4.1.13 Hysteresis (HYS)
The relay contact opens immediately when the temperature exceeds the adjusted
“
LIM
“ value, it closes only if the temperature falls below a value which consists
of “
LIM
“ and the adjusted hysteresis.
4.1.14 Wait time
(only available via interface commands, see Chapter 7, Data format UPP)
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 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).

4.2 Settings at the instrument
(only IN 510 and IN 520)
The buttons for parametrizing the IN 510 or IN 520 are inside the converter and are accessible
after removing the cover (4 screws).
Selection of parameters:
the
parameters are called with the button
PAR
(the sequence is described on
section 4). If no button is pushed for
approx. 15 s, the instrument switches
back to measuring mode with the
latest parameter settings. A changed
value of a parameter is automatically
stored after changing to another
parameter.
Up / down buttons (
):
After selection of one
parameter with the PAR button the up / down
buttons are used to set the available values.
Note:
Do not operate the converter permanently with open cover.
