CHARACTERISTICS
10.1 Power
supply
2 wire.
Minimum voltage (TH7 y TH7T):
0.02 Z + 12 (Volt) (Z is the load in the current
loop in Ohm).
The minimum value is 12 VDC for Z=0 Ohm.
Minimum voltage (TH7H y TH7TH):
0..02 (Z+Rext) + 14 (Volt) (Z is the load in the
current loop in Ohm).
The minimum value is 18 VDC for Z=0 Ohm and
Rext=200 Ohm.
Maximum voltage:
36 VDC

Once the file is selected, press the “Program” button. A message “Programming device” will
appear.
The process takes about 90 seconds, after which the message “Device programmed” will
appear.
From this moment, the converter TH7 already has the new version of Firmware.
