Legacy Time Delay and

831 Series

SPDT, 15 A

Description

The 831 voltage sensor is a single-phase AC voltage sensing device capable of

monitoring and reacting to overvoltage and undervoltage conditions . This product is

designed to be wired across terminals A1 and A2 with the voltage being monitored .

The two LED lamps indicate when the input voltage is present (green LED) and

when the output is energized (red LED) .

The Umax dial is used to set the upper trip-point for the voltage sensor . The Umin

dial is a percentage of the Umax dial and is used to set the lower trip-point for the

voltage sensor . The timing dial is used to delay the transfer of the contacts, from

0–10 s, when a set point has been violated .

Application Data

Legacy Time Delay and

Sensor Relays

Definition

A time delay is a controlled period between the functioning of two events . A time

delay relay combines an electromechanical output relay and a control circuit . The

control circuit is composed of solid-state components that control the operation of

the relay and the timing range .

Typical time delay functions include:

On-Delay

Repeat Cycle (Starting Off)

Interval

Off-Delay

Retriggerable One-Shot

Repeat Cycle (Starting On)

Pulse Generator

One-Shot

On- and Off-Delay

Memory Latch

Each function is explained in the table on page 31 . Time delay relays offer a broad

choice of timing ranges from less than one second to many days . There are many

choices of timing adjustments from calibrated external knobs, DIP switches, thumb-

wheel switches, or a recessed potentiometer .

Principle of Operation

Time delay relays are simply control relays with a time delay built in . Their purpose

is to control an event based on time . The difference between relays and time delay

relays is

when

the output contacts open and close:

on a control relay, contacts change state when voltage is applied and removed

from the coil

on time delay relays, contacts change state before or after a pre-selected, timed

interval

Typically, time delay relays are initiated or triggered by one of two methods:

application of input voltage (On-Delay, Interval On, Flasher, Repeat Cycle,

Delayed Interval, and Interval/Flasher)

opening or closing of a trigger signal (Off-Delay, Single Shot, and Watchdog)

These trigger signals can be one of two designs:

a control switch (dry contact)—for example, limit switch, push button, float switch

voltage (commonly known as a power trigger)

Definitions

Input Voltage:

Control voltage applied to the input terminals (see the wiring

diagrams on page 31) . Depending on the function, input voltage either initiates

the unit or readies it to initiate when a trigger signal is applied .

Trigger Signal:

On certain timing functions, a trigger signal initiates the unit after

input voltage has been applied . As noted above, this trigger signal can either be a

control switch (dry contact switch) or a power trigger (voltage) .

Output (Load):

A time delay relay has an internal relay (usually mechanical) with

contacts that open and close to control the load . The contacts are represented by

the dotted lines in the wiring diagrams .

NOTE

: For the time delay relay to operate properly, voltage must be applied to

power the load being switched by the relay’s output contacts.

(A)

When the input voltage U is applied, time delay T begins . Relay

contact(s) R change state after the time delay is complete .

Contacts R return to their shelf state when input voltage U is

removed . A trigger switch is not used in this function .

(D)

Input voltage U must be applied continuously . When trigger

switch S is closed, relay contacts R change state . When trigger

switch S is opened, delay T begins . When delay T is complete,

contacts R return to their shelf state . If trigger switch S is closed

before time delay T is complete, then time is reset . When trigger

switch S is opened, the delay begins again, and relay contacts

R remain in their energized state . If input voltage U is removed,

then relay contacts R return to their shelf state .

(E)

Upon application of input voltage U, the relay is ready to accept

trigger signal S . Upon application of trigger signal S, relay

contacts R transfer, and preset time T begins . At the end of

preset time T, relay contacts R return to their normal condition—

unless trigger switch S is opened and closed before before

preset time T elapses . Continuous cycling of trigger switch S

at a rate faster than preset time T causes relay contacts R to

remain closed . If input voltage U is removed, relay contacts R

return to their shelf state .
