The 505E's service panel consists of a keypad and LED display. The LED display has two 24-character lines that display operating and fault parameters in plain English. In addition, there are 30 keys that provide complete control from the front of the 505E. No additional control panel is required to operate the turbine; every turbine control function can be performed from the 505E's front panel.
