To control lighting circuits where a Photoelectric control
turns “ON” at dusk and “OFF” by preset times of 120VAC
controller. Controller can be set to turn “ON” early a.m.
before dawn, and have Photoelectric control turn “OFF” at
dawn . . . turn back “ON” at dusk, and controller turns lights
“OFF” during nights when lighting is no longer needed.
Photoelectric control can be wired directly to 120VAC
control circuits.
MOMENTARY CONTACT
Tork Model SMC-3D
The SMC-3D will operate low voltage latching relays or
mechanically-held contactors with or without remote manual
push button override.
The adapter converts a constant applied 120VAC (input) to
a 2 second contact closure at the “ON relay” output closing
common and normally open (C, NO). When the constant
applied 120VAC input opens, a 2 second contact closure at
the “OFF relay” output between common and normally open
(C, NO) occurs. The SMC-3D can be operated by any
TORK Time Controller or a remote manual SPST standard
constant “ON-OFF” switch.
The SMC-3D will pulse “ON” an electrically-held contactor or
motor starter with self contained “ON-OFF” push buttons.
“ON” relay will pulse 2 second “ON” and electrically hold the
contactor “ON”. By interrupting the holding circuit of the
contactors “OFF” button across common and normally
closed (C, NC) of the SMC-3D “OFF” relay the 2 second
opening of common and normally closed (C, NC) will allow
the electrically held contactor to open, thereby going “OFF”.
