SSAC HRDR Series Data Sheet

HRDR SeriesTimer - Recycling

Connection:

L1 N/L2

NO = Normally Open
S1 = Reset Switch
C = Common, Transfer Contact
L = Load

Terminals 4 & 5 and/or 7 & 8 are only included
on externally adjustable units.
Relay contacts are non-isolated. RT is included
when external adjustment is ordered. Terminal 6 is
included when Bypass/Reset is selected.

The HRDR Series combines an electromechanical
relay and microcontroller timing circuitry. It offers
12 to 230V operation in ve ranges and factory
fixed, onboard or externally adjustable time
delays with a repeat accuracy of ±0.5%. The high
switching capacity of the output contacts allow
for direct control of heavy loads like compressors,
pumps, motors, heaters and lighting. A bypass/
reset switch option allows operator to interrupt
normal recycling sequence and energize output
relay. An excellent choice for OEM applications.

Operation (Recycling with Reset Switch):

Upon application of input voltage, the ON time T1 begins
and output relay energizes. At the end of the ON time,
the output relay de-energizes and the OFF time T2 begins.
At the end of the OFF time, the output relay energizes
and the cycle repeats as long as input voltage is applied.
Some recycling timers have the OFF time as the rst delay.
Reset: Removing input voltage resets output and time
delays, and returns sequence to the rst delay.
Bypass/Reset Switch: Closing the normally open bypass/
reset switch energizes the output relay and resets the time
delays. Opening the switch restarts recycling operation
with the rst delay.

Appendix A - Timer Functions

Selecting a Timer’s Function

Selecting one of the ve most common timing functions can be as easy as answering three questions on the chart below. If you have trouble answering
these questions, try drawing a connection diagram that shows how the timer and load are connected. Time diagrams and written descriptions of the
ve most popular functions, plus other common functions. Instantaneous contacts, accumulation, pause timing functions, and ashing LED’s are
included in some units to expand the versatility of the timer. These expanded operations are explained on the product’s catalog page. Time diagrams
are used on these pages along with text and international symbols for functions.

Function Selection Guide

Selection Questions

1) The timing starts when the
initiate (starting) contacts are:

A) Closed B) Opened

2) What is the status of the output
(or load) during timing:

A) On B) Off C) On/Off

3) Will the load de-energize
(or remain de-energized)
if the initiate (starting) contacts
are opened during timing:

A) Yes B) No

Understanding Time Diagrams

Time diagrams are used to show the relative operation of switches,
controls, and loads as time progresses. Time begins at the rst vertical
boundary. There may be a line indicating the start of the operation or it
may just begin with the transition of the device that starts the operation.
Each row in the time diagram represents a separate component.
These rows will be labeled with the name of the device or its terminal
connection numbers. In a bistable or digital system, the switches,
controls, or loads can only be ON or OFF. The time lines are drawn
to represent these two possible conditions. Vertical lines are used to
dene important starting or ending points in the operation.

The example to the right is the most common type of time diagram
in use in North America. It shows the energizing of loads, and the
closing of switches and contacts by an ascending vertical transition of
the time line. Opening switches or contacts or de-energizing loads are
represented by descending vertical transitions.

®

Delay-on-Make: (ProgramaCube

(ON-delay, Delay on Operate, On Delay, Operate Delay, Delay On, Prepurge Delay)
OPERATION: Upon application of input voltage, the time delay begins. The output (relay or solid state)
is de-energized before and during the time delay. At the end of the time delay, the output energizes
and remains energized until input voltage is removed.
RESET: Removing input voltage resets the time delay and output.
See: HRPS, KRPS, KSPS, KSPU, NHPS, NHPU, TDM, TRDU

Function M)

Extra Functions Included in Some Delay-on-Make (DOM) Timers:

®

Accumulating Time Delay Feature: (ProgramaCube

Some DOM timers allow the time delay to be stopped and held and then resumed by opening and closing
an external switch. The total time delay, TD is the sum of the accumulated partial time delays, “t”.
See: KRPD, KRPS, HRPS, NHPS, KSPD, KSPS, TRDU

= Recycling - Unequal Times; Pulse Generator

= Recycling - Unequal Times Starting with ON or OFF

= Delay-on-Make & Interval; Single Pulse Generator

Delay-on-Make (ON-delay)

Instantaneous Contacts:

Some DOM timers have a set of instantaneous contacts in addition to the delayed contacts. Instantaneous
contacts energize when input voltage is applied and remain until voltage is removed.

Delay-on-Make, Normally Closed Output:

All relay output delay-on-make timers with normally closed contacts include this function. (See Delay­on-Make NC Contacts) This function is also available in solid-state output timers. The solid-state output
energizes when input voltage is applied. The time delay begins when an optional initiate switch S1 is closed
(timing starts when voltage is applied if S1 is not used). The output de-energizes at the end of the time delay.
Reset: Opening S1 resets the time delay and the output immediately energizes (or remains energized).
Removing input voltage resets the time delay and de-energizes the output.
See: KSD4, THD4, TS4, TSD4

®

Interval: (ProgramaCube

(Impulse-ON, Single Pulse on Operate, On Interval, Interval On, Pulse Shaping, Bypass Timing)
OPERATION: Upon application of input voltage, the time delay begins. The output (relay or solid
state) energizes during the time delay. At the end of time delay the output de-energizes and remains
de-energized until input voltage is removed.
RESET: Removing input voltage resets the time delay and output.
See: HRPS, KRPS, KSPS, KSPU, NHPS, NHPU, TDI, TSD2

Function I)

Extra Functions Included on Some Interval Timers:

Instantaneous Contacts:

Some Interval timers have a set of intantaneous contacts in addition to the delayed contacts.
Intantaneous contacts energize when input voltage is applied and remain until voltage is removed.
