presents the principle of relay outputs operation for two thresholds mode for an
example values of other parameters. In this mode parameter
“SEt2”
is accessible in common
with
“SEtP”
, this parameter describes a second threshold of the relay output. The parameters
“HYSt”
,
“modE”
,
“t on”
,
“toFF”
,
“unit”
and
“AL”
are connected with both
“SEtP”
and
“SEt2”
thresholds. While the controlling process, the relay output changes his state depends
of both
“SEtP”
and
“SEt2”
thresholds in similar way as it was described in one threshold
mode.
If two threshold mode is used,
“modE”
parameter defines state of the relay output when
the input value occurs in a particular zone defined by
border values
of both
thresholds
. The
relay can be turned on if the input value is contained in
zone A
(
“modE”
=
”in”
) or
zone B
(
“modE”
=
”out”
) and turned off if it is contained in the second one
).
The sequence of thresholds “
SEtP
” and “
SEt2
” can be set in any order, due to the
control of relay outputs is done depend on difference between thresholds values
(
zone A
) and outside of threshold values (
zone B
).

DEVICE PROGRAMMING
The device menu allow user to set all parameters connected to operation of
measurement input, control modes, critical situations behaviour, communication via RS-485
and access settings. The meaning of the particular parameters is described in chapter
Some of the parameters can be accessed without entering menu (quick view mode).
After pressing
[^]
or
[v]
button, name of the threshold (e.g.
“rEL1”
) and its value will be
displayed on the display in alternating mode. If
[^]
or
[v]
will be pressed in 5 sec again, the
next treshold will be displayed, else the device returns to the measurement mode. If a
free
access
is enabled (see chapter
), user can change the value of
selected threshold by pressing
[ENTER]
).
If particular parameter has been changed and confirmed in quick view mode, its
new value is displayed in alternating mode with parameter name by few seconds.
Confirmed changes may be checked or user can switch viewed parameter pressing
[^]
or
[v]
button.
7.1.
PROGRAMMING MENU
To enter main menu (being in the measurement mode) user must to press and hold
at least 2 sec.
[ESC/MENU]
button.
If the user password is defined (see parameter
“Scod“
,
menu
“
SECU”
), operator have
to enter correct one before proceeding to menu options . Entering of the passwords is similar
to the edition of numeric parameters
(see chapter
)
,
however
presently editing digit is showed only on the display, other digits are replaced by “-” sign. After
entering of last digit of the password first menu position will be displayed (if the password is
correct) or warning “
Err
” in other case.
Pay attention when device parameters are being changed. If it is possible, turn off
controlled installation (machine).
