ATTENTION It takes up to 16 hours to fully recharge the battery
pack and you can use the SFC continuously for up to 24 hours
before the battery pack needs recharging.
The ambient operating temperature limits for the SFC are –10 to 50°C
(14 to 122°F) with relative humidity in the range of 10 to 90% RH.
• For transmitters operating in the Analog Mode, be sure to put an
analog control loop into its manual mode before initiating SFC
communications with the transmitter. Also, be sure any switches that
may trip alarms or interlocks associated with the analog loop are
secured or turned OFF. Communication superimposes digital signals
on the loop wiring that could affect the analog control signal.
• Be sure the power supply voltage does not exceed 45Vdc.
The ST 3000 transmitter and SFC were designed to operate with
voltages below 45Vdc.
• Be sure there is at least 250 ohms of resistance between the SFC and
the power supply for proper communications.
