FIXED UFM AND COMPONENTS (Continued)

6

 1  RS232/RS485 Interface boards

Digital Interface boards RS232 or RS485 are 

available as an option to provide digital com-

munication via ASCI strings. 

 2  Input for temperature sensors 

QMF-PT100 (3-wire)

The two temperature sensors (feed and return 

pipe) can be connected in order to measure 

heat/thermal output. The flow transmitter always 

includes the capability for heat/thermal output 

measurement. Note that (if required by customer) 

the QMF-PT100 inputs can also be used to reset 

the counters. If you use this reset function you 

cannot measure heat/thermal output at same 

time. 

 3  Relay output (potential-free)

This output is potential-free NO (normally open) 

relay output. Use this output to establish an 

alarm (for example, when exceeding a certain 

flow speed). 

4  Analog output 4-20mA (active)

The 4-20mA outputs can be used to submit 

measurement data like flow, thermal output and  

velocity to the Programmable Logic Controller 

(PLC). These outputs are in active mode (supply 

voltage provided internally by flow transmitter).

5  USB- Interface

Used for firmware updates. Standard USB (micro 

USB)- cable required to connect to a PC.

Used to reset unit (for hang-ups). 

7  Power Supply

Location for connecting the supply voltage. QStar 

UFM is available as AC (90-240VAC) and DC 

(18-36VDC) version. 

CONNECTOR BOARD

FIGURE 12: 

Connecting Terminals 

Always use the correct voltage for the UFM. 

Improper supply voltage might seriously 

damage the flow transmitter. Check the type 

of power supply on the name plate (printed 

on right side of enclosure of flow transmitter.

 

CAUTION

Wiring 

The connection terminals are located under the lower 

cover. Remove the two screws and plastic cover to 

gain access to the connection terminals.
