PACE Pressure Controller User Manual
1 Description
1.1Introduction
The PACE5000 single-channel and PACE6000 single/dual-channel, Pressure Automated Calibration Equipment measures and controls pneumatic pressures and displays, on a touch-screen, the pressure measurement and controller status. The touch-screen enables selections and settings in both measure and control modes. The instrument can be operated remotely through communication interfaces.
Figure 1-1 PACE5000 General view
Figure 1-2 PACE6000 General view
The rear of the instrument houses all the electrical and pneumatic output and input connections. The electrical connections provide an a.c. power supply, serial and parallel communication interfaces, d.c. output and logic input and output. The system pneumatic controller module contains a positive and negative pressure supply port, an output port, vent port and reference port.

2.1Packaging
On receipt of the PACE5000 or PACE6000 check the contents of the packaging against the following list:
Packaging List
i)PACE5000 or PACE6000 Pressure Controller.
ii)Cable, power supply.
iii)User guide and CD (UD-0001) containing the full documentation suite.
iv)Pneumatic Control Module blanking plate (keep this plate for future use).
CAUTIONS:
1.AFTER REMOVING A CONTROL MODULE, USE A BLANKING PLATE TO KEEP THE FLOW OF COOLING AIR.
2.AFTER UNPACKING AN INSTRUMENT THAT HAS BEEN IN COLD CONDITIONS ALLOW TIME TO STABILISE AND ANY CONDENSATION TO EVAPORATE.
2.2Packaging for Storage or Transportation
To store the instrument or to return the instrument* for calibration or repair carry out the following procedures:
1.Pack the instrument as detailed in section 6.8, Reference and Specification.
2.Return the instrument for calibration or repair complete the return goods procedure detailed in section 6.8, Reference and Specification.
*This procedure also applies to the pressure control module as a separate item.
2.3Preparation for Use
The instrument can be used as a:
•Free-standing instrument positioned on a horizontal surface.
•Rack-mounted in a standard 19 inch rack using the rack-mount accessory option kit (refer to section 2.5).
For free-standing instruments, use the two front feet on the base to elevate the instrument to provide a better viewing angle.
Note: The cooling air outlet on the underside of the instrument must not be obstructed. Allow a free flow of air around the instrument, especially at high ambient temperatures.

Pressure supply (Figure 2-1)
1.The pressure supply must be clean, dry gas, nitrogen or air and at the correct pressure, refer to the specification (Section 6).
2.Ensure the user systems can be isolated and vented.
3.Connect pressure and vacuum supplies to the SUPPLY + and SUPPLY - connection ports.
4.Connect the Unit Under Test (UUT) to the required outlet connection port.

PACE Pressure Controller User Manual
Installation
The instrument requires a positive pressure supply, instruments operating in an absolute range or negative pressure range require a vacuum supply. A vacuum supply should be used for a fast response for instruments operating near atmospheric pressure. For dual channel operation two independent pressure and vacuum supplies can be used.
Important notes
When using two pressure modules, make sure that the modules are compatible, refer to Section 4.9. All connections must comply with the Pressure Equipment Directive (PED).
When connecting the output ports of two pressure modules together make sure both are either:
•below 70 bar. OR
•between 100 to 210 bar.
To comply with the Pressure Equipment Directive (PED) do not mix these categories.
Supply equipment
Pneumatic supplies should have isolation valves and, where necessary, conditioning equipment. The positive pressure supply should be regulated to between 110% of the full-scale pressure range and MWP stated on the control module.
To protect the control module, for ranges above 100 bar, from over-pressure a suitable protection device (such as a relief valve or bursting disc) must be fitted to limit the applied supply pressure to below the MWP.
On instruments without a negative supply, the positive pressure discharges from the system to atmosphere through the negative supply port. Fit the diffuser to the negative port to diffuse airflow.
During system pressure vent operations, the pressure discharges from the system to atmosphere through the vent port. Fit a diffuser to the vent port to diffuse airflow.

2.5 Rack-mount option (Figure 2-5) General
There must be enough space at the rear of the instrument for all the cables and pipes. The length of the cables and pipes must allow for the removal and fitment of the instrument. The cooling air of the instrument must not be obstructed. Allow a free flow of air through the equipment rack and around the instrument, especially at high ambient temperatures.
Example instrument
Figure 2-5 Rack-mounting
Procedure
• Locate and secure the back brackets |
to the rear of the equipment rack. |
• Unscrew and remove the four countersunk screws from each of the instrument side panels.
• Locate the two brackets on each side of the instrument and secure with the four countersunk screws.
• Support the instrument and connect the cables and pipes.
K0443 Issue No. 3 |

2 Installation
•Refer to the electrical connections below before finally fitting the instrument into the equipment rack.
•Temporarily locate and screw in the two spigots* to each side of the equipment rack.
•Locate and slide the instrument into the rack, locating the instrument on the spigots*.
•Secure the instrument in the equipment rack with two of the screws and washers (supplied).
•Remove the two spigots* and replace with the remaining two screws and washers (supplied).
2.6 Electrical connections WARNINGS
1.THE GROUND LEAD OF THE INSTRUMENT MUST BE CONNECTED TO THE AC SUPPLY PROTECTIVE SAFETY GROUND.
2.ISOLATE THE POWER SUPPLY BEFORE MAKING ANY ELECTRICAL CONNECTIONS TO THE REAR PANEL.
General
The instrument must be connected to the correct electrical power supply as stated on a label next to the power connector. Also see section 6 Reference and Specification.
Make sure that the power supply is off before connecting the power cable.
Requirements for rack-mounted instruments
•Install an isolator in the power supply circuit. The power supply connector and switch on the rear panel of the instrument will not be accessible.
•Set the power supply isolator to OFF. Connect the power supply and set the power supply switch to ON before sliding the instrument into the rack.
•Set the power supply isolator to ON .
Check that the front panel display shows the power-up sequence.
Connecting (Figure 2-6)
To connect the power supply to the instrument proceed as follows:
•Insert the IEC power connector (1) into the power supply connector at the rear of the instrument.
•Set the ON/OFF switch to ON.
•Check that the front panel display shows the power-up sequence.

2 Installation
IEEE 488 Interface
This interface complies with IEEE 488 standard. The IEEE 488 parallel interface connects a computer/controller to one or more PACE instrument and possibly other instruments. Up to 30 instruments can be connected through a high-speed data bus to the computer/controller.
Note: The length of each IEEE 488 cable must be less than 3 metres to comply with the EMC requirements, see Section 6 Reference and Specification.
Single Unit Installation (Figure 2-8)
Connect an IEEE 488 connector/cable assembly to the rear panel IEEE 488 connector of the instrument.
•Connect the other end of the connector/cable assembly to the IEEE 488 connector on the controller/computer.
•Change the IEEE 488 communication parameters as described in the Supervisor set-up (refer to Section 6.7).
Multiple Unit Installation (Figure 2-8)
To install multiple units use stacking plugs to link from first instrument to the second instrument. Proceed as follows.
•Connect a pair of IEEE 488 stacking connectors to the rear panel IEEE 488 connector of the instrument
1Connector to rear panel of first instrument.
2Connector from controller/computer.
3Connector to rear panel of second instrument.
•Connect the other end of one of the connectors to the IEEE 488 connector on the controller/ computer and the other connector into the next instrument

•Repeat this procedure for all the instruments in the system.
•Use the Supervisor set-up (communications) menu on each instrument to set-up the required communication parameters (refer to Section 3.8).
