selection [4] PTC 1 Alarm or [5] PTC 1 Warning is chosen bymistake and the external safety device triggers Safe Stopthen the frequency converter issues an alarm ”DangerousFailure [A72]” and coast the frequency converter safely,without Automatic Restart.Selections [6] PTC 1 & Relay A to [9] PTC 1 & Relay W/A mustbe chosen for the combination of external safety deviceand MCB 112.NOTENote that selections [7] PTC 1 & Relay W and [8] PTC 1 &Relay A/W open up for Automatic restart when the externalsafety device is de-activated again.This is only allowed in the following cases:1. The unintended restart prevention isimplemented by other parts of the Safe Stopinstallation.2. A presence in the dangerous zone can bephysically excluded when Safe Stop is notactivated. In particular, paragraph 5.3.2.5 of ISO12100-2 2003 must be observed.See 9.8 MCB 112 PTC Thermistor Card and the operatinginstructions for the MCB 112 for further information.3.12.3 Safe Stop Commissioning TestAfter installation and before first operation, perform acommissioning test of an installation or application makinguse of Safe Stop.Moreover, perform the test after each modification of theinstallation or application, which the Safe Stop is part of.NOTEA passed commissioning test is mandatory after first instal-lation and after each change to the safety installation.The commissioning test (select one of cases 1 or 2 asapplicable):Case 1: restart prevention for Safe Stop is required (i.e.Safe Stop only where 5-19 Terminal 37 Safe Stop is set todefault value [1], or combined Safe Stop and MCB112where 5-19 Terminal 37 Safe Stop is set to [6] or [9]):1.1 Remove the 24 V DC voltage supply toterminal 37 by the interrupt device while themotor is driven by the FC 302 (i.e. mains supply isnot interrupted). The test step is passed if themotor reacts with a coast and the mechanicalbrake (if connected) is activated, and if an LCP ismounted, the alarm “Safe Stop [A68]” isdisplayed.1.2 Send Reset signal (via Bus, Digital I/O, or[Reset] key). The test step is passed if the motorremains in the Safe Stop state, and themechanical brake (if connected) remainsactivated.1.3 Reapply 24 V DC to terminal 37. The test stepis passed if the motor remains in the coastedstate, and the mechanical brake (if connected)remains activated.1.4 Send Reset signal (via Bus, Digital I/O, or[Reset] key). The test step is passed if the motorbecomes operational again.The commissioning test is passed if all four test steps 1.1,1.2, 1.3 and 1.4 are passed.Case 2: Automatic Restart of Safe Stop is wanted andallowed (i.e. Safe Stop only where 5-19 Terminal 37 SafeStop is set to [3], or combined Safe Stop and MCB112where 5-19 Terminal 37 Safe Stop is set to [7] or [8]):2.1 Remove the 24 V DC voltage supply toterminal 37 by the interrupt device while themotor is driven by the FC 302 (i.e. mains supply isnot interrupted). The test step is passed if themotor reacts with a coast and the mechanicalbrake (if connected) is activated, and if an LCP ismounted, the warning “Safe Stop [W68]” isdisplayed.2.2 Reapply 24 V DC to terminal 37.The test step is passed if the motor becomes operationalagain. The commissioning test is passed if all two teststeps 2.1 and 2.2 are passed.NOTESee warning on the restart behaviour in 3.12.1 Terminal 37Safe Stop FunctionIntroduction VLT® AutomationDrive FC 300 Design Guide, 0.25-75 kW58 MG33BE02 - VLT® is a registered Danfoss trademark33RSPSupply - 1-888-532-2706 - www.RSPSupply.comhttp://www.RSPSupply.com/p-21462-Danfoss-131B8966-VLT-Automation-VT-Drive-VFD-FC301-230V-5-HP.aspx
