ElectricalPartManuals . com www . ElectricalPartManuals . com PLACING REGULATOR IN SERVICE (without interrupting the load) For detailed instructions see page 9. 1. The by-pass switch 1, Fig. (7, 10, 13), is in series with the line and will of course, be closed if the line is carrying load.

7 Close the disconnect switch 2, Fig. (7, 10, 13), on the source side of the regulator. This excites the regulator to full line voltage. 2. Run the tap changer to "Neutral" position. 3. Turn transfer switch and voltage source switch to "off". 4. Remove both fuses on front of control panel. 5. Close the disconnect switch 3, Fig (7, 10, 13), on the load side of the regulator. CHECKING REGULATOR ACCUISTAT CONTROL 6. Open the by-pass switch 1. The regulator then carries load. 7. Replace fuses on front of control panel. 8. Set voltage source switch to "Normal".

8 9. Adjust the control (see Page 13) and set the transfer switch to "automatic" position. CAUTION Source (S),Ioad (L) and neutral (SL) designation of bush ings stamped on cover. Check before connecting to line. For detailed instructions to check band width and voltage see page 10. 1. Move transfer switch from "automatic" to "raise" 3. Check the regulator operation in the "lower" dirac-position and allow regulator to operate about five tion in the same manner. steps. 4. If the control operation is satisfactory, return the 2. Return the transfer switch to "automatic" operation.

9 Transfer switch to the "automatic" position. After a short time delay the regulator will operate, and come to rest. REMOVING REGULATOR FROM SERVICE (without interrupting service) 1. Run the regulator to the "Neutral" position. 2. Turn transfer switch and voltage source switch to "off". 3. Remove both fuses on front of the control panel so the regulator cannot operate. 4. Close the by-pass switch 1, Fig. (7, 10, 13), thus shunting the regulator. 5. Open disconnect switch 3, Fig. (7, 10, 13), on load side. 6. Open disconnect switch 2, Fig.

10 (7, 10, 13), on source side. CAUTION When removing the regulator from service, never open the neutral disconnect switch until the source discon nect switch has been opened. Failure to observe this rule may cause a high enough voltage to be induced in the windings to damage the insulation. NOTE: Above instructions and those on Page 9 based on using individual switches for source, load and by-pass. If combination type regula or by-pass switch is used, the by-pass switch No. 1, Fig. (7, 10, 13) ls the by-pass element of the combination switch.
