BE1-BPR General Information
1-7
Real Time Clock Resolution
±1 second
Real Time Clock Stability
±30 ppm typical
Real Time Clock Accuracy
Relays with IRIG-B, ±1 millisecond. If IRIG-B signal is lost, accuracy
defaults to the real time clock stability.
BESTLogic Operate Time
Operate time is 1.4 milliseconds typical, 2.8 milliseconds maximum. (at
60 hertz)
Output Relays
Any output contact closed by the relay logic will be held closed for 200 to
250 milliseconds even if the initial cause of the closing goes away. After
200 to 250 milliseconds, the relay close time is determined by the state of
the relay logic. This minimum hold time may be disabled by using the
PHOLD command.
Factory preset output
contact configuration:
ALARM Output:
Output 1 - 5:
Output contacts close when ALARM logic (LOA) is true or power is lost.
Output contacts close when the corresponding logic equation (LO1 - LO5)
is true.
Output Relay Pickup Time
ALARM:
Output 1:
Output 2, 3, 4, 5:
8 milliseconds typical, 10 milliseconds maximum.
¼ cycle (4.2 milliseconds) maximum.
8 milliseconds typical, 10 milliseconds maximum.
Output Contact Rating
Resistive:
120/240 Vac
250 Vdc
Inductive:
120/240 Vac
125/250 Vdc
Output contacts are rated as follows:
Make and carry 30 amperes for 0.2 second, carry 7 amperes continuously,
and break 7 amperes.
Make and carry 30 amperes for 0.2 seconds, carry 7 amperes continuously,
and break 0.3 amperes.
Make and carry 30 amperes for 0.2 seconds, carry 7 amperes continuously,
and break 0.3 amperes. (L/R=0.04).
Display
Two lines by 16 character LCD alphanumeric display with LED backlight.
Targets/Indicators
POWER:
CLOCK:
50PU:
ALARM:
TARGET:
Five diagnostic LEDs are provided.
Green LED (normally ON) to indicate power supply is operating.
Green LED (normally OFF) turns ON to indicate that the clock needs to be
set.
Red LED (normally OFF) turns ON to indicate one or more of the inputs has
exceeded the pickup level(s).
Red LED (normally OFF) turns ON to indicate problems. Output A (ALARM)
de-energizes (closes) when ALARM LED is ON.
Red LED (normally OFF) turns ON if one or more of the relay outputs has
been energized. (If programmed by the PTARGET command.)
Keypad
Five keys are used to access information on the display and enter
settings.
Communications
Connectors:
Baud Rate:
Buffer Size:
Only one communication port can be active at any time.
Front panel - RS-232, 9 pin, female, D-sub DCE
Rear panel - RS-232, 9 pin, female, D-sub DCE; RS-485, 3 position
terminal block
300, 600, 1200, 2400, 4800, 9600, and 19.2 k (19,200)
