Barksdale UAD 3-V3 User manual

2. Starting operations
- The pressure switch should be installed and operated only by authorized personel.
- Cover and bottom of the device form a function unit. Exchanging the parts can cause measuring errors
or malfunctionning. For wall mounting remove the four front cover screws and the front cover. Then
fasten the device with four screws to the wall and finally remount the front cover. To damp strong
vibrations shock mounts must be used.
- Connect the sensor to the (3-pin + PE) cube plug at the bottom side of the UAD 3 - V3.
- The electrical connection (supply, analog output switching contacts) must be carried out according to
the connection tables depicted on the top of the device by removing the cover cap and insert the cable
through the cable gland PG 13,5. If required, additional cable glands can be installed in the cover cap
by breaking out the perforated cavities.
- The electrical connection must be carried out in accordance with the VDE 0100 regulations. In order to
ensure trouble-free operation it is essential to connect the protective lead.
- If inductive loads (magnets, contactors, etc.) are connected to the switch relays, suitable protective
devices (varistors etc.) must be provided.

4. Operation
After the unit is switched on, the unit starts an automatic self-test.
The device is menu operated and configured by the three keys on the front.
With the „M“ key (= mode) you change between the operation / indicating level to the dialog values and the
adjusted / actual values. With the keys („⇑“ = up) and („⇓“= down) you change between the dialog values
in the menu or change the values / functions in the menus.
A change of any configuration starts always with the M-Mode and indicated by the flashing cursor. After a
change has been made with the up- resp. down-key the M-mode key must be pressed to confirm each
configuration; to set numbers, each digit has to be confirmed with the M-Mode before adjusting the next
one. By confirming the last digit the new configuration will be stored in the memory.
Pushing the down key at the end of the sub-menu the software will switch automatically to the main-menu.
If the dialog is not continued within two minutes the device automatically returns to the measuring mode.
5. Key lock
Activating the („⇑“ = up) and („⇓“ = down) keys together for more than 5 seconds will block any changings
in all menues; shown by „LOCK“ in the display.
In this mode, all configuration values can be checked only, but not changed.
Repeating this action will unlock the configuration menu and shown by „UNLK“ in the display.
6. Error handling
The internal self-check software will monitor the proper functioning of the unit. When any of the following
failures will occur, the flashing display will indicate the following text:
