DISPLAY
Inside the E110-P, all inputs (such as sensors and switches) and outputs (such as relays and

then displayed on a selection of screens when the unit is in OPERATOR-mode.
Normally, the information shown on the display is updated depending on the refresh rate selected in
the configuration settings. However, by pressing any of the keys, the display switches to refreshing
the information 8 times per second. After 30 seconds of key inactivity, the display returns to the
configured refresh rate.
