Maintenance and Repair
8.1 Driver Module Assembly
The driver module assembly moves the spool valve by means of a
differential pressure across its diaphragm. Air is routed to the driver
module from the regulator through a flexible hose. A barbed fitting
connects the flexible hose to the driver module assembly. Wires
from the driver module assembly connect the hall effect sensor and
the piezo valve modulator to the main PCB assembly.
Driver Module Assembly Replacement
To replace the driver module assembly, refer to Figures 12-16 and 22
and proceed as outlined below. The following tools are required:
• Flat plate or bar about
1
⁄
8
” thick
• Phillips screwdriver
• 1/4” nutdriver

WARNING:
Observe precautions for handling electrostatically
sensitive devices.
