3.2 Operator Interface
Your Thermo Scientific Belt Scale System is capable of accurate weighing,
provided it is installed, calibrated, operated, and maintained in complete
accordance with the instructions contained in this manual, along with our scale
frame installation manual.
Micro-Tech 3101 Integrator is a microcomputer-based instrument that accepts
and conditions speed and weight signals and provides visual and electrical
outputs for total weight and rate of flow. The Integrator produces a stable 10volt
DC excitation voltage capable of exciting up to six strain gauge load cells.
Sense lead terminations are also provided for six wire load cell cables.
Auto Zero Track enables the belt scale system to automatically zero itself during
extended periods when the conveyor belt is running empty. Auto Zero Track is
menu selectable because some installations may not desire this option. A “Z”
displays on the second line of the display to indicate the selection of this option.
Life expectancy of the RAM support battery is approximately ten years, if
power is not applied. Under normal operation where power is on continuously,
life expectancy is much longer.
Errors may occur during initial calibration and their reason must be corrected
during initial calibration. During normal operation, an error would most likely
indicate a failure in system or improper operation.
This section provides information about setting up and operating the Micro-Tech
3101. All operations are performed from the front panel of the electronic
enclosure.
• The operator interface, including all keys, indicators, and displays.
• Procedures for initial setup and calibration are provided. .
• Detailed operating procedures are also included. All operations are
performed from the front panel of the electronic enclosure.
The Micro-Tech 3101 has been adjusted, configured, and inspected at the
factory per the supplied customer data. Additional internal adjustments should
not be necessary for satisfactory performance. If adjustments become necessary,
refer to Chapter 4 Micro-Tech 3101 Maintenance.
