Menu 8, Menu 10 – Set switch-off point for switching output
(S1, S2 outputs S1on, S2on).
Set a switch-off value for the relevant output. (S1, S2 output
S1oF
,
S2oF
)!
Menu 11, Menu 12 – – Select hysteresis or compare mode
(Select S1, S2 output mode)
&
Select the hysteresis mode (HY 1 – HY 2) or compare
mode (CP 1 – CP 2)! You can find a description from the hysteresis and compare mode are in
chapter
6.4.
Menu 13, Menu 15 – Set switch-on delay
Set the switch-on delay value for the relevant output.
(Output S1, S2, d1on, d2on); (0-100 s).
Menu 14, Menu 16 – Set switch-off delay
Set the switch-off delay value for the relevant output.
(Outputs S1, S2, d1oF, d2oF); (0-100 s)
Menu 17 and Menu 18 – Maximum / minimum pressure display
&
Displays the high pressure (HiPr) or low pressure (LoPr)
value during the measurement process (values are lost when power is gone). To delete the
values, press the two buttons at the same time again within 1 second.
Menu 19 – Measured value update (display)
Sets the display refresh cycle length. (0.0–10 sec)
Menu 20, Menu 21 – Simulate contact outputs
(only 4…20 mA / 3-wire adjustable)
The state of the switch outputs can be simulated. Select, activate or
deactivate the up and down buttons (outputs S1, S2 from tES1, tES2).
Menu 22 – Simulate analogue output
(only 4…20 mA / 3-wire adjustable)
The value of the analog output signal can be simulated. Select one of the
following settings: “oi 4” (4 mA or 2 V), “oi12” (12 mA or 6 V) and ”oi20” (20 mA or 10 V)
Menu 23 – Error signal definition
(only 4…20 mA / 3-wire adjustable)
Set the desired error signal (this is sent out if there is an error).
Permitted options: “0FF” (no error signal), “C 0” (0 mA or 0 V), “C L0” (3.5 mA or 1.75 V) and
“C HI” (23 mA or 11.5 V). The error message appears only when Menu 6 “HILo” is set to “on.”
Menu 24 – Offset compensation / position correction
(only 4…20 mA / 3-wire adjustable)
Enter the POSI menu; if offset
≠
ambient pressure it is necessary to place
the device under pressure pended on mounting position (the pressure reference has to
correspond to the zero point of the pressure measuring range); press the two buttons at the
same time; "oF I" will be appeared on the display; press the two buttons at the same time;
"Pro2" will be displayed; press the two buttons at the same time; the display will now show
"o"; the reference value can now be inputted with the push buttons.
The reference value is, for example, 5% (
−
0.2 bar [2.9 psig]) of the measuring range:
−
1–15 bar (
−
14.5
−
217.5 psig); enter 5% using the buttons, then press the two buttons
simultaneously; the display will show "oF5". Accordingly, the right and stable pressure should
be added to the system (
−
0.2 bar [2.9 psig]).
If the measured value displayed on the display is a bad value, the operating sequence
must be repeated.
A position correction is required if the installation position is different from the calibration
position (as this may cause a little deviation of the signal, so the displayed value will be wrong).
The analogue output signal (for devices with analogue output signals) will have no effect; if you
move the offset, the entire scale will be moved.
Menu 25 – Load default settings
(only 4…20 mA / 3-wire adjustable)
This option restores the factory default value for all settings. To reset the
factory defaults, press the two buttons at the same time after selecting this option. Note that
any changes you have made so far will be lost, so the password will also be reverted to “0005.”
Menu 26 – Load configuration
(only 4…20 mA / 3-wire adjustable)
Load configuration stored on the device (Menu 32). (Choose from 1 to 5).
Menu 27 – Store configuration
(only 4…20 mA / 3-wire adjustable)
Saves the device configuration settings. Select a number between 1 and 5.
SPECIAL MENUS:
To access the special menu, select “PAof” with the “ ” or “ ” button, then press both
buttons to activate the menu item. “1” appears on the display.
Special Menu 1 – Full-scale compensation
Full-scale compensation is necessary if the indicated value for full scale
differs from the real full-scale value in the application; compensation is only possible with an
appropriate reference source if the deviation of the measured value is within the defined limits.
Set “0238” with the “ ” and “ ” keys; confirm with both buttons; “FS S” will appear on
the display. Now it is necessary to connect the pressure reference, which corresponds to the
measuring range’s end value, to P1. P2 must stay open! Press both keys again, to store the
signal being emitted from the pressure switch as full scale; the display will show the set
endpoint, although the entire range detection signal has been shifted.
Please note that the analog output signal (on devices with analog output) remains
unaffected by this change.
Special Menu 2 – Offset compensation / position correction
(not available for 4…20 mA / 3-wire adjustable)
Set "0247"; the menu description is identical with menu "P0SI" (menu 36) for
3-wire-devices).
Special Menu 3 – Load default settings
(not available for 4…20 mA / 3-wire adjustable)
Set "0729". The menu item description is the same as "FAct", “Menu 37” for
3-wire devices.
Special Menu 4 – Set password
Enter “0835”; apply setting by pressing the two keys together; the display will
say “SEtP”; now set the password using the “ ” - or “ ” -keys. Any number from 0 to 9999
can be entered except for the following code numbers: 0238, 0247, 0729, and 0835. After
entering the new code number, save it by pressing the two buttons together.
7. TROUBLESHOOTING
Fault
Possible causes
Fault detection / solution
No output signal:
Faulty connection.
Check the connection.
Broken wire.
Check all wires with a cable tester.
Defective measuring
device (signal input).
Check the ammeter (and its fuse) and the analogue
input of the signal processing unit!
Analog output
signal too low:
Load resistance too high. Check the value of the load resistance!
Power supply failure.
Check the power supply and power / current on the
transducer / transmitter!
Output signal
slightly offset:
The diaphragm of the
sensor is severely
contaminated.
Cleaning with non-aggressive cleaning solutions, soft
brush or sponge.
The diaphragm of the
sensor is calcified or
crusted.
It is recommended to clean the device carefully to
ensure all the dirt is completely removed.
Large offset in
the output signal:
The diaphragm of the
sensor is damaged (by
overpressure or
mechanically).
Check the diaphragm of the sensor, if it is damaged
send the device back to the manufacturer.
8. MAINTENANCE AND REPAIR
The instrument does not require regular maintenance. If necessary possible dirt deposited
should be cleaned off. The warranty conditions are included in the warranty card.
Dismount the device only when it is depressurized and disconnected! Drain the medium before
dismounting the device.
If necessary, clean the diaphragm carefully with a non-aggressive cleaning solution, soft brush,
or sponge. Improper cleaning may cause irreparable damage to the diaphragm.
For this reason, never use sharp objects or pressurized air for cleaning the diaphragm. Before
returning the device for repairs, it must be cleaned carefully, the parts in contact with the
medium that might contain harmful substances must be decontaminated. Our official form
(Returned Equipment Handling Form) must be enclosed. Download it from our website
www.nivelco.com
. The device must be sent with a declaration of decontamination. Please
provide a statement in the declaration that the decontamination process is completed, the
device is clean and free from harmful materials, and there are no hazardous substances on it.
