4.1 Frequent Checkpoints
4.2 Troubleshooting
The Micro-Tech 3101 Integrator is a solid-state device and should require very
little maintenance. The front panel can be wiped clean with a damp cloth, and if
necessary, a mild detergent (never use abrasive cleaners, especially on the
display window).
As a preventative measure, check to ensure all wires, plugs, and integrated
circuits are tight in their connectors. Also, keep the enclosure door tightly
closed to prevent dirt infiltration.
More often than not, a quick visual inspection leads to the source of trouble. If a
problem develops, check the following before proceeding to more specific
troubleshooting procedures:
• Check Power
1. Check the Line Voltage Selector Switches are set to the correct line
voltage
2. Check the fuse
3. Check that the power switch in ON and that power is supplied to the
unit.
• Check Connections
1. Check that all terminations are secure.
2. Check to ensure the Display Module and Keyboard connectors are
firmly seated in their connectors.
3. Check that all Jumpers are in their correct position.
This unit has built-in troubleshooting capabilities. A number of possible
problems are automatically detected and screen messages are displayed. Also,
refer to the Diagnostics Test Scrolls in MAIN MENU 3.
