INTRODUCTION
CYCLIC 2020 is a printed circuit board developed by MIL'S and designed to control and monitor medical and
industrial installations that generate vacuum or compressed air using two or three motors.
To ensure personal safety and to avoid any damage to equipment, it is essential to follow the
instructions contained in this document and any other documentation provided with the device,
and particularly the instructions on "Safe Practice".

FUNCTION AND USE OF THE CYCLIC 2020 INDICATOR LIGHTS, KEYS AND SWITCHES
2.1.
The battery
The battery voltage must be measured to check the discharge level. Under a threshold (2.3 V), the saved data
(historic of the last 10 faults from the JBus network) are lost in the event of power cut.
The test is carried out with the powering, then every 24 hours. If the voltage is lower than the threshold, display
indicates "PILE" during 3 seconds every 2 minutes and the buzzer is activated (100ms).
This "alarm" is not managed like a fault: no activation of the alarm exit, no shutdown, no memorizing so no lighting
of the led "? ", no writing in the alarms table of JBus and in the historic of the last 10 faults.

Display card and electronic card
When a communication fault appears between the 2 electronic cards:
The electronic card runs smoothly (regulation and control don't stop),
The display card indicates "E COM" constantly.
Only the display card detects the fault. The electronic card continuously sends data to display. The buzzer,
managed by the electronic card, is not activated.
This "alarm" is not managed like a fault: no activation of the alarm exit, no shutdown, no memorizing so no lighting
of the led "?", no writing in the alarms table of JBus and in the historic of the last 10 faults.
