Module Replacement
P/N 8040406
The serial numbers of the On-Board Cryopump and On-Board Module
must match to ensure module/pump calibration. Refer to Appendix A and
be prepared to provide the CTI-CRYOGENICS Service Representative
with the following information when requesting a replacement On-Board
Module:
•
Pump Serial Number
•
On-Board Module Part Number and Serial Number
•
Number of Hours on Pump
CTI-CRYOGENICS will ensure that the existing module serial number is
programmed into the replacement module to maintain the calibration
integrity of the On-Board System.
NOTE: The existing On-Board Module may be programmed to specific
user defined process parameters. The replacement module must be pro-
grammed to restore the user defined parameters once installed.
1. Set the On-Board power switch located on the compressor or
compressor controller to the OFF position.
2. Remove all cables from the Power In, AUX TC, Remote, Relays,
Network, and RS-232 connectors as shown in Figure 4-1.
3. Using a straight blade screwdriver, loosen the safety interlock
screw until the On-Board Module is released from the module
housing. Slide the On-Board Module out of the housing.
NOTE: Make sure the safety interlock screw is completely tightened during
step 4 to ensure that the module circuit board is inserted into the housing
connector.
4. Insert the new On-Board Module into the module housing and
tighten the safety interlock screw.
