SECTION 4 |
4.8.2.5.2.1 Option 2 = Generator 0 (This is the Default Option):
This Option will start the Generator at "LOW VOLT ALARM" (Section 4.4.2.8) and stop the Generator when the
batteries are charged based on Charging Profile selected through programming parameter "CHARGING PROFILE"
(Section 4.4.2.21). Further details are given below:
•
If the battery voltage drops to "LOW VOLT ALARM" (Section 4.4.2.8) for continuous period = "GS
DETECT TIME" (Section 4.4.2.16), the Status Relay will be energized. "Common" and "NO" contacts
of the Status Relay will close to initiate automatic starting of the Generator.
•
Once the generator has started and starts feeding AC output (within the programmed limits of voltage
and frequency), the EVO™ will change over from "Inverting Mode" to "Charging Mode". Battery
charging will be initiated as per the Charging Profile set through parameter "CHARGING PROFILE"
(Section 4.4.2.21)
•
Charging will be carried out till the batteries are charged as follows and then, the Status Relay will be
de-energized to stop the generator:
For Parameter "CHARGING PROFILE" (Section 4.4.2.21) set for 3 Stage Charging Profile as per (i)
o
Option "0 = 3 Stg Adaptive", (ii) Option "1 = 3 Stage Type 1" and (iii) Option "2 = 3 Stage Type 2"
The Status Relay will be de-energized to stop the Generator as soon as the battery bank is
•
charged to the voltage threshold set by parameter "FLOATING VOLTAGE" (Section 4.4.2.4)
For Parameter "CHARGING PROFILE" (Section 4.4.2.21) set for 2 Stage Charging Profile as per
o
Option "3 = 2 Stage Type 1"
The Status Relay will be de-energized to stop the Generator when the battery bank is charged
•
to voltage threshold set by parameter "ABSORP VOLTAGE" (Section 4.4.2.2) and remains at this
level for time period set by parameter "ABSORP TIME" (Section 4.4.2.19)
For Parameter "CHARGING PROFILE" (Section 4.4.2.21) set for 2 Stage Charging Profile as per
o
Option "4 = 2 Stage Type 2"
The Status Relay will be de-energized to stop the Generator when the battery bank is charged
•
to voltage threshold set by parameter "ABSORP VOLTAGE" (Section 4.4.2.2) and remains at this
level for time period of 6 min
For Parameter "CHARGING PROFILE" (Section 4.4.2.21) set for 2 Stage Charging Profile as per
o
Option "5 = 2 Stage Type 3"
The Status Relay will be de-energized to stop the Generator when the battery bank is charged
•
to voltage threshold set by parameter "ABSORP VOLTAGE" (Section 4.4.2.2) and subsequently,
the charging current drops to threshold set by parameter "ABSORP EXIT AMPS" (Section
4.4.2.20)
When the Status Relay is de-energized, "Common" and "NO" contacts of the Status Relay will open to initiate automatic
stopping of the Generator. When AC output voltage from the Generator switches off, the EVO
"Inverting Mode".
