Control and monitoring Logic inputs and outputs MT10680 MT10681 4 output relays on the base unit The 4 relay outputs O1, O2, O3 and O4 on the base unit are connected to connector A . Connector A of the base unit may be either of the following: b CCA620 screw-type connector b CCA622 ring lug connector. O1 and O2 are 2 control outputs used by the breaking device control function for: b O1: breaking device tripping b O2: inhibition of breaking device closing. O3 and O4 are indication outputs, only O4 can be activated by the watchdog function. CCA620 connector (screw-type terminal block for straight fittings). CCA622 connector (terminal block for ring lugs) MT10683 MES114 module (10 inputs / 4 outputs). Optional input/output modules The 4 outputs on the base unit may be completed by adding an MES114 10 input/ 4 output module on the back of the base unit. 3 modules are offered, MES114, MES114E or MES114F, to suit the different input voltage supply ranges. The modules offer different switching thresholds as well. The MES114 module is fully compatible with the MES108 (4 input/4 output) module which is no longer commercialized.

Control and monitoring Logic input / output assignment for Sepam series 20 Chart of logic input and output assignments for Sepam series 20 applications The use of the preset control and monitoring functions requires exclusive parameter setting and particular wiring of the inputs according to the application and type of Sepam. Input assignment and parameter setting of the control and monitoring functions may be done on the advanced UMI or using the SFT2841 software tool. Since a current input may only be assigned to a single function, not all the functions are available at the same time. Example: when the logic discimination function is used, the switching of groups of settings function may not be used.
