[UP] or [DOWN] :
- moves to the next or previous parameter name
- changes the value of the edited parameter
[ESC] :
- cancels the change of the edited value (and displays the parameter name again)
- displays again the set/measured value (after holding time > 1 s)
7. RANGE OF INDICATIONS. CHANGE OF A VALUE SET FOR AN OUTPUT
1. Depending on the setting of parameter 2:
dira
(chapter 8, Table 8), the value of the set/measured signal may
be presented directly in real values (mA or V, when 2:
dira
=
unit
) or may be calculated to any programmable
range of indications suitable for the specific application (parameters 3:
rbot
and 4:
rtoP
, when 2:
dira
=
boto
).
2. In the set value display mode, when the [ UP ] or [ DOWN ] button is pressed, the value is changed by a preset
step (parameter 10:
StEP
). The changes of the output signal are proportional to the changes of the displayed
value. When the [SET] and the [DOWN] buttons are pressed simultaneously, the output is immediately set to any
permissible value in the range (0/4 mA, 0/2 V, 3:
rbot
or 8:
LiLo
) while pressing the [SET] and the [UP] buttons
simultaneously causes the output to be set at the upper permissible value of the range (20 mA, 10 V, 4:
rtoP
or 9:
LiHi
). Also, the output signal can be set in the parameter programming mode (parameter 11:
SEt
). Moreover, it is
possible to set a value outside of the indication range resulting from parameters 3:
rbot
and 4:
rtoP
. The value of
this overload is equal to ±5% (in accordance with the full range of changes of the output signal described in
chapter 4).
8. SETTING OF THE CONFIGURATION PARAMETERS
All the configuration parameters of the device are stored in the non-volatile EEPROM internal memory.
The parameters are set from the film keypad located on the front panel of the device:
−
from the set/measured value display mode go to the configuration menu (press [CONF] and hold it for more
than 2 seconds) If parameter 18:
Prot
=
on
(password protection is on) the display will show the
message
CodE
, and then
0000
with the first digit blinking, use the buttons [UP] or [DOWN] to enter the
password (default parameter 17:
PASS
=
1111
), to move to successive items and to approve the code, use the
[SET] button
−
after you enter the configuration menu, the mnemonic names of the parameters are displayed (
StYP
<->
dira
<->
rbot
<-> etc.); press the [UP] button to go to the next parameter and the [DOWN] button to go to
the previous parameter (a complete list of configuration parameters is presented in Table 8)
−
to change or view the value of the current parameter, press [SET]
−
use buttons [UP] or [DOWN] to change the value of the edited parameter;
−
approve the changed value of the parameter by pressing [SET] or cancel it by pressing [ESC] ; then return to
the parameter name display
−
exit the configuration by long pressing (>1 s) the [ESC] button; otherwise, the system exits the menu
automatically after approx. 2 minutes of idle condition
In the event of indications different from the actual value of the input/output signal, the zero and the sensitivity of
the sensor can be tuned to the specific signal: parameters 14:
cALo
(zero) and 15:
cALG
(sensitivity).
To restore the factory settings, when the device is switched on press button [CONF] and hold it until the password
menu appears (
CodE
), and then enter the following code
0112
.
