Figure 6. Instrument Assembly Details
Direct or Reverse Action
Direct action means, when looking at the slotted end
of the potentiometer shaft, a clockwise rotation of the
shaft produces an increasing output signal from the
transmitter.
Reverse action means, when looking at the slotted
end of the potentiometer shaft, a clockwise rotation
of the shaft produces a decreasing output signal
from the transmitter.
The transmitter produces a direct or reverse action
output signal depending on the location of the
potentiometer wires inserted in terminal block
number 1 (TB1) mounted on the transmitter printed
wiring board. Refer to figure 6 for the location of the
wires and the wire color sequence for direct action.
For reverse action, exchange the positions of the
brown and red wires.
