9.5. Energy Backup
The ATyS C65 has an internal energy backup that will keep the ATS controller powered for up to 30 seconds. This setting is
congured to 15 seconds by default and can be modied inside the maintenance menu "MAIN MENU" > "MAINTENANCE" >
"ENERGY BACKUP". The energy backup will activate when both sources are not available and there is no DC power supply
included. The backup energy will keep the main functions of the controller powered so as to inform the user about the ATSE
status as follows:
- ATS function (sensing, automatism, relays, genset start…)
- Display screen (with backlight)
- Menus navigation and control pushbuttons
- Communications
Note: the Energy backup will supply the ATyS C65 controller excluding accessories such as I/O or other digiware
connected devices.
Note: during backup time, inputs will keep their last state in memory, position return information will become blind
(position LED info blinking).
Monostable relays (OUT1 to 4) are still working during the rst 15s, then they will be deativated to minimize power
consumption.
In case the 2 latching relays (OUT5 and OUT6, contacts 51-54 and 61-64) were not driven during energy backup
time (controller is now OFF), they will automatically change state after the prioritary source Fail timer is over to start
the generator(s) using their own independent backup power. Even if the controller is off, the application is still able
to start the genset with respect of the failure timer of the prioritary source (maximum delay is 60s, even if failure
timer is congured at a higher value)
9.6. Current Measurement
Current measurement can be done with current transformers by connecting the secondary of the transformer between the
phases I1, I2, I3 and the GND. Neutral can be measured using an additional current transformer. If this is not tted the neutral
current will be calculated using the phase values.
Current transformer’s secondary should be /1A or /5A and this conguration needs to be set in "MAIN MENU" >
"PARAMETERS" > "LOAD". The accuracy of the current measurement on the controller is +/- 1%.
Recommended cable cross sectional area: 1,5mm
