2 Switchgear diagnosis functions 2/16 Operating time Charging time Operating time Operation This function gives the value of the opening operating time of a breaking device (1) and change of status of the device open position contact connected to the I11 input (2) . The function is inhibited when the input is set for AC voltage (3) . The value is saved in the event of a power failure. Readout The measurement may be accessed via: b the display of a Sepam with advanced UMI by pressing the key b the display of a PC with the SFT2841 software b the communication link. (1) Refer to switchgear documentation for use of this information. (2) Optional MES module. (3) Optional MES114E or MES114F modules. Characteristics Measurement range 20 to 100 Unit ms Accuracy typically ±1 ms Display format 3 significant digits Charging time Operation This function gives the value of the breaking device (1) operating mechanism charging time, determined according to the device closed position status change contact and the end of charging contact connected to the Sepam I12 and I24 (2) . The value is saved in the event of a power failure. Readout The measurement may be accessed via: b the display of a Sepam with advanced UMI by pressing the key b the display of a PC with the SFT2841 software b the communication link. (1) Refer to switchgear documentation for use of this information. (2) Optional MES114 or MES114E or MES114F modules. Characteristics Measurement range 1 to 20 Unit s Accuracy ±0.5 sec Display format 3 significant digits PCRED301005EN - 06/2008
