EN - 30
Display:
► If ≥ 5 shutdowns occur in 24 hours
● If a fault occurs:
- Compressor turned off.
- Circuit fault output on.
- Circuit X discharge temperature fault relay on optional board in On position.
- Circuit LED on console lit steadily.
- The number of faults over a 24 hour period is managed.
Display:
● Resetting:
- If the number of faults in 24 hours < 5, the fault is automatically acknowledged provided the discharge temperature ≤ P51 –20°C and the
5-minute time delay has elapsed.
- If the number of faults in 24 hours ≥ 5, the fault is acknowledged provided the discharge temperature ≤ P51 –20°C and the RESET button on
the console is pressed.
6.12 High-pressure switch fault on circuit 1, 2 or 3
● Operation :
- These three inputs monitor the state of the HP pressure switches on each refrigerating circuit.
- They are associated with the operation of their respective circuits.
- They are read 3 seconds after the compressor starts up (due to wiring)
● If a fault occurs:
- Compressor turned off.
- Circuit fault output on.
- Circuit X HP fault relay on optional board in On position.
- Circuit LED on console lit steadily.
Display:
● Resetting:
- Reset the high-pressure switch manually then acknowledge the fault by pressing RESET.
6.13 LP fault on circuit 1, 2 or 3
● Operation :
- If the pressure measured by the LP pressure transmitter is ≤ P55, the Xtraconnect 2 controller records an LP fault.
- The low pressure is monitored 120 seconds after the compressor starts up (it is also monitored when the compressor is stopped).
► If < 3 shutdowns occur in 24 hours
● If a fault occurs:
- Compressor turned off.
- Circuit fault output off.
- Circuit X LP fault relay on optional board in Off position.
- Circuit fault LED on console flashes.
- The number of faults over a 24 hour period is managed.
Display:
► If ≥ 3 shutdowns occur in 24 hours
● If a fault occurs:
- Compressor turned off.
- Circuit fault output on.
- Circuit X LP fault relay on optional board in On position.
- Circuit fault LED on console lit steadily.
- The number of faults over a 24 hour period is managed.
Display:
● Resetting:
- If the number of faults in 24 hours < 3, the fault is automatically acknowledged provided LP > P55 + 1b.
- If the number of faults in 24 hours ≥ 3, the fault is acknowledged provided the LP > P55 + 1b. and the RESET button on the console is
pressed.
