Agilent 5DX Service Guide 3-5
5DX Series 3 Safety Interlock Controller
For troubleshooting purposes, there are two test points on the Safety Interlock
Controller. TP1 is for Chain 1 and TP2 is for Chain 2. Connect a voltmeter, set to
beep on a voltage level, from the appropriate test point to the test point’s ground. If
an audible voltmeter is unavailable, it will take two persons to troubleshoot the
interlocks, one to check and operate the interlocks and another to monitor voltage
levels.
