Baldor GLC40, GLC60, GLC105, GLC45 manual Problems and Solutions, ‐1 General Troubleshooting Guide

Problems and Solutions

Some of the more common problems are listed in Table 5‐1. This information is intended to be a check or verification that simple causes can be located and fixed. It is not an exhaustive “how to” for all types of problems. Procedures that require in depth knowledge or skills (like flashing the field) should be referred to a qualified generator service center.

Table 5‐1 General Troubleshooting Guide

Problem	Possible Cause	Remedy
Engine cranks but will not start	No fuel.	Check that fuel valves are ON. Check fuel level in fuel tank.
	Low Oil Level	Low Oil Pressure Sutdown activated. Replensih oil to full.
	Restricted air flow.	Check/replace air filter.
	No spark.	Check/replace spark plug(s).
		Check that engine switch is in Start position.
	No engine speed during crank	The magnetic pickup must be correctly adjusted and operating.
Engine will not crank (electric start)	Dead battery.	Remove battery and trickle charge or replace with new battery.
		Never Jump Start.
	Emergency Stop LED is ON	Reset controller after an Emergency Stop.
Engine starts but will not run smoothly	Fuel or ignition problem	Refer to engine manual.
Engine overheats	Excessive load	Remove one or more electrical loads.
	Debris or dirt buildup on engine	Remove debris. Clean engine surfaces to allow cooling.
No output voltage	Ciruit Breaker tripped or failed.	Reset circuit breaker or replace if required.
	Internal failure of Alternator	Return to factory for repair.
Output voltage varies	Irregular speed (fixed speed mode)	Check engine for malfunction or load for fluctuation
	Fluctuating speed (fixed speed mode)	Stabilize load. The addition of a lamp load (resistance load) may
		compensate partially for load changes caused by intermittent motor
		operation. Do not overload.
	Loose terminal or load connections	Verify all connections and terminal tighness.

Low output voltage	Low engine speed
	Excessive load
	High resistance connections -
	connections will be warm or hot
	Internal failure of Alternator
	Low power factor

Verify engine RPM.

Check engine for malfunction or system for overload. Reduce load. Verify all connections and terminal tighness.

Return to factory for repair.

Reduce inductive (motor) load. Some AC motors use about the same current regardless of load. Do not use motors of greater horsepower rating than is necessary to move the mechanical load.

High output voltage	Excessive speed (fixed speed mode)	Check engine for malfunction. Verify engine RPM.
Electrical shock when frame is touched	Static charge.	Ground generator frame at local reference ground (see Section 3).
	Grounded armature or field coil.	Return to factory for repair
Mechanical noise	Internal failure of Alternator	Return to factory for repair
	Loose or misaligned coupling	Tighten; align coupling and alternator shaft to engine shaft.
