Connecting the lCD to the aC line Power
Before connecting the 24 VDC power to the electronics, ensure that
the electronics are connected to the sensor. Otherwise, damage to the
electronics is possible.
The Ethernet LCD requires 24 Volts DC (± 1 Volt) and 3.3 Amps. If you have
your own 24-Volt DC power supply, Figure 3-6 shows the pinouts for the LCD
power-input connection. A braided, shielded cable is recommended. If you
purchased the Dycor DC power supply module, follow the directions below to
connect to the AC line power.
1. Connect the DIN connector from the DC power supply module to the power
input connection on the Ethernet LCD.
2. Align the key and push in the connector.
3. Push the outer ring over the connector and rotate clockwise until the ring
locks in place (Figure 3-6). The Dycor DC power supply model accepts
either 110 or 220 Volts, 50/60 Hz AC input.
4. Plug the DC power supply module into the appropriate AC power outlet.
