T ype S Automatic Load-T ransfer Control Installation, Operation, and Maintenance Instructions 2 The instructions in this manual are not intended as a sub- stitute for proper training or adequate experience in the safe operation of the equipment described.
Introduction Service Information S260-75-1 provides installation, operation, and maintenance instructions for the Kyle ® T ype 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.
Description of Operation The T ype S control is designed for use primarily with Kyle T ype VR, VLR, VRV , TSC, and C three-phase, load-break switches in automatic load-transfer schemes. In a typical scheme, service to a critical load is normally supplied from a preferred source.
Pre-Installation The T ype S automatic load-transfer control is pro- grammed to customer ’s specifications and thoroughly tested before shipment from the factory . Perform the fol- lowing pre-installation test setup and procedure to verify the operation of the standard S control.
A typical automatic transfer scheme is illustrated in Figure 2. Initial Programming The control must be programmed with all necessary operating settings prior to operation with energized switchgear . For the desired settings refer to the Operating Instructions section in this manual.

Interconnecting Cables Interconnecting cable conductor size is dependent upon the distance between the control, switches, and potential transformers. Maximum lengths of various cable combi- nations for No. 18 through No. 12 AWG conductors are shown in T able 2.
Fault Block Shielded Cable T able 3 shows the maximum distance between the con- trol and the high-voltage switches for a range of conduc- tor sizes and fault-block settings. The table is based on conductor voltage drop and saturation of the current sensing transformers in the switch.

Before energizing the installation, an understanding of the functions of the operating controls and indicating lights is essential. (See T able 4 and Figure 14). Initial Operation T o place the automatic transfer scheme into service, pro- ceed as follows: 1.
Timer Settings The two digital timers are identical. One timer controls the time required to transfer from the preferred source to the alternate source, the other timer controls the time to trans- fer from the alternate source to the preferred source.
Automatic T ransfer , Preferr ed to Alternate The following assumptions are made: • OPERA TION SELECTOR switch (S3) is in AUTO. • SOURCE PREFERENCE and RETURN MODE switch (S4) is in PREF l-P (T erminal 2 of each deck connected). • CONTROL MODE switch (S5) is in NORMAL.
No Prefer ence Mode Assume the Source I high-voltage switch (SW-I) is closed and Source II high-voltage switch is open. With the SOURCE PREFERENCE and RETURN MODE switch (S4) in NO PREF-NP (T erminal .
General This troubleshooting guide is intended to assist in localiz- ing problems that may be encountered in the operation of the load-transfer scheme. After the problem area has been localized, general troubleshooting and circuit tracing techniques can be used to pinpoint the cause.
S260-75-1 21 ! SAFETY FOR LIFE No Prefer ence Operation 1. Set CONTROL MODE switch S5 to the TEST posi- tion. This will remove the control from service and allow operation without operating the high-voltage transfer switches. 2. Check the setting of the SOURCE PREFERENCE switch (S4).
Output of the Control T o determine if the problem is in the control or the high- voltage transfer switch, proceed as follows: 1. Disconnect the switches from the control. 2. Place OPERA TION SELECTOR switch (S3) to MANUAL. 3. Place SOURCE PREFERENCE and RETURN MODE switch (S4) to NO PREF .
Manual Control Functions Abnormal output readings at TB1 indicate a malfunctioning control. This procedure describes the terminal functions under manual direction and suggests areas for investigation. 1. T erminals 1 1 and 21 provide the power to charge the springs in the switch actuator and are constantly energized.

The fault block accessory is mounted in the upper right corner of the back panel of the control, Figure 18. Controls and instructions for operating the accessory are located on the front panel above the input fuses, Figure 19.
The actuating level multiplier for the inrush restraint fea- ture for phase faults is set by a jumper wire connected to a tab on the circuit card. T abs are provided for X1, X2, X4, X6, X8 and BLOCK settings. The duration of the raised level is set by a knob on the top of the timer (Figure 18).

Ground Fault Operation The ground current (the vector sum of the phase cur- rents) flows through the ground actuating resistor , R306, to produce a voltage across the primary of input trans- former TR1, proportional to the ground current.
T esting Fault Block Operation The operation of the fault block accessory can be checked by backfeeding a 500:5 (or other available ratio) current transformer , located in the primary loop of one phase of the preferred source high-voltage switch, from a variable 120 V ac source.
5. Open SW1 and SW2 to simulate a backup clearing the fault. The PREFERRED TO AL TERNA TE TIMER will start and the preferred source high-voltage switch (HV1) will open when the timer runs out, but the alternate source high-voltage switch (HV2) will not close.
Inrush Restraint The inrush-restraint feature prevents inrush currents above the minimum actuating level from actuating the accessory . This is accomplished by raising the phase actuating level by some multiple for a predetermined time after service is restored.
