BE1-25 Glossary
Output option
The third position of the Style Number defines the Output Relay options:
E)
Sync-Check NO Relay
F)
Sync-Check NO Relay with Push-to-Energize Output
G)
Sync-Check NO Relay and Voltage Monitor SPDT Relay. Not available if Voltage Monitor Option 2
is N or T.
H)
Sync-Check NO Relay and Voltage Monitor SPDT Relay with Push-to-Energize Output for both
relays. Not available if Voltage Monitor Option 2 is N or T.
Power supply
Projection mount
The eleventh position of the Style Chart selects the mounting option; Option 4-P is a projection mounted
relay
Qualified to IEEE C37.90.1-1989
Designed to meet or exceed industry standards for the specified American National Standards
Institute/Institute of Electrical and Electronics Engineers standard incorporating surge withstand capability
tests for relays and relay systems.
Semi-flush mount
The eleventh position of the Style Chart selects the mounting option; Option 4-F is a semi-flush mounted
relay
Sensing input range
The second position of the Style Number selects the Sensing Input Range:
1)
120 Vac, 1 - 99
°
Phase Angle Setting
9)
120 Vac, 1 - 99
°
Phase Angle Setting with Expandable Window
Note that when option 9 is selected, an Auxiliary or Status Output Option 3 is not available (a zero must be
in the tenth position of the Style Number).
Status output
The tenth position of the Style Number defines the Auxiliary or Status Outputs Option 3. A 6 in this
position designates a Power Supply Status Output.
Note that if the Expandable Window is selected (second position of the Style Number is 9), an Auxiliary or
Status Output is not available (a zero must be in the tenth position of the Style Number).
Synchronism-check
Synchronizing or synchronism-check devices operate when two ac circuits are within the desired limits of
frequency, phase angle, or voltage to permit or to cause the paralleling of these two circuits.
Time delay
Two thumbwheel switches on the front panel adjust the time delay. The fourth and fifth positions of the
Style Number define the option selected:
A6)
0.1 - 99 sec., adjustable from 1 to 99 sec when multiplier switch is in X1 position; 0.1 to 9.9 when
in X1.0 position
A7)
1 - 99 cycles, adjustable in 1-cycle increments. Multiplier switch is omitted with this option.
