MAIN WARNING
RECOMENDED GUIDELINES
RELATIVE PROFILE
It is possible to run all profiles with the Control TC plugged or unplugged.
When the Control TC is plugged, all the working modes follow the target temperatures of the selected
profile.
Once a profile has been run for the first time, it is already available in the “relative profile” mode. This
means you can run this profile without plugging the Control TC. If you place the board on the PreHeater
as the same way than you run the profile for the first time with the TC, the board will be heated identically.
To make it easier, the PH321 support has a numbered ruler and fitting parts.
Each time a profile runs completely with the plugged TC, the Relative Profile is updated.
It is possible to test a Relative profile by using the Test Relative profile within the Profile Settings menu.
MAXIMUM RAMP-UP EXCEED
The maximum ramp-up rate is set in the Station Setting Menu. The unit shows this warning if anytime
you exceed this gradient.
NO RELATIVE PROFILE. CONNECT TC
The profile should be run completely at least one time in order to be saved in the relative profile.
SECURITY TERMOCOUPLE EXCEEDED
The unit is equipped with an auxiliary TC. It is possible to set a temperature target for this TC in the Station
Settings Menu. The unit stops when the auxiliary TC reaches the target set.
INVALID PROGRAM. Error > 10ºC
This is displayed when the actual temperature differs from the setpoint by more than 10ºC for 20s.
The unit incorporates 3 default profiles which can be appropriate for most common jobs about FR4 bila-
yer substrates, multilayer and thick multilayer respectively.
1. Place the Control TC as near as possible of the component to work with.
2. If there is any sensitive component, use the Auxiliary Thermocouple as protection.
3. For repetitive jobs, you can work without TC. Once you set the appropriate profile by using the
Thermocouple, you can use the Relative Profile for the following PCBs to repair. The heating will be
always the same as long as you work with the same board on the same place and position.
4. Do not exceed the allowable heat cycles for a board or component.
5. Do not recommend to exceed ramp-up rates of more than 3-4 °C /sec
