In industries that have high production costs occurred when the “down time” is beginning a disorder that causes a great loss per unit time. Therefore, there must be personnel were skilled troubleshooting. Troubleshooting is a process of detecting and diagnosing all possibilities that may cause a production of equipment can not function properly.
Of proven field experience, that many engineers are able to work on the panel wiring is good but can not do much when he made the control circuit is not functioning due to interference.
A. troubleshooting skills.
Troubleshooting problems is not only a purely technical issue but also contains elements of art. To be a technician troubleshooting a skilled troubleshooter then one must have certain requirements, among others:
- Having a deep understanding of the normal operation of the equipment at hand and in addition it should also have knowledge of other relevant areas of expertise, such as knowledge of mechanical, electrical and use of electrical measuring instruments.
- And no less important is the experience.
B. General Procedure.
Troubleshooting work is complicated, full of variety and very complex. But this work can be easy and simple when implemented systematically by following the applicable procedures. This procedure will help the technician troubleshooter find fault location accurately and quickly. There are 6 stages of work to be done by a troubleshooter at the time of troubleshooting, namely:
1. Recognize complaints or disorders that arise.
2. Conduct a series of examinations.
3. Analyze the results of the examination.
4. Determine the cause of the disorder and how to overcome them.
5. Fixing the damage.
6. Perform testing (testing).
In general, electrical circuit here can be divided into two parts:
- Power circuit
- Control circuit
The first check should be done on the power circuit. Furthermore, if the power circuit work, do check on the control circuit.
Checking the power circuit:
- The input power to the circuit and its perfection.
- Check that the function of the protective device.
- Check cable continuity in vision.
- Check for signs of burning on the equipment.
Checking the control circuit:
- The first power to the control circuit.
- Check that the function of the relays, timers and switches.
- Check cable continuity in vision.
- Check the connection wire and terminal circuit.
- Check logic operations sekuense switching contactors.
- Check the setting of the duration of time.
