NOTE:
When power is not supplied to the
Commissioning Tool, LEDs do not
activate. The digital display is not used,
and reads zero in this mode.
1.
To supply a resistive signal, connect Terminals
3, 4, and 5 (POT WIPER) of the OUTPUTS
terminal block to the control inputs of the
actuator or device being controlled (
Figure 6
).
Also see the appropriate actuator
documentation for wiring application
information.
Figure 6. Resistive Signal Connections.
2.
If the actuator is externally powered, skip to
Step 3.
See the
Powering a Non-externally Powered
Actuator or Control Device
section for a
procedure to apply power to the device from the
Commissioning Tool.
3.
Use the toggle switch (
Figure 7
) to select the
resistance range of 0 to 135 ohms or 0 to
1k ohms.
NOTE:
If a three-wire variable resistance is
desired, select the 0 to 1k ohm resistance
range.
4.
See the
Powering Commissioning Tool
section
for a procedure to apply power to the
Commissioning Tool.
5.
If the resistive mode green LED (
Figure 7
) does
not light, depress the SELECT MODE
pushbutton to activate the resistive mode. The
green LED should then light and indicate that
the resistive mode is active.
6.
Turn the dial (Figure 7) to adjust the level of
resistance.
Figure 7. Resistive Mode.
Proportional Voltage Mode (Vdc)
1.
To supply a 0 to 20 Vdc signal, connect
Terminals 2 (COM) and 3 (Vdc) of the OUTPUTS
terminal block to the actuator or device being
controlled (
Figure 8
). Also see the appropriate
actuator documentation for wiring application
information.
Figure 8. Voltage Signal Connections.
2.
If the actuator is externally powered, skip to
Step 3.
See the
Powering a Non-externally Powered
Actuator or Control Device
section for a
procedure to apply power to the device from the
Commissioning Tool.
3.
Use the toggle switch (
Figure 9
) to select the
OUTPUT display mode.
4.
See the
Powering Commissioning Tool
section
for a procedure to apply power to the
Commissioning Tool.
5.
Depress the SELECT MODE pushbutton to
activate the voltage mode. A green LED should
light and indicate that the voltage mode is active
(
Figure 9
).
