Safety

2 Safety

2.1 General

Any person who is tasked to carry out work with the device must have read and understood the operat-

ing instructions before beginning. Operation and maintenance of the system may only be performed by

trained personnel.

2.2 Electrical Connection

When connecting or when working on the mains voltage, the general safety guidelines are observed,

e.g. when connecting power transformers. Supply voltage can be lethal when touching. Improper instal-

lation can cause serious injury or physical damage. Only qualified personnel are allowed to work with

mains voltage.

1.6 Through-lens Sighting / View Finder

Devices with through lens sighting and temperature range above 1400°C are equipped with an adjusta-

ble eye protection filter in the eyepiece to reduce glare at high measurement temperatures. The unpro-

tected look at temperatures >1400°C can damage the eyes function permanently.

Safety precaution: before looking toward the high temperatures, always first adjust the eyepiece with

help of a replacement light source by turning onto the darkest area. A safe method is the adjustment by

looking at a lamp.

1.7 Responsibility of the Operators

If the device is used in the commercial sector the operator is subject to the legal responsibilities for

workplace safety.

In addition to the safety instructions in this manual follow the regulations of safety, accident prevention

and environmental protection.

4.1 Cable Colors and Pin Assignment (14 Wire Connection Cables)

The electrical connection of the pyrometer (supply voltage and measuring signal) will be done via the

connector on the rear panel. For this purpose, pre-assembled connection cables are available as ac-

cessories (see 9.4 Accessories). To prevent accidental short circuits, cable wires not in use should be

secured to the supplied screw terminals.

NOTE: In general we recommend the use of the new 14 wire connection cables.

Be careful when using an old 12-wire connector cables (before 2015):

Connection cable for the previous models Metis and Sirius cannot be connected without re-

strictions on a M3 pyrometer!

Old connection cables are bridged in the cable connector to pins E-C and D-F. Connecting such a ca-

ble to a M3 pyrometer, serial interface and analog output 2 and digital input / output 3 are connected

and the galvanic isolation between the outputs is bypassing. Thereby the pyrometer is not destroyed,

but the functions are no longer available. Using such a cable only analog output 1 is available as output.

4.1.1 Power Supply

With connection of the supply voltage (standard 24 V DC, possible range 18–

30 V) the unit is ready for operation with the following factory settings (changing

the settings is possible via Software SensorTools (see 7). By connecting the

power supply, the current firmware version is displayed for a few seconds.

Interrupt the power supply to turn off the pyrometer, e.g. by disconnecting the

connector.

Power status LED: Indicates the operating status of the pyrometer:

orange in the self-test phase (ca. 2 s; )

Green when the pyrometer is ready to operate

Red when an error occurred (see 10.3 Troubleshooting).

4.1.2 Analog Output 1 and 2

The analog outputs are adjustable (e.g. for a temperature dis-

play device) to:

0–20 mA or 4–20 mA

Furthermore, the following adjustments can be done:

Analog Output 1 always provides the measured tempera-

ture (always the temperature selected and displayed on the

device display and the control window in SensorTools; see

also 7.2.2 Control window).

(Note: With older firmware versions, the same settings are

possible as at analog output 2. A firmware update to the lat-

est version eliminates this possibility and prevents, that the output of analog output 1 is accidentally

different to the displayed temperature signal. Firmware update see section 8).

Analog Output 2 can be assigned to provide different signals:

- Flame temperature

- 2-color temperature

- 1 channel temperature (optional channel 1 or 2)

- Device temperature

- Control output (= manipulated variable) when equipped with PID controller

4.1.3 Configurable Inputs / Outputs

3 ports are each available as:

Digital output: output of a switching signal (invertible, see under

7.2.3 Various settings Logic NO / NC) at:

- Device ready to operate (device ready and error-free after self-

test)

- Material detection (limit switch turns on when exceeding the

beginning of temperature range)

- Limit switch when a certain temperature threshold is exceeded

or falling below

- Exceeding the maximum allowed device temperature

- Signal strength too low (as dirty window alarm function: enables to detect the degree of contamina-

tion of the pyrometer‘s optics, viewing window or identify interferences (dust...) in the IR sensor’s

sight path and trigger an alarm if necessary).

Digital input: A voltage pulse of 24 V, pulse

length adjustable via software (minimum 3 ms,

factory settings 100 ms) 7.2.3 Configurable

Inputs / Outputs debounce time enables:

- Clear of maximum value storage (see 6.9)

- Load pyrometer configuration (see under 7.2.3

Configurable Inputs / Outputs “parame-

ter selector” or 7.2.4 Setups).

Analog input (only M3 and only on input / output 3, adjustable

via Software, see Analog Input): About a 0–20 mA current

source, some parameters can be adjusted externally between

their smallest and largest setting value:

- Soot factor (0 mA = 0.5; 20 mA = 2.5)

- Emissivity slope (0 mA = 0.8; 20 mA = 1.2)

- Emissivity for every channel (0 mA = 0.05; 20 mA = 1.2)

Electrical Connection

4.1.4 Serial Interface RS232 / RS485 (switchable)

The serial interface is used for digital communication of the pyrometer with another computer, for exam-

ple a PC for data transmission to the software SensorTools. Via interface always all temperatures are

transferred (2-color and one channel temperatures) as well as device information and parameters.

The maximum transmission speed (in Baud) is limited by the cable length, it is halved with each dou-

bling of the transmission path.

RS232: about 7 m cable length with 19.2 kBd. Adjustable are values from 4.8 to 115.2 kBd.

RS485: about 2 km with 19.2 kBd. Adjustable are values from 4.8 to 921.6 kBd.

Connecting one pyrometer via

RS232 or RS485:

In a short RS232 or RS485 connection to the mas-

ter (computer receiving the data), the pyrometer is

connected directly as a point-to-point connection

with the master.

It is advantageous to connect all interface cables

in order to avoid reflections.

Connecting several pyrometers via RS485:

For a reflection-free operation with longer cables, pay attention to the correct cable termination. Termi-

nation at the physical bus is on front and rear.

Master at the

beginning:

Master in the

middle:

When operating multiple devices (up to 32 are possible), each device needs to assign its own address

(directly on the device or via software SensorTools), under which it can be addressed later. For this

purpose, initially, each device must be connected individually and provided with an address (00-97). Af-

ter that, all devices can be connected.

If specific parameters for all devices should be changed simultaneously, the global address 98 is used

(there is no response from the device). If the address of a device is unknown, you have the opportunity

to address each device independently of the set address with the global address 99 (connect only one

device).
