7. Energizing Control Cab
a. Performance Check
(1) Ensure that CB 301 (Cab Main) and CB 302 (60Hz Control Voltage) are activated. At Motor Starter
Panel (Cabinet No. 4) perform the following steps:
(2) Depress "60 Hz Pwr" button to activate 60 Hz, 120 V ac power.
(3) Depress #1 button to activate 28 V dc power supply # 1 28 V dc.
(4) Depress #2 button to activate 28 V dc power supply # 2 28 V dc.
(5) At Cabinet No. 4, activate power at Limit Control Panel.
(6) Activate power at Calculating Counter.
(8) Activate power for AEDATS.
(a) For AEDATS II, activate power at the AEDATS Processor Chassis (Cabinet #2).
(b) For AEDATS IV, activate power at the UPS and Processor Chassis (Cabinet #2).
8. Shutting Down Control Cab
a. Performance Check
(1) Exit AEDATS software and shutdown AEDATS Processor.
(a) For AEDATS II, shutdown power at the AEDATS Processor Chassis (Cabinet #2).
(b) For AEDATS IV, shutdown power at the Processor Chassis, then UPS (Cabinet #2).
(3) At Cabinet No. 4, shutdown power for Limit Control Panel.
(4) Shutdown power at Calculating Counter.
(5) At Motor Starter Panel (Cabinet No. 4) perform the following steps:
(6) Depress #2 button to deactivate 28 V dc power supply # 2 28 V dc.
(7) Depress #1 button to deactivate 28 V dc power supply # 1 28 V dc.
(8) Depress "60 Hz Pwr" button to activate 60 Hz, 120 V ac power.
9. DC Voltmeter (0 to 50 V dc)
a. Performance Check
(1) Ensure that the power is off at the TI Meter Panel Assembly.
(3) Energize Power Supply #1 (CB304) and #2 (CB303) via the circuit breaker panel and set the DC
Voltmeter Power Supply Selector Switch to Power Supply #1.
(4) Access Power Supply #1 and #2 in cabinets #6 and #8 respectively. Place the positive (+) lead of
the digital voltmeter to the positive (+) 28 V dc output stud of Power Supply #1, and place the
negative (-) lead of the digital voltmeter to the negative (-) DC output stud of Power Supply #1.
(6) Set the DC Voltmeter Power Supply Selector Switch to Power Supply #2. Perform steps 4 and 5 for
Power Supply #2.
(7) 714 power supply 24 VDC perform step 4.
10. AC Voltmeter
a. Performance Check
(1) De-energize power to the Meter Panel Assembly via the circuit breaker panel.
(2) Verify that the AC Voltmeter reads zero. If not, adjust the meter mechanical zero screw as necessary.
(3) Energize the power to the Meter Panel Assembly.
(4) Set the digital voltmeter to AC volts.
(5) Access the rear of CB301 (Main Circuit Breaker) on the circuit breaker panel.
WARNING
Hazardous voltages are present on all exposed terminals.
Extreme care must be exercised to prevent injury or death.
