Installation 5.3.1 Signal Output Power + Power – Signal Ground Signal Out p ut Figure 8: Wiring of the Signal Output (mA or V) The signal output can be configured either as current or as voltage output.
Installation 5.3.2 Head Ambient Temp. / Alar m Output This output can be configured either as output for the head ambient temperature (default configuration) or as an alarm output.
Installation You may use a solid state relay for the alarm output. The outp ut is short circuit resistant with 100 Ω out put imped ance.
Installation 5.3.3 Thermocouple Output If you are using a J ‐ or K ‐ thermocouple you must inst all a compensation cable.
Installation 5.4 Inputs FTC The three inputs FTC1, FTC2, and FTC3 are used for the external control of the unit.
Installation 5.4.1 Emissivity Setting (analog contr olled) The input FTC1 can be configured to accept an analog voltage signal (0 to 5 VDC) to provide real time emissivi ty setting.
Installation 5.4.2 Emissivity Setting (digital controlle d) The sensor’s electronics contains a table with 8 pre ‐ installed settings for emissivity.
Installation 5.4.3 Ambient Background Temperature Compensatio n The sensor is capable of improving the accuracy of target temperature me asurements by taking into account the ambient or background temperature.
Installation • Ambient background temperature compensation from a second temperature sensor (infrared or contact te mperature sensor) ensures extremely accurate results.
Installation 5.4.4 Trigger and Hold Function The FTC3 input can be used as ex ternal trigger in conjunction with the software trigger mode setting “Trigger” or “Hold”.
Installation Hold: This mode acts as external generated hold function. A transition at the input FTC3 from logical high level to ward logical low level will transfer the current temperature toward the output.
Installation 5.5 Connec ting to the PC via RS232 The RS232 interface comes with each model. Connect a single unit with a RS232 COM port by using the connection kit RAYMINC ON.
Installation 5.6 Installin g of Multiple Sensors vi a RS485 The distance between the sensor and a computer can be up to 1200 m (4000 ft.) via RS485 interface.
Installation For an installation of two or more sensor s in a RS485 network, each sensor is wired parallel to the othe rs. You may connec t up to 32 units.
Installation Go to the menu <Setup> <Sensor Setup>, and then select the register <Advanced Setup>. Use <Polling Address> for selecting the requested address.

Operation object), the output signal reaches only 90% magnitude of the actual object temperatur e after the defined average time.
Operation 6.4.2 Peak Hold The output signal follows the object temperature until a maximum is found.
Operation 6.4.3 Valley Hold The output signal follows the object temper ature until a mini mum is found.
Operation 6.4.4 Advanced Peak Hold This functi on searches the sensor signal for a local maximu m (peak) and writes this value to the output until a new local maxi mum is found.
Operation 6.4.5 Advanced Valley Hold This function works similar to the advanced peak hold function, except it will search the signal for a local minimum. 6.
