Description
Oelay Control Outputs
The FC-5000 flow computer has two Form C relay outputs� All control functions
are always available by dedicated relay outputs� Unneeded outputs may be left
unconnected�
Relays are used for High Alarm, Low Alarm, High/Low Alarm and Totalizer�
• TB3 and TB4 can be powered directly from mains circuits rated up to 240V�
• TB3 and TB4 must be powered through circuits that are insulated from mains by
at least basic insulation�
• Sources of power connected to TB3 and TB4 need to be limited to 240V AC and
fused at 5A (NC) and 3A (NO) or less�
• Other than TB3 and TB4, this equipment is suitable for connection to external
circuits that are insulated from mains by at least double insulation (SELV),
including the power supply to the unit connected to TB1�
Power Supply
The power supply used must be isolated from mains by double or reinforced
insulation (for instance, SELV power supply)�
The FC-5000 flow computer operates on 10…40V DC or 9…28V AC supplied by
any suitable source that also meets the requirement listed above�
The selected power supply must be capable of supplying a minimum of 8 Watts�
Configuring the Unit
The FC-5000 flow computer is designed for many types of applications� See
“Setting Up a Flow Meter” on page 29
for instructions on configuring your
FC-5000 flow computer to your specific requirements�
The
Advanced Setup
menu includes features such as K-factors and selection of the
control outputs� All information is stored in EEPROM memory and will not be lost
in the event of power failure�
Display Information
The FC-5000 flow computer has a large transflective LCD with a bright LED
backlight that displays symbols and digits for measuring units, status information
and keyword messages� See
