BE1-79S Maintenance
6-1
NOTE
It is recommended that the relay be returned to the factory for repair and recalibration
due to the availability of factory or production quality test and calibration equipment as
well as parts. If returned, as a minimum, the entire relay cradle should be shipped as an
assembly, preferably in a case.
CAUTION
Removal and direct substitution of printed circuit boards or individual components does
not necessarily mean the relay will operate properly without further calibration or
verification. Always check/calibrate relay prior to replacing relay into the operating
system.
SECTION 6 • MAINTENANCE
GENERAL
The relay is a solid-state device and requires no preventive maintenance other than a periodic operational
check. The procedures in Section 5 of this manual provide an adequate check to verify proper operation of
the relay. If the relay fails to function, 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.
Due to the fact that most components are on conformally coated printed circuit boards, in-house replacement
of individual components may be difficult and should not be attempted unless appropriate equipment and
adequately trained personnel are available.
IN-HOUSE REPAIR
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.
The quality of replacement parts must be at least equal to the type in the original circuit.
