HIGH CONDENSATION TEMPERATURE ALARM
If the condensation temperature is too high, due to dirty condenser, the label [HtC] and the room temperature
alternate on the display.
The buzzer sounds.
The buzzer can be turned off by pressing the key
The visual warning signal stays on until the condensation tempertaure returns to normal range.
HIGH CONDENSATION TEMPERATURE ALARM (only on -25°C / -15°C and -22°C /+ 5°C units)
If the condensation temperature is high because the condenser is dirty, the label[ HtC] alternating with the
cell temperature will be shown on the display. A buzzer is also activated.
The buzzer can be turned off by pressing the key
The visual warning signal stays on until the condensation tempertaure returns to normal range.
CONDENSER DIRTY ALARM (only on -25°C / -15°C and -22°C /+ 5°C units)
If the condensation temperature is too high because the condenser is very dirty, the label [dCA] alternating
with the cell temperature will be shown on the display. A buzzer is also activated.
The buzzer can be turned off by pressing the key
The visual warning signal stays on until the condensation tempertaure returns to normal range.
In parallel, the operating set point of the device changes automatically to safeguard plant conditions.
The new setting remains until the condensation temperature returns within the normal range.
HIGH PRESSURE ALARM
If the refrigerating appliance pressure is above the specified limit, the label [HP] and the room temperature
alternate on the display.
The buzzer sounds.
The buzzer can be turned off by pressing the key
The visual warning signal stays on until the card is set to stand-by.
! If the problem causing the alarm reoccurs on restarting the system, the signal [HP] will be displayed again.
In this case, all the relay outputs are de-activated except the condenser fan output.
LOW EVAPORATION TEMPERATURE ALARM (only on -25°C / -15°C and -22°C /+ 5°C units)
If the evaporation temperature is too low because of the packaged evaporator, the label [LtE] alternating with
the cell temperature will be shown on the display. A buzzer is also activated.
The buzzer can be turned off by pressing the key
The visual alarm signal remains until the evaporation temperature returns within the normal range.
If this does not occur, the machine carries out automatic defrosting.
LOW PRESSURE ALARM (only on -25°C / -15°C and -22°C /+ 5°C units)
If a refrigeration system pressure is detected that is lower than the limit values, the label [LP] alternating with
the cell temperature will be shown on the display. A buzzer is also activated.
The buzzer can be turned off by pressing the key
The visual warning signal stays on until the card is set to stand-by.
! If the problem causing the alarm reoccurs on restarting the system, the signal [LP] will be displayed again.
All relay outputs will be deactivated during this event.
