Thermistor Tcd Amplifier Interface Pcb - ABB PGC2000 Operation And Service Manual

The carrier jumper is normally connected between WT9 and WT10 (single carrier). For dual carrier
applications this jumper is connected between WT7 and WT8.
The temperature jumpers are normally connected between WT1 and WT2 and between WT4 and
WT5 (low temperature). For high temperature applications these jumpers are connected between
WT1 and WT3 and between WT4 and WT6.
For normal operation shunts should be installed in the first two positions at the right side of J18.
These shunts are removed for an application using intercolumn detectors.
The jumper between WT14 and WT15 must be in place for normal operation. It is only removed
when hi-pot testing is to be performed.

Thermistor TCD Amplifier Interface PCB

The Thermistor Amplifier Interface PCB currently supports one or two Thermistor Amplifier PCBs (see
Figure 8-34).
Figure 8-34. THERMISTOR AMPLIFIER INTERFACE PCB JUMPER LOCATIONS
For single detector applications, one Thermistor Amplifier PCB is used, mounted in the Amplifier #1
position. Jumpers JP-1, JP-2, JP-1A and JP-2A all have their shunts between terminals 1 and 2.
The output signal is routed through J13A.
For dual detector applications, two Thermistor Amplifier PCBs are used, mounted in the Amplifier #1
and Amplifier #2 positions. Jumpers JP-1, JP-2 and JP-2A all have their shunts between terminals 1
and 2. Jumper JP-1A has its shunt between terminals 2 and 3. The output signal of Amplifier #1 is
routed through J13A and the output signal of Amplifier #2 is routed through J13B.
