5. POWER SUPPLY OPERATION
Mains fault (normal source) :
signalled locally by a yellow LED and remotely by dry contact with delay (failsafe).
• If the mains is not present or < 195 V.
• If the mains fuse is blown or not present.
• If the product is out of service.
Battery fault (emergency power) :
signalled locally by a yellow LED and remotely by dry contact with delay (fail-
safe).
•
If the battery is not present : The battery test is performed in the following manner: every 30 seconds for the first 20
minutes after commissioning : every 15 minutes after the first 20 minutes. If a fault is detected, the test is performed
every 30 seconds up to 20 minutes after the fault disappears.
•
If the internal impedance is too high (test every 4 hours maximum on a charged battery).The impedance limit
value is :
• If the battery voltage :
No voltage on one of the Outputs :
signalled locally by a yellow LED and remotely by dry contact with delay (fail-
safe).

5.2 SUMMARY OF AVAILABLE EQUIPMENT
Temperature compensation :
A battery voltage compensation system maintains the charge characteristics within the limits specified by the
battery manufacturer across the entire operational temperature range.
Battery low voltage cut-out :
The cut-out threshold is :
The element causing the cut-out will be in the + position.
