System status codes
OK
No error or warning flags present – normal operation.
OR
Over range – Either reduce the flow or change the user selected flow
range. Always make sure the user selected flow rate is greater than
or equal to the expected maximum flow. If an overrange condition
exists the analog output will not track it. The totalizer will however
indicate properly even past the user specified flow rate.
42
4-20 mA warning – Check the 4-20 mA wiring and make sure there
isn’t an open circuit. If this output is not used and you don’t want to
see this warning, attach a jumper wire between terminal TB2-19 and
TB2-21.
LC
Low flow cutoff – No action should be needed unless you have the
low flow cutoff set below where the user wants it. The factory default
is 2%.
TM
Test mode – If the board is placed in the factory test mode for some
reason, the meter will not indicate live flow.
CH
Coil high – This message could appear if there is a short circuit or
partial short circuit in the detector coil wiring or sensor. Another
possibility is that the coil current setting is too high.
CL
Coil low – This normally happens when the coil is not connected or in
an open circuit mode. Another possibility is that the coil current
setting is too low.
6.1.5 D1
This indicates the status of the set point output.
ON
Flow rate is at or above the programmed set point value.
--
Flow rate is below the programmed set point value.
