The Barometric sensor in a PACE 1000 is a 2000mbar absolute sensor.
The instrument will work and display correctly at pressures below 750 mbar abs.

The firmware upgrade does not affect the calibration of the instrument.
All the calibration data is stored within the sensor itself. The PACE 1000 just displays the digital signal that is coming from the sensor.

The Switch Test comes with either the Analogue Output option or the VFC option.
One of these options will need to be fitted to the PACE 1000 in order to have the Switch Test feature.
Check if you have a connector on the rear panel in the „Option” position

If you have an option connector then the Switch Test is installed.

The PACE 1000 display reading is updated two times per second, this would be the same for both the IPS and IRS sensors.

The comms update rate is 8 timer per second.

The Update Rate of the TERPS sensor itself is 5 to 400 New data readings per second.

The Update Rate of the IPS sensor itself is 440 to 3520 New data readings per second.

The Gross Leak Detected message is displayed if the leak rate is greater then 5% of the Test Pressure value per minute.

This message indicates that the temperature reading from the sensor is incorrect.
The sensor will still respond to pressure but may have an offset at Zero.
We recommend replacing the Control sensor.

As it is not a high pressure application plus the Control Module pressure sensor will have a Stainless Steel diaphragm and there is only 5% Hydrogen, it will be Ok to use ARCAL 5 with a 7 bar g Control Module.

Our site compressed air that we use with our PACE controller mini rigs is specified as:
Dried to <-26°C pressure dew point (Residual water content 110ppm) Filtered to 99.9% of <1 micron particles.

CM0, 1 & 2 are all gauge sensors, CM3 is absolute.

CM3 will only work in “pseudo-gauge” mode if the CM3 is a CM3-B In pseudo-gauge mode the reading on screen is still coming from the CM3 TERPS sensor (TERPS minus baro = pseudo gauge e.g. 2000mbara – 1000mbara (baro) = 1000mbarg). The reading is not from the CM2 gauge sensor, which is also installed.

The traditional “zero” function on CM0, 1 and 2 cannot be used on CM3 2bar & 3.5 bar as it negatively affects the overall uncertainty of the CM3 sensor.
If you are using the CM3 in pseudo gauge mode and you press “zero” you are not zeroing the gauge sensor, you are taring the CM3 absolute sensor against the baro (e.g. 1001mbara (REF) – 1001mbara (baro) = 0mbarg)

The PACE controllers are designed to control into a sealed system that is leak tight.
We do not have a value of the maximum leak rate that the PACE is able to supply.

Helium is not a suitable media to be used with PACE controllers because over time (unable to predicate the time scale) it may affect the performance and damage the
sensors diaphragm and valves.

A Cycle Count of 9999999 can be entered into the Test Program.

Any of the soft options can be enabled locally.
An order for the option(s) needs to be sent to the Customer Care Team. They will then provide a 10 digit activation code for the option(s) requested.

To enable the option(s) follow the „Option Enable Process” described in section 6.8 of the PACE 5000/6000 user manual K0443.

It is not possible for PACE to control down to 0.1 Torr abs (0.13 mbar abs).
For PACE to control there has to be a differential pressure across the valve, at such low pressures there will be very little differential pressure across the valve.
Our engineering team have previously managed to control down to 2 mbar abs but this was very difficult to achieve, therefore this is not an application that we would
recommend PACE for.

The Leak Rate specification for all Control Modules is 0.05% FS per minute.

The leak rate specification is 0.05%FS/min using a Control Dwell of 3 minutes and Measure Dwell of 1 minute. The leak rate is measured over the Measure Dwell time.
Therefore for a 10 bar control module (CMO-11G) this would be 0.005 bar/min.

The PACE 5000 has a maximum power rating of 100VA.

Insert the following two lines before the ID_PROG_END line:

ID_PROG_BREAK
ID_PROG_VENT
ID_PROG_END

When you press the Stop icon the program should go to the BREAK line in the program and then perform a VENT.

Only one port at a time can control the PACE, for example from PC/PLC A, though other ports can read/listen at the same time, for example from PC/PLC B .

For the pressure media the PACE datasheet states: „Dry, oil free, non-corrosive gas maintained at a value of 10% above the maximum required outlet pressure, Dry air or Nitrogen recommended.”

We would consider Dry Air as Air that has a Dew Point of -40°C or below.

Bottled Nitrogen or bottled Dry Air from a reputable supplier would be suitable.

The Power Consumption will be no more than 250W as this is what the PACE 6000 Power Supply is rated to.

1. With the instrument set to dual display mode, a separate Test Program can be run on each control module simultaneously.

Each control module will be running
independently.

2. You only need to purchase one Test Program option. Test Programs can then be written and assigned to each module.

General rules in Test Program:
When running a Test Program, the RANGE command can only be used to select a sensor on THIS module – if it tries to select a sensor on the OTHER module it will crash we cannot defend this in code.

Therefore the Test Program cannot be used in single screen auto-ranging mode.

With the instrument set to single screen mode and independent ranges a Test Program can be run on the range that has been selected.

Basically, whichever module you want to set up in the analogue output settings needs to have been selected in the range first.
You should be able to use:
• Analogue output 1 and 2 to monitor Module 1 OR
• Analogue output 1 and 2 to monitor Module 2 OR
• Analogue output 1 to monitor Module 1, analog output 2 to monitor Module 2 OR
• Analogue output 2 to monitor Module 1, analogue output 1 to monitor Module 2

Fitting the Control Modules the opposite way round in a PACE 6000 won’t cause any safety issues – providing all other safety concerns are correctly addressed.

The software doesn’t 'know’ which module is fitted in what position but it assumes that the rules stated in the manual are obeyed.

So if the modules are fitted the wrong-way-round they will still be displayed according to the software rules.
That is when in dual screen mode the lower s/n will appear on the right side of the display even though the control module is actually fitted on the left side of the instrument (when looking from the front). This may cause some confusion.
There could possibly be some operational issues if the instruments are being controlled remotely.

The max airspeed for the PACE is 650 knots.
Therefore for Airspeed you can use a CM3-B 2 bar abs, this will give 1 bar pseudo gauge which would cover the range of 650 knots (866 mbar).
For Altitude you can use a CM3 2 bar abs.

What is the PACE Aeronautical option

The Aeronautical Option is installed on the PACE 6000 chassis.
The Aeronautical can be added at a later date. You would need to place an order for the option, we would then supply a 10 digit code that can be entered into the PACE 6000
to enable the option.
