A Single Pole Double Throw (SPDT) Status Relay with 3 contacts (Contact Rating: 3A ; 125 VAC / 30 VDC) has been
provided in the Evolution™ Series (EVO™) Inverter/Chargers EVO-2212 / 3012 / 2224 / 4024 that can be used for (i)
signaling of operational status [Options 0 and 1 - See Section 4.8.2.5.1] and (ii) providing contact closure / opening
for automatic starting and stopping of generator through appropriate optional Generator Auto Start / Stop Control
Module (Options 2, 3 and 4 - See Sections 4.8.2.5.2.1 to 4.8.2.5.2.3). The 3 contacts of the Status Relay are connected
to 3 terminals of Terminal Block (14, Fig 2.1 in Owner's Manual for Evolution™ Series Models EVO-2212 / 3012 / 2224
/ 4024) on the front panel. The contacts are marked “NO” (Normally Open), “Common” and “NC” (Normally Closed).
When the Status Relay is OFF (de-energized), contacts marked “Common” and “NO” will be in open condition and
contacts marked “Common” and “NC” will be in closed condition. When the Status Relay is ON (energized), contacts
marked “Common” and “NO” will close and contacts marked “Common” and “NC” will open.
Diagram showing steps for programming the RELAY FUNCTION (Table 4.8, Screen No.5) parameter and details of 5
different associated Options 0 to 4 are provided in the succeeding paragraphs.
4.8.2.5.1 Signaling of Operational States (Options 0 and 1)
NOTE: Applicable for Models EVO-2212 / 3012 / 2224 / 4024 ONLY.
a) Option "0 = Charger/Other": When the EVO™ Inverter/Charger Model EVO-2212 / 3012 / 2224 / 4024
is in “Charging” Mode, the Status Relay will be OFF (de-energized) [(i) “Common” and “NO” contacts will be
in open condition and (ii) “Common” and “NC” contacts will be in closed condition]. In “Other” operating
modes i.e. in “Inverting”, “Power Save” or in “Standby” Modes, the Status Relay will be ON (energized)
[(i) Common and “NO” contacts will close and (ii) “Common” and “NC” contacts will open].
b) Option "1 = Normal/Fault": When in “Normal” operational state i.e. when not in Fault Mode, the Status
Relay will be OFF (de-energized) [(i) “Common” and “NO” contacts will be in open condition and (ii) “Common”
and “NC” contacts will be in closed condition]. When the EVO™ Inverter/Charger is in “Fault” mode (Table 7.1),
the Status Relay will be ON (energized) [(i) Common and “NO” contacts will close and (ii) “Common” and “NC”
contacts will open].
INFO
A 12V, 100mA capacity DC source has been provided in EVO-2212/ 3012/ 2224/ 4024 (16 in Fig 2.1 of the
Owners Manual for EVO-2212/ 3012/ 2224/ 4024). This 12V DC source may be used to drive 12V rated
signalling device through the contacts of the Status Relay for the above 2 options (Options 0 & 1).
4.8.2.5.2 Automatic Starting and Stopping of Generator (Options 2, 3 and 4)
NOTE: Applicable for Models EVO-2212 / 3012 / 2224 / 4024 ONLY.
The Normally Open “NO” and “Common” contacts of Status Relay (14, Fig 2.1 in the Owner's Manual for Evolution™
Series Inverter/Charger Models EVO-2212 / 3012 / 2224 / 4024) can be used to also automatically start and stop generator
through appropriate external Generator Auto Start / Stop Module. 3 options (Options 2, 3 and 4 - See Sections 4.8.2.5.2.1
to 4.8.2.5.2.3) explained below are available for carrying out this function depending upon user requirements. 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™ (7, 8, 9 in Fig 2.3 in Owner's Manual for EVO™ Series Inverter/Charger
Models EVO-2212 / 3012 / 2224 / 4024). For installation details, please refer to Section 3.17 / Fig 3.14 and Section 3.18
/ Figs 3.15A & B in the Owner's Manual for EVO™ Series Inverter/Charger Models EVO-2212 / 3012 / 2224 / 4024.
