DATAP R O-45™
If readings close to 30°F appear, then there is very likely an accidental reversal of wires somewhere. Check all connections between the actual probe and the junction box.
Midrange Temperature Sensors (T9-T16)
The last eight temperature inputs on your DATAPRO-45™, T9 through T16, are designed for use with type K thermocouple probes measuring fluid and ambient air temperatures. These channels have a maximum reading capability of approximately 482°F. Special type K extension cables must be used, without exception. The cable may be shortened if required. Cut the cable to the desired length (plus some spare) and carefully cut the stainless steel overbraid back approximately 1”. Shrink tubing should be used over the cable where it exits the connector to make for a neater installation. Make certain that the overbraid in no way comes in contact with the wire terminals in the connector. Strip the YELLOW wire back approximately _” and connect to the plus (+) terminal in the connector such as D5. Repeat the process for the RED wire and connect to the negative (-) terminal such as D6. NOTE: Only this wire can be utilized. Substitution of a different wire will affect the operation of the sensor. REMEMBER - The RED wire must be connected to the MINUS (-) terminal and the YELLOW wire must be connected to the POSITIVE (+) terminal.
TESTING: Change the LCD display channel to the appropriate channel, such as “Temp 9.” An appropriate temperature should be seen. Note that an error as large as 5°F may be present. This is especially evident when trying to read temperatures close to ambient (room temperature). This is because thermocouple technology is not designed for accurate readings at these levels. The readings will be repeatable from run to run, but not any more accurate. These inputs are really intended for reading things such as oil or water temperature, which are typically higher. If you need more accurate readings of room temperature values, such as intake air temperature, consult with Computech for an alternative temperature sensor.
If readings close to 30°F appear, then there is very likely an accidental reversal of wires somewhere. Check all connections between the actual sensor and the junction box.
Your DATAPRO-45™ can drive up to four sequential shift lights, or it will light one light up to 4 times. See your DATAPRO ON-LINE™ software for configuring the shift point for each light.
