Emotron MSF 2.0 Softstarter

Example1. If only one running direction is used, digital input 1 canbe configured for start signal and digital input 2 for stopsignal (default setting). In this case relay K1 may be configuredfor operation (default setting) and can controlthe mains relay. When digital inputs 1 and 2 are closedto their respective supply terminals, the mains contactorwill be activated and the motor will start. When digitalinput 2 is opened the motor will stop. The mains contactorwill be deactivated after the stop has been finished.2. If two running directions are desired, digital input 1 canbe configured for start R, digital input 2 for stop anddigital input 3 for start L. Relay K1 controls the mainscontactor for running in right direction and may be configuredfor Operation R. Relay K2 controls the mainscontactor with the opposite phase sequence for runningin left direction and may be configured for Operation L.In this case closing digital inputs 1 and 2 to their respectivesupply terminals (start right command) will lead toactivation of the mains contactor for running in rightdirection and the motor will start in right direction.Opening digital input 2 will lead to a stop; the mainscontactor for running right will be deactivated after thestop has been finished. Closing digital inputs 2 and 3 totheir respective supply terminals (while digital input 1 isopen) will lead to activation of the mains contactor forrunning in left direction and the motor will start in leftdirection.For more information see the description of the start right/left functionality in section 8.9.4, page 87.External alarmThe digital inputs can be configured as external alarminputs. If an input configured for external alarm is opened,the action chosen in menu [420] for external alarm is performed.See description of the external alarm functionalityin section 8.9.5, page 91 for more information.NOTE: If more than one digital input is configured forexternal alarm, opening any of these will lead to anexternal alarm.Parameter setThis configuration enables choice of parameter set by anexternal signal.
