BE1-32R, BE1-32R O/U
7
SPECIFICATIONS
(continued)
Each model, BE1-32R or BE1-32 O/U is capable of
instantaneous trip, definite time delay trip, or an inverse
time delayed trip as defined and selected by the Style
Chart.
Instantaneous response time of the relay is within 80
ms (60 Hz) or 100 ms (50 Hz) for a real power magni-
tude of 2 times the setting.
The definite time delay is adjustable over the ranges of
0.1 to 9.9 seconds and 01 to 99 seconds. Selection of
the ranges is accomplished by a front-panel multiplier
switch which selects either 0.1 or 1.0 as a multiplier of
the front panel Time Dial thumbwheel switch. (A Time
Dial setting of 00 enables instantaneous operation.)
Definite timing accuracy is ±5% of the setting or 50 ms,
whichever is greater.
Inverse time delayed trip is available for the overpower
function only. The inverse time delay curve is adjust-
able from 01 to 99 by means of a front-panel
thumbwheel switch. Incrementing the thumbwheel
switch moves the inverse curve along the vertical axis.
(See Figure 12 for Inverse Time Characteristics.) A
Time Dial setting of 00 enables instantaneous opera-
tion. Inverse time is accurate to within ±5% of the
published curve or 50 ms, whichever is greater.
POWER SUPPLY STATUS OUTPUT (OPTIONAL)
The power supply status output relay is energized and
its NC output contact is opened when power is applied
to the relay. Normal internal relay operating voltage
maintains the power supply status output relay continu-
ously energized with its output contact open. If the
power supply output voltage falls below the require-
ments of proper operation, the power supply output
relay is deenergized, closing the NC output contact.
