in menu [200](alternative 1).InputsignalIf a start signal is given via remote or serial communication(according to the setting in menu [200]), the softstarter willcheck the reference signal on the analogue/digital signal. Astart will be performed if the level of the reference signal isbelow the analogue start/stop on-value chosen in menuNOTE: An analogue start will only be performed if thesoftstarter has been set to standby mode by a valid startsignal via remote control or serial communication.The analogue start/stop on-value is chosen as a percentage ofthe input signal range. This means, if the analogue/digitalinput is configured for 0-10 VDC/0-20 mA (alternative 6 inmenu [500]), 25% corresponds to 2.5 V or 5 mA. If theanalogue/digital input is configured for 2-10 VDC/4-20 mA(alternative 7 in menu [500]), 25% corresponds to 4 V or8 mA.5 0 225Analogue start/stop on-valueDefault: 25%Range: 0-100% of input signal range0-100 Analogue start/stop on-value.SettingEmotron AB 01-4135-01r2 Functional description 79
