Digital outputs are provided for check-

weighing and filling applications where

the I150 will be used to control other

devices. Refer to “Checkweighing” and

“Filling and Emptying Processes” in the

OPERATION section of this manual for

instructions on using these features.

The digital outputs are accessed via a 4-

pin header which is located on the compo-

nent side of the display circuit board (see

diagram).

Use the setpoint connector provided in

the accessory kit, and a suitable cable for

connecting to the header. The cable must

be round to fit properly through one of the

liquid tight connectors.

1. Locate the 4-pin header on the dis-

play circuit board.

2. Pass the cable through any free liq-

uid tight connector.

3. Connect the cable wires to the socket

connector according to the pin con-

nections shown in the table.

4. Plug the setpoint connector into the

4-pin header on the display circuit

board. Make sure the connector is

properly oriented.

5. Tighten the seal bushing until resis-

tance is felt against the cable.
