close the drawer (CLS DOr). After you’ve done this you will see that the temperature is rising to the
set preheating temperature. When preheat temperature is reached the oven will beep and the status
LED’s will burn steady.
Congratulations! You just finished soldering you first PCB! You now can restart the cycle from point
1.
Changing the soldering parameters.
If you are an experience operator you know that soldering is more than just heating your product un-
til the paste is melting. For the rather inexperienced users we recommend to read about soldering
as much as you can. Ask your paste supplier for advice because the paste together with the SMD
components demand the solder heating curve and timing.
To create a good solder curve you have to set the temperatures and times from both the preheating
and the reflow process. This can be done with the push buttons E-F for preheating and G-H for re-
flow parameters. Editing the value during a soldering cycle isn’t possible. You can interrupt the sol-
dering process by opening the drawer. This will terminated the solder process!
The gap between preheat and reflow temperature cannot be set at less than 40°C. The min. preheat
set point value is 60 °C with and max. 240 °C. The timing reaches from 1 to 999 seconds.
For the reflow temperature this limits are between 100 °C and 290 °C. The time also reaches from 1
to 999 seconds.
Not all possible settings will give reasonable results. Your board will be either too cold or burned, if
you use extreme settings.
There is no standard setting available, because settings depend on both solder paste and compon-
ents. As mentioned before: ask your solder paste supplier about best practice.
If you are inexperienced and you will solder a PCB with lead free solder paste use these settings to
start from:
Use a solder paste with a melt point of 217 °C.
Pre-heat time: 300 sec. and Pre-temperature: 180 °C.
Reflow time: 70 sec. and Reflow temperature: 230 °C.
Remember! Those settings do not guarantee good results but a guideline!
Cleaning and Maintenance
Error codes:
LED C and LED D are blinking in opposite colours. An error has occurred. An Error code will be
shown in the display. Please contact your supplier and report the error code.
Err 1 = E2Prom write error
Err 2 = Error in Reflow unit, mostly one of the lamps is broken
Err 3 = Error in Preheater unit.
Err 4 = Unone thermocouple error
Err 5 = Thermocouple connected to VCC
Err 6 = Thermocouple connected GND
Err 7 = Thermocouple not connected or broken
Changing quartz lamps
The lifetime of quartz lamps is limited. After +/- 1000 hours lamps need to be replaced. Ask your
dealer for new lamps. Changing the lamps is not problematic. Remove the two screws at the top of
the door. Now open the door and replace the lamps. (See the sketch below.)
