24-04 Fire Mode Max ReferenceRange: Function:Sizerelated*[ par. 24-03 -999999.999FireModeUnit]Maximum value for the reference/setpoint (limiting the sum of value inparameter 24-05 Fire Mode PresetReference and value of signal on inputselected in parameter 24-06 Fire ModeReference Source).If running in open loop when firemode is active, the unit is selected bythe setting parameter 0-02 Motor SpeedUnit. For closed loop, select the unit inparameter 24-02 Fire Mode Unit.24-05 Fire Mode Preset ReferenceRange: Function:0 %* [-100 -100 %]Enter the required preset reference/set point asa percentage of the Fire Mode Max Referenceset in parameter 24-04 Fire Mode Max Reference.The set value is added to the value representedby the signal on the analog input selected inparameter 24-06 Fire Mode Reference Source.24-06 Fire Mode Reference SourceOption: Function:Select the external reference input tobe used for the fire mode. This signalis added to the value set inparameter 24-06 Fire Mode ReferenceSource.[0] * No function[1] Analog Input 53[2] Analog Input 54[7] Pulse input 29[8] Pulse input 33[20] Digital pot.meter[21] Analog input X30/11[22] Analog input X30/12[23] Analog Input X42/1[24] Analog Input X42/3[25] Analog Input X42/524-07 Fire Mode Feedback SourceOption: Function:Select the feedback input to be usedfor the fire mode feedback signalwhen fire mode is active.If the motor also is controlled by thebuilt–in PID controller when innormal operation, the sametransmitter can be used for bothcases by selecting the same source.[0] * No function[1] Analog Input 53[2] Analog Input 5424-07 Fire Mode Feedback SourceOption: Function:[3] Pulse input 29[4] Pulse input 33[7] Analog Input X30/11[8] Analog Input X30/12[9] Analog Input X42/1[10] Analog Input X42/3[11] Analog Input X42/5[15] Analog Input X48/2[100] Bus Feedback 1[101] Bus Feedback 2[102] Bus feedback 3[104] Sensorless Flow[105] Sensorless Pressure24-09 Fire Mode Alarm HandlingOption: Function:[0] Trip+Reset,CriticalAlarmsIf this mode is selected, the frequencyconverter continues to run, ignoring mostalarms, even if doing so may result indamage of the frequency converter. Criticalalarms are alarms, which cannot besuppressed but a restart attempt is possible(infinity automatic reset).[1] * Trip, CriticalAlarmsIn case of a critical alarm, the frequencyconverter trips and does not auto-restart(manual reset).[2] Trip, AllAlarms/TestIt is possible to test the operation of firemode, but all alarm states are activatednormally (manual reset).NOTICEWarranty-affecting alarms. Certain alarms can affect thelifetime of the frequency converter. Should 1 of theseignored alarms occur while in fire mode, a log of theevent is stored in the fire mode-log.Here the 10 latest events of warranty-affecting alarms,fire mode activation, and fire mode deactivation arestored.NOTICEThe setting in parameter 14-20 Reset Mode is disregardedif fire mode is active (see parameter group 24-0* FireMode).Parameter Descriptions Programming GuideMG11CE02 Danfoss A/S © 03/2015 All rights reserved. 1873 3
