If The On-butt is closed before, is cnected to voltage (also when line fault across On-Butt), the output ctacts will not close. A line fault across the On-butt which occurred after activati of the relay, will be detected with the next activati and the output ctacts will not close. ATTETIO! If a line fault occurs after the voltage has been cnected to,, the unit will be activated because this line fault is similar to the normal On-functi. The terminal permits the operati of the device in IT-systems with insulati mitoring, serves as a reference point for testing the ctrol voltage and is used to cnect the loop when cross fault mitoring is selected. Cnecting the terminal to the protective ground bridges the internal short-circuit protecti of Line (-). The short-circuit protecti of line () remains active. To alter the functis automatic start - manual start and with or without cross fault mitoring, the switches S1 and S2 are used. These are located behind the frt cover (see unit programming). The setting with or without cross fault mitoring butts is made with S1 (not for LG ). The LG has always cross fault mitoring. Attenti! Switch S1 must not be set while device is under supply voltage! S2 is used to change between automatic an manual restart. On automatic start also the terminals - have to be linked. For cnecti please see applicati examples. ATTETIO - AUTOMATIC START! According to IEC/E part and it is not allowed to restart automatically after emergency stop. Therefore the machine ctrol has to disable the automatic start after emergency stop en / 425
