INTRODUCTION
This service manual contains field maintenance data for PD-1 Vital Relays (Figure 1-1). The purpose of the manual is to provide signal maintenance personnel with the data needed to understand PD-1 relay operation and how to perform field maintenance inspection and testing of the relays. Vital relay scheduled maintenance consists of periodic inspections and tests. The inspections and tests verify the relays are performing within the minimum In-Service Application Limits as specified on the Application Information Sheets for the relays. These sheets are contained in the Appendix at the rear of this manual. Relays not meeting the In-Service Application Limits must be replaced. Relays removed from service must be shopped for further testing and repair.

PD-1 RELAY MOUNTING OPTIONS
PD-1 relays satisfy the special needs of vital circuits in railroad and transit signal systems. PD-1 plug couplers are available for both front and rear service. This enables the PD-1 relays to be mounted in relay racks where rear service is possible, or on a· wall or shelf where front service is necessary. For shelf mounting, a support bracket is combined with a front service plug coupler. All wires are terminated on the plug coupler by removable solderless plug connectors. The plug connectors are available with or without a locking feature. 1.5
MAGNETIC CIRCUIT
Magnetic circuits are constructed of non-aging material. The magnetic air gap is not disturbed when the coil or contacts are removed 1.6
CONTACTS
Contact fingers and springs are manufactured of spring-tempered phosphore bronze. Individual contacts are removable and easily replaced. Movement of the armature operates the heel spring and assures proper contact wiping. Plug connectors are tin-plated. Contact material for low voltage front contacts is silver carbon. Heel and back contacts are made from fine silver. Heavy duty contacts are silver-to-silver.

A cover of transparent molded non-yellowing material houses the relay contacts and armature structure. The cover is sealed to its frame by pressure against a gasket, providing a tight dust-proof moisture-protected assembly. 1.8
FRONT TEST POINT
This testing facility is in series with the coil control circuit to permit deenergization of the relay while in service without disturbing the relay or wiring. The test point permits measuring of the relay coil current by insertion of a PD-1 current test probe. 1.9
RELAY VOLTAGE
PD-1 relays are manufactured for different input or control voltages. For specific voltage values refer to the relay's Application Information Sheet contained in the Appendix at the rear of this manual. Higher voltages can be used, but the maximum dissipating power of the coil should not exceed lOW. 1.10

( FUNCTIONAL DESCRIPTION 2.1
INTRODUCTION
This section contains functional descriptions of each type of PD-1 vital relay. Description of general operation of the relays is presented first. This is followed by brief descriptions of specific relay types. 2.2
DC VITAL RELAY GENERAL OPERATION
Figure 2-1 illustrates the structure of a typical de vital relay. The arrangement shown in Figure 2-1 is a simplified drawing of a vital relay. Figure 2-2 illustrates the PD-1 style of vital relay. The major difference between the two illustrations is the location of the relay's coil and armature. The PD-1 style of vital relay has its coil mounted vertically in the rear of the relay structure and its armature installed on the bottom of the relay structure, as shown in Figure 2-2. The electrical and magnetic operation of most styles of vital relays is the same. 2.3
DC BIASED VITAL RELA VS
A biased relay is equipped with a permanent magnet and arranged so that the relay armature picks up only when de current is flowing in the coil in a prescribed direction. The AAR defines a biased relay as: "A relay that will operate to its energized position by current of one polarity only, and will return to its deenergized position when current is removed". The schematic symbol for the biased relay is: SINGLE COIL OR

NOTE The illustrations in Figures 2-3 through 2-5 are functionally applicable to all styles of vital relays. Remember, however, the physical arrangements can be different. With no current passing through the coil, the permanent magnet is positioned so that its magnetic flux passes through the armature, permanent magnet, pole pieces, and core, as shown in Figure 2-3. This condition holds the armature in the deenergized or dropped position. The high reluctance (magnetic resistance) of the air gap prevents magnetic flux from flowing between the armature and the pole piece extension. Assume that current is applied to the coil circuit, and current flow through the coil is in the direction in which its magnetism opposes the magnetism of the permanent magnet, as shown in Figure 2-4. This condition is comparable to a high reluctance in the path of the permanent magnet flux. The resulting magnetic flux path is through the core, pole piece, pole piece extension, and the armature. As a result, the relay is energized with the armature in the energized or picked position. HINGE SPRING

The armature remains up as long as the coil is energized. When the coil circuit is opened, the magnetic force opposing the permanent magnet is destroyed. Once more, the flux of the permanent magnet resumes the low reluctance path through the pole piece and armature. Since there is no force to hold the armature up, it drops away from the pole pieces. Assume voltage of the opposite (reverse} polarity is applied to the coil {Figure 2-5}. This creates a magnetic force, which aids the magnetic force of the permanent magnet, and the flux remains through the permanent magnet, armature, and pole pieces. Thus, with vo_ltage of the opposite polarity, the armature is not picked up.

