Communication; Protections - SLAT AESI 50 W Notice D'utilisation

Battery fault (auxiliary supply):
- If there is no battery (a test will be performed every 30s during the first 20 min after switch on and every 15
min (maximum time interval) then after. In case a fault is detected, another test will be performed every
30s until 20 min have passed from fault end.
If battery voltage < 1.85 V/elt+/-3%.
-
If internal impedance is too high (a tests will be performed every 4 h (maximum time interval) on a loaded
-
battery). Limit values are:
Warnings
Housing version:
3 lights indicate these 3 faults.
Yellow LED warning if fault, green if not.
On motherboard
:
A LED on the motherboard lets the user check the product state before the housing is closed (LED board
unplugged) or when there is no LED board. LED warnings are as followed:
o
Everything OK: green
o
Faults: orange
REMARK: If the cover is removed, a sticker near the LEDs indicates their function. It shows 4 lights. The last
one labelled "NOT USED" is not operating. It has no function.

5.2 Communication

The 3 faults (mains, battery, output) are reported on 3 dry contacts NC NO (positive security).
Dry contact: 1 A @ 24 V DC, 0.3 A @ 125 V AC

5.3 Protections

Against battery polarity inversion before and after switch on.
Against secondary overvoltages thanks to transil diode (regulation troubles or connections mistakes) and auto-
recovery when output voltage > 2.4 V/elt
Against battery wiring error
o
If battery voltage > 2.5 V/elt +/-3%, the battery is not connected
o
If battery voltage < 1.17 V/elt +/-3%, the battery is not connected
Against secondary overcurrent and short-circuits.
Against internal short-circuits thanks to primary fuse.
Against primary overvoltages (due to atmospheric or industrial causes).
