HK Instruments AVT Series Installation Instructions page 3

STEP 2: WIRING DIAGRAMS
For CE compliance a properly grounded shielding cable is
required.
1) Unscrew the strain relief and route the cable(s). Use the strain
relief on the left for power in and signal out (Tout/vout) and the
strain relief on the right for relay.
2) Connect the wires as shown in figure 2a and 2b.
3) Tighten the strain relief.

CONFIGURATION
Configuration requires:
1) Selecting the desired measurement mode, step 3.
2) Selecting the desired measurement range, step 4.
3) Configuring the relay (optional), steps 5 and 6.
Selection convention used to input configuration
information into AVT transmitter.
Entering the configuration information into the AVT transmitter
is accomplished with the joystick, the display, and the jumpers
installed and removed from the set of three (3) or four (4) jumper
pins, see Figure 3 and schematics.
Joystick Pressing down or tilting (tilt up/down or side-to-
side) will cycle the display though the available
menu choices. The joystick will only cycle the
choices up. If you accidently pass your preferred
selection continue to activate the joystick until
your selection reappears.
Jumpers Jumpers are used in two (2) different ways:
1. Jumpers are installed, and remain installed, to
select the required choice, see Steps 3 and 4.
2. Jumpers are installed, a choice is made, and
the jumper is removed, see Steps 5 and 6.

STEP 3: SELECTING THE MEASUREMENT MODE
Configure the outputs:
• Temperature output (Tout)
• Velocity output (vout)
Select the output mode, current (mA) or voltage (V), by installing
jumpers as shown in Figure 4. Both outputs, temperature (T) and
velocity (V), are configured separately.
T Temperature output (Tout): T = voltage (V)

Velocity output (vout): v = voltage (V)

STEP 4: SELECTING THE MEASUREMENT RANGE
Select the measurement range by installing jumpers as shown in
Figure 5. (Note: Figure 3, Jumper installation)
Range 2 (0–400 fpm) (0–2 m/s)
Range 10 (0–2000 FPM) (0–10 m/s)
Range 20 (0–4000 FPM) (0–20 m/s)
