8 Segment & 4x16 Segment
Section 6
Programmable Models
The 8 segment programmable controller consists of a microprocessor
based three-mode PID (Proportional, Integral, Derivative), programmable
temperature controller with over-temperature protection and appropriate
output switching devices to control the oven. The digital readout
continuously displays 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
programmable controller. The 8 segment digital model enables eight
segments of programming.
The 4x16 segment programmable controller consists of a microprocessor
based three-mode PID (Proportional, Integral, Derivative), programmable
temperature controller with over-temperature protection and appropriate
output switching devices to control the oven. The digital readout
continuously displays 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
programmable controller. The 4 program controller has four 16 segment
programs.
Note 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 display is the current working value of that parameter.
