Solution(s)
• Check for correct voltage (AC or DC) to the input of the Field
Connection Board. (See
Wiring Diagram).
• Check the main power source for blown fuse or tripped circuit
breaker. Reference your "as built" installation drawings for your
location.
• Check the fuses on the Field Connection Board. Reference fuse F1 and
F2 locations.
• Ensure that the meter is properly powered.
™
• Ensure that the computer cable is properly connected to the field
connection board (see
connector and check your interface pins (RS-485 or RS-232).
• Verify that the communication parameters of the Daniel MeterLink
program are set according to jumpers on the meter CPU board. See
Daniel MeterLink utilities
configuring communications.
• Check switch S-1 on the field connection board and ensure that it is in
the correct position (RS-485 or RS-232 communication).
Note
Note that S1 is located at the top left side of the board.
• Check for loose connections at the cable connectors. See
engineering drawings.
• Check the resistance of the transducers (should be approximately 1-2
Ω).
• Problem also may be caused by a bad Acquisition board or
interconnect cable. See
information.
• Check system status in Daniel MeterLink
flagged errors.
• Check the CPU board LEDs.
Increase the StackSize until noise level decreases (settings can be 1
(none), 2, 4, 8, or 16). If increasing the StackSize is not successful, try
turning on the filter or consult with Flow Lifecycle Services for Daniel
products if you are unsure of how stacking a signal can effect the meter's
operation. Refer to Technical Support under the Help menu of Daniel
MeterLink for contact information.
