5 SET-UP AND OPERATION
FS10 Function Overview
The FS10 flow monitor may come configured for use as a flow or temperature meter. The output of the switch configuration is a SPDT relay contact or
binary collector to ground [N-channel MOSFET] output (sync). A 4-20 mA output signal is also active as a signal reference. In the transmitter configu-
ration, either the flow or temperature functions may be assigned to the 4-20 mA output. The table below shows the possible output configurations,
including the status of the LED bar display.
• Flow measurement will be mapped using CUST_FLOW_MIN and CUST_FLOW_MAX in the 4-20 mA output configuration.
• Temperature measurement will be mapped using CUST_TEMP_MIN and CUST_TEMP_MAX in the output configuration and reflected
in the 4-20 mA output when configuration 4 or 5 is selected. The default temperature range mapped to the 4-20 mA
output is 0 °F to 250 °F [-17.8 °C to 121 °C]. Rescaling temperature output may be performed with the PC interface program.
The output configuration setting is normally factory set but may be changed in the field if required. Caution should be used when making any
configuration changes, as the monitor may not have been properly calibrated to accommodate the new setting. Only the RS232 interface may
be used to make a change in output configuration.
