DOOR LOCK CONTROL / TIMER
VDSC305-VDSC365-
VDSC485(RH)
VDSC485(LH)-VESC305-
VESO105 VEDO205
Function: The Door Lock Control / Timer is
activated by the line voltage at the “ SEL”
( 1 ) contact. Relay “ RL1" ( 2 ) and “RL2"
( 3 ) close providing voltage to the Door Lock
Motor. The Relays stay closed until 10
seconds after sensor #3 ( 4 ) receives a signal
that the Door Lock is fully closed. Once this
happens Relay “RL2" ( 3 ) opens to stop the
Door Lock Motor. Relay “RL1" ( 1 ) stays
closed providing voltage to the Auto Reset
thermostat. Relays “RL3" and “RL4" close
powering the Cooling Fan Motor and Cycle
Relay. “RL3" and “RL4" will stay closed for
3 ½ hours unless power is interrupted to
sensor #3 ( 4 ) or SEL ( 1 ). In which case
“RL3" and “RL4" will open, interrupting the
clean cycle and Cooling Fan, and “RL2" ( 3 )
will close, opening the Door Lock. “RL2" ( 3)
will stay closed until 2 seconds after sensor
# 4 ( 5 ) is powered.
AUTO RESET SWITCH
VDSC305-VDSC365-VDSC485(RH)-
VDSC485(LH)-VESC305-VESO105-VEDO205
Function: The Auto Reset Switch is a single
pole / double throw switch ( thermostat )
which is activated by a thermo-bulb and lever
which is calibrated to 575* F plus / minus 25*
F. Clean door lock below 575* F. The Door
Lock Motor is energized through the Auto
Reset Switch ( thermostat ) contacts 2 - 1.
Clean door lock above 575* F. Auto Reset
Switch (thermostat ) switches to contacts 1 -3
turning on the Door Lock indicator Light and
disables the Door Lock Motor circuit. Final
below 575* F. Auto Reset Switch (
thermostat ) switches to contacts 1 -2, turning
off the Door Lock Motor circuit through door
Lock Motor / Timer Relay LS2 - M1. Door
Lock Motor operates until 2 seconds after
sensor 4 is signaled by VC that the Door Lock
switch SW1 has been closed mechanically by
the door lock bolt. The Door Lock / Timer
switches LS2 - M1 and LS1-L1 open and the timer
