9131 Rev. M 3.2 OPERATION 3.2.1 Initial Checkout This checkout is divided into two sections. In the first section, all control functions are checked. In the second, the high voltage functions are checked. If the CSC fails to perform properly at any step of this procedure, consult the troubleshooting guide in Section 4. 3.2.1.1 3.2.1.2 Control Functions ( ) 1. Set all CSC switches to the OFF position. ( ) 2. Apply Primary Power to the CSC. ( ) 3.
9131 Rev. M 3.2.1.2 3.2.2 High Voltage Functions Cont'd D. Attempt to turn on the CCR. Verify it does not turn on. E. After repeating Step A above, re-install the dead front cover on the CSC. F. Restore power to all circuits. Normal Operation In most cases, the CSC will be operated from a remote location. To affect this mode, set to remote and close the cabinet door. No other adjustments are necessary.
9131 Rev. M SECTION 4 MAINTENANCE WARNING INSTALLATION, SERVICE, MAINTENANCE OR OPERATION SHOULD BE PERFORMED BY QUALIFIED PERSONNEL ONLY. 4.1 PERIODIC MAINTENANCE The CSC should be inspected periodically as shown below: 4.2 INTERVAL ACTION 1 month (A) Visually inspect high voltage relays through clear dead front cover. 3 months (A) Perform Control Functions checkout per Section 3.2.1.1 to verify proper operation. 6 months (A) Isolate the CSC and CCR from all sources of electrical power.
9131 Rev. M 4.2 CORRECTIVE MAINTENANCE CONT'D WARNING VOLTAGES IN EXCESS OF 1000 VOLTS ARE PRESENT WHEN THE REGULATOR IS OPERATING. DO NOT ATTEMPT REPAIR OR SERVICING WITHOUT FIRST REMOVING POWER FROM THE REGULATOR. THE USE OF LOCK-OUT DEVICES IS RECOMMENDED FOR INSTALLATIONS WHERE THE POWER DISTRIBUTION PANEL IS NOT READILY VISIBLE FROM THE REGULATOR OR CSC LOCATION.
