14.7 Keypad Assembly Replacement
If, after consulting with the local Flowserve or factory representative, the StarPac 3’s keypad is found to be defective and
needs replacement, refer to Figure 24 and proceed as follows.
1. Make sure valve is by-passed and in a safe condition.
2. Disconnect the power and air supply to the unit.
3. Remove main housing cover.
4. Remove the two keypad retaining screws. Carefully pull the keypad away from the main PCB board. Unplug
the keypad ribbon cable from the main PCB board and remove the keypad.
5. Install the new keypad assembly by first plugging the keypad ribbon cable into the connector on the main PCB
board. Carefully place the keypad over the main PCB board.
6. Re-insert the two keypad retaining screws. Do not over-tighten.
14.8 Driver Module Assembly Replacement
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 modulator to the
main PCB assembly.
To replace the driver module assembly, refer to Figures 13, 14, 15 and 16 and proceed as outlined below. The
following tools are required:
• Flat plate or bar about 1/8” thick
• Phillips screwdriver
• 1/4” nutdriver
