Samlexpower Evolution EVO-2212 - RELAY FUNCTION:

32 | SAMLEX AMERICA INC. SAMLEX AMERICA INC. | 33
APPENDIX A
RELAY FUNCTION:
A Single Pole Double Throw (SPDT) Status Relay with 3 contacts has been provided that can be
used for (i) signaling of operational status (Functions 0 and 1) and (ii) providing contact closure
/ opening for automatic starting and stopping of generator through appropriate optional
Generator Auto Start / Stop Control Module (Functions 2, 3 and 4). The 3 contacts of the
Status Relay are connected to 3 terminals of Terminal Block (14, Fig 2.1) 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 parameter and details of 5
different associated Functions 0 to 4 are provided in the succeeding paragraphs
Signaling of Operational States (Functions 0 and 1)
0 = Charger/Other: When the EVO Inverter Charger 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]
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, the Status Relay will be ON (energized) [(i) Common and “NO”
contacts will close and (ii) “Common” and “NC” contacts will open].
