A typical Lockout Relay would have two positions "TRIP - RESET". Under normal

condition, the handle would be turned to "RESET" position and would remain mechanicallylatched at this position. The Lockout Relay contact LR which is in series with the LockoutRelay coil would be closed at the 'RESET" position only. The fault contact FC makes onlywhen there is a fault in the circuit.

When the Lockout Relay coil LR is energise, it would released the mechanical latchholding the handle at 'RESET" position and the handle would spring return to 'TRIP"

position. So long as FC remains at close contact condition ( due tothe presence of a faultin the circuit ) the handle will not latched at "RESET" position but would always spring

return to "TRIP "

APPLICATION

The Lockout Relay is a high speed Automatic Trip/Manual Reset auxiliary relay permit-

ting simultaneous operations of up to 48 contacts from 10A to 80A for AC and 10A to 63A

for DC.Lockout Relays are normally connected to the fault sensing contacts of the circuit

breakers. If a fault should occur, the Lockout Relays ensure that all the critical circuits areisolated and would remain isolated so long as the fault is not cleared. It's positive tripaction ensures that all the contacts would perform as to requirements and it multi-contact

arrangement eliminates the need for several control relays contacts.

PRINCIPLE OF OPERATION

TRIP RESET

When coil LR is energise, the mechanical latch holding the handle is release, and

the handle spring returns to "TRIP" position. Contact LR opens to isolate the coil from

the power supply to prevent overheating of the coil.

1. FEATURES OF DISCREPANCY SWITCH

a. Ratings available:

Size S00 - 10A Size S0 - 16A to 32A AC21 Size S1 - 20A to 63A AC21.

b. The lighting system is placed directly behind a translucent handle and consist of lamps

connected in series/parallel network as follows:

Size S00 consist of a single lamp Size S0 consist of 4 lamps with rating of 1.2W each. Size S1 consist of 6 lamps with rating of 1.2W each.

The advantage of having more than one lamp is that should one lamp fails, the other

lamps connected in the parallel network still operates but with reduced illumination in casea discrepancy condition occurs.

c. Auxiliary push-button contacts can be operated which operates when the handle isPush-in ( S0 AND S1 only )

d. Residual or slip-clutch contact can be incorporated on request ( S0 and S1 only ).

2. TYPES OF DISCREPANCY SWITCH

Kraus & Naimer discrepancy switch are available in the following sizes:a. Size S00 - for switch rating up to 10A. These switches are commonly used inmimic and mosaic panels. Low voltage switches of gold contact ( Type CA4-1 ) areavailable for electronics and thermocouple circuits.

b. Size S0 - for switch rating from 16A to 32A/AC21. These switches are commonlyused in mimic and mosaic panels. Low voltage switches of silver H- Bridge contact ( typeCAD12 ) or gold H-Bridge contact ( type CAD11) are available for electronics andthermocouple circuits.

c. Size S1 - for switch rating of 20A to 63A AC21. These switches are especiallysuitable for switching highly inductive loads e.g. circuit breaker coils etc.

b. Switch Ratings

The switch contacts operate when the handle is turn. The switches are suitable forboth AC and DC switching . Type CA4-1 with gold contacts are specially suitable for : Low voltage switching of electronics and thermocouple circuits due to it's lowcontact resistance.

Corrosive environment where the gold contact prevent oxidation of the contactsurface which can increases contact resistance.

In selecting the switch model for DC switching, the selection of appropriate switchdepends on: The DC supply voltage

The DC load current The type of load - resistive/inductive

In selecting the switch model for low voltage switching, the Dry Circuit Ratingshould not be exceeded. The Dry Circuit Rating refers to the relationship between thesupply voltage and load current. If the value exceeds, arcing may occur which would

remove the layer of gold on the contact.

The Size S0 lighting system consist of a lamp holder with four socket outlets to

accommodate 4 telephone bulbs type T6.8K Voltages available for the lamps are 6V, 12V,24V, 30V, 36V, 42V, 48V and 60V of rating 1.2 watts per lamp. Depending on the control

voltage, the lamps can be connected in series/parallel circuit. ( Fig. 7 ) The advantage of

this arrangement is that should any of the lamps fails, other lamps in the parallel circuit will

still lights up to indicate discrepancy reducing the danger of not knowing that there is adiscrepancy fault due to lamp failures.

In addition, high bright LED lamps type LE6.5B are available in T6.8K. Ratingsavailable for LED/T6.8K are 12VDC/35mA and 24VDC/15mA and available in Red, Yellow

h. Switch Ratings

Kraus & Naimer switches are design for both AC and DC switching. For DCswitching, the selection of suitable switch type depends on:

The DC Voltage The DC Load Current The type of Load - resistive or inductive. For rating on DC switching capacity,

please refer to the information on "DC Switching Capacity" for C, CA and Aswitches respectively.

It is possible to add residual contacts to give a self-holding effect by

adding the slip clutch optional extra M200

Fig. 21 - Typical Discrepancy Switch Circuit

a. Typical Specifications

When the handle of a discrepancy swi tch is turn 90 degrees, the mimic diagram ofthe control panel will immediately indicate any circuit interruptions . The handle of thediscrepancy switch will be illuminated to indicate a discrepancy between the conditionas indicated in the mimic panel and the actual condi tion of the circui t breaker. Forexample, if the circuit breaker and the discrepancy switch handle is in the is in the"CLOSED" positi on, the handle will not be illuminated because there is no discrepancy

between what is shown in the mimic panel and the actual condition of the circui tbreaker.

If the circu it breaker TRIP due to a fault condi tion, the handle of the discrepancyswitch will be ill uminated because a discrepancy arise i.e. the handle is still in the

CLOSE condition. The lamp wil l cut of f only when the handle is turn to the TRIPposition . This removes the discrepancy between the mimic diagram and the true

position of the breaker.Pushing-in and Turning the discrepancy switch handle at the TRIP position will

activates the tripping circuit of the breakerPush-in and Turning the handle at the 'CLOSE" posi tion wi ll activates the

closing circuit of the breaker.The switching conf iguration required is as shown in Fig. 22. Contact rating

required is 25A. Auxili ary contact required is 1 NO + 1 NC . Voltage of the lighting

system is 110V
