Display Showing
“
4-20 Level Open
”
The wiring on the 4-20mA Level current loop is not properly closed or the system voltage is not high enough for the Level Transmitter to source 20mA.
•
Ensure that the 12/24V power is connected to the positive input of the level transmitter and the negative output of the transmitter is connected to the
“
Level
” input on the 4
-20mA Input Card. See wiring instructions on page 10.
•
Ensure that the voltage supplied to the transmitter is high enough. See instructions to verify the system voltage on page 8.
Display Showing
“
4-20 Pressure Open
”
The wiring on the 4-20mA Pressure current loop is not properly closed or the system voltage is not high enough for the Pressure Transmitter to source 20mA.
•
Ensure that the 12/24V power is connected to the positive input of the pressure transmitter and the negative output of the transmitter is connected to
the
“Pressure” input on the 4
-20mA Input Card. See wiring instructions on page 12.
•
Ensure that the voltage supplied to the transmitter is high enough. See instructions to verify the system voltage on page 8.
“Level” and/or “Pressure”
Connected LED Flashing
The
“Level” and/or “Pressure”
4-20mA current loop has not been wired correctly.
•
Verify that the wiring is correct using the procedure on pages 10 to 12.
•
If the Level and/or Pressure inputs are not being used, disable them using the DIP switch on the 4-20 card. See procedure on page 13.
“Auxiliary” Connected LED Flashing
The “Auxiliary” DIP Switch is set to “Enable”
but should be set to “Disable”
.
•
Verify the DIP switch settings using the procedure on page 13.
“Level” and/or “Pressure”
LEDs are All Off and the Card Seems Non-functional
The “Level” and/or “Pressure”
DIP Switches are
set to “Disable” or the Input Card is not getting power.
•
Verify the DIP switch settings using the procedure on page 13.
•
Verify that the Input Card is seated properly on the terminal card header and that no pins are bent or missing.
