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.

SECTION 6

MAINTENANCE

GENERAL

BE1-25/79TR Sync-Check Reclosing Relays require no preventive maintenance other than clock battery
replacement (estimated 10 year life). If the relay fails to function properly and 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.

If in-house repair is to be attempted, replacement parts may be purchased locally. The quality of
replacement parts must be at least equal to that of the original components.

Where special components are involved, Basler Electric part numbers may be obtained from the number
stamped on the component or assembly. These parts may be ordered directly from Basler Electric.
When complete boards or assemblies are needed, the following information is required.

1. Relay part number.

2. Relay serial number.

3. Board or assembly.

a) Board or assembly name.
b) Part number.
c) Serial number.
d) Revision letter.

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.
