4.7 Auto generAtor StArt / StoP
Auto Generator Start / Stop functionality has been provided using “Common” and Normally
Open “NO” contacts of Status relay (14, fig 2.1). The relay is SPDT Type with contacts rated
at 3A, 125 VAC / 30 VDC. Appropriate external Generator Auto Start / Stop Module will be
required for using this function. 3 options (functions 2, 3 and 4) are available for carrying
out this function depending upon user requirements. Please refer to Sub-Section titled
“Automatic starting and Stopping of Generator (functions 2, 3 and 4)” at page 34 of EVO-
rC Manual at Appendix A.
The “Common” and “NO” terminals are wired to the optional Generator Auto Start /
Stop Control Module which, in turn, is wired to the remote Start / Stop connections on
the Generator. The AC output terminals of the Generator are wired to the Generator Input
Terminals on the EVO
TM
(7, 8, 9 in fig 2.3) for installation details, please refer to Section 3.15
/ fig 3.13 and Section 3.16 / fig 3.14 in the EVO
TM
Manual.

It is recommended that “GSCM-Mini” Series of Generator Start / Stop Control
Module, appropriate for the generator to be used, may ordered directly from
Atkinson Electronics www.atkinsonelectronics.com
based on the Generator Start Logic contained in of one of the selected functions 2, 3 or 4
(explained at Sub-Section titled “Automatic starting and Stopping of Generator (functions 2,
3 and 4)” at page 34 of EVO-rC Manual at Appendix A), 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
TM
(within the programmed limits of voltage
and frequency), the EVO
TM
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
TM
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 functions 2, 3 or 4 (explained
at Sub-Section titled “Automatic starting and Stopping of Generator (functions 2, 3 and 4)”
at page 34 of EVO-rC Manual at Appendix A), 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
TM
will automatically transfer the AC load(s) to the “Inverter
Section” within 16 ms.
