Page 10: Introduction
Check this information against the shipping documents to ensure the expected product and cable length are received. • The CS230 ships with a SGB3 surge protector, a 2-ft cable, 2 pan Phillips screws, and 2 grommets. Overview The CS230 temperature profiler makes use of digital sensor technology allowing for a simple 3-wire integration. -
Page 11: Specifications
The purpose of the SGB3 is to provide adequate surge protection for the CS230 Temperature Profiler. The case of the SGB3 is suited for mounting to a back plate with 1 inch on center spacing. -
Page 12: Installation
Installation Siting The CS230 is meant to be installed within the medium that is to be monitored. The types of medium that can be measured are varied, including soils, roadbeds, and water. To make the most representative measurement it is important that consistent contact be made between the temperature profiler and the medium. -
Page 13: Cs230 Installation Example
(shown in FIGURE 6-1, Internal Sensor Position #4). This information needs be addressed as part of the sensor configuration process. FIGURE 6-1. CS230 Installation Example NOTE FIGURE shows the label for the first and last internal sensor locations. -
Page 14: Mounting
While installing the CS230, the depth must be referenced between the surface of the medium and the top of the cross member of the CS230 (shown in FIGURE 6-1, Internal Sensor Position #4). If the rigid assembly is not placed at the correct depth, all measurement depths will be out of place. -
Page 15: Wiring
The lifetime minimum and maximum temperatures are used for maintenance and warranty records. Wiring Connections for the SGB3 and CS230 to Campbell Scientific dataloggers are given in TABLES and 7-2. The SGB3 is required to protect against electrical surges. -
Page 16: Long Cables
7.1.2 Power Conservation The CS230 draws less than 1 mA of current per sensor between polling sessions from its 12 V supply. In many applications this is minimal compared to overall system power use, so the sensor can be permanently powered to avoid the warm up period. - Page 17 These two characters are normally sent implicitly by Campbell Scientific dataloggers. The CS230 output is measured using a standard SDI-12 instruction to read the data from an SDI-12 sensor. For CRBasic dataloggers, the SDI12Recorder() instruction is used. For Campbell Scientific Edlog dataloggers, Instruction 105 is used.

Page 18: Sdi-12 Addressing
The CS230 comes pre-programmed with addresses from the factory. However, if ever needed, the address of temperature sensors can be changed. This may be necessary if two CS230 probes need to be placed in the same SDI-12 channel to avoid duplicate addresses on the same SDI-12 channel. -
Page 19: Slow Sequence Program Instructions
Use of the slow sequence program instructions should be considered if the CS230 measurement will exceed the program scan interval of the additional instruments included in the station. For example, if a CS230 consists of 17 or more temperature sensors, the time required to poll all sensors and receive data back can be greater than 5 seconds based on the 300 ms execution time for the aR0! command. -

Page 26: Changing The Sdi-12 Address Using Loggernet And A Datalogger
Changing the SDI-12 Address Using LoggerNet and a Datalogger It is possible to connect multiple CS230 or other SDI-12 sensors to a single datalogger control port. Each temperature sensor in the CS230, or output from another SDI-12 device must have a unique SDI-12 address (see TABLE 7-4, SDI-12 Addresses and Positions (p. -

SDI-12 transparent mode. Maintenance and Calibration The CS230 probe requires no maintenance or calibration. Troubleshooting Symptom: –9999 or NAN for temperature 1. Verify the green wire is connected to the control port specified by the SDI12 measurement instruction. - Page 28 CS230 Temperature Profiler temporarily connect the red wire to a 12V terminal (non-switched) for test purposes. Symptom: Sensor won’t respond to command Expected address not used or has been changed. Confirm all addresses in use with the aI! command to determine the individual addresses of each temperature sensor.
