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. It is automatically switched to an alter- nate, standby source if the [...]

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. Note: This procedure does not test complete control opera- tion. Th[...]

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. Mounting the Control Mount the S control in a convenient, accessi[...]

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. The longest combination for the partic- ular installation will determine the minimum con[...]

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. Lower actuating lev- els and lower multipliers could allow longer[...]

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. The switches on the front panel should be positioned as follows: A. S1 (MANUAL OPER. SOURCE[...]

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. The two digital timers feature the following informational indicators and adjustment controls: Dig[...]

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. • S control is in a quiescent state. • Source I high-voltage transfer [...]

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 4 of S4 connect- ed), loss of Source I voltage on one or more phases will open the Source I high-voltage switch (SW-I) as described in the Automatic T[...]

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. A funda- mental understanding of the basic operation is essential[...]

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). It should be in the center No Preference position. 3. Check LA TC[...]

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 . 4. With the control energized, check the voltage to ground[...]

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. General Description In response to fault current above preselected phase or ground levels, the accessory is activated and l[...]

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). The timer is infinitely adjustable 0.1 to 5.0 seconds.[...]

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. This volt- age is stepped-up, rectified, and impressed across the series resistor string R104, R105, R106 and R[...]

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. The 500:5 ratio provides approx- imately 1 Amp of output test current [...]

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. If alternate source switch (HV2) closes and the latch relay (R1) contacts are not opening,[...]

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. Ground actuating level detection is blocked for the duration of the raised phase actuat[...]
