C1-06: Load Support Level
•
This setting is a special setting for load support mode when the Combi-Gamma is charg-
ing and due to a sudden load, the AC IN current exceeds the AC IN Current Limit (B2-
05), the Combi-Gamma will switch to load support mode (when C1-05=1)
•
At that moment, the current need is unknown. The Combi-Gamma makes an assump-
tion of the magnitude of this current. This assumption is equal to AC IN Current Limit
(B2-05) multiplied by this Load Support Level (C1-06). The default factor is two.
•
This will prevent the circuit breaker from tripping because current provided by the IN-
VERTER minus the current drawn by the load is always lower than the rating of the cir-
cuit breaker. This happens, of course, when the AC IN Current Limit (B2-05) is correctly
adjusted on the circuit breaker.
•
If for instance in a
IN Current Limit (B2-05)(Normal load of generator is lower than maximum peak load) and
one knows that the load which is switched on always draws a certain current, one can con-
sider to increase this factor (C1-06) to achieve better results with sudden load changes.

The
Adaptive (D1-02=2) and Adaptive +Battery safe (D1-02=3) curve derive the Ab-
sorption time from the Bulk time. The maximum Absorption time of these charge curves
is determined by Absorption Time (D1-06) setting.
•
The
Adaptive + Battery safe (D1-02=3) curve has a special regulation in the absorption
phase. The absorption phase will start when the battery voltage reaches 14.4V( for 12V
batteries) regardless of the specified Absorption Voltage (D1-03). During the absorption
phase, the voltage will increase with a fixed ramp until the voltage reaches the absorp-
tion voltage or the calculated absorption time is over in the latter case, the absorption
phase will end before the absorption voltage is reached.
