Ex. No. 1.4 Safe standstill for non-interlocked protective doors, implemented with one safety combination “Safe standstill“ with MASTERDRIVES for a non-interlocked protective door with safety combination, stop Category 1, Category 3 acc. to EN 954-1 402 Functional Example No. MC-FE-I-001-V11-EN
Function description A structure in compliance with EN 954-1 control Category 3 and EN1037 can be implemented using one SIGUARD safety combination for the protective doors. The drive is shut down (stopped) according to stop function Category 1 according to EN 60204-1. ■ <strong>Safety</strong> combination for protective door monitoring functions corresponds to Category 4 (instantaneous enable circuit) or Category 3 (delayed enable circuit). ■ Circuit for protective door monitoring is monitored through 2 channels in a cross-circuit proof fashion. Behavior when the protective doors are opened When the protective doors are opened, it is initiated that the drive is shut down according to stop Category 1 in compliance with EN 60204-1. It must be ensured that potentially hazardous motion must have come to a standstill before a person can reach the potentially hazardous area! ■ A 0 signal is entered, via the enable contact of safety combination A1, at contact X101.X (OFF3) of the drive. The drive is immediately braked down to 0 speed and the pulses are cancelled. The delay time of safety combination A1 is simultaneously started and the drive must have come to a standstill before it expires. Powering-up and powering-down the drive The drive can be started or stopped when the protective doors are closed. ■ When the internal safety relay and line contactor K1 are in the correct state, safety combination A1 is brought into an operational state. ■ Line contactor K1 and the internal safety relay of the drive are energized. ■ When pressing S2 ("On"), contactor K2 is energized and latches. A 1 signal is entered at contact X101.X (OFF3) of the drive and the drive starts. ■ Switches S4 and S5 are positively opening position switches corresponding to EN 1088. ■ The drive is shut down via the internal safety relay and the higher-level line contactor K1. ■ On circuit of safety combination A1 monitors whether the line contactor K1, the internal safety relay of the drive, as well as contactor K2, have dropped-out after the protective doors have been opened. (This is necessary in the sense of control Category 3 in compliance with EN 954-1!). ■ The safely delayed enable contacts of safety combination A1 open after the selected delay time has expired. This means that the internal safety relay of the drive (1st shutdown path!) and line contactor K1 (2nd shutdown path!) are no longer energized. ■ If the internal safety relay functions incorrectly or if line contactor K1 has not dropped-out, then its checkback signal contacts X533.1/2 in the on circuit of the safety combination A1 are not closed. The safety combination cannot be switched-in. ■ When button S1 ("Off") is pressed, contactor K2 is no longer energized and a 0 signal is entered at contact X101.X (OFF3) of the drive. The drive is immediately braked down to 0 speed and the pulses are cancelled. If the protective doors are opened, the safely delayed enable contacts of safety combination A1 open after the selected delay time has expired. This means that the internal safety relay of the drive (1st shutdown path!) and line contactor K1 (2nd shutdown path!) are no longer energized. Functional Example No. MC-FE-I-001-V11-EN 403 Ex.
