3.0 Troubleshooting
The Greer Company is dedicated to the design and manufacture of electronic parts created to aid in
crane operation and in the protection of crane operators and associated personnel. The following
manual has been developed to assist Service Personnel in understanding, locating, and identifying
problems during the operation of the MicroGuard® RCI-514 Rated Capacity Limiter System. Do not use
this system without an operator who is knowledgeable in safety guidelines, crane capacity information,
and the crane manufacturer’s specifications. Use of calibration routines, without consultation with the
Greer Company, invalidates the warranty.
Where to go for help:
When field repairs cannot be made without replacement of a part, or when troubleshooting advice is
needed, contact:

responses that may help us to quickly and effectively solve your problem.
3.1 Overview & Preparation
This Troubleshooting Manual for the MicroGuard® RCI-514 Rated Capacity Limiter System provides
information and methods for isolating problems that may occur during operation of the System. Some of
these problems can be corrected in the field. Other problems may require replacement of parts or the
return of a part to the factory for servicing. Service personnel should have prior training and experience
in the procedure for operation and setup of this System.
The procedures in this manual are based on crane operation and function, when possible. A basic tool
kit consisting of wrenches and screwdrivers (flat and Phillips’ blades) is required to remove covers and
units for inspection. A digital multimeter (DMM) is required for certain troubleshooting procedures. The
DMM must be capable of measuring DC voltage with a range of 0 volts to ± 50 volts and resolution of
0.1 volts. Resistance range is 0 ohms to 2 megaohms. Low cost analog meters are not appropriate
because the input impedance of these meters can give false readings.
