CONTROL PANEL OVERVIEW

 

 

5.1 

Power  Switch:

    The  main  power  switch  on  the  control  panel  (green  lighted  I/O) 

controls all power to the oven.  It must be in the I/On position before any systems 
are operational.  The green pilot light in the switch will be lighted when the switch is 
in the ON position. 

5.2 

Timer Switch:

  The black I/O power switch marked TIMER is located to the right 

of  the  main  power  switch.    It  controls  the  power  to  the  time  circuit.    In  the  O/Off 
position  the  oven  heat  is  controlled  with  no  timed  duration.    In  the  I/On  position 
heat is controlled for a timed interval and then the heat shuts off. 

5.3 

Overtemperature Limit Thermostat:

  This control is marked HIGH LIMIT and is 

equipped  with  an  adjustment  knob  and  a  graduated  dial  from  0  -  10.    It  is 
independent  of  the  Main  Controller  and  guards  against  failure  which  would  allow 
temperature  to  rise  past  the  Main  Controllers  set  point.    This  allows  continued 
operation  of  the  oven  until  the  problem  can  be  corrected  or  service  can  be 
arranged. It is not recommended that the unit be operated for extended periods of 
time  using  only  the  Overtemperature  Safety  as  the  temperature  controller  as 
temperature uniformity will suffer. 

5.4 

OTP  Light:

    This  pilot  lamp  is  directly  above  the  Overtemperature  Limit 

Thermostat.    The  light  will  come  on  when  the  Safety  Thermostat  has  been 
activated  and  taken  control  of  the  oven.  Under  normal  operating  conditions  the 
pilot lamp should never be on. 

5.5 

Timer  Control:

    This  control  is  marked  SET/TIMER  and  consists  of  a  digital 

display, UP/DOWN arrow pads, a RESET "PUSH" pad, a START/STOP "PUSH" 
pad  and  a  TIMER  ACTIVATED  light.    This  control  provides  the  ability  to  set  a 
timed heat interval, activate the start-up of the timed heat cycle and shut down the 
timed heat cycle automatically. 

5.6 

Main Temperature Controller:

  This control is marked SET/TEMPERATURE and 

consists of the digital display and UP/DOWN arrow pads for inputting set point 
temperatures and calibration.
