OPERATION
NOTE: Slight vapor or smoke may occur in the initial heat-up. This is
the dissipation of protective coatings that have been applied to the oven
elements.
7.1 Power Supply : Connect the service cord to a grounded outlet and
push the power switch to the I/ON position. If supplied with a
detachable cordset, plug the female end into the inlet of the unit and
the male plug into the supply. Assure that units requiring a fuse have a
fuse installed. This fuse may be at the inlet or part of the cordset male
plug.
7.2 Setting Temperature: Press the upper or the lower button to rise or
lower the temperature setpoint (SV).
The new setpoint is entered when the button is released and indicated
by a brief flash of the display.
The actual temperature measured at the process (PV) is connected to
the input of the controller. This is compared with a setpoint (or
required) temperature (SP). If there is an error between the set and
measured temperature the controller calculates an output value to call
for heating. The calculation depends on the process being controlled
but normally uses a PID algorithm. The output from the controller are
connected to devices on the plant which cause the heating demand to
be adjusted which in turn is detected by the temperature sensor. This
is referred to as the control loop or closed loop control.
