THEORY OF OPERATION
• The part(s) to be detected are subjected to a high voltage electrostatic charge.
• The control unit circuitry measures the amount of energy required to charge the part during the charging time select-
ed, and compares that value with an installation specific pre-set “window”.
• If the reading falls within the end user determined pre-set setpoint, the part passes the ground test.
FEATURES AND BENEFITS
• Complete Monitoring System...consists of a control unit, ground probe, mounting bracket and low voltage cable.
• Meets Stringent Safety Requirements...FM approved for use in Class 1, Division 1 painting environments.
• Utilizes Various Input Signals for Part Detection...limit switch, photo-eye, PLC, robot signal or any 0 Volt ground
trigger detection process.
• Advanced Technology...allows user to adjust control unit for specific field calibration..
• User-Friendly Control Unit Software...allows end user to control start timer, scan duration timer and alarm outputs.
• Easy to Read Visual Indicators...users receive simple, precise feedback regarding ground path strength.
• Versatile Model...compatible with electrostatic systems, plastic or other non-metallic surfaces.
• Versatile Ungrounded Part Alert Notification...unit provides two contact closures that may be interfaced to a PLC,
horn or light for ungrounded part alert. Contact closures included are:
1. One FAULT indicator
2. One HIGH VOLTAGE ON indicator
