What to do next After you have finished installing the air preparation pack, install the NC4+ Blue system (see page 3-4, “Installing the NC4+ Blue system”, for further information). Do not switch on the air supply or set the air pressure until the NC4+ Blue unit and NCi-6 interface unit have been installed and electrical power has been supplied .

MicroHole and the maximum signal is obtained on the voltmeter or set-up tool . Check that either: • the voltmeter reading is between 1 .0 V and 7 .0 V, or • the set-up tool reading is between 1 .0 and 7 .0 . www.renishaw.com/nc4...
At the transmitter head, tighten the pitch and rotation locking screws to 2 Nm (1.48 lbf.ft). Check that the reading is still between 1.0 V and 7.0 V using the same device (voltmeter or set-up tool) used in step 7. 10 .
NC4 set-up tool Introduction The NC4 set-up tool (Renishaw part no. A-4114-8000, sold separately) is a battery-operated device that is used to provide a visual indication of the signal strength at the NC4+ Blue unit receiver head . The signal strength is shown on a numerical display .
Using the set-up tool The set-up tool numerical display provides a correct reading only when the NCi-6 interface unit is in the set-up mode – that is, when the NC set-up switch (SW1-2) is set to ‘On’. Check that the NC4+ Blue receiver head is clean and free of swarf . Push the set-up tool onto the top of the receiver head and rotate it so that the display is facing you .
Typically, this specification can be provided by a cell containing Lithium-thionyl chloride (3.6 V). This is recommended for maximum battery life. A Lithium-thionyl chloride (3.6 V) battery will last the equivalent of 700 hours’ continuous operation .

Status LED function The status LEDs on the NC4+ Blue transmitter and receiver heads indicate to the user the status of the unit . The LEDs mimic each other . Status LED (on transmitter and receiver heads) Colours shown by the LEDs vary depending upon the mode of operation of the NCi-6 interface unit . When the NCi-6 NC set-up switch SW1-2 is set to ‘On’, the status LEDs will rapidly flash code which is used by the NC4 set-up tool .
