BE1-32R, -32 O/U MAINTENANCE
6-1
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
BE1-32R, -32 O/U Directional Power Relays require no preventive maintenance other than a periodic operational
test (refer to Section 5 for test procedures). 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.
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, component values may be obtained from the schematics or the parts list
of the Service Manual. 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, the schematic, or parts list. These parts may be ordered directly from
Basler Electric. 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
Test plugs (Basler part number 10095 or G.E. part number XLA12A1) 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.
Test plugs consist of black and red phenolic moldings with twenty electrically separated contact fingers
connected to ten coaxial binding posts. Fingers on the black side are connected to the inner binding posts (black
thumb nuts) and tap into the relay internal circuitry. Fingers on the red side of the test plug are connected to the
outer binding posts (red thumb nuts) and also connect to the relay case terminals.
When testing circuits connected to the bottom set of case terminals, the test plug is inserted with the numbers
1 through 10 facing up. Similarly, when using the test plug in the upper part of the relay, the numbers 11 through
20 are faceup. It is impossible, due to the construction of the test plug, to insert it with the wrong orientation.
