Aalborg TIO Totalizer I/O Flow Monitor/Controller - Manual (Page 71)

d) Parameters configuration
Following parameters must be configured:
• Device Function (See 5.3.12 Submenu “Device Function”). If TIO is connected
to flow controller, then “Controller” function must be selected. If TIO is
connected to flow meter, then “Meter” function must be selected.
• Full Scale Range (See 5.3.14 Submenu “Device Calibration”). Full
Scale Range parameter must be set equal to the mated device full
scale flow rate in Litr/min.
• Fluid Std. Density (See 5.3.14 Submenu “Device Calibration”). This
parameter is required only when mass-based engineering units are selected.
User may configure other parameters (see Paragraph 5.3) according
to individual preferences and application requirements.
7. TROUBLESHOOTING
7.1 Common Conditions
Your TIO Totalizer Input/Output Flow Monitor/Controller was thoroughly checked at
numerous quality control points during and after manufacturing and assembly opera-
tions. It was calibrated according to your input and output configuration. It was care-
fully packed to prevent damage during shipment. Should you feel that the instrument
is not functioning properly, please first check for the following common conditions:
• Are all cables connected correctly?
• Are the connector pin outs matched properly?
• Are J2 input / output jumpers configured correctly?
• Is the power supply correctly selected according to requirements?

NOTE: When TIO is connected to flow meter, output circuitry is
not used. Jumpers J2A, J2B, J2C configuration is not applicable in
this case and they should not be changed. In order to disable analog
output, jumper J2B must be removed.
,
NOTE: If “Full Scale Range”, “Device Function” and “Fluid Std.
Density” parameters not set properly, device may have erroneous
reading and unpredictable behavior.
,
When several devices are used a power supply with appropriate current rating
should be selected. When interchanging with other manufacturers' equipment,
cables and connectors must be carefully wired for correct pin configuration.
