This controller provides sensor break protection in the event the
thermocouple opens. If an open thermocouple condition occurs, the
digital display will blink “S.br” and the power to the heating element will
be shut OFF (cycle light will extinguish).
1. Switch the circuit breaker to the “ON” position. The setpoint
temperature presently set in the controller will appear in the lower
display. The upper display indicates the actual chamber temperature.
2. To change the setpoint, press the UP or DOWN button until the
desired setpoint value is displayed, then release the button.
3. The oven will begin to heat if the new setpoint temperature is higher
than the present chamber temperature.
The controller is capable of varying temperature or process value with time
through programming. A program is stored as a series of segments and can
be run once, repeated a set number of times or run continuously. To create
a customized program using the controller parameters listed under
“Controller Parameters” at the beginning of this section, follow the
procedures outlined in the proceeding sections of this manual.
This procedure is for 4x16 Segment Programmable Models only.
The same steps are used when creating a new program and editing an
existing program with the exception being that a new program starts with
all its segments set to End in the tYPE parameter. Temporary changes can
be made to these parameters when the program is in the Hold state but
permanent changes must be made in the Reset state.
Follow the steps below to create or edit a program.
1. Press the PAGE button until you reach the program list (ProG LiSt).
2. Press the SCROLL button until display reads, “PrG.n.”
3. Press the UP or DOWN button to select a number for a new program
or to edit an existing program.