LIGHT OUT RELA VS
The PD-1 Light Out Relay is designed for signal light-out detection applications. The relay is energized when the signal lamp being monitored is lit. It is deenergized when the lamp is burnt out. The relay is a biased neutral relay with two coils, that are electrically separate but magnetically coupled. The schematic symbol for the light out relay is:
LOR
OR
N12---4
One of the coils (0.15 or 0.37 ohms) is wired between relay terminals LlO and RlO. Connected between these terminals and in parallel with the relay coil is a diode rectifier. In a signal lighting circuit, the signal's ac voltage is applied through this light out relay coil and rectifier circuit to the signal lamp. When a signal lamp's filament is not open, ac current flows through the 0.15 and 0.37 ohm coil and rectifier circuit. Polarity of the rectifier with respect to the coil must be correct for the relay to operate when the ac voltage is applied. As shown in Figure 2-6, energy is applied to the relay coil during the positive excursions of the ac power source. Being a biased relay, when the coil polarity is correct, the relay energizes.
RECTIFIER AC SOURCE

AC Operated Relay Coil 2-5

After the relay energizes, a path is completed through a set of front contacts of the Light Out Relay. Through these front contacts, de voltage of the correct polarity is applied to the second coil (350 or 0.086 ohms) through terminals L8 and L9 of the relay. After the relay is energized by ac lamp current flowing through the first coil, energizing of the second coil holds the relay energized. 2.5
MAGNETIC STICK RELAYS
The magnetic stick relay is similar in construction and operation to the biased relay. However, the armature is pivoted at its center and uses two permanent magnets; one at each end of the armature. The schematic symbol for the magnetic stick relay is:
The design is such that the armature remains in the last operated position with full contact pressure after energy is removed from the relay coil. The relay moves to the alternate position when de voltage of opposite polarity is applied.

With polarity of the permanent magnets as shown in 2-7, and current flowing in the coil as indicated, the armature rotates counterclockwise. This action pulls up the contact driver, which, in turn, closes the heel and normal contacts. When the polarity of the voltage across the coil is reversed, the resultant magnetic flux, as shown in Figure 2-8, forces the armature to rotate clockwise. This pushes the contact driver down, which, in turn, opens the normal contacts and closes the heel and reverse contacts.

MAGNETIC HEAVY-DUTY AND HEAVY-DUTY CONTACTS
2.6.1 Magnetic Blowout Relay The biased magnetic blowout relay is similar in structure and operation to the de biased relay. The exception is the use of magnetic blowout heavy duty contacts. Small permanent magnets are affixed to the contact springs, behind and close to the heavy duty tips. The purpose and effect of these magnets is to disperse or blow out an electric arc before it has the chance to grow and burn and otherwise damage the contacts. The coil symbol for the biased magnetic blowout relay is the same as that of the standard biased relay described in paragraph 2.3. The schematic symbol for the magnetic blowout heavy-duty contact is:

The relay is similar in structure and operation to the de biased relay with the exception of having heavy-duty contacts which can carry loads up to 15 amperes. Standard contacts are designed to carry loads up to 4 amperes. The coil symbol for the heavy-duty contact relay is the same as the biased relay, but its contact symbol is: CJ

SLOW PICKUP AND SLOW RELEASE (DROPAWAY) RELAYS
The slow pickup and slow release relays are biased relays, having special timing characteristics. Slow pickup and slow release refers to the relative timing of relay action. The desired pickup and release timing characteristics are achieved through the use of RC circuits. The schematic symbols for these relays is: SLOW PICKUP +A
SLOW DROPAWAY +A

Timing characteristics are changed externally by combinations of coil connections, and snubbing of coil circuits by combinations of rectifiers, capacitors, and resistors (Figure 2-9). As stated on the PD-1 Application Information Sheets for slow pickup and slow release relays, the snubbing components may be external or built into a plug coupler.

