CRYOGENICS
Once a Cryopump which is contained within a roughing map has started
FastRegen, no other Cryopump in that map can start a FastRegen until that
pump reaches 115K in cooldown. Full regenerations can be started
individually or in groups at any time. If a FastRegen is currently in
progress, then the pump in Full regeneration will not be roughed out until
the FastRegen pump is below 115K in cooldown.
Establishing Roughing Maps and Password Protection
1. Press the SERVICE key.
2. Press 9 9 (this allows access to the local service function of the
Terminal itself rather than a pump). The serial number and the
software version of the Terminal will be displayed.
NOTE: The TERMINAL ID #XX in step 3 is present if the NetLink option is
installed.
3. Press Next to display TERMINAL ID #XX.
4. Press Next to scan the network and to display the number of pumps
on the network (up to 20 pumps).
5. Press Next to display a password request.
6. Enter a password (if being used); then press Enter and Next. Press
0 if a password is not being used.
NOTE: When operating pumps from a Network Terminal, a common
password can only be entered from within the local service of the Network
Terminal. All password changes must also be made from this location. If a
password is entered at a pump, the Network Terminal will override that
password and default it back to the password set at the Network Terminal.
The display reads REGEN LOCK OFF. 1 will turn on lock mode; 0 will
turn off lock mode. When lock mode of the Network Terminal is activated,
it will lock you out of the regeneration group function.
7. Press Next. The display reads ROUGH VALVE MAP.
8. Press Enter. The display reads MAP A and shows which pumps, if
any, are currently in that map. You may have to press the right scroll
arrow > to move the display so that all pumps in that map can be
seen.
9. To change the map, press Enter. All pumps in MAP A are removed
and a new program can be entered into MAP A.
10. Enter the 2-digit number of one of the pumps you want in MAP A.
11. Press Enter to accept that pump number, or press Clear to remove
that number.
