Example application 1
– step by step
With a flow sensor (measuring range: 40 m/s; output signal: 4 ... 20 mA)
the flow velocity shall be indicated in m/s. The analog output of the LED
display shall signal a measuring range of 1 m/s (
≙
4 mA) up to 20 m/s
(
≙
20 mA). If the flow velocity exceeds 15 m/s an alarm signal is issued
over relay 1, without hysteresis or delays.
- Install LED display in desired position
- Plug jumper in housing cover for
“current measurement”
- Connect supply of sensor to LED display
- Connect analog output of sensor to LED display
- Connect analog output and relay output 1 of LED display
- Connect current supply of LED display and close housing
- After switching on supply voltage: Initialization, followed by indication
of an “unconfigured“ measurement value on the main display
- Call-up configuration menu by pushing
for 2 seconds
