    E-mail: salesinst@dynisco.com NTRODUCTION The TX180 is a transmitter that accommodates any one of eleven types of thermocouples, six types of RTD’s, millivolt or ohm inputs. The unit is precision linearized to the measured temperature over the entire usable range of the selected sensor. This transmitter is simple to set up and operates much like high performance analog transmitters.

    These housings have appropriate mounting means in the bottom to attach the TX180 in any of four orientations 90° apart. Captive 8-32 machine screws are installed on the transmitter to facilitate installation and removal to either a housing...

  • Page 7: Mounting

    2.2.2 M OUNTING The TX180 transmitter may be mounted on a 2 inch pipe (vertical or horizontal), on a bulkhead, a panel, a DIN rail or other rigid support members utilizing the various mounting brackets and associated hardware available from Dynsico. These types of mounts provide greater flexibility in installation and removal of transmitter for service.

    LECTRICAL NSTALLATION The TX180 has two groups of terminals. One terminal group is for the sensor input. The second terminal group is for transmitter output. The terminals labeled “+” and “-” are the 4 to 20mA output terminals. These are normally connected to the corresponding polarity terminals of the power supply of the current loop.

    250 ohm resistor. Now turn on the power supply. In about 5 seconds the TX180 loop current will settle to its normal value in the range of 4 to 20mA, unless the input terminals are open, in which case the output current will be 23.00mA.

  • Page 14: Configuration Using The Two-Line Display

    To configure a transmitter using the DISPLAY MODE, either the LI-1 or LI-2 local LCD display is required. These displays are available as an option and can be plugged into the top of the TX180 transmitter. The transmitter can also be purchased with these options already installed. These inexpensive options make the reconfiguration, or re-ranging of the transmitter very simple and easy to follow.

  • Page 15: Display Mode Configuration

    TX180 Temperature Transmitter The transmitter is indicating FAILSAFE, since no sensor is connected, and the analog output is indicating greater than 100%, loop current at 23.00mA, which is the standard Failsafe report condition. Please note that the display / keyboards can be plugged into the transmitter while the transmitter is powered up.

    TRIM 4 MA? This allows trimming of the 4.00mA output current. NOTE: This function is only for the purpose of adjusting the 4.00mA limit of the transmitter loop current to be exactly 4.00mA according to the plant’s local standard. This is NOT for the purpose of ranging the transmitter! If trimming the 4.00mA limit is still desired then press ENTER.
