OPERATOR SAFETY
It is recommended that a fail safe SPINDLE ROTATION INHIBIT is built into the system.
This is one example, where the probe cable is plugged into a remote socket before
spindle rotation is enabled. This prevents spindle rotation when the probe is used.

Important :
1. SSR will be permanently damaged if ±50V dc is exceeded across socket pins 3 and 4
or the current exceeds 50mA. (i.e. ensure SSR supply is current limited).
2. Probe power supply must not exceed 30V dc.
3. Route cable away from high current sources. e.g. High current cables, axis drive motors,
three phase transformers etc.
