Dtc Zone Pcb - ABB PGC2000 Operation And Service Manual

JP1 is the service diagnostics jumper. For normal operation the shunt is installed between pins 1 and
2. For service diagnostic screen use (only) the shunt is installed between pins 2 and 3. After
servicing, the shunt must be reinstalled between pins 1 and 2.
JP4 is the VAC Conditioning Board jumper. If the analyzer has one VAC Conditioning PCB installed,
the shunt should be between pins 2 and 3. If the analyzer has two VAC Conditioning PCBs installed,
the shunt should be between pins 1 and 2.
JP2, JP3, JP5, and JP6 are the jumpers for the temperature zone boards. These jumpers are
required for the software to recognize unused zones. Jumpers are installed from the even pins of
unused zones to the even pins of used zones, for both Micro #1 (JP2 and JP3) and Micro #2 (JP5
and JP6). If all zones are in use, no jumpers are installed. Zone jumpers are identified as follows:
Zone 1
Zone 2
Zone 3
Zone 4
Zone 5
Example: if Zone 5 is not used, one jumper must be run between JP2-4 and JP2-2 or one of the
other pins listed under Micro #1 Pins, and a second jumper must be run between JP6-4 and JP6-2 or
one of the other pins listed under Micro #2 Pins.

DTC Zone PCB

There can be up to five zone boards, one for each designated temperature zone. The only jumper on
a zone board is JP1 (see Figure 8-29). How this jumper is set depends on the type of temperature
sensor used for the zone. The jumper shunt should be between pins 1 and 2 for a 400 ohm platinum
probe sensor; it should be between pins 2 and 3 for a thermocouple sensor.