UNION SWITCH & SIGNAL
The switch overload relay is placed in the switch machine motor circuit. The relay is constructed with two coils; an operating winding and a stick winding. The operating winding is wired in series with the switch machine motor. When current is excessive, the operating winding energizes the relay. The relay is held energized by the stick winding, causing deenergization of switch control relays that directly control the motor circuit. The activation time, hence the sensitivity of the overload relay, is determined by a low resistance element connected across the operating winding. The resistance element has a positive temperature coefficient so that a substantial increase in current causes a proportional increase in resistance. During normal current conditions, most of the current passes through the resistance element with little or no current through the operating coil. An increase over the normal current level increases the resistance of the element, causing more current to flow through the operating coil. If the overload persists, the operating coil receives sufficient current to activate the relay armature. 2.9
FLASHER RELAY
The PD-1 flasher relay is a biased neutral relay with heavy duty front and back contacts. When the relay is used with an external electronic driver unit (Figure 2-10), it will provide between 41 and 45 flashes per minute when the voltage applied is 8-18V de. The driver unit is assembled in a package that plugs into a standard octal socket. The driver unit contains shop-adjustable controls to set the on-time and off-time of the flasher.

TEST PERFORMANCE
The PD-1 relay tests can be performed without the DC Relay Test Stand. But the test stand simplifies the test setup and reduces the time needed to test the relays. The following paragraphs describe how to test each type of relay with and without the test stand. Whether or not the test stand is used, the basic test setup is as shown in Figure 3-1.
.
NOTE
As a general rule when testing de relays, such as the PD-1 relays, an ammeter is used to test relays with a coil resistance under 100 ohms, and a voltmeter is used to test relays with a coil resistance over 100 ohms. 3.5
DC RELAY TEST STAND
The DC Relay Test Stand is manufactured by US&S. Its formal title is Relay Test Stand PN-150/PN-250 Relays. To enable its use to test PD-1 relays, a Plug Coupler Adapter is provided with the test stand. The Plug Coupler Adapter is wired to a PN-250 frame which is inserted into the PN-250 mounting base on the test stand. The Plug Coupler Adapter sits on a test bench or other flat surface and the PD-1 relay to be tested is then inserted into the Plug Coupler Adapter. The DC Relay Test Stand is described in detail in US&S Service Manual 6360. The manual describes the test stand and contains detailed procedures for the testing of PN type de relays. To reduce frequent reference to the manual, the following information is included in this manual. Refer to Table 3-1 and Figure 3-2 for the location and function of each test stand control and indicator. It must be remembered that all of the test stand controls and indicators are not used for the testing of PD-1 relays. Located in the center of the test stand (Figure 3-2, item 19) are 30 contact indicators. The contact indicators are arranged in five rows of six indicators per row. During the tests, the indicators provide a visual indication of the relay's contact configuration and whether they are open or closed. During PD-1 relay testing, as shown in Figure 3-3, the contact indicators in colu,."tlils 1 through 3 only are used. Row A and D indicate Front contact closure, Row B and E indicate Back contact closure. The Heels (H) can be imagined 3-2

NOTE
As a general rule when testing de relays, such as the PD-1 relays, an arruneter is used to test relays with a coil resistance under 100 ohms, and a voltmeter is used to test relays with a coil resistance over 100 ohms. 3.
Slowly adjust the power supply output control to increase the output, as indicated on the de voltmeter or arruneter, as appropriate, to Charge the relay. (The Charge value is four times the relay's working value, which is specified on the relay's Application Information Sheet.)
4.
Reduce the power supply output to zero and set Sl to Normal.
b. Test the relay as follows: 1.
Slowly increase the de power supply output until the relay armature reverses position and normal (bottom) contacts close. Note the value. It should be no greater than the Pick-up Maximum In-Service Application Limit value specified on the relay's Application Information Sheet.
2.
Reduce the power supply output to zero and set Sl to REVERSE.
3.
Slowly increase the de power supply output until the relay armature reverses position and reverse (upper) contacts close. Note the value. It should be no greater than the Pick-up Maximum In-Service Application Limit value specified on the relay's Application Information Sheet.
