4.1 INTRODUCTION
The information in this chapter will enable you to
maintain the systems components ensuring smooth,
efficient operation of the motor. Preventative
maintenance of the equipment is also specified along
with periodic maintenance. Follow these practices
when operating your servo system.
4.2 PREVENTATIVE MAINTENANCE
Preventative maintenance can prevent situations that
will damage your equipment. Four types of
preventive maintenance are presented below.
Following each of the procedures can reduce
problems with and add life to your equipment
.
Preventative maintenance to
this equipment must be
performed by qualified
personnel familiar with the
construction, operation, and
hazards involved with the
application.
Electronic components in this
amplifier are static sensitive.
Use proper procedures when
handling component boards.
Preventative maintenance should be performed with
the BDS5 system out of operation and disconnected
from all sources of power.
4.2.1 Transient Voltages
All transient-producing
devices must be properly
suppressed.
Solid state controls of the BDS5 may be affected by
transient voltages. These voltages are in excess of the
specified voltage for any given circuit. When these
peak voltages occur, even for less than a second,
permanent damage to the BDS5 can occur.
In order to help avoid transient voltages that may
interfere with electronic circuit functions within the
PSR4/5 and BDS5, all switched inductive devices or
their wiring (solenoids, relay coils, starter coils, etc.)
must be suppressed. A 220 ohm, 1/2 watt resistor in
series with a 0.5 micro farad, 600 volt capacitor or
equivalent is suggested.
4.2.2 Surge Current
Excessive current greater than that of the specified
limits of the PSR4/5 and BDS5 can cause permanent
damage to the system. Current limiting means are
recommended to protect from these currents.
