INSTALLATION (Continued)

Wiring

The 4-20mA module comes pre-wired for external connections to external power and

provides an open collector output, which can be set to either raw or scaled pulse output. The

wires are color coded to connect as shown in Figures 3 & 4.

Uninsulated

NOTE: The 4-20mA board provides a pulse output on the White wire with the cable shield

as the ground (return). This is set to raw pulse output as the default setting on the Q9 display.

If your application requires a scaling of the pulse output, refer to the installation instructions

to enable the scaled pulse feature and refer to the Q9 owner's manual for instructions on the

configuration of the scaled pulse feature.

NOTE: If using the scaled pulse output feature, use the scaled K-factor in the user interface

device.

NOTE: The ground of the pulse output must be galvanically isolated from the 4-20mA loop

ground (return).
