How to Test the Control Transformer (410-61): JVR Vac410
“The control transformer ensures that consistent power is transmitted throughout the electrical delivery system with reliability.”
Did your unit cease transferring power, and are you unsure what part is causing the break in the circuit? Today, we will go through the simple steps of testing what part is the culprit, as well as the importance of a control transformer in the unit’s power system. When you think your machine is down, it is likely as simple as finding what part needs replacing or repairing. Let’s begin!
What is a Control Transformer?
Function
The control transformer ensures that consistent power is transmitted throughout the electrical delivery system with reliability. Generally connected to the primary power source, the transformer accounts for regulating the primary power production. Initially, the primary power source produces more than enough power. Then the transformer works as a grounding system that has the ability to transform the current to only what the actual metal core circuit board needs. This is opposed to causing resistance or impedance, such as with a resistor.
They are often used in systems that require consistent power regulation for safety purposes, such as heating systems or other temperature and lighting control.
Design
During the manufacturing process, control transformers are purposefully made with materials to withstand the pressures it is expected to be under, considering their function. For example, epoxy resin is applied around the coils and acts as an effective insulator to protect from moisture. The development is to protect the circuits forming a straight line from the primary power source, leading to the rest of the circuit from overload.
Benefit
The transformer is an important component in manufacturing as it provides reliability, safety, and effective functionality of the power system.
When to Test the Control Transformer
If you are experiencing a power shortage, troubleshooting is necessary to find what connections are causing the problem. Although the control transformer could be the problem, it is rare when it experiences burnout. So the process will consist of what to test to identify which part of the electrical circuit is the problem. Instead of purchasing a part that may or may not be the problem, pull that voltmeter out of storage, and get to testing to locate that easy fix!
Tools Needed
#2 Phillips Screwdriver
Volt Meter / Multimeter Devices
Testing the Components of the Control Transformer System
About the Method
This method will test the quality of any features that need replacing.
Use the volt meter to check for power at the following locations. If the voltage is measured lower than expected, this traces the trouble spot of the circuit.
Steps
Accessing the Vac410 Interior
Remove the back panel of the Vac410 using the #2 Phillips to expose the interior of the unit for testing.
Identifying The Problem
Use the point of the Volt Meter / Multimeter pin wires. Test the following and use the video below for guidance if needed:
Main Breaker (+/- 210 V)
Voltage going into the transformer from the main breaker; located towards the front of the transformer (+/- 210 V)
Voltage leaving the control transformer; located at the two farthest points on the transformer (+/- 27 V)
Lastly, check the connection at the PC board (PCB) (+/- 27 V)
What’s Next?
Once you are finished troubleshooting, you should now know which part of the circuit requires repairing or replacing.
