4. CONFIRMING POWER SOURCE VOLTAGE AND POWER<br />
CONNECTION<br />
4.1 Confirming Power Source Voltage<br />
4.1.1 Power supply in the control unit<br />
Confirm that the AC power being supplied to connector CP1 of the power supply in the control unit fulfills the<br />
following conditions.<br />
200 VAC +10% –<strong>15</strong>%, 50/60Hz ±1Hz, single phase<br />
220 VAC +10% –<strong>15</strong>%, 50/60Hz ±1Hz, single phase<br />
The following two LEDs are located on the power supply of the control unit.<br />
PIL (green) : Pilot lamp<br />
Indicates the power supply unit is ready for operation.<br />
ALM (red) : Alarm lamp<br />
This LED indicates the power supply has detected a fault. The fault could be the result of something like a<br />
direct current output short–circuit.<br />
For normal NC control unit operation, the PIL LED should be on and the ALM LED should be off.<br />
