UK !!! 6. RS485 SERIAL LINE The MIR70 model can be connected, even afterwards, to a XJ500 monitoring and supervising system. This is possible thanks to the outputs for the XJRS485 external serial module that provides a standard output RS485. 7. ALARM SIGNALS Message Description Outputs “rEr” Remote control Outputs according to the external thermostat signals “PAL” Digital input alarm Alarm output ON; Other outputs OFF “P1” Cold room probe failure Alarm output ON; Compressor output according to "CSP" parameter “P2” Evaporator probe failure Alarm output ON; Other outputs unchanged; Timecontrolled defrost end “LA” Low temperature alarm Alarm output ON; Other outputs unchanged “HA” High temperature alarm Alarm output ON; Other outputs unchanged “EAL” Vacuum function error Alarm output ON; Other outputs OFF “noL” Missing data transmission between electronic control panel and keyboard All the signals different from the ones specified in this manual indicate a serious damage to the electronic control panel. 8. ALARM RECOVERY MODE The probe alarms "P1" and "P2" trip 30 seconds after the occurrence of a fault in the related probe; they stop automatically 30 seconds after the probe restarts normal operation. Check connections before replacing the probe. High and low temperature alarms stop automatically both as soon as the thermostat temperature returns to normal values and when defrost starts. The external alarm "PAL" stops, as soon as the external digital input is disconnected. 9. CONNECTION SCHEMES 20
