,f P 33 2 3.0 Precautions and Limitations 3.1 When operating the LOWER / RAISE Control Switch for the CTC-11 Generators voltage and governor load control, the control command
_w ill be executed as long as the control switch is held in the y LOWER or RAISE position. Operator has to anticipate time lag of the controlled value after release of the control switch.
3.2 Following the power block start-up or the use of manual load controls (GOVERNOR CONTROL switch), the automatic load controls are blocked. Automatic load controls (MIN, BASE and PEAK push-buttons) are restored by giving the Power Block a second ALL START signal.
3.3 If the Power Block Master Control switch is taken to STOP a second time the units will go off ratchet sear. If the units so off the ratchet gear, it will have to be reset at the CTG-11 Control Center. When reset, the unit will go back on ratchet gear.
3.4 When a unit (s) is loaded without any warm-up period, Attachment 2 must be completed every 15 minutes for the associated unit (s).
4.0 Prerequisites 4.1 43S Keylock Switch located on CTC-11 Control subpanel in the Fermi ! Control Room is in Fermi 2 position.
4.2 120kV circuit breaker control switch handles are removed from the Feral 1 Control Room Panel #2.
4.3 43P Selector Switch in the CTC-11 Control Center is in the REMOTE position.
4.4 43 Selector Switch on Individual unit control panel in the CTG-11 Control Center is in the REMOTE position.
4.5 Synchronizing Mode Selector Switch is in the OFF/ REMOTE position on CTG-11 Control Center Power Block Panel.
4 . 6. Unit is ready to start as indicated by the green backlighted READY TO START indication on Panel H11-P811.
4 7 The NSS has given permission to perform this test on the Surveillance Performance Form.
4.( Verify all radiation protection requirements are met, as listed on the Radiation Work Fermit, if required.

, (Minimum). /
NOTE: The automatic synchronizing will adjust voltage to 107-124V and the frequency to SI -6f 45, as noted on Panel Hil-P811.
2.0 Loading
NOTE (1): There are two sets of controls available to adjust the MW output of the CTG-ll Generators ( Abu s Aus Aewanc.).
NOTE (2): Following the power block start-up or the use of manual load controls (GOVERNOR CONTROL switch), the automatic load controls are blocked. Automatic load controls (MIN, BASE and PEAK push-buttons) are restored by giving the power block a second ALL START signal.
Manual - Governor Control Switches on the unit control subpanel.
Automatic - Load Selection - Minimum, Base or Peak on the Power Block Control subpanel.
NOTE (3): At this point the operator must decide to operate the unit load in Manual or Automatic.
2.1 Manual Load Control NOTE: When operating the Lower / Raise control switches for the unit voltage and Governor Load controls, the operator should be aware that the command signal is present as long as the switch is held in the LOWER or RAISE position. The operator has to anticipate time lag of the controlled value after release of the control switch.
2.1.1 Turn the Governor Control Switch to RAISE and increase load to Base load (13-15 MW). /
