are analog (typically pressure).

Sensor Name Used to label a particular sensor. This information is not stored in the Channel and is

used for messaging to the user only.

Calibration Number Calibration number of the sensor. This is typically found on the sensor and the units

are displayed in the help text on the console. For NH3 applications, refer to APPEN-

DIX C - NH3 APPLICATION.

Cal# Basis Table of preset calibration numbers. Used to rapidly change calibration number nozzle

constants on pressure based liquid machines, or for saving multiple calibration num-

bers for different Injection Pump tubes, or for creating a table of calibration numbers

for use on a spreader with an adjustable gate height. Refer to APPENDIX B - CREAT-

ING CALIBRATION TABLE.

Nozzle Constant Used for applications where a pressure sensor is being used as the primary sensor.

Enter the gal/acre rating of nozzles being used at 10mph and 30psi (10 km/h - 2 bar

for metric applications) regardless of the actual speed and pressure at which the

machine will be operated.

SECONDARY SENSOR

NOTE: Secondary sensors are only used on machines that have a second sen-

sor that may be used for feedback and control of the product (e.g., a

spreader with two feed chains with a sensor on each chain). If you are

unsure about the use of the Secondary Sensor, please contact your local

TeeJet Technologies supplier for direction.

Secondary Sensor types are based on the Application and Primary Sensor types

that were selected. Each Secondary Sensor Type has a Settings softkey that

launches the Secondary Sensor Settings page. The parameters depend on the

type of Primary Sensor selected. Each Channel has six input sensors labeled A

through F. Sensor inputs A-D are digital (frequency) and sensor inputs E and F are

analog. The sensor input cables on the DCM Product harness are labeled A-F. The
