6.5 Probe reset time

The probe reset timer on the PHC10-2 unit (later than version 5) is designed to be used where the touch

probe fails to remain seated following a head index move.

The timer enables the duration permitted for a probe reseat to be extended. It is designed to be used in

the event that a probe fails to rearm following a head index when using long extension bars.

6.6 Head connector and cables

Head cable numbers, descriptions and currents are set out in table 14.

NOTE: For maximum immunity from electrical noise, Renishaw recommends that:

1. Mating connectors must be metal bodied.

2. The overall cable screen is continuous and connected to the system ground on the user’s

equipment through the bodies of the connectors.

CAUTION: For correct system function, the maximum overall single core resistance between the

head and PHC10-2 should be 2.5W.

Table 15 shows the range of standard motorised head cables available from Renishaw.
