P&B Solid State Time Delay Terms and Definitions
A wide selection of various types of solid state time delay controls are
presented by Potter & Brumfield to meet the demands of commerce and
industry. Typical applications for P&B time delay relays include data
processing operations, machine tool, safety device control and alarm
circuit actuating. These diverse applications require a wide variety of time
delays such as: fixed time delay on “operate” or “release” which is
factory set and cannot be adjusted; resistor-adjustable time delay on
“operate“ which is adjustable with an external resistor; knob-adjustable
time delay on “operate” which has a calibrated knob built into the
assembly for ease of adjusting the time period. Each of the series of solid
state time delays presented here varies in its degree of accuracy, variety
available and cost to meet the requirements of every application.
Timing Variations - Any difference between the actual time delay of a
particular device and the nominal value specified for that device.
These variations are due to:
The terms used to define and specify time delay relay performance must
reflect one or more of these time variation factors with sufficient clarity
that both the manufacturer and the user may arrive at essentially the same
evaluation of device performance. To this end, the following terms and
definitions are used.
Specified Delay Time - The advertised (or print specified) time of the
delay function.
Actual Time, Standard Conditions (ATSC) - The actual delay time of
a given device operated at 25 C and nominal input voltage, with sufficient
“off” time of input voltage to permit full “short term” recovery of the
timing interval. For purposes of establishing a reference ATSC it is
recommended that the device be cycled @ 25 C, nominal voltage, with
input pulses of 1.3X specified delay time, with 1 sec. off times. The
resulting average of a group of consecutive time delay readings (excluding
the 1st, which had an unknown off time) may be used to determine ATSC.
Five cycles should be considered adequate for this determination.
The off time required for full “short term” recovery of the timing interval
will vary to some extent, depending on relay type, timing circuit imped-
ance (normally related to length of timing period), whether capacitor
shorting contacts are used, whether the previous timing cycle was
completed or interrupted during time out, and, if completed, the degree
to which the input control “on” time extended beyond actual time out.
In practice, off times used may vary from a minimum approaching the
release time of the output (50 to 200 ms typical, depending on the
particular design) to a second or more, with as much as 15% difference
in the resulting delay times. The greatest rate of change occurs as off
times become increasingly short, while the rate of change becomes
relatively negligible as increasingly long off times approach 1 second.
However, for very long off times (measured in hours), and additional
change in the first subsequent operation delay time may be experienced.

This additional change may be as much as 1-4% (depending again on time
delay type and design) and is usually obtained with off periods from 1-24
hours or more.
Repeatability - The percent variance of time within a group of consecu-
tive timing cycles, starting with the second operation, when the timing
device is operated under constant conditions (constant on-off times, input
voltage and temperature). The average of a series of five consecutive
operations, at any given set of conditions within specifications, will serve
as the reference for determining the variation of individual readings within
the group from the average. The maximum variation under such condi-
tions should not exceed the repeatability value specified. For conve-
nience, repeatability under standard conditions could be determined from
the test used to measure ATSC (see below, left).
Tolerance - The variation between the specified delay time and the
ATSC value, given in percent of the former.
Delta-Time - The percent timing change (from the ATSC value) for any
variation of voltage and/or temperature within specified limits. Tests for
this parameter would be essentially the same as described for ATSC,
except that any constant combination of specified voltage and tempera-
ture extremes may be used.
Recycle Time - The length of time the control voltage must be inter-
rupted, immediately following a timing interval, to produce a subsequent
delay of at least 95% of the reference delay under constant conditions of
input voltage and ambient temperature. The reference delay may be the
ATSC value determined under standard conditions (nominal voltage and
25 C); however, any constant voltage-temperature combination within
specifications may be used (must be the same voltage-temperature
combination as used for recycle checks).
Note: If control voltage is interrupted prior to completion of a timing
period, or at a time other than immediately following time out, the recycle
time value (off time) may produce a subsequently shorter timing period,
depending upon the particular design and when the interruption occurs
within the internal RC charging cycle.
Correspondingly, this subsequent time delay may be from 85% to 95%
of the reference actual delay as defined above.
Timing Cycle Interrupt “Transfer” - A momentary transfer (pickup and
dropout) of the switching relay contacts which may occur if the timing
cycle is interrupted. This phenomenon is inherent in CU series time
delays; and, depending on when the timing interval is interrupted, the
transfer duration may vary from zero to the release time value for that
device.
Release Time - The time required, after time out, for the output switch
to return to its normal, de-energized state when the control voltage is
removed. This will vary to some extent with the duration of “on” time
after actual time out and with temperature and voltage; the shortest
release time being obtained when control voltage is removed immedi-
ately following completion of a timing period under conditions of mini-
mum temperature and input voltage.
Transient Protection is provided so that the time delay will not be
damaged by a transient input.
Polarity Protection is provided internally to protect the time delay of DC
units from reversal of input voltage.
