The Protec P3000 helium leak detector is supplied ready for operation. However, we recommend that you carefully read the Technical Handbook to ensure optimum operating conditions right from the start. This handbook contains important information on functions, installation, start-up and operation of the Protec P3000.
If not stated otherwise this technical handbook applies to all three configurations of the Protec P3000 (see Section 1.1.2). Sections specific to one configuration are marked as "for … only". Sections marked as "for Protec P300 0XL only" always apply to the Protec P3000XL with the SL3000XL sniffer line (capable of
1.1 Introduction
1.1.1 Intended Use
The Protec P3000 is a helium leak detector for sniffer applications. It may be used to localise and quantify leaks in test samples if there is helium under an overpressure within the test sample and when searching the test sample with a sniffer probe from the outside (sniffer method). The use of this sniffer probe is mandatory for proper operation and it is available as an accessory (Cat. No. 525-001 to 525-004).

The Protec P3000 must not be operated while standing in water or when exp osed to drip water. The same applies to all other kinds of liquids.
This Protec P3000 should only be used in rooms.
Avoid contact of the Protec P3000 with bases, acids and solvents as well as exposure to extreme climatic conditions.
Ensure sufficient air cooling (see also Section 1.1.2)
General Information 1-1
1.1.2 Available Configurations
The Protec P3000 leak detector is available in four different configurations:
The Standard Pr otec P3000
The standard Protec P3000 should be used for high sensitivity applications. It requires the SL3000 sniffer line.
The Protec P3000, RC version
The Protec P3000, RC version is the standard Protec P3000 but with an external display unit. It requires the SL3000 sniffer line.
The Protec P3000XL
The Protec P3000XL is the leaks at a much higher distance from the potential leak at reduced sensitivity but can be switched back to normal flow at inc reased sensitivity. In order to use both flow modes (high and low) it requires the use of the SL 3000XL sniffer line. It may also be operated with the normal SL3000 sniffer line, in this case the high flow mode is disabled, however.
The Protec P3000XL, RC version
The Protec P3000XL, RC version is identical to the Protec P3000XL, but with an external display unit. It requires the SL3000XL sniffer line.

Autozero
Determination and compensation of the helium background. With this function, the internal ZERO level of the leak rate signal is determined in order to avoid a readout of the internal helium background and mistaking it as a properly measured value. If subsequently negative leak rates are obtained due to this correction , the stored offset values are changed so that ZERO will be the lowest value which can be obtained. In this way the values adapt automatically to a decaying background (adaptive background correction).
Internal background
The existing partial pressure in the measurement system. The level of the internal background is measured all the time and subtracted from the measured signal.

2 How the Protec P3000 Works
2.1 Description of the Functions
The Protec P3000 takes in helium through the SL3000 sniffer line, detects the amount of helium by means of a helium sensitive sensor and converts the sensor signal into quantitative leak rates.
The Protec P3000 is composed of the following principal subassemblies:
• A Wise Technology sensor as helium detector
• A valve holder for controlling different operating stati
• A diaphragm pump for pumping the gas to the sensor
• An inlet system for the gas flow
• The correspond ing electrical and electronic subassemblies for supplying power and for signal conditioning.
The detector operates under gross vacuum conditions, i. e. the operating pressure at the detector is several 100 mbar. T he under pressure is generated by a diaphragm pump. The pressure in front of the sensor is measured with a piezo-resistant pressure gauge and is about 250 mbar under normal operating conditions.
2.2 Description of the Subassemblies
2.2.1 Backing Pump
A diaphragm pump in the Protec P3000 serves as the backing pump. All data and further information on this pump are given in the Operating Instructions. The backing pump generates the flow of the gas through the SL3000 sniffer line.
2.2.2 Wise TechnologyTM Sensor
The helium detector (Wise TechnologyTM sensor) consists of a closed glass container with a measurement device for the precise determination of the pressure inside the glass housing and a mem brane chip wit h a large nu mber of small quartz windows. The membrane is permeable only for helium, all other components of air are retained by the membrane and from the inside of the glass housing. The Quartz membrane is heated so that the permeation for helium is sufficiently high and fast.
Inside of the glass housing the total pressure is measured precisely. As only helium can enter the glass housing the total pressure is equal to the partial pressure of helium. The determined total pressure inside the housing is proportional to the helium partial pressure outside the sensor.
2-1 How the Protec P3000 Works
2.2.3 Valve Holder
The valve holder carries the valves that control the gas flow to the Wise Technology sensor. These valves are used to select the sensitivity of the system, to activate a protection mode against high helium contamination and to set the system into
STANDBY mode. The Protec P3000 software continuously analyses the situtation and
sets the correct valve position via the control unit.
2.2.4 Control Assembly
The control assembly (microprocessor) is the central assembly of the Protec P3000’s electronics. All other subassemblies are controlled and monitored by this assembly. The microprocessor which is located here is thus continuously informed about the status of the entire Protec P3000 and can respond accordingly. In order to accept commands from the operator and to output measured values and messages, the control subassembly is linked to the display unit.
2.3 Description of the Displays and User Interfaces
2.3.1 Main unit display
This subassembly is used to communicate with the operator. It accepts commands from the 8 keys on both sides of the display and outputs measurement results and messages via the display.

