4.3. Alarms management
CYCLIC 2020 use the backed‐up memory for the current variables (parameters and record of the last
10 faults transferred by JBUS). The current faults are not stored during a main power failure.
The key is therefore "empty" each time power is switched back on (no faults stored).
4.3.1. The key
If a fault occurs, the LED comes on steady and this fault is stored.
Holding this key pressed, when the LED is on, causes the display of all the faults affecting motors A, B and C since
powering on (or the last fault acknowledgement) as follows:
The "motor X control" indicator flashes slowly: motor X has reached its upper limit.
The "motor X fault" indicator comes on steady: there is a fault on motor X.
The "room temperature fault"
there has been a high temperature fault (room temperature > 45°C).
there has been a low temperature fault (room temperature < 5°C).
The "network pressure fault"
there has been a network high (air) or low (vacuum) pressure alarm.
back‐up cylinders are engaged or there has been a cylinder
frames pressure fault on the system.
there has been a control pressure alarm on the system.
With per‐line hygrometry management:
The "motor X fault" indicator flashes slowly: there has been a hygrometry fault on motor X.
The "hygrometry fault" indicator comes on steady: there is a hygrometry fault on a motor.

With independent hygrometry management:
The "motor A or B fault" indicator flashes slowly: there has been a hygrometry fault on A or B air treatment unit.
The "hygrometry fault" indicator comes on steady: there is a hygrometry fault on an air treatment unit.
If the "hygro probe out of service" fault is stored, and by pressing the key, the display indicates "H LL".
4.3.2. Motor fault
When the "motor fault" on/off input is inactive, the corresponding motor is considered to be invalid.
The motor cannot run and the corresponding red "motor fault" indicator
This fault is not taken into account at shutdown. When the motor receives the start‐up signal, this fault is masked
for 90 seconds: if it disappears during these 90 seconds the motor continues running. If the fault occurs during
operation, it will be taken into account after the 90 seconds timeout.
The "alarm synthesis" relay and the buzzer are activated by the fault.
The fault is automatically cleared when the contact becomes active again (as are the "alarm synthesis" and the buzzer).
This fault is stored and can be displayed by pressing the
If a motor is in "motor fault" condition, the next motor in the line starts up immediately.
4.3.3. Upper limit time
When the motor has been running for longer than the upper limit time, the "motor control" indicator
flashes slowly and the next motor in the line starts up.
An upper limit time fault appears when all the motors (2 or 3 depending on setting of switch SW 2.6) have each run
for the upper limit time set with the switches (SW 2.5) and (SW 2.4).
The buzzer and the alarm synthesis are activated.
The fault is automatically cleared when the motors stop (as are the "alarm synthesis" and the buzzer).
This fault is stored and can be displayed by pressing the
The "infinite" position of switches (SW 2.5) and (SW 2.4) inhibits this upper limit time phenomenon.
Note: When the top‐up motor enables the maximum pressure to be reached, the first motor stops.
The second motor stops if FLEXO mode is not selected, otherwise it runs for the forced operation time selected with
switches (SW2.2) and (SW2.1)
comes on steady.
