FTR264 Series Manual ID6675 V15 5.12.2016 Firmware versions 2.0-2.
Introduction FTR264-TCK is a four-channel wireless thermocouple temperature transmitter. Typical application is temperature measurement from concrete castings. Temperature history of concrete casting can be used to calculate the development of its strength. It can also be used to produce early low temperature warnings from winter concrete castings. It is configured only for thermocouple K. FTR264 is a four-channel wireless thermocouple temperature transmitter.
Installation Dimensional drawing Dimensions in the following drawings are indicated in millimeters: Preparations It is a good idea to make an installation plan first. Write down the ID numbers of the transmitters along with their installation places or measurement target names. This will speed up the final software installation and setup of the data acquisition system. Thermocouple sensors Thermocouple sensors typically have just 2 meters of connection cable as standard.
FTR264-TCK Connecting Connect K-thermocouple sensor or thermocouple cable equipped with FMTC-K-M type connector to the cables belonging to the device. FTR264 Connecting Thermocouple factory setting is K if you want to change it see the next paragraph. Open the FTR264 lid by loosening the four plastic screws with a PH2 screwdriver. Place the lid upside down on the table so you can read the connection sticker on it. Route the sensor cables through the cable glands.
Settings Period This setting defines the transmit interval. Allowed range is 5...255 seconds. Actual transmit interval depends on, to a certain degree, the ambient temperature. Default setting is 90 seconds. This setting has direct impact on the battery life. Avoid using unnecessarily short transmit intervals as this causes shortened battery life and also limits the number of transmitters that can be used in the same coverage area.
Operation FTR264 Cable glands Cable glands should be used to route the sensor cables inside the enclosure. Only one cable should be routed through each gland. Unused glands must be plugged with supplied plugs to achieve the specified IP 65 rating. All glands must be properly tightened to ensure sealing. LED indicators Change Battery indicator blinks when the battery voltage is low and it must be changed to continue use. Sensor Fault indicator blinks when a sensor is detached or a sensor wire is broken.
Maintenance FTR264 requires no special maintenance, but the battery needs to be changed whenever the ”Change Battery” indicator starts blinking. Battery life depends on the used transmit interval. Ambient temperature also has an effect on attained battery life, temperature extremes shorten the battery life. The following diagram can be used to estimate battery life with different transmit intervals. With long transmit intervals the battery life approaches the shelf-life of the battery.
Troubleshooting None of the channels give proper readings or no readings at all. Check that the ”Data Transmit” indicator blinks once every 90 seconds (or whatever the transmit interval is). If it’s not blinking, check that the battery is properly installed and seated, and that the polarity is correct. Also ensure that the battery is not dead. Check the data acquisition system for correct settings. Verify that correct transmitter ID number is configured to the data acquisition system.
