Installation

The safety of any system incorporating the equipment is the responsibility of the assembler of the system.

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.

Figure 2-2, Pressure module rear view

Note: When using two pressure modules (Ref: Section 4.9, Pressure module replacement) make sure that:

•The module with the highest pressure rating is fitted to the right hand side Module 1 position as viewed from the rear of the product refer to (Ref: Fig 2-2)

•If two modules have the same pressure rating, make sure that the module with the higher serial number is fitted to the right hand side Module 1 position as viewed from the rear of the product.

Note: All pneumatic connections must comply with the Pressure Equipment Directive (PED) or other regional pressure standards.

Note: 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 prevent over-pressurisation of pneumatic parts and maintain compliance with the PED do not mix categories.

K0443 Revision A

PACE Pressure Controller User Manual

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 instrument from over-pressure a suitable protection device (such as a relief valve or bursting disc) must be fitted to prevent over pressurization.

On instruments without a negative supply, the positive pressure discharges from the system to atmosphere through the negative supply port. Pipe the negative port to a safe discharge area or fit a diffuser to the negative port.

During system pressure vent operations, the pressure discharges from the system to atmosphere through the negative and vent ports. Pipe both ports to a safe discharge area or fit a diffuser to the negative port.

Pneumatic Connection Examples (Ref: Figures 2-3, 2-4 and 2-5)

†Optimum controller transient response and minimum time to set-point may be degraded if either the pneumatic supply or vacuum system has restricted flow. Installing a reservoir volume, which has larger capacity than the load volume, located in close proximity to the controller supply ports can improve the controller response.

‡Optional negative gauge pressure generator kit.

To protect the control module, for ranges of 70 bar and above 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.

AUTO-RANGE (only available with two-channel instruments)

Note: Not all Auto-Range and task functions are available using the remote communications, this allows more flexibility to the remote programmer.

Controller Off – Increasing Set-point

With both controllers in Measure mode, if a set-point within the range of the lower ranged controller is entered and Control is then selected the lower ranged controller controls to the entered set-point.

With both controllers in Measure mode, if a set-point above the range of the lower ranged controller is entered and Control is then selected, then the range is changed to the higher ranged controller and this then controls to the entered set-point.

Controller Off – Decreasing Set-point

With both controllers in Measure mode, if a set-point within the range of the higher ranged controller is entered and Control is then selected the higher ranged controller controls to the entered set-point.

With both controllers in Measure mode, if a set-point above the range of the lower ranged controller is entered and Control is then selected, then the higher ranged controller will control to this set-point. When the controller is in limits then the range is changed to the lower ranged controller and this then controls to the entered set-point.

Controller On – Increasing Set-point

With the lower ranged controller in Control mode, if a set-point within the range of the lower ranged controller is entered then the lower ranged controller controls to the entered set-point.

If the set-point is increased to above the lower range but still within the higher range then the lower range controller switches off and that the higher range controller switches on and controls to the entered set-point.

Controller On – Decreasing Set-point

With the higher ranged controller in Control mode, if a set-point within the range of the higher ranged controller is entered then the higher ranged controller controls to the entered set-point.

If the set-point is decreased to within the lower range then the higher range controller will control to this set-point. When the controller is in limits then the range is changed to the lower ranged controller and this then controls to the entered set-point.
