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

CONFIGURATION
1) Select the desired measurement range (see step 3
2) Select the desired measurement mode (see step 4)
3) Con gure the relay (optional) (see step 5)
The device is now ready to use.
SEL. THE MEASUREMENT RANGE
Select the measurement range by installing jumpers as shown in
Figure Z. (See Figure 3a-3b – Jumper settings)
Range 10 (0-2000 fpm)

SEL. THE MEASUREMENT MODE
Con gure 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 con gured separately.
