CAUTION
!
Before putting protective relays into service,
remove all blocking which may have been
inserted for the purpose of securing the parts
during shipment. Make sure that all moving parts
operate freely. Inspect the contacts to see that
they are clean and can close properly. Operate
the relay to check the settings and electrical con-
nections.
1.0 APPLICATION
The ARS relay is a high speed auxiliary that has a 20
volt low energy level input and a multiple contact out-
put. It may be used as a tripping auxiliary for relays
such as the SP and SDG-1 or as an oscillograph
interface.
The driving device must be capable of providing an
input to the ARS of 6 milliamperes at a level of 15 to
20 volts.
2.0 CONSTRUCTION AND OPERATION
The type ARS relay is composed of 1 or 2 AR units
with series resistors, a printed circuit module, and
indicating contactor switches (ICS) when required,
mounted in a FT-11 or FT-22 case, depending upon
style.
AR Unit
The relay consists of four stationary contact screws,

four leaf spring moving contacts, a moving armature
and card assembly, which operates the moving con-
tacts; a U shaped laminated core, a coil, a frame, a
molded insulation block and a series resistor.
The armature and card assembly slip over a hinge
pin which is inserted in the laminations. The moving
and stationary contacts are mounted on the molded
insulation block. The molded block and coil and lami-
nation assembly are mounted to the frame. All con-
tacts are fine silver.
When the coil and resistor are energized, the arma-
ture is attracted to the laminations. The card moves
with the armature thereby operating the moving con-
tacts. The tension of the moving contacts is the reset-
ting force.
High speed operation is obtained by the low inertia of
the moving parts, a sensitive electromagnet, and the
proper L/R ratio of the operating circuit.
Printed Circuit Module
The printed circuit module contains the proper num-
ber of transistors, protective zener diodes, capacitors,
resistors, and diodes for the buffered amplifier cir-
cuitry controlling each AR unit. With the rated supply
voltage to the relay, the proper signal voltage applied
to an input terminal will cause the related AR unit to
pickup. The AR unit will then energize the ICS (if
used), which will seal around the AR unit contacts.
The removal of the input voltage will cause the AR
unit to drop out.
Indicating Contactor Switch Unit (ICS)
The dc indicating contactor switch is a small clapper
