Replacing the Temperature Controller PCB
36 EASY-Spray Series Ion Source User Guide
If the temperature controller PCB becomes damaged, the actual temperature display might
remain off and the EASY-Spray column might not heat. Follow this procedure to install a new
PCB.
 To replace the temperature controller PCB
1. Follow the procedure
CAUTION High voltage. To prevent electric shock, make sure that you disconnect the
P-Bus cable before you remove the PCB.
2. Using a 2.5 mm hex key, remove the four hex screws located on the bottom of the ion
source. If you previously installed the temperature controller PCB, P/N ES233, in the
EASY-Spray source, remove the additional cover plate
Note The cover plate is for use on the EASY-Spray ion source (ES081) only when
installing the ES233 temperature controller PCB.

and extra cover plate
3. Slowly pull out the enclosure for the temperature controller PCB
IMPORTANT If you remove the temperature controller PCB too quickly or at an
angle, you might damage the PCB components or the internal heater cable routed
above the PCB.
