We thank you for the confidence you have shown by purchasing the Weller Heating Plate WHP 3000. During manufacture the strictest quality requirements are applied; these assure the correct function of the device and make it possible to obtain optimal soldering results.

Attention
Prior to placing the device in operation, please carefully read these operating instructions and the safety instructions enclosed. If the safety instructions are not observed, there is a risk of injury. The manufacturer accepts no liability for usage other than that described in the operating instructions or for unauthorized modifications The WELLER heating plate WHP 3000 complies with the EU declaration of conformity as per the essential safety requirements in the directives 89/336/EEC and 73/23/EEC

Description

The WHP 3000 heating plate is equipped with 3 infrared high-temperature lamps and enables electronic assemblies to be pre-heated in numerous ways. The high- temperature lamps emit radiation primarily in the wavelength range of 2 – 10 μm and heat modern materials rapidly and efficiently. Digital regulation electronics ensure precise temperature behavior and support various special functions such as “AUTO OFF” or standby temperature. Setpoints and actual values are indicated digitally. Two different size heating zones are available. Using an optional external sensor, the temperature can be regulated at defined measuring points. An integrated RS232 interface enables the device to be controlled externally from the Weller WHA 3000P/V hot air station. Here is the WHP 3000 the heating plate is used as a bottom heater in a 3-step temperature-time profile.

Temperature range: 50°C – 400°C (150°F – 750°F)
Protection class : 1

Placing in operation

Remove all temperature-sensitive and flammable objects from the vicinity of the heating plate. Ensure that the heating plate is switched off. Ensure that the mains voltage is correct. Connect the device to the mains (12). Switch on the device at the main switch (6). When the device is switched on, a self-test is performed during which all display elements (4) are operated. The temperature set (setpoint) and the temperature scale (°C / °F) are then displayed briefly. The display then switches automatically to the indication of the actual value. The red dot on the display illuminates (8). This dot is a visual indication of the state of the regulation. Continuous illumination indicates the system is warming up. Flashing indicates that the operating temperature has been reached.

Adjusting temperature
The digital display (4) normally indicates the actual temperature. The digital display (4) switches to the current setpoint when the ”UP” or “Down” button (5)(7) is pressed. The setpoint (flashing indication) can now be changed as required by pressing or pressing and holding the “Up” or “Down” button (5)(7). If the button is pressed and held down, the setpoint changes quickly. Approx. 2 sec. after the button is released, the digital display (4) automatically switches back to the actual value.

Switching over between large/small heating zone
Two different power settings and sizes of the active heating surface are available. Switchover is performed by pressing the HIGH POWER button (9).

Small heating zone : 120 (4.72) x 60 (2.36) mm (inch) / 200 W (center lamp active)
Large heating zone: 120 (4.72) x 185 (7.28) mm (inch)/ 600 W (all lamps active) HIGH POWER LED (2) illuminates

Note
The heating zone should be selected prior to use (when the device is cold). Switching over from the small to the large heating zone when the device has reached a steady-state temperature will result in long warm-up times for the additional lamps.

Manual heating shut down (OFF)
The device heating is shut down by simultaneously pressing the “UP” and “DOWN” buttons. “Off” appears on the display (4). If the standby function is also active, the temperature is reduced to 100°C (212°F). “Stb” appears on the display (4).

Automatic heating shut down (AUTO OFF function)
The auto-off time for the heating shut down is displayed flashing by pressing and holding (approx. 3 sec.) the HIGH POWER button (2). The shut-down time can be adjusted in 5-minute steps in the range of 5 – 600 min by pressing the “UP” or “DOWN” button (5)(7). A setting of less than 5 min switches off the automatic heating shut-down and “OFF” appears on the display (4). If the standby function is also active, the temperature is reduced to 100°C (212°F). “Stb” appears
on the display (4).

Operation using RS232 serial interface
When operated together with the WHA 3000P/V hot air station, the WHP 3000 heating plate is controlled via the RS232 serial interface (11). Here the heating plate is used as a bottom heater for electronic assemblies and is integrated into a
3-step temperature-time profile. When used in automatic mode (Remote LED (1) illuminated) it is not possible to make any entries directly at the heating plate. Only the switchover between the heating zones (9) remains active. The temperature setting is made via the WHA 3000P/V hot air station. When the program is not active, the heating plate is switched off. “OFF” appears on the display(4). If the standby function is also active, the temperature is reduced to 100°C (212°F). “Stb” appears on the display (4).

STANDBY function
In standby mode, the temperature is reduced to 100°C (212°F) if a heating shut-down occurs (using OFF, AUTO OFF, RS232). The standby mode is activated via a “Power-On Routine”. For this purpose, the device is first switched off at the main switch (6). Press the HIGH POWER button (9) and switch on the device. Keep the button pressed until the – 1 – appears on the display (4). When the “HIGH POWER” button is released the setting is saved. The standby function is switched on. Use the same procedure for switching off. – 0 – appears on the display (4) (factory setting).

OPERATION WITH EXTERNAL SENSOR

It is also possible to measure the control variable for temperature regulation using an external sensor. If an external sensor is connected, the current temperature from the external sensor is displayed and controlled instead of the temperature of the heating lamps. The external sensor, an insulated thermocouple type K, is connected to a socket (10). LED (3) on the display (4) illuminates.

Note
The sensor must be adequately in contact with the assembly or component for correct operation. When working with the external sensor, the temperature setting (setpoint) must be adjusted to suit the measuring point.

Error indications on the display (4)

– – – No temperature sensor detected
E10 Maximum housing temperature exceeded

Other power-on routines (°C / °F ; FSE)

°C / °F change over
For this purpose, the device is first switched off at the main switch (6). Press the DOWN button (7) and switch on the device. Keep the button pressed until the “°F” appears on the display (4). When the “DOWN” button is released the setting is saved. Use the same procedure for the change over to “°C”.

Resetting to the factory setting (FSE)
For this purpose, the device is first switched off at the main switch (6). Press the “UP” (5) + “DOWN” (7) + “HIGH POWER” (9) button simultaneously and switch on the device. Keep buttons (5, 7, 9) pressed until “FSE” appears on the display (4). When the buttons (5, 7, 9) are released the setting is saved.
