Figure 3–2: 469 DISPLAY
All messages are displayed on a 40-character vacuum fluorescent display designed for visibility under poor
lighting conditions. Messages are displayed in plain English and do not require an instruction manual to deci-
pher. When the keypad and display are not being used, the display defaults to the user-defined status mes-
sages. Any trip, alarm, or start block is displayed immediately, automatically overriding the default messages.
To perform a lamp test, press key for 2 seconds.
