Digital Temperature Controller; Physical Description; Operator Settings - ABB PGC2000 Operation And Service Manual

Restoring tables and functions from E2PROM will erase any tables or functions
already residing in RAM. Since these tables and functions in E2PROM will replace
the tables already in RAM, be certain they are correct before you perform this
sequence.
If tables and functions in E2PROM are corrupted, you will not be able to restore
them. To replace the E2PROM contents, re-enter the data from the Data Sheets or
your records and then save it to E2PROM as described in "Save Tables to
E2PROM."
To restore tables from E2PROM:
1. On the Background screen, press the F1 (Exit To Commands) soft key.
2. On the Commands screen, cursor down to STORAGE & CONFIG. and then press the F2 (Save
or Restore Tables) soft key.
3. On the Table Storage screen (see Figure 4-37), cursor down to RESTORE TABLES FROM
E2PROM and then press the F2 (Restore Tables) soft key.
4. When "Are Your Sure? Y or N" appears on the screen, press the "Y" key on the GCC front panel
to confirm restoring the tables. When the GCC restores the tables to RAM, they supersede any
tables and functions already in RAM.
5. Press the F1 soft key as necessary to return to the Background screen.

DIGITAL TEMPERATURE CONTROLLER

Physical Description

The Digital Temperature Controller's temperature zones represent areas in the analyzer having
heated components: the Isothermal Oven, the Temperature Programmable Oven, the LSV, the
Methanizer, and the TCD and/or FID cells.
The Digital Temperature Controller is comprised of a DTC Backplane PCB, up to two AC Conditioning
PCBs, and up to five Temperature Zone PCBs.
The Digital Temperature Controller is set up at the factory and should not require
adjustment on site. Your application may require different setting from those
described in this manual; see the Data Package to ensure you use the correct
settings.
