MAINTENANCE
GENERAL
BE1-25 Sync-Check Relay requires no preventive maintenance other than a periodic operational test (see
Section 5, Operational Test Procedure). If factory repair is desired, contact the Customer Service
Department of the Power Systems Group, Basler Electric, for a return authorization number prior to
shipping.
IN-HOUSE REPAIR
In-house replacement of individual components may be difficult and should not be attempted unless
appropriate equipment and qualified personnel are available.
CAUTION
Substitution of printed circuit boards or individual components does not necessarily mean
the relay will operate properly. Always test the relay before placing it in operation.
Replacement parts may be purchased locally. The quality of replacement parts must be at least equal to
that of the original components. When complete boards or assemblies are needed, the following
information is required.
1.
Relay model and Style Number
2.
Relay serial number
3.
Board or assembly
a) Part number
b) Serial number
c) Revision letter
4.
The name of the board or assembly.
STORAGE
This protective relay contains aluminum electrolytic capacitors which generally have a life expectancy in
excess of 10 years at storage temperatures less than 40
°
C. Typically, the life expectancy of the capacitor
is cut in half for every 10
°
C rise in temperature. Storage life can be extended if, at one-year intervals,
power is applied to the relay for a period of thirty minutes.
TEST PLUG
CAUTION
When the Voltage Monitor option is controlled by external contacts (option 2-C, 2-U, or 2-
V), do not replace the upper connection plug with a test plug unless the test plug is
equipped with proper adapter (see Figure 5-1). If the correct Test Plug Adapter is not
readily available, an alternative procedure is described at the end of this section.
Test plugs (Basler P/N 10095 or GE model XLA12A) provide a quick, easy method of testing relays
without removing them from their case. Test plugs are simply substituted for the connection plugs. This
provides access to the external stud connections as well as to the internal circuitry.
