4 HPC-250HT Control Operation
The HPC-250HT User Interface is mounted on the front door of the -E2 cubicle of the cabinet.
It is operated by tapping on the screen with the designated touch panel operating pen. Make
sure to only use the designated touch panel operating pen to operate the touch screen of the
User Interface.
The display background illumination can be activated by turning the Start/Stop key operated
Spring-Return Switch in either “Start” or “Stop” position for an interval of less than three
seconds.
The backlight illumination of the HPC-250HT User Interface will stay enabled for 30 minutes
counting from the last actuation of the Start / Stop Key-Operated Spring-Return Switch.
4.1 HPC-250HT Control Menu
After connecting the auxiliary power supply to the HPC-250HT the system performs a first
main initialization.
The termination of the main initialization requires about one minute after every connection of
auxiliary power supply.
Note, that the auxiliary power supply is connected to the cubicle the first time during
installation of the HPC-250HT. Under regular conditions, during normal operation without
having the auxiliary power supply interrupted, the HPC-250HT does perform the main
initialization only once.
