Getting Started Before you connect the power to this controller or install it to a control panel, please read the manual thoroughly to understand how the controller works. You should understand the following before you start using the controller: 1. Identify the correct terminals for connecting the power supply, the temperature sensor, the output to drive external solid‐state relays. 2. Understand what information will be conveyed by each of the display window and each indicator. 3. Familiar with how to change the set temperature or power percentage on the controller. 4. Familiar with how to access the menus and understand what each parameter does. ... -
Page 3: Changing The Set Value
Auber Instruments, Inc. www.auberins.com Type K: connector the positive lead to #4 and the negative lead to #5. PT1000 RTD: connect sensor leads to #4 and #5. No polarity. NTC 50Kohm thermistor: connect sensor leads to #4 and #5. No polarity. PT100 RTD: connect two wires of the same color to #4 and #5; connect the other lead to #6. The input sensor type on the controller, parameter “Sn” (Sn), must be set to match the actual sensor type that is connected. By factory default, the controller is set to ready type K thermocouple (K). Please see section 8.2 for details. 5.3. Control Output The output signal from this controller is a 12VDC signal, which can be used to drive solid‐state relays. The output status is indicated by the green OUT LED on the front panel. 6. Changing the Set Value The default Set Value (SV) is 100°F. To change the Set Value: 1. Turn the knob and a flashing dot will appear on the lower right corner of the SV window. 2. Turn the knob to clockwise to increase the SV; turn the know counter‐clockwise to decrease the SV. Once get to the desired SV, press down the knob to save the new value. Otherwise, the old SV will be restored. 3. Once the new SV is confirmed, the dot in the lower right corner will go away. 4. The SV can be changed continuously between the temperature value and the power percentage value. Please see the next section for details. 5. -
Page 4: Access The Menu
Auber Instruments, Inc. www.auberins.com Manual Control Mode When the SV is set to a percentage value, the controller works in manual control mode, which means the controller will send the power percentage determined by the user. The lower window will show letter “P” on the left to indicator the SV is a percentage value. The yellow A‐M indicator should be on. Auto Control Mode Manual Control Mode Figure 3. Compare the differences of the display on a DSPR‐5 in Auto Control Mode with the SV set at 100°F (left) and the controller in Manual Control Mode with the SV set at 100% output (right). Please see the two images in Figure 3, which show a controller in Auto Mode on the left, and a controller in Manual Mode on the right. The controller in Manual Mode has the A‐M indicator turning on and the letter “P” (P) in the lower window. To switch between Auto Mode and Manual Mode: 1. Simply turn the knob to change the SV to either a temperature (auto mode) or a percentage value (manual mode). The SV can be changed continuously from 0% to 100% to 0°F to 932°F. 2. As the SV value transits between percentage value “P 100” and temperature value “0” degree, the lower window to prompt either “TEMP” (temp) or “PCT” (Pct) briefly to indicate the new SV will be a temperature value or a percentage value. 3. When the SV is set to a percentage value, the lower window will show letter “P” on the left and the A‐M indicator will turn on. 4. When the SV is set to a temperature value, the lower window will only show a number and the A‐M indicator will turn off. 8. Access the Menu Press down the knob and hold it for 2 seconds to bring up the menu. The top window will show “go to” (GOTO). Turn the knob to change the lower window to “CTRL” (CTRL) or “SYST” (SYST), then press ... - Page 5 Auber Instruments, Inc. www.auberins.com 8.1. Control Configuration (CTRL) Table 1.
