2.0 INSTALLATION
Select the location of the DP8 with due regard of safety and ease of operation. Keep it clear of moving parts
and coolant spray. Ensure that the natural ventilation around the digital sending unit (DSU) is not restricted.
To ensure correct operation of the DP8, it is recommended that the digital sending unit (DSU) is grounded to
the machine from the equipotential terminal. A ground strap is provided in the fitting kit. The strap should be
cut to a suitable length once the DSU had been fixed to the machine. A terminal is provided for crimping to
the ground strap. This operation should be conducted by a suitably qualified engineer. The machine must
also be grounded to a good earth point.
The DP8 can be mounted in two basic ways as shown in Figure 2.1
ack view)
Figure 2.1 - Mounting Procedures
2.1.1 Display and digital sending unit (DSU) mounted separately (Figure 2.1a)
The keypad/display unit incorporates an M10 tapped hole in the rear of the unit. The M10 hole can be used
to mount the display in any of the standard methods as shown in Figure 2.2. The M10 stud mount is
provided as standard. The swivel mount assembly (Part No. 294-37740), the DP8 mounting arm (Part No
294-40050) and the DSU mounting assembly (Part No 600-65590) are all optional items as detailed on the
price list.

INSTALLATION
The DSU is normally mounted on a vertical face on the rear of the machine. The DSU facilitates the fixing in
2, 3 or 4 point location. For metric applications drill and tap an M6 hole and locate the DSU by inserting one
of the M6 bolts provided. Ensure the DSU is level, mark the next location and drill and tap the second hole.
Repeat this process for the required number of fixing locations. For those customers requiring imperial
(Inch) fittings, repeat the above process substituting 1/4 inch UNC tapped hole and bolts.
Note: The fitting kit includes both the metric and imperial fittings. The metric fittings are zinc
coated whereas the imperial fittings are black
The DSU is connected to the keypad/display via a 3.5 metre 9 pin “D” type cable. The cable can only be
connected in one direction. Once connected, secure the cable at both ends using the slotted locking
screws.
Please note, as shown in Figure 2.1, the transducer and mains leads should be positioned underneath the
DSU to avoid any ingress of coolant.
2.1.2 Display and data sending unit (DSU) mounted together (Figure 2.1b)
An optional bracket (Part No 600-65590) is available to facilitate the mounting of the DSU directly to the
keypad/display. This assembly can be mounted using the standard M10 stud, the swivel mount assembly
(Part No 294-37740), the DP8 mounting arm (Part No 294-40050) . The last three items are optional and are
detailed on the price list.
The DSU is mounted to the optional bracket by four M6 bolts. These bolts are provided with the bracket
assembly.
The bracket kit includes a 300mm 9 pin “D” type cable. This cable is to be used to connect the DSU to the
keypad/display. The 3.5 metre cable is not needed in this configuration. The cable can only be connected in
one direction. Once the sockets are located in the DSU and the keypad/display secure the slotted locking
screws.

INSTALLATION
BEFORE CONNECTING THE ELECTRICAL SUPPLY TO THE DIGITAL SENDING UNIT (DSU), CHECK
THAT THE VOLTAGE SELECTOR SWITCH IS CORRECTLY SET. Figure 2.3 shows the position of this
switch.
The mains supply is connected through a detachable supply cord. The counter is supplied with a cord with a
right-angle connector. If another supply cord is used, it must have fitted a IEC320, 10A, EARTHED mains
connector with a cord rated for at least 10A.
The PROTECTIVE EARTH CIRCUIT of the mains supply MUST BE CONNECTED to the protective earth
terminal of the DSU through the supply cord.
The supply cord should be secured with cable ties to ensure that it cannot drop into a hazardous position,
ie. the floor or coolant tray, when disconnected from the DSU.
The supply cord must be routed away from moving parts, swarf, coolant or sources of heat.
If a mains plug is not already fitted to the supply cord or is of the wrong type, then a suitable EARTHED plug
should be used which complies with the relevant specifications for plugs and socket-outlets.
The mains supply fuse is a 20x5mm, type T0.5A, 250V. It is not to be replaced by the operator. If the fuse
blows it is a possible indication of some significant problem with the power source. Check the supply and
wiring carefully. If the fuse is replaced, the DSU must first be disconnected from the supply by the removal
of the IEC socket from the inlet. This connector is the primary disconnect device for the equipment and must
be accessible at all times. Do not position the equipment so that it is difficult to operate the disconnect
device.
NOTE: If the equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.

Caution. Refer to section 2.2 before connection to the mains supply.

Installation

The mains supply switch for the DP8 is mounted on the side of the DSU as shown in Figure 2.3.
When you switch on the DP8, the unit will automatically go through a brief self diagnostic routine.
During this routine, the name DP8 will be shown, then the software version number will be displayed and all
segments of the displays will be lit.
After this routine, the unit will display measurements and is ready for use.
The DP8 can be switched off via the mains switch on the DSU. Alternatively, the keypad/display can be
switched off by pressing the key. Please note that the DSU remains under power when the
key is pressed.
Figure 2.3 shows the connection sockets on the DSU. The DP8 is designed for use with Newall’s Spherosyn
and Microsyn transducers only. The transducers are connected to the DSU with Bleecon type connectors.
These connectors have a sliding sleeve that locks the connectors to their sockets.
Switch off the DSU before connecting or disconnecting the transducers. To fit the connectors into the
appropriate socket on the DSU, first align the connector and then push firmly in place. You should hear a
click confirming that the locking sleeve has engaged. To remove the connector, pull back on the connector
sleeve to disengage the locking mechanism.
The transducers and the display/keyboard are connected to the DSU at a separated extra low voltage
(SELV) level. Any additional interconnections must also be at SELV level.

4.0 SET-UP
The DP8 digital readout display is equipped with a Set-Up Routine. The routine enables the operator to
change factory settings in order to increase efficiency and productivity. If the factory defaults are suitable,
select the NORMAL option at the end of the Routine to restore the factory defaults.
Generally, the entire Set-Up Routine is performed only one time. Changing some parameters in Set-Up may
alter datums, SDMs, tool compensations and Digifind.
DO NOT RUN SET-UP IF YOU ARE NOT PREPARED TO LOSE THIS DATA.
Set-Up is enabled while the unit is running its initial self-test, just after powering on. Press the [ ON/OFF ] on
the face of the display as the self-test is running.
The Set-Up procedure makes use of a menu system. The main menu consists of a list of options that can be
customised for your use (See Table 1). You simply press the [ <<]and [ >>]keys to scroll through this list
until you reach the option you wish to change. To change the option when selected, press [ ENT].
To exit the Set-Up routine scroll through to the quit option and press [ENT ].
If the keypad/display has been switched off by pressing the [ ON/OFF ] key rather than switching off at the
mains, it is possible to enter the Set-Up routine by pressing the [ ABS/INC ] key followed by the [ ON/OFF ]
key.
