Temperature fault
When power is switched on, there is a 30‐second temperature fault masking timeout.
If the probe is disconnected, the "high temperature" alarm is activated, the fan is actuated and the display shows
"tt" when the room temperature is consulted.
Note: if only the "signal" wire (terminal 49) is disconnected, the value displayed is 67°C.
If the temperature rises above 45°C, the "temperature fault"
The "alarm synthesis" relay and the buzzer are activated.
There is a 5‐second timeout before the fault is taken into account.
The fault is automatically cleared when the temperature falls below the threshold ‐ hysteresis.
This alarm has no effect on the motors.
This fault is stored and can be displayed by pressing the
If the temperature falls below 5°C, the "temperature fault"
The "alarm synthesis" relay and the buzzer are activated.
There is a 5‐second timeout before the fault is taken into account
The fault is automatically cleared when the temperature rises above the threshold + hysteresis.
This alarm has no effect on the motors.
This fault is stored and can be displayed by pressing the
If the temperature exceeds the fan cut‐in threshold (parameter "t"), the "fan" relay is activated.
There is a 5‐second timeout before exceeding of the threshold is taken into account.
The relay automatically opens when the temperature falls below the threshold ‐ hysteresis (‐2°C).
This has no effect on the motors.

Clearing faults
After having noted the faults and taken the necessary steps, pressing the
simultaneously clears all the faults. The LED goes out, except if there is also a fault.

JBUS ‐ RS 485 SERIAL LINK
This link allows the main data transfer from CYCLIC 2020 to:
‐ either a networked remote monitoring system,
‐ or to one or two REPORT STATUS units, see Manual No.514584. for more detailed information.
Note: the CYCLIC 2020 can't be simultaneously connected to a remote monitoring system and 1 or 2 REPORT
STATUS units.
The CYCLIC 2020 address can be adjusted from 0 to F by a coding wheel on the CYCLIC 2020 board to the
switches.
The data transferred over the link are read‐only data with an updating interval of 10 seconds.
