Document 57.4403.4200 GTH-4013 SX GTH-4017 SX 29May 2008 Section 2 - Technical SpecificationTECHNICAL SPECIFICATIONAlarm code 4Description Block Relay check error during work. Check through.re-reading of the block outputof the congruence with the current state of the limiter.The alarm triggers even in the absence of malfunctions if the load limiter cutoutkey is used.Action The relay or the cable can be shorted; check.The limiter’s outputs do not deactivate. Switch off and on the machine and run a completetest of the outputs.If the alarm persists, replace the DLE.Alarm code 5-8Description Block Relay check error at start. When the instrument is started, the re-reading of theblock output is always OFF except when the two outputs of the DLE are connected inseries.5 - DLE output 0V or low voltage - 12V re-reading8 - DLE output 12V - ow voltage or 0V re-readingThe alarm triggers even in the absence of malfunctions if the load limiter cutoutkey is used when the instrument is started.Action The relay or the cable can be shorted; check.The limiter’s outputs do not deactivate. Switch off and on the machine and run a completetest of the outputs.If the alarm persists, replace the DLE.Alarm code ADescription RAM data error. Checks that the parameters load in the RAM at start-up remain unal-tered.Action Switch off and on the limiter.Alarm code BDescription Outriggers congruence.Action Check that the signal of stabilised machine is congruent between the two inputs usedfor reading during operation.Display: until the system is turned off.Operations: check wiring, power cable, DLE connector. If the alarm persists, change theDLE (digital input reading malfunction).Alarm code CDescription A.D.C. reading control error. If the analog/digital converter works fine after specialrereading of the DLE board.Action Switch off and on the limiter.If the alarm continues, replace DLE.CHECK THE SYSTEM USING WINSCOPEConnect the PC to the LMI display (limit moment indicator) using the serial port and the power cord (cod.07.0736.0014), switch on the board and start the Winscope application.Below, the list of the parameters and of the variables visualizable on the PC.
