SECTION 4 |
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 "Option "3
o
= 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 "Option "4
o
= 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 "Option "3
o
= 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".
4.8.2.5.2.2 Option 3= Generator 1
This option will start the Generator at "LOW VOLT ALARM" (Section 4.4.2.8) and stop the Generator when the batteries
are charged to the desired programmed level of "RESET VOLTAGE"(Section 4.4.2.7) and stay at this desired level of
voltage or higher for the desired programmed time period = "GEN OFF DELAY" (Section 4.4.2.18).
Further details are given below:
•
If the battery voltage drops to "LOW VOLT ALARM" (Section 4.4.2.8) or lower for continuous period = "GS
DETECT TIME" (Section 4.4.2.16), the Status Relay will be switched ON (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 Charging Profile set by parameter "CHARGING PROFILE" (Section 4.4.2.21).
When the batteries are charged to the desired voltage level set by parameter "RESET VOLTAGE" (Section 4.4.2.7)
•
and stay at this desired level of voltage, or higher for the desired programmed time period = "GEN OFF DELAY"
(Section 4.4.2.18), the Status Relay will be switched OFF (de-energized). "Common" and "NO" contacts of the
Status Relay will open to initiate automatic stopping of the Generator. When AC output from the Generator
switches OFF, EVO™ will change over to "Inverting Mode" (NOTE: The State of Charge of the battery after the
Status Relay has been switched OFF (de-energized) and Generator is stopped will be indeterminate).
