6.1.5.7 AUTO-OFF "VA"
Press the following sequence of keys to access the menu: 3, 5, 436215, 6:
Automatic Switch-OFF when Output < 0%VA
Adjustment: (5=Toff,Ton) 7=-,8=+
Press key 1 to exit the menu.
Keys 7 and 8 can be used to decrease or increase the percentage threshold of the output load for the AUTO-OFF
function and switching the system to the bypass line; variations of 1% are possible in the field from 0 to 99% of the
rated output load.
For shutdown with mains present, when the output power reaches < of the value set, the battery charge value must be >
60%.
Once this value is reached the system is deactivated.
For shutdown with power output < value set, it must be verified that the battery capacity value is > 60%.
Shutdown is not immediate, but is delayed by the time set as the end of battery discharge pre-alarm (standard value 5
minutes); in this phase the “end of discharge pre-alarm” contact of the remote alarms card is switched, after this time
the output is switched to the bypass line if this voltage is present and the voltage also remains present at the output.
The load remains switched to the bypass line while the output power remains lower than the "AUTO-OFF" value, then
the system waits for an increase in the load before effecting the automatic return to normal operation;
The “AUTO-OFF” function may be used to shut down the system during operation from battery, simply by shutting
down the output load. In normal operation, the “AUTO-OFF” function may be used to reset consumption since the
power circuits are deactivated, the battery remains isolated and only the control circuits, with consumption equivalent to
a light bulb, remain active.
6.1.5.8 AUTO-OFF Timer.
Press the following sequence of keys to access the menu: 3, 5, 436215, 6, 5:
AUTO-OFF Timer: Toff >0: 0', Ton= 0: 0'
ADJUSTMENT: (5=Toff, 6=Ton) 7=-, 8=+
Press key 1 to exit the menu.
The keys have the following functions:
- 6 to modify the value Ton
- 5 to modify the value Toff.
Toff and Ton are time values used by the system to affect an automatic daily shutdown and restart cycle.
The timer cycle is inhibited when Toff = Ton.
When the internal clock reaches the time Toff, if the mains voltage is present and the percentage of recharge is less than
60%, only the following is displayed:
AUTO-OFF Timer: Toff= 20:00', Ton= 7:00'
H100, OUT100% BATT= 50%Ah 5=ON
The system waits until the battery recharge exceeds the value of 60% before deactivating.
When the internal clock reaches the time Toff ( 20:00' ), if the mains voltage is present and the percentage of recharge is
greater than 60%, or the mains voltage is not present and operation is from battery, the following is displayed:
AUTO-OFF Timer: Toff= 20:00', Ton= 7:00'
H100, OUT100% OFF:4 min 5=ON
