4 Safety GB Warnings In all applications involving the use of machine tools or CMMs, eye protection is recommended. There are normally no userserviceable parts inside Renishaw mainspowered units. Return defective units to an authorised Renishaw customer service centre. Replace blown fuses with new components of the same type. Refer to the safety information in the relevant product documentation. For instructions regarding the safe cleaning of Renishaw products, refer to the maintenance information in the relevant product documentation. Remove power before performing any maintenance operations. Always allow sufficient time for electrical change to dissipate from electrical components before handing. Observe antistatic handling precautions, including the use of earth straps with plugin cards. Refer to the machine supplier's operating instructions. It is the machine supplier's responsibility to ensure that the user is made aware of any hazards involved in operation, including those mentioned in Renishaw product documentation, and to ensure that adequate guards and safety interlocks are provided. Under certain circumstances the probe signal may falsely indicate a probeseated condition. Do not rely on probe signals to stop machine movement. The expected method of providing an emergency stop for Renishaw products is to remove power. Care of equipment Renishaw probes and associated systems are precision tools used for obtaining precise measurements and must therefore be treated with care.

51 PD and PD interface modules 9 PD and PD interface modules. The PI interface used PD and PD modules that are now obsolete, they were used as follows: PD For decoupling the SYNC output signal allowing parallel connection of Renishaw interfaces. It was used in systems requiring an interface selector (IS). The PD was installed between the interface, controller and the PICS cables by direct connection to the PICS output on the rear of the PI interface. PD For selectively filtering the application of the PROBE DAMPING signal input to the TPM probe system. It was used in installations where PROBE DAMPING could be applied while the probe was still in contact with the part. When installed, the PD only allowed the damping signal (PICS pin PDAMP) to enter the system when a PROBE SEATED condition was indicated on the PROBE STATUS line (PICS pin SYNC). With the exception of DAMPING, all PICS signals were unaffected. The PD was fitted between the PI and the PICS cable by direct connection to the PICS output connector of the PI interface (early versions only). IMPORTANT: Where a PD is fitted, the PD must be furthest from the unit. Applications used are OP, PCM, PI and IS (very early units only) and ACC when TP00 and PI 00 are used. The PD and PD modules are now obsolete and have been incorporated in the PI interface.

Baud rate Switch Brown ON ON ON ON OFF OFF OFF OFF Red ON ON OFF OFF ON ON OFF OFF Orange ON OFF ON OFF ON OFF ON OFF NOTE: Switch functions are ON = UP and OFF = DOWN Some CMM s use a head present indication that is enabled by an SW switch or wire link on the PHC9 Mk RS version controller board. Access to this is obtained by removing the PSU9 power supply and then separating the PHC9 Mk controller casing. The SW switch or wire link is located on the top, right, rear face of the controller board.! CAUTION: When refitting the PSU9 power supply, ensure that the voltage selector switch is set to the correct value as failure to do so will damage the controller.

115 PHS servo positioning head PHS servo positioning head. The PHS servo positioning head system currently uses an ISA type control card fitted to either the CMM controller or PC. This card provides axis control but does not condition the system probe signals. A suitable probe interface must be used with this system. This section provides switch settings, a schematic diagram, signal descriptions and pin numbers for the PHS control card, PHS head and cables used with it. As the PHS can also be mounted on KM or KM kinematic mounts, details are provided for signals and pin numbers of these too.! WARNING: Always disconnect mains power to the PHS, cables or control card before carrying out service actions or changing switch settings. ATTENTION: The PHS control card contains static sensitive components. Observe antistatic handling precautions, including the use of earth straps during handling and installation. NOTE: The maximum permissible cable length is 0 m. It is recommended that the resistance of the power cable should typically be Ω but should not exceed Ω total loop resistance as a thermal fuse and switch mode power supply are configured to monitor the correct voltage to the head. High cable resistance may trigger the thermal fuse. This is usually evident by the symptom of brief power up, approximately or seconds. Where the head LED lights before extinguishing. Exchanging heads may appear to solve the problem however this is usually due to electrical tolerance differences between systems.

Alternatively, standalone mode can be enabled to allow the controller to operate in isolation using timebased commands derived from the order in which the rack port lids are operated. Regardless of the age of units, communication type or whether standalone mode is being used, a common command set language is used to talk between the autochange controller and the rack. ACC is now obsolete and was the original version, support is only available by upgrade to ACC. ACC is also obsolete and was the main production version with support available by upgrade only to the ACC. ACC is the current version controller. Integration of autochange systems should be done by a competent CMM service provider or the machine manufacturer. Original flat foil screened rack cables connecting the ACC to the ACR rack are also obsolete and they have been superseded by round cables with a braided screen.

Select your output by setting the elements of switches SW and SW (elements and on each switch) as shown in the table. Switch SW, element (orange) is don t care.. Select buzzer ON or OFF by switching element (yellow) on switch SW: Buzzer ON = Buzzer OFF = 0

128 ACC autochange controller 0.. ACC RS serial communication switches To enable RS serial communications, set switch (yellow) on IC to 0, then set switches, and to the required Baud rate shown below: Baud rate Brown Switch Red Orange INVALID 0.. ACC IEEE parallel communication switches To enable IEEE parallel communications the device address and parallel poll bit must be set on the microcomputer board. Then set switch (Yellow) on IC to and set the switches on IC to the required device address (0 to ) and parallel poll bit ( to ) as shown below. PARALLE L POLL BIT Grey Purple Blue DEVICE ADDRESS Green Yellow Orange Red Brown

129 ACC autochange controller 0.. ACC standalone mode switches Standalone mode operation allows the ACR rack to be operated without any communications link between the ACC and the CMM controller or PC. It relies upon the order in which the rack infrared light beams are broken as ports open or close as a probe is parked or pickedup. Different timedelays can be set for the ACR rack operation using the DIL switches. 0.. Standalone mode selection Standalone mode is selected using the four element switches on IC of the microprocessor board. The switch selections are as follows: Switch Position ON (UP) ON (UP) ON (UP) OFF (DOWN) 0.. Standalone time delay The delaytime is selected using the eight element switches on IC on the microprocessor board. The five switches are used to set the delaytime in 0. second steps and are binary coded. Switch Position Delay time ON (UP) ON (UP) ON (UP) ON (UP) ON (UP) 0. seconds 0. seconds 0. seconds. seconds. seconds Example: Switch (0. sec) and switch (0. sec) set to ON (UP) would equal.0 seconds.

130 ACC autochange controller 0. ACC controller connectors 0.. SK probe head connector The SK probe head connector is a pin Dtype socket, the signal descriptions and pin numbers are detailed below: 9 0 I/F LED K, probe LED cathode T probe contact I/F LED A, probe LED anode 0 V, cable screen T probe contact SK 0.. PL RS serial communication connector The PL RS serial communication connector is a pin Dtype plug. Signal descriptions and pin numbers are shown below: 0 V screen (ACC chassis) TXD transmit data, output from ACC RXD receive data, input to ACC RTS ready to send, output from ACC CTS clear to send, input to ACC 0 V signal common to ACC chassis PL NOTE: a) RTS is active (high) when a message is waiting to be transmitted. It is cleared after the last byte of the message has been transmitted. b) CTS is monitored by the ACC and transmission is halted if CTS goes inactive (low), it is resumed when it goes active (high). CTS MUST be linked to RTS if not used by the CMM.
