5.1 INTRODUCTION
The information in this chapter will enable you to
isolate and resolve common system hardware
problems. The troubleshooting methods in this
manual isolate each component from the system until
the problem is resolved.
5.2 FIELD SERVICEABILITY
CAUTION
Dangerous voltages exist in
this equipment. Also, motor
temperature may exceed 100
°
°°
°
C. Extreme caution should
be exercised when
troubleshooting this
equipment. Only qualified
individuals should attempt to
install, setup, operate, or
troubleshoot this equipment.
The BDS4 and PSR4/5 are designed to promote
minimum down time situations. Due to the compact
package size and to the fact that there are few user-
serviceable components on the modules, it is
recommended that they be replaced if they cease to
function properly. Return the modules, in their
entirety, to Industrial Drives for repair.
The only user-serviceable items on the PSR4/5 are
the output line fuses in the control DC voltage supply
and (in the 12 and 20 amp units) the shunt regulator
regeneration load resistor fuse.
CAUTION
To preserve the level of
protection for the product as
designed, replacement fuses
must be the exact same style
and ampere rating as those
originally installed.
The BDS4 modules may be interchanged, provided
the following guidelines are adhered to:
1. The BDS4 modules must be the same rating.
2. The motors being controlled must bear the
same model number.
3. In the event the motors have different model
numbers, the BDS4-COMP Board must bear
the model number of the motor being
controlled or the BDS4-COMP Board must be
altered, per TL (Test Limits Sheet) to make the
BDS4 compatible with the motor.
Before beginning the troubleshooting process,
consider the following points:
I. There are four (4) distinct areas within which a
fault may occur:
