9.4 Protection SimulationNOTICEProtection simulation is protected by the security accesscode.To test the operation and control circuits of the soft starterwithout connecting it to mains voltage, use the softwaresimulation functions.The protection simulation feature enables the soft starterto confirm that it responds correctly and reports thesituation on the display and across the communicationnetwork.To use the protection simulation:1. Open the Main Menu.2. Scroll to Protection Sim and press [OK].3. To select the protection to simulate, press [▲] and[▼].4. To simulate the selected protection, press [OK].5. The screen is shown while [OK] is pressed. Thesoft starter response depends on the protectionaction setting (parameter group 16 ProtectionActions).6. To return to the simulation list, press [Back].7. To select another simulation, press [▲] or [▼], orpress [Back] to return to the Main Menu.MS1 000.0A 0000.0kWTrippedSelected ProtectionTable 9.5 Protection Simulation MenuNOTICEIf the protection trips the soft starter, reset beforesimulating another protection. If the protection action isset to Warn or Log, no reset is required.If the protection is set to Warn & Log, the warningmessage can be viewed only while [OK] is pressed.If the protection is set to Log only, nothing appears onthe screen but an entry appears in the log.9.5 Output Signal SimulationNOTICEThe security access code protects the output signalsimulation.The LCP allows simulation of output signaling to confirmthat the output relays are operating correctly.NOTICETo test operation of the flags (motor temperature andlow/high current), set an output relay to the appropriatefunction and monitor the relay behavior.To use the output signal simulation:1. Open the Main Menu.2. Scroll to Output Signal Sim and press [OK], thenenter the access code.3. To select a simulation, press [▲] and [▼], thenpress [OK].4. To turn the signal on and off, press [▲] and [▼].To confirm correct operation, monitor the state ofthe output.5. To return to the simulation list, press [Back].Prog Relay AOffOnTable 9.6 Output Signal Simulation Menu9.6 Digital I/O StateThis screen shows the status of the Digital I/O in order.The top line of the screen shows:• Start.• Stop.• Reset.• Programmable input.The bottom line of the screen shows programmableoutputs A, B, and C.Digital I/O StateInputs: 0100Outputs: 100Table 9.7 Digital I/O Status Screen9.7 Temp Sensors StateThis screen shows the state of the motor thermistor.The screen shot shows the thermistor state as O (open).Temp Sensors StateThermistor: OS = shrt H=hot C=cld O=opnTable 9.8 Motor Thermistor Status ScreenTools Operating GuideMG17K602 Danfoss A/S © 05/2016 All rights reserved. 739 9
