GENERAL INFORMATION
1.1
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.
1.7
COVER
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
PLUG COUPLER
Plug couplers must be ordered separately. As stated, two types of
plug couplers are available: rear service and front service
(Figure 1-2).

The PD-1 Relay with a front service plug coupler (Figure 1-3) is
supported by two rods. These rods are secured to the shelf or
wall. When in its working position, the relay is secured by two
nuts. For service, the two nuts are removed and the relay is
pulled forward on the support rods until the plug coupler contacts
are accessible. The design offers maximum space utilization, since
relays can be mounted on a wall or on both sides of a relay rack

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 RELAYS
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:

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.

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 voltage 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:
LO
-cffi~J+
LOR
OR
N12---i
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. fn 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.

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:

2.6.2 Heavy-Duty Contact Relay
The heavy-duty contact relay is a biased relay with heavy-duty
contacts. 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

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:

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. The schematic symbol

INSPECTION AND TEST
3.1 INTRODUCTION
This section contains procedures to be used to periodically
inspect and test PD-1 Vital Relays at their field locations. How
often each type of vital relay is to be inspected and tested is
specified in its Application Information Sheet contained in the
Appendix at the rear of this manual.

Armature moves freely and that moving heel contacts meet the
front and back contacts squarely and practically
simultaneously.
3.4
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 columns 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

DC Relay Test Stand or similar test setup per Figure 3-1.
3.6.1.2
Test Setup.
When a DC Relay Test Stand is used, the
following procedure creates the test setup required. When the test
stand is not used, the test setup shown in Figure 3-1 must be
created. The non-test-stand setup can use the rack mounted plug
coupler/relay but all system wiring connections must first be
removed from the plug coupler. All test connections can then be
made to the rack mounted plug coupler.
In the following test stand setup procedure, the item numbers are
those used on Figure 3-2:
a.
Ensure the AC POWER switch (4) and TIMER switch (23) are
set to OFF.
b.
Ensure the power switch on the de power supply is set to
off, and adjust its output voltage control to the OV
output position.
NOTE
As a general rule when testing
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.
c.
Using test leads, connect either the de voltmeter or
ammeter (per above Note) to both the power supply output
and the relay coil block jacks A+/A- (8), observing the
correct polarity.
NOTE
The above connections are for single
coil relays. For double coil relays,
whose coils are wired in series, the
meter is connected to the A+ and Bjacks with A- and B+ jacks jumpered.
