    SAFETY FOR LIFE PRODUCT INFORMATION Introduction Service Information S260-75-1 provides installation, operation, and maintenance instructions for the Kyle Type S automatic load-transfer control. Read This Manual First Read and understand the contents of this manual and follow all locally approved procedures and safety prac- tices before installing or operating this equipment.

    Test Procedure 1. Check the indicating lamps by depressing the LAMP TEST switch (S6). All lamps on the front panel of the control (including fault block accessory if installed) should light with equal brilliance. 2. With phase Y and/or phase B energized, terminals 11 and 21 of TB1 will always show 120 Vac to ground (G 1 or G 2 ).

  • Page 13: Interconnecting Cables

    A conductor cable is required between the S control and each high-voltage switch to operate the switches. This cable is wired to a socket plug at the switch end and to either a plug or TB1 at the control end. Pin identification, and cable OD and maximum conductor size accommo- dated by the plugs are shown in Figures 10 and 11.

  • Page 16: Operating Instructions

    Source II high voltage switches can be paralleled in the manual operation mode even if SOURCE PREFER- ENCE switch, S4, is set for NP (non-parallel opera- tion). Make sure both sources are in synchronism if a manual parallel operation is to be performed. Failure to comply can result in misoperation (unintended opera- tion) and equipment damage.

    Time Range Selector The time range selector switch can be set to six different positions with a flat screwdriver. Each position indicates a time range. See chart below. The time range selector is preset to the time range of 0.1 to 99.9 seconds.

    The following assumptions are made: • OPERATION SELECTOR switch (S3) is in AUTO. • SOURCE PREFERENCE and RETURN MODE switch (S4) is in PREF l-P (Terminal 2 of each deck connected). • CONTROL MODE switch (S5) is in NORMAL. • S control is in a quiescent state.

  • Page 20: Remove The Control From Service

    Source I or Source II Preferred Operation G118.1 1. Set CONTROL MODE switch (S5) to TEST. This wilI remove the control from service and allow it to operate without operating the high-voltage transfer switches. 2. Check LATCH RELAY STATUS TEST terminals (T-1, T-2) to ground (T-3).

    No timers will start and latch relay (R1) will not transfer. 10. Place the CONTROL MODE switch (S5) to the normal position. If switch S5 is left in the TEST position, the S control will be inoperative on automatic operation. Indicating Lamps Although not essential to control operation, the indicating lamps provide useful operating information.
