on the EVO™ (7, 8, 9 in Fig 2.3 in the attached Owner's Manual for EVO-2212/3012/2224/4024). For installation
details, please refer to Section 3.17 / Fig 3.14 and Section 3.18 / Fig 3.15A & B in the attached Owner's Manual for

INFO
It is recommended that "GSCM-Mini" Series of Generator Start / Stop Control Module, appropriate for the
generator may be considered and ordered directly from Atkinson Electronics www.atkinsonelectronics.com
Based on the Generator Start Logic contained in of one of the selected Options 2, 3 or 4 explained below (See Sections
4.8.2.5.2.1 to 4.8.2.5.2.3), the Status Relay will be switched ON (energized), its "Common" and "NO" contacts will
close and the external Generator Start / Stop Control Module will initiate automatic starting of the Generator. Once the
Generator has started and starts feeding AC output to EVO™ (within the programmed limits of voltage and frequency),
the EVO™ will be synchronized with the Generator and once synchronization is completed, the load will be transferred
instantly (within 1 ms) to the Generator at Zero Crossing of the voltage waveform for seamless transfer and for better
protection of Transfer Relay contacts. The EVO™ will now operate in "Charging Mode" with the AC power from the
Generator charging the batteries as well as providing power to the AC load(s).
Based on the Generator Stop Logic contained in one of the selected Options 2, 3 or 4 explained below (See Sections
4.8.2.5.2.1 to 4.8.2.5.2.3), the Status Relay will be switched OFF (de-energized), its "Common" and "NO" contacts will
open and the external Generator Auto Start Control Control Module will initiate automatic stopping of the Generator.
When AC output of the generator is shut down, the EVO™ will automatically transfer the AC load(s) to the "Inverter
Section" within 16 ms.
Options 2, 3 and 4 of Parameter "RELAY FUNCTION" related to automatic starting and stopping of generator are
explained below under Sections 4.8.2.5.2.1 to 4.8.2.5.2.3:
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 the 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 that has been set
by parameter "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) "Option
