Operation

Power Switch

The power switch has two positions, “ON and “STANDBY.”

ON STANDBY

The fans are activated whenever the unit is plugged into a live power outlet. Regardless of whether the power switch is on, the fans will run for a period of 2 hours or until the power is turned on. The fans will remain on as long as the unit is turned on. Once the unit is switched from “ON” mode to “STANDBY” mode

the fans will again run for 2 hours. Never disconnect the power cord

while the unit is still cooling down. A safety hazard may result and the unit may get damaged.

Temperature Controller:

The controller is used for setting the desired temperature of the cavity. The controller display provides process temperature and setpoint temperature. A 4 button keypad is used to set the setpoint temperature and change engineering units.

Temperature Reference Meter:

The temperature reference meter displays the cavity temperature with high precision. See Section 3.5 for parameter programming information.

3.2 Heater Cavity and Aperture Plate

The heater cavity is a near ideal blackbody source. The emissivity of the cavity is 0.99. When calibrating an IR pyrometer, hold the pyrometer perpendicular to the aperture for optimal performance. The proper distance between the IR pyrometer and the target plate depends on the field of view of the pyrometer. If the pyrometer is too far away, it will scan unwanted surfaces outside of the perimeter of the target plate. Holding the pyrometer too close could introduce undesirable heat to the IR detector of the pyrometer. Always aim the gun toward the center of the cavity cone. Then search for the hottest spot. Use the pyrometer’s peak detector feature.

The layout of the front panel is shown in Figure 2. The BB705 incorporates a PID digital temperature controller. In the default mode, the digital displays the process variable (PV) as well as the setpoint variable (SV). The process variable in the BB705 is the current measured temperature of the heater cavity. The

3-5

Page 14

Operations

setpoint variable is the desired temperature the user has set. Setpoint temperature can be changed by depressing the “

” and “ ” keys. Holding either of these keys for an extended period will cause the setpoint temperature to advance more quickly to a desired value. Three scanning speeds are provided: slow, medium and fast. The minimum and maximum setpoints are locked at 0 and 1046°C (32 and 1915°F), respectively. While these max. and min. settings

are changeable (see “Changing Controller Parameter Settings,” Section 3.4.2), it is strongly advised not to adjust these parameters.

NOTE:

P.I.D. Control: Proportional, integral, derivative control ( P.I.D.) is a temperature control algorithm used in high-end temperature controllers. The controller causes the process to attain the desired temperature by turning the process on or off. The process may be a heater or refrigerator. As the process temperature approaches the setpoint temperature the hot or cold process will be pulsed to reduce the corrective measures and minimize overshooting. The controller provides a visual representation of the process status through LED indicators. An indicator may be lit continuously, blink or shut off entirely to indicate that the process is on, being pulsed, or off, respectively.

3.4.2 Changing the Controller Parameter Settings

The BB705’s controller operates at its optimum performance when left with the factory parameter settings. The only internal parameter that the operator may need to change is the engineering units (°C or °F) or serial communications parameters. If the parameter settings are accidentally altered or become lost, the parameters should be re-programmed in according to the factory default settings. Below are two diagrams: a) menu hierarchy with factory default settings b) programming procedure.

Section 4 - RS232 Communications

The controller and reference meter provides for bi-directional data transfer via a three conductor cable consisting of signal ground, receive input, and transmit output. It is recommended that less than fifty feet of shielded cable be used

between the computer and this instrument. This will assure performance of the BB705 to EN61326 standards, under the E.M.C. Note that multiple

instruments cannot be tied to the same port in this configuration. The RS232 port is optically isolated to eliminate ground loop problems.

In Figure 9 is a pinout diagram for the serial port of the BB705 as well as the pinout for a 9-pin PC serial port. Use a straight DB9 (female) to DB9 (male) connector cable to connect your computer to the BB705. The cable should be attached only when the computer and BB705 are off.

Only parameters in the parameter list should be modified or queried via the serial port. Other parameters should be viewed or queried from the controller, directly. It is highly recommended that baud rate for the controller be modified on the controller, directly. Note that both the BB705 and the computer must be communicating with the same serial communications parameters to establish a working communication link.

RS232 Communications

The serial communications feature can be tested using terminal emulation package. Note that this controller does not time out waiting for the next character to be transmitted. Be sure not to use the XON/XOFF or hardware handshaking. Lastly, it should be noted that following a complete transmission to the BB705, a response it sent back. If the message was valid, the changed or queried parameter is echoed back (following the same format). If the message was not according to acceptable format or was attempting to force a parameter out of range, an “ERROR” message is echoed.
