3.1.4 Wait time tw
When using a pyrometer with RS485, it is possible that the connection is not fast enough to
receive the pyrometer’s answer to an instruction of the master. In this case, a wait time
(between 00 and 99 bit) can be set to slow down the data transfer (e.g.: tw = 02 at a baud rate
9600 means a wait time of
2
/
9600
sec).
3.1.5 Connecting additional analyzing devices
Additional analyzing instruments, such as a LED digital display instrument, need to be connected
to a power supply and the analog outputs from the pyrometer. Other instruments, like a
controller or printer, can be connected to the display in series as shown below (total load of
resistance max. 500 Ohm).
3.2 Mechanical Installation
3.2.1 Sighting LED targeting light
For exact aiming to the object the pyrometer is equipped with a red LED
targeting light. At the main distance “a” this light shows its smallest diameter
and a sharp image. In other distances the point gets diffuse. The targeting light
only marks the center of the measuring spot, not the size
Without targeting light a tape can be used to determine the distance between object and
pyrometer.
If the pyrometer is supplied with power the LED targeting light is automatically active. It can be
adjusted if the targeting light is off whether the pyrometer is connected to the power supply
(via software InfraWin in the window pyrometer parameters, see 4). Independent of this
setting the targeting light can be switched on or off at this point.
Additionally it is possible to connect a push button to the pyrometer (see 3.1.1 Pin assignment
of the male socket on the back of the pyrometer) to switch on and off the targeting light.
3.2.2 Optics
The pyrometers are equipped ex works with one of the following optics. These optics are
focusing to a certain distance, i.e. in these distances each optics achieves its smallest spot size in
relation to the measuring distance. The spot size will change in any other distance (shorter or
longer).
