Operation Environment (temperature and humidity)
HMI should be operated in the following environment parameters to adjust screen brightness and
contrast to get the best image. If operating out of the range, LCD may be improperly displayed when
using for long time.
Ambient Operating Temperature: 0 ºC to 50 ºC (32 ºF to 122 ºF)
Relative Humidity: 10% ~ 90%, no condensation allowed
SM Card
SM card can be used to save and transmit data. Only SM card that formatted by HMI can be used on
both HMI and Windows® OS system. (Even it can be read/written in some format, but faults may occur
due to different format among Win95/98/2000/XP versions)
USB Flash Drive
USB flash drive can be used to save data. It also can be used to copy data from HMI and its format is
FAT32. When using USB flash drive to save data, we recommend the user should enter system screen
first and then remove the USB flash drive. Follow this process can ensure that the data is saved
completely in USB flash drive.
