The controller will return to the HOME
DISPLAY if left idle for more than a few
seconds.
Note
Once the desired parameter has been
selected, depressing either the UP or
DOWN button will change the parameter
value. In all cases, the value shown on
the display is the current working value of
that parameter.
4x16 & 8 Segment Programmable Models with OTP
The
8 segment programmable
controller consists of
a microprocessor based three-mode PID
(Proportional, Integral, Derivative), programmable
temperature controller with over-temperature protec-
tion and appropriate output switching devices to con-
trol the furnace. The digital readout continuously dis-
plays chamber (upper display) and setpoint (lower
display) temperatures unless the SCROLL or PAGE
button is depressed. The programmable controller can
be used as a single setpoint controller or as a pro-
grammable controller. The 8 segment digital model
enables eight segments of programming.
The
4x16 segment programmable
controller con-
sists of a microprocessor based three-mode PID
(Proportional, Integral, Derivative), programmable
temperature controller with over-temperature protec-
tion and appropriate output switching devices to con-
trol the furnace. The digital readout continuously dis-
plays chamber (upper display) and setpoint (lower
display) temperatures unless the SCROLL or PAGE
button is depressed. The programmable controller can
be used as a single setpoint controller or as a pro-
grammable controller. The 4 program controller has
four 16 segment programs.
Basic Operation
When the controller is turned ON, it will perform a
short self-test and then change to the HOME DIS-
PLAY. The HOME DISPLAY shows the measured
temperature (process value) in the upper display and
the desired value (setpoint) in the lower display.
To Change the Setpoint
If you want to change the setpoint, press the UP or
DOWN button until the desired setpoint value is dis-
played in the lower display and then release the but-
ton.
