Dragon 2000-1000 & 2000-1002 Manual
Bottom Heat Delivery System
The Dragon has a robust heat delivery system. A resistive element heats the air, which is driven by a maintenance-free, sealed heavy-duty brush-less motor driven blower that delivers 12.7 c.f.m. of high volume air through the heater assembly and up through the nozzle to the workpiece. The heater is a 1200 watt coil type heater that runs the length of the heater tube.
Temperature Control System
The Dragon uses a closed-loop control system for "real time" temperature measurement and control, via a type “K” thermocouple, linked to the Controller, extending along the length of the heater tube. The sensor end of the thermocouple is floating free inside the nozzle block of the machine to keep the nozzle block itself from giving the thermocouple false readings. When the machine is calibrated at the factory this thermocouple is strategically placed to ensure accurate board temperatures coinciding with the controller set point temperature.
The temperature controller used in the Dragon is an Autotune PID (Proportional Integral Derivative) digital controller, which has been Factory set to provide optimum performance in bottom heating PCBs, it is not recommended to alter the conditioning of the controller.
Dragon110Vmachines are supplied with temperature scale set to Fahrenheit. Machines of 220V are set to Celsius The Dragons close-loop control consists of a heater / blower assembly to provide heat, a thermocouple to sense the heating, and a controller to interpret the thermocouple readings controlling the demand upon the heater. Due to the high power of the Dragon heater, one is able to provide sufficient thermal energy to the process area without increasing the air temperature beyond safe ranges. The normal operating range of the Dragon Bottom Heating is from 120C to 200C.
Autotune PID Controller
1.0Overview
1.1 The Autotune is a Proportional Integral Derivative (PID) Controller, which has been Factory set in all fields to provide a linear ramp temperature profile, averaging 7 degrees a second. The ramp rate will provide an optimum bottom heat time, well within component specifications for limiting thermal stress.
1.2 To avoid complications in incorrectly altering the Factory set parameters, the Controller “LOCK” feature is enabled, however it is still possible to change Set Point temperature as necessary. To disable the “LOCK” feature, see paragraph 6.0.
1.3 The Autotune does not need to be adjusted and will accommodate all PCBs.
1.4 Although it is not necessary to change any of the configuration settings, information as to the Menus available and their defaults is listed below. We have not detailed an explanation on each PID field, as this is outside the necessary scope of operating the Dragon.
2. 0 Set Point Temperature
2.1 The most common requirement to access the Controller will be to change the Set Point Temperature. Set Point Temperature is the highest temperature that the Chipper will cycle to during the rework operation. For most applications this will be 150C but may be adjusted either up or down. Attention should be drawn to the user, that heating above the eutectic condition, of 183C, (361F) could cause bottom components to reflow.
IMPORTANT: CHECK WHETHER THE DRAGON HAS A TEMPERATURE SCALE SET IN CELSIUS OR FAHRENHEIT BEFORE CHANGING TEMPERATURE.
3.0Change of Celsius to Fahrenheit, Temperature Scale.
3.1 The Dragon is supplied with temperature measured in Fahrenheit for110V systems and Celsius for 220V systems. The Controller may be configured to the users preference by following the procedure in 7.0 (after following paragraph 6.0 “Lock” disable):
4. Menus
4.1 The Autotune Controller has three (3) levels of menus, each being accessed in ascending order, usually these Levels do not concern the user, unless it is required to disable the “Lock” feature and/or to change the temperature scale. These menus include special Tuning features and are factory set and should not be altered. Level 2, however, provides access to Temperature Scale and therefore may require access to change from Celsius to Fahrenheit, before this is carried out the “Lock” feature in Level 3 must be disabled.
4.2When reading the labels for the fields, note that Higher and Lower Case are used to describe the characters, this protocol is due to the limited ability of an eight segment display. In describing these fields below we have used Higher Case for all characters to avoid confusion.
5.0 Change of Temperature Up or Down
IMPORTANT: CHECK WHETHER THE DRAGON HAS A TEMPERATURE SCALE SET IN CELSIUS OR FAHRENHEIT BEFORE CHANGING TEMPERATURE

9.0 Menu Field Default Values
9.1 These values are detailed in order to correct any data, which may have been entered erroneously by the user. They are not meant to serve as an invitation to change any Factory set value, however should experimentation be desired, it is possible using an external Profiler, such as the APE Thermal Tracer System, which can accurately register and display the effect of the changes made. In the opinion of the manufacturer any alteration in the Factory set profile is unnecessary.
9.2 “LEVEL” 1
To access “LEVEL” 1, press keys for three (3) seconds, display will read “TUNE”, index to each field in turn by pressing key. There will be a short pause in each field to display the value:
