■ DISPLAY

LED: 8 mm (.31”) 7 segment, red

Number of display digits: 4 digits for DATA display; 2 digits

for ITEM display

Range: -1999 to 9999

(decimal point position selectable)

PV indication: Input signal in engineering unit

Overrange indication: LEDs blinking

Power saving mode: Displays turn off if the keys are

untouched for a preset time period

LEDs: Red LEDs turn on when coils are energized.

(PL1 and PL2 for 2-point alarm. PL1, PL2, PL3 and PL4 for 4-

point alarm.)
