Weller WHP 3000 - Manual (Page 17)

12
We thank 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 unauthori-
sed modifications
The WELLER heating plate WHP 3000 complies with the EU
declaration of conformity as per the essential safety require-
ments in the directives 89/336/EEC and 73/23/EEC
1. 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 2 - 10 µm
and heat modern materials rapidly and efficiently. Digital
regulation electronics ensure precise temperature behaviour
and support various special functions such as “AUTO OFF” or
standby temperature. Setpoints and actual values are indi-
cated 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 the WHP 3000
heating plate is used as a bottom heater in a 3-step tempe-
rature-time profile.
Technical data

2. 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 cor-
rect. Connect the device to the mains (12). Switch on the
device at the mains 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 tem-
perature 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.
2.1. Adjusting temperature
The digital display (4) normally indicates the actual tempe-
rature. The digital display (4) switches to the current setpo-
int when the ”UP” or “Down” button (5)(7) is pressed. The
setpoint (flashing indication) can now be changed as requi-
red by pressing or pressing and holding the “Up” or “Down”
button (5)(7). If the button is pressed and held down, the set-
point changes quickly. Approx. 2 sec. after the button is rele-
ased, the digital display (4) automatically switches back to
the actual value.
2.2. Switching over between large / small heating zone
Two different power settings and sizes of the active heating
surface are available. Switch over is performed by pressing
the HIGH POWER button (9).
Small heating zone:
120 (4.72) x 60 (2.36) mm (inch) /
200 W
(centre 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). Switch over from the small to the
large heating zone when the device has reached a stea-
dy-state temperature will result in long warm up times
for the additional lamps.
2.3. 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).
2.4. Automatic heating shut down (AUTO OFF function)
The auto off time for the heating shut down is displayed flas-
hing 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 5 - 600 min by pressing the “UP”
or “DOWN” button (5)(7). A setting of less than 5 min swit-
ches off the automatic heating shut-down and "OFF" appe-
ars on the display (4). If the standby function is also active,
