Depending on the configuration, the followingsources can reset the safety option:• The Reset key on the LCP or the frequencyconverter’s digital input.• The digital input on the safety option (DI2_A).• The reset signal via the safe fieldbus.• The automatic reset function.Parameter 42-24 Restart Behaviour determines whether thesafety option restarts automatically, or waits for a manualreset after the safety function was activated:• Manual reset behaviour - when the safetyfunction is activated, the safety option requires areset from a reset source before it can run again.• Automatic reset behaviour - when the safetyfunction is activated, the safety option can runagain as soon as the condition that triggered thesafety function ceases. This behaviour is onlyvalid for the digital input where this resetbehaviour is defined. For instance, in case of anexternal error, a manual reset from the resetsource is required regardless of the setting in42-24 Restart Behaviour.For more information, read the description of 42-31 ResetSource and its options in chapter 7.1 Parameter List.6.3.1 Reset Input (DI2)If manual reset is configured, wire the DI2A reset inputterminal to a 24 V DC via an NO switch. The manual resetcan also be used to reset external errors detected by thesafety option.Configuring the Safety Opti... Safety Option MCB 15222 Danfoss A/S © 10/2014 All rights reserved. MG37F10266 |
