General Purpose Oven BOGP-104

1. Description

This drying oven is used in biology, chemical pharmaceutical, medical treatment unit, industry and mining enterprise, universities and colleges and scientific research for drying, melting wax, sterilizing and disinfecting

Principle and structure

Heating tube is the back of inner chamber, fan in the back of chamber, temp. controller control the constant and change of temperature, the air flow inflows inner chamber via heating tube, and the function of fan is to make inside temperature more uniform arc-design, shelf space can be adjusted ,built in temp probe.

Wool rock as thermal insulation material between working chamber and shell, shell is made of steel plate, the shell is deal with spray paint, inner chamber is made of zinc-plating or stainless steel .the observation window is made of double tempered glass .silicone door seal to make sure better sealability, enhance the stillstand performance of inner chamber .this drying oven is equipped with intelligent temp. control system .(with timing function and precise temp. control)

3. Operation

1. The sequence of each function

The controller is powered on:

When the controller is powered on, SY is displayed on the upper monitor and the index is displayed on the lower monitor, indicating the input type. After another 2 seconds, the upper monitor shows the upper limit of the range, and the lower monitor shows the lower limit of the range, indicating the measurement range. After another 2 seconds, the upper monitor displays the measured value, and the lower monitor displays the set value, entering the standard display mode

Temperature setting:

Press the SET key to display SP in the upper monitor. Press" "or " " key to displays the lower monitor as the required value. Click the function key, the upper monitor displays ST(MIN). Press" "or " " key to displays the lower monitor as the required value. The controller returns to standard mode.

2. Detailed description of each function

Part of PV display:If " " is displayed, the sensor is short circuit or the input signal exceeds the measurement limit. If " " is displayed, the sensor short circuit or input signal is lower than the lower limit of the range. When the input signal of the controller is not within the range, the buzzer will beep, press any key can cancel it.

Query time:

When the controller works in standard mode, as long as the shift key is pressed, the upper monitor will show the timer, and the lower monitor will show the set time of the controller, then press " " key, the controller will return to standard mode.

Timing:

When ST is set to 0, the controller cancels the timing and keeps working. When ST is not set to 0, the controller has timing function. When "END" is displayed in the lower monitor, the controller stops working and the buzzer chirps, and press any key can cancel it. Press " " and " " key together for 4 seconds can restart the controller.The RUN indicator flashes when the timing function is started, and lights up when the timing function is not started.

3. Self-adjusting function(Set the setting time to 0, to cancel the timing and end the self-adjusting, then set a time again

If the temperature control effect is not good, please start the self-adjusting function. After pressing " " key for 4 seconds, the AT indicator flashes, and the controller starts self-adjusting, then the RUN indicator lights. The control effect will be greatly improved.

During the process of self-adjusting, press " " key for 4 seconds and the indicator light will turn on, the self-setting will stop, and the controller will control according to the original PID parameters.

Press the SET key for more than 4 seconds to appear LK, adjust LCK to 18, and then press the SET key to display the prompt of control parameters in the upper monitor (please see the parameter list for detailed prompts). Press " " or " " key to displays the lower row as the required value.

Press SET continuously to return to standard mode (if no key is pressed, the controller will automatically return to standard mode after one minute).
