BE1-47N Maintenance

CAUTION
Substitution of printed circuit boards or individuals components does not necessarily
mean the relay will operate properly. Always test the relay before placing it in
operation.
SECTION 6 • MAINTENANCE
GENERAL
Basler relays are static devices which require no preventive maintenance other than a periodic operational
check. If the relay fails to function properly, contact the Customer Service Department of the Power Systems
Group, Basler Electric, for a return authorization number prior to shipping the relay.
Since most components are on conformally coated PC boards, in-house replacement of individual
components may be difficult and should not be attempted unless appropriate equipment and qualified
personnel are available. Accordingly, it is recommended that the relay be returned to the factory for repair
and recalibration. When returning the relay to the factory ship the entire relay cradle assembly, preferably
in its case.
IN-HOUSE REPAIR
Replacement parts can 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, the schematic, or the parts list. These parts may be ordered directly
from Basler Electric. Complete boards or assemblies may be ordered by supplying the following information.
1. 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 1 year intervals, power
is applied to the relay for a period of thirty minutes.
