originating bay framework. Refer to wiring drawing
T-82603-31, Figure H19.
When the P716 and P1 plugs of the 847270022 wire set are
connected, the green LEDs of the AKC1B should activate,
indicating proper input power polarity to the AKC1B. If the red
LED activates, polarity into P1-1 and P1-2 has been reversed.
Reverse the Fast-on connectors of the yellow and violet wires of
the wire set on the P716 plug.
The DIP switch settings required to configure the AKC1B board
for the proper shunt size are listed in Tables 4-G and 4-H. When
the AKC1B isolator circuit is used, the DIP switch settings on
CP1 (SW109) and CP2 (SW202) must be reconfigured to
conform to these tables for the voltage and current rating of
the shunt.
For shunts that do not match the settings in Tables 4-G and 4-H,
use this recommended procedure to calibrate the AKC1B:
1. For shunts with current ratings not listed in Table 4-H, set
DIP switches to the next higher current rating.
2. For shunts with voltage ratings not listed in Table 4-G,
select the next lower voltage rating for SW1.
3. Measure plant voltage with voltmeter and record the
reading.
4. Calculate the desired reading on the ECS controller using
the following formula:
Display = (MSV/SVR) SCR
Where: MSV = Measured Shunt Voltage
SVR = Shunt Voltage Rating
SCR = Shunt Current Rating
5. Close SW2-9 and adjust potentiometer R45 (calibration)
on the AKC1B to display the load calculated in Step 4 on
the ECS ammeter.
If the expected plant load reading is not obtained through the
AKC1B, adjust the gain (R29) potentiometer of the AKC1B.
First, verify the plant shunt current and voltage ratings and use
