Crompton 264 Series Manual

Smart Tricolor or mono-color digital bargraph with a Universal Header Selectable

General Features

• A Tricolor or mono color (red or green), 0 segment high
brightness bargraph. Optional vertical or horizontal format.
• Red 4-digit LED display with range between –999 to
9999 (2000 counts). Optional green digital display.
• Front panel LED annunciators provide indication of set-
point status.
• Two 0 Amp Form C, and two 5 Amp Form A relays available.
• Auto-sensing AC/DC power supply. For voltages between
85-264 V AC / 110-370 V DC (Z) or 8-48 / 8-72 V AC / DC (Y).
• Optional isolated 6 bit analog output. User or factory
scalable to 4 to 20 mA, 0 to 20 mA or 0 to 0 V across
any desired digital span from ± one count to the full scale
range of – 999 to 9999 (2000 counts).
• Optional NEMA-4 front cover.
• Automatic averaging (6 sample moving average with eight
count replacement window to speed up display response).
• 24 V DC excitation is available to power external 4/20 mA
transmitters.
Software Features
• The bargraph can display,
full scale, any desired por-
tion of the digital reading.
• Bargraph center zero func-
tion.
• Four programmable set-
points.
• Setpoint  has delay-on-
make and delay-on-break
plus a special "pump on
pump off" mode that cre-
