Connecting 24V DC Power to the Control & Operator’s Panel
Since the
i
-series controls do not have built-in power switching capabilities, the new GE Fanuc
operator’s panel for i-series is equipped with ON/OFF push-buttons for easy power switching.
In order to take advantage of this feature, we recommend that you wire the 24V DC power
according to the diagram below.
As mentioned in the beginning of the chapter, you must supply the regulated 24V DC power
source (24V ± 10% which includes ripple and noise) for the control and operator’s panel
connection unit. When selecting the power supply, keep in mind the following things:
1
. The switching device on the operator’ s panel is rated at
a maximum of
8 amps.
2
.
The incandescent bulbs which light up each push-button on the operator’s panel draw
40mA of current each.
3
.
The current requirements for each control will depend on the hardware options you
choose for your control (if any). Refer to the appropriate manual to calculate the
current requirements of your control:
