Parameter Setup
Relay Options 2, 3 and 4 related to automatic starting and stopping of generator are explained below:
4.8.2.5.2(a) Option 2 = Generator 0 (This is the Default Option):
This Option will start the Generator at “LOW VOLT ALARM” and stop the Generator when the
batteries are fully charged till completion of 3-Stage Charging Cycle.
• If the battery voltage drops to “LOW VOLT ALARM” [(i) for 12V: 9.5V – 12.5V / Default 11.0V
(ii) for 24V: 19.0V – 25.0V / Default 22.0V] or lower for continuous period = “GS DETECT
TIME” (0-600 sec; Default 10 sec), 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
TM
will change over from “Inverting Mode” to
“Charging Mode”. Battery charging will be initiated as per full and complete 3-Stage
Charging Algorithm ("EQUALIZE-4STAGES", Option 0 = No).
• On entering “Float Stage” on completion of “Absorption Stage”, 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
TM
will change over to “Inverting Mode” (
NOTE:
The battery will be charged to 100%
State of Charge after the Transfer Relay has de-energized on entering Float Stage).
4.8.2.5.2 (b) Option 3 = Generator 1
This Option will start the Generator at “LOW VOLT ALARM” and stop the Generator when the
batteries are charged to the desired programmed level of voltage (“RESET VOLTAGE”) and stay at
this desired level of voltage or higher for the desired programmed time period = “GEN OFF DELAY”.
• If the battery voltage drops to “LOW VOLT ALARM” [(i) for 12V: 9.5V – 12.5V / Default 11.0V (ii)
for 24V: 19.0V – 25.0V / Default 22.0V] or lower for continuous period = “GS DETECT TIME” (0-
600 sec; Default 10 sec), 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
TM
will change over from “Inverting Mode” to
“Charging Mode”. Battery charging will be initiated as per full and complete 3-Stage
Charging Algorithm (“EQUALIZE-4STAGES”, Option 0 = No).
• When the batteries are charged to the desired programmed level of voltage = “RESET
VOLTAGE” [(i) for 12V: 12.0V – 17.0V / Default 14.0V (ii) for 24V: 24.0V – 35.0V / Default
28.0V] and stay at this desired level of voltage, or higher for the desired programmed
time period = “GEN OFF DELAY” (0-240 min; Default 60 min), 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
TM
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).
4.8.2.5.2 (c) Option 4 = Generator 2
This Option will start the Generator at “LOW VOLT ALARM” and stop the Generator after the
desired programmed value of run time of the Generator = “GEN ON TIME” (0-240 min; Default
= 60 min) counted from the time the Status Relay is switched ON (energized).
