 Voltage Start
Three starting voltages are available. These are low-voltage set points
which are linked to times of 24 hours, 2 hours, and 2 minutes.
These
times indicate how long the batteries should be left at a particular low voltage be
fore starting
the generator for recharge.
 If the battery voltage drops below any of these set points, that timer starts counting down.
 If the voltage is above the set point, the timer counts up again.
 When any timer reaches zero (0), a start command is sent to the generator.
 The timers automatically reset to maximum when AGS stops the generator, or upon an AGS fault.
 See page 29 to view these timers.
After a generator runs due to Voltage Start, it will be stopped when the inverter completes the battery
charging cycle.
 Load Start
The generator can start whenever the system AC load exceeds the
Start wattage for the programmed Delay time. The generator is
stopped when the AC load drops below a Stop set point for the
Delay time.
 State-of-Charge (SOC) Start
Occasionally it is not effective for the generator to start on the basis of
voltage. AGS can operate the generator based on battery SOC information
from the FLEXnet DC battery monitor (FN-DC).
 Enable — Y (Yes) causes the MATE3s to start and stop the generator based on the items below. N (no) disables
this function.
 Start SOC — When the FN-DC shows an SOC below this setting (0 to 99%), the generator starts. (The SOC value is
displayed on the Home screen. See the MATE3s Overview Guide.)
 Stop SOC — When the FN-DC shows that the SOC has exceeded this setting (0 to 100%), the generator stops.
NOTE: In some cases the charger may not easily reach a setting of 100% SOC. It is recommended to set Stop SOC
no higher than 98%.
IMPORTANT:
If DC Generator is set to Y, the generator will only stop after reaching the DC generator
parameters shown on page 25.
 24 Hour Start Enable — enables (Y) or disables (N) the 24-hour timer. Voltage should be set for a mild discharge.
The range varies with battery voltage.
 2 Hour Start Enable — enables (Y) or disables (N) the 2-hour timer. Voltage should be set for a major discharge.
The range varies with battery voltage.
 2 Minute Start Enable — enables (Y) or disables (N) the 2-minute timer. Voltage should be set for a critical battery
discharge and an emergency generator start. The range varies with battery voltage.
NOTE: The Quiet Time settings overrides the settings and prevents an automatic start. The exception is 2 Minute Start.
As an emergency set point, it will start the generator regardless of Quiet Time settings.
 Enabled — either enables (Y) or disables (N) the Load Start function.
 Start — the load size (0 to 50 kW) which requires the generator to start following the Delay time (1 to 240 minutes).
 Stop — the lower load setting (0 to 49 kW) which ends the generator operation following the Delay time (1 to 240 minutes).
If Stop SOC is not desirable, AGS can stop the generator by another means.
 Enable Full Charge — When set to Y (yes), the MATE3s completes a full charging cycle regardless of Stop SOC.
 Interval — the days (1 to 30) before Enable Full Charge is used.
The MATE3s will perform Start SOC as normal. The MATE3s compares the Interval period against the
Days Since Parms Met display. (See the MATE3s Overview Guide.) If Days Since Parms Met is equal
or higher, then the generator will run until the FLEXnet DC's charge parameters are met, regardless of the
SOC value. (See page 31 for more information.)
After the cycle is over, the SOC is automatically reset to 100% when the batteries begin to discharge for
one minute.
Setting Enable Full Charge to N or setting the Interval to zero (0) days will disable the function.

IMPORTANT:
 Large, instantaneous loads can still overload the inverter if the generator does not start in time.
 When the generator is running because of Load Start, the inverter will charge the batteries.
However, it is not programmed to perform a complete charge cycle. If the generator reaches its
Stop point, the charge might not be completed.
 Enable — either enables (Y) or disables (N) the Must Run function.
 Weekday Start — the daily time (00:00 to 23:59, Monday through Friday) when the generator must start.
 Weekday Stop — the daily time (00:00 to 23:59, Monday through Friday) when the generator must stop after Weekday Start.
 Weekend Start — the daily time (00:00 to 23:59, Saturday and Sunday) when the generator must start.
 Weekend Stop — the daily time (00:00 to 23:59, Saturday and Sunday) when the generator must stop after Weekend Start.
The Must Run Schedule is disabled when Start and Stop are set to the same time, or if Enable is set to N.
 Must Run Schedule
This is a period of time when the generator is commanded to run
regardless of other conditions. This is usually set because large loads are
expected to be present. Must Run Schedule times can be set individually
for weekdays and weekends.
