COMET T4211 Temperature Transducer Sensor
PRODUCT DESCRIPTION
The P4211 transducer is designed for temperature measurement at °C or °F by
means of an external temperature probe with Pt1000 sensor.
The device settings can be changed with using the PC connected via the
optional SP003 communication cable (not included in delivery). The TSensor
software (free to download from
www.cometsystem.com) provides to change output
temperature range, temperature unit choice (°C or°F), output voltage range and
perform the adjustment.
Setting from the manufacturer
voltage output range: 0 to 10 V
temperature range: -200 to +600 °C
temperature unit: °C
DEVICE INSTALATION
Devices are designed for wall mounting. There are two mounting holes at the
sides of the case. The working position is arbitrary.
The connecting terminals are accessible after unscrewing the four screws in
the corners of the case and removing the lid. Pass the connecting cable
through released upper gland and connect the wires to terminals. For device
connection it is recommended to use a shielded cable with maximum length of 15
m and with external diameter of 4 to 8 mm. External temperature probe should
be of „shielded two-wire“ type. The cable probe shielding connect to proper
terminal only and do not connect it to any other circuitry and do not ground
it. Maximum probe cable length is 10 m. Finally tighten the glands and screw
the lid (check the integrity of the seal).
Devices don´t require special operation and maintenance. It is recommended to verify the accuracy of measurement.
WARNING
- The devices are not designed for locations with chemically aggressive environment.
- Don´t connect transmitter while power supply voltage is on.
- The cables should be located as far as possible from potential interference sources.
- Installation, commissioning and maintenance may only be carried out by personnel with qualification by applicable regulations and standards.
PROCEDURE OF MODIFICATION OF DEVICE ADJUSTMENT
- Install TSensor configuration program on the PC (take care about installation of drivers for USB communication cable)
- Connect SP003 communication cable to USB port of the PC (installed USB driver detect connected cable and create virtual COM port)
- Unscrew four screws and remove the lid (if device is already installed to measuring system, disconnect wires from terminals)
- Connect SP003 communication cable to the device (see picture)
- Run installed TSensor program and continue in accordance with its instructions
- When new setting is saved and finished, disconnect the cable from the device, connect wires into its terminals and place the lid back to the device
ERROR STATES OF THE DEVICE
The error status of the transducer is indicated by the value of the output voltage. The voltage value less than -0.1 V indicates low resistance of temperature sensor (short circuit) or serious error (contact distributor of the device). The voltage value about 10.5 V indicates high non-measurable resistance of temperature sensor (opened circuit).
