System compatibility
Compatibility description: ND2101G belongs to HEIDENHAIN Gage-Chek measurement family. Compatible with Solartron half-bridge displacement probes. Can work with Fives Giddings & Lewis PIC900 CNC heavy boring mill for on-machine inspection.
Function
Function description: ND2101G is single channel measurement evaluation unit manufactured by HEIDENHAIN. It receives analog displacement signal from half-bridge contact gauge probe, converts raw signal into accurate dimension reading and displays value on LCD panel. It can export measurement data via serial port for quality recording. The metal front panel is resistant to workshop dust and slight coolant splash. It is precision measurement electronic spare for heavy CNC boring mills.
Installation
Installation steps: Follow lockout/tagout safety procedure before installation. Cut off DC supply power. Install ND2101G into control cabinet panel. Connect half-bridge gauge probe to probe input port. Wire DC power and serial communication cable. Set probe parameters via front panel or software. Restore power, verify POWER and MEAS LED indicators, run probe calibration and measurement test.
Interface
Interface list: Probe input connector, DC power terminal, serial data port,on-board POWER / MEAS / FAULT LED indicators for HEIDENHAIN ND2101G 665 408-14.
Diagnostic
Troubleshooting: No measurement reading: Check 10~30V power supply, probe wiring breakage or connector pin damage. FAULT LED lit: Probe open circuit, signal out of range or internal hardware fault. Unstable reading: Poor probe contact, vibration interference or calibration drift.
