Elite Masso Controller Not Powering On Test

This is for troubleshooting only. Do not perform this test unless otherwise instructed by support.

If your Elite Masso controller (screen) is not powering on, perform these tests.

All tests require a multimeter. They are inexpensive and readily available from places like Amazon, auto parts stores, and big box home stores. Here’s an example of one : https://amzn.to/3ADsXcS

  1. We will first check the fuses. We need to check the 1amp fuse on the front of the power box and the 10 amp fuse in the center back of the power box. If the fuses are blown, please replace them. If they are good, move on to step 2.

  2. Directly at the power box, Assuming you’re looking at it with the ‘clip’ for the cable at the top, black will go on the first pin on the left, and right will go on the second pin, right next to the black pin. The multimeter should be on the V selection, and it should be on DC volts (NOT AC volts). When doing this, it should read around 24v (ours was 23.8). If this is correct, move to step 3. If this is not around 24v, the issue lies in the power supply box and will need to be replaced.

  3. Now, we will test the (a) wire from the power box to the back of the Elite Masso Controller. With the (a) 5 pin cable plugged into the power supply, apply the same test as we previously did in #1 on the same two pins. Again, we should see around 24v. If you do not see around 24v the cable is bad and needs to be replaced. If you do see 24v, the cable is good and we can move on to step #4.

  4. We will not test voltage at the Elite Masso controller itself. This means we will need to open up the Masso controller. To do so, we need a 4mm hex key. Please fully remove the four bolts (orange arrows) and the swing open the top part towards the left side.

The MASSO Touch power supply connector is located at the top-right corner of the controller as seen in the picture below. MASSO Touch requires a power supply of 24 VDC with a minimum of 1.5 Amps output. Voltage not to exceed 25 VDC or be less than 23 VDC .

You will again perform the same test on the controller itself in the upper right side (see picture below). Place the red probe on the red PWR screw head in the upper right, and the black pin on the GND in the upper right to the left of the PWR red pins. The reading should be around 24v again.

If it is 24v then the Masso is getting the correct power.
If it is not 24v the Masso is not receiving the correct power. Please contact support@onefinitycnc.com for further troubleshooting.
