the temperature is reduced to 100°C (212°F). “Stb” appears
on the display (4).
2.5. Operation using RS232 serial interface
When operated together with the WHA 3000P/V hot air sta-
tion, the WHP 3000 heating plate is controlled via the RS232
serial interface (11). Here the heating plate is used as a bot-
tom 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 switch over
between the heating zones (9) remains active. The tempera-
ture 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).
2.6. 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 mains switch (6). Press the HIGH POWER button (9) and
switch on the device. Keep 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 swit-
ched on. Use the same procedure for switching off. - 0 -
appears on the display (4) (factory setting).
3. OPERATION WITH EXTERNAL
SENSOR
It is also possible to measure the control variable for the tem-
perature regulation using an external sensor. If an external
sensor is connected, the current temperature from the exter-
nal sensor is displayed and controlled instead of the tempe-
rature of the heating lamps. The external sensor, an insula-
ted thermocouple type K, is connected to 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 set-
ting (setpoint) must be adjusted to suit the measuring
point.
4. Error indications on the display (4)
- - - No temperature sensor detected
E10 Maximum housing temperature exceeded
5. Other power-on routines
(°C / °F ; FSE)
°C / °F change over
For this purpose the device is first switched off at the mains
switch (6). Press DOWN button (7) and switch on the device.
Keep 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 mains
switch (6). Press “UP” (5) + “DOWN” (7) + “HIGH POWER” (9)
button simultaneously and switch on the device. Keep but-
tons (5, 7, 9) pressed until "FSE" appears on the display (4).
When the buttons (5, 7, 9) are released the setting is saved.
