AMP MATE TROUBLE SHOOTING
Read this if you are experiencing frequent jams
Matt Findlay - 26/12/2018
We have noticed that some AMP MATE users have been experiencing some issues with the amp mate jamming in the downward position. This problem is usually caused by one of two things, a lack of grounding between the sensor and its bracket or the in adequate shielding against the EMF generated by the case hoppers.
Both of these problems can be resolved with the following modifications. These can either be purchased at your local electronics store if you want them sooner or we can ship them out with a delivery time of 7-10 days. Just send us an email in the contact us section to enquirer.
Grounding the sensor:
Step 1: Unplug the sensor from the main circuit board and remove the three bolts which attach the sensor bracket to the side panel. You can then remove the sensor and its bracket from the main amp mate assembly.
If you have received a replacement sensor from us, simply re install the sensor in reverse. Make sure that it is plugged in correctly with all 6 pins being inserted into the plug.
Step 2: If doing the modification yourself you will need some hook up wire (0.2-0.5mm), some crimp terminal rings and a crimp tool and a soldering iron.
Step 3: Make up the wire with both ends stripped and with one end crimped with the ring. the wire needs to be at least 20mm long. Tin the other end of the wire.
Step 4: Install the crimped end underneath the nut pictured below and so that the wire can reach the pin as shown.
Step 5: Solder the wire to the pin shown below:
Step 6: Reinstall the sensor in the reverse order of step 1 and your jam issue should be resolved.
Shielding the USB cable:
If your unit is jamming when the case hopper is activated this will solve the issue:
Step 1: We use a ferrite clamp on filter to solve this problem as shown below. The part can be purchased directly from here
or we can send you one direct which will take 7-10 days.
Step 2: With the filter open, wind the usb cable round it two times as shown below and then snap it closed. This should stop the electrical noise of the hoppers from interfering with the coms between the amp and the amp mate.
