What’s a Control Box?
A control box is essentially utilized as a means for controlling connected heavy-duty equipment. Control boxes are utilized across a variety of industries, including medical applications, manufacturing, production, and other applications. Depending upon your particular needs and required functionality, customized software can be written to manage the various movements and processes of your equipment, whether in an individual, synchronized, or simultaneous manner.
Control Box Basics
Control boxes are used to govern a wide assortment of equipment, so sometimes it can be hard to define what’s included in each respective control box design. Nevertheless, there are common features found in most any control box. A control box typically comprises various instruments, including switches, knobs, buttons, and sliders. These instruments are directly connected to the equipment they are designed to govern, and they allow operators to start, stop, or adjust various equipment functions. A control box is essentially the physical interface which allows an operator to both control a particular piece of equipment, and also monitor how it’s performing in the process. To that end, control boxes are also able to receive data from various sensors, which is then used to help verify that the machinery is functioning correctly and in line with your expectations. All the controls are typically enclosed within the box in a secure manner to prevent any accidental contact or unauthorized access to the controls.
Troubleshooting a Control Box
Unless you’re familiar with the inner workings of a control box and are also comfortable testing various aspects of electrical equipment, specific troubleshooting procedures are best left to a trained professional – like those you’ll find at AES! Here are some tests we can perform to thoroughly diagnose your control box:
Measure voltage at the pressure switch
The voltage at L1 and L2 of your pressure switch should be +/- 10% of the motor rating. Excessive voltage drop can come from loose connections, bad contacts, ground faults, or an inadequate power supply. Any relay chatter can also be caused by low voltage or ground faults.
Measure voltage at the control panel
Same as the voltage at the pressure switch, your control panel voltage reading should be +/- 10% of the motor rating.
Check the overloads
Testing the overloads entails checking every solder point with an ohmmeter. We’re looking for any readings less than 0.5. A zero reading indicates that the overloads are tripped; in that case, we’ll reset the overloads and then retest.
Check the run and start capacitors
We remove the capacitors, and then attach the ohmmeter leads to the terminals. The reading on the ohmmeter should initially fall, and then climb towards 1 if the capacitor is good.
Potential (voltage) relay coil test
We remove the relay, and attach the ohmmeter leads to connections #2 & #5. A good coil should measure between 4.5 and 7.0.
Potential (voltage) relay contact test
Next, we attach the leads to connections #1 & #2. A correct reading for a good contact should register zero ohms.
Line contactor coil test
We remove the line contactor, and then attach the ohmmeter leads to the contactor coil terminals. A correct meter reading for a good coil should register between 1.8 and 14.0.
Line contactor test
Attach the ohmmeter leads to either L1 & T1 or L2 & T2. Once the contacts are manually closed, a correct meter reading should display zero ohms.
