OPTIONAL
15.1 Description
The 24V DC backup power supply module comprises an ELC backup module, two 12V DC batteries assembled in series to produce
24V DC and a 24V DC power supply adjusted to deliver a voltage of 27.3V DC.
Its purpose is to eliminate micro-power cuts on the 24V DC power supply to the hardware.
The purpose of the ELC backup module is:
•
to charge the batteries, controlling the charging current (0.3A)
•
to switch the 24 V DC power supply over to battery power in the event of a 230V power grid outage
•
to check that the batteries are connected the right way round
15.2 Start-up
Switching on the power is sufficient. The ELC module will control the charging of the batteries.
Charging time can be up to 8 hours.
Checking proper operation:
On receipt of the machine and after charging the batteries, disconnect the 230V power supply
protection fuse of the ELC module and check that the PROCOM 2 is still live.
Every year, check that the backup power supply is in good working order using the procedure above.
15.3 Maintenance
The estimated length of service of the 2 batteries is at least 5 years. They must be replaced after 4
years in order to ensure that the backup power supply works properly.