The probe handle also offers some LEDs in the flange of the sniffer tip in order to illuminate the location currently being leak tested.
How the Protec P3000 Works 2-4
Warning
Do not stare into the LEDs of the sniffer line intentionally for extended times or at a close distance as this may cause permanen t da ma g e to th e ey e.
The LEDs offer some bundled light. The intentional starring suspends the lid closing reflex and also the eyes do not move anymore which may le ad to overhea ting of the retina.
When looking into the LEDs „incidentally“ the eye is protected by the lid closing reflex. Also the permanent movement of the eyes prevents overheating and consequent damage of the retina.
2.3.3 Built-in PRO-Check reference leak
A built-in PRO-Check reference leak is available for all Protec P3000. The PRO­Check reference leak can be used for verifying the correct functioning of the Protec P3000 including the correct calibration and can also be used for re-calibrating the Protec P3000 if necessary.
The PRO-Check reference leak is inserted in the front of the h ousing. Insertion of the sniffer tip into the cone-shaped test leak opening is automatically detected via a light barrier.

3.4.1 Standard Operation Mode
Provided the Protec P3000 has been set-up to meet the requirements of the particular application and it has been calibrated (see Section 3.5), a measurement is performed as follows:
3-6 Operation of the Protec P3000
First briefly operate the ZERO button on the sniffer probe. This will ensure that the Protec P3000 eliminates all interfering influences which may affect the ZERO level (i.e. the detection limit of 1x10
-7
mbar l/s). Next hold the tip of the sniffer as close as possible to the suspected leak, if required the tip may even touch the te st object. If a welded seam or alike needs to be tested, the tip should be moved at a velocity of no more than 13 cm/s (5 inch per second) along the welded seam. The distance between tip and test sample should be as small as possible.
If a leak is detected the bar will grow. The Protec P3000 continuously compares the measured leak rates with the programmed trigger levels. If the trigger is exceeded the background colour of the probe display will change from green to red. At the same time an alarm sound will be released by the speaker in the probe handle and the probe handle will start to slightly vibrate. As an additional indication of exceeding the trigger value the three white LEDs in the flange of the sniffer tip will start flashing.
Fig. 3-6 Sniffer display when detecting a leak
As soon as an acoustic alarm sounds, the tip should be removed from the spot being tested. After displaying a constant leak rate the ZERO button should be pressed again to repeat the test. Thus, a measurement error can be prevented and the lea k can be located.
For Protec P3000XL only:
The Protec P3000XL allows the use of the HIGH FLOW mode (requires use of SL3000XL sniffer line). When set to HIGH FLOW mode leaks may be detected at a larger distance from the potential leak. The high flow mode is indicated by the gas type being displayed in inverted colors (o n the pr obe display as well as on the m ain display). When testing for joints, the sniffer tip should be no further than 10 mm (0.4 in) away from the joint. If testing a weld ed seam (or alike), the sniffer tip should not be moved faster than 4 cm/s (1.6 in/s) at a maximum distance of 10 mm (0.4 in) from
the welded seam.
Operation of the Protec P3000 3-7
If a leak is detected (and accessibility allows so) switch the Protec P3000XL to LOW FLOW mode (by pressing the right probe button) for easier localization of the leak. The gas type will now be displayed not-inverted. Now search for the leak again by bringing the sniffer tip as close as po ssible to the potentially leaking area. Localize the leak by moving the sniffer tip back and forth across the suspected ar ea. The leak will occur where the leak rate signal shows the maximum leak rate.

3.4.2 I•Guide Operating Mode
The I•Guide operating mode has been introduced to suppor t the operator in applyin g proper sniffer leak detection technique.
The I•Guide operator guiding mode allows to store pre-programmed parameters for different units under test. The number of locations that need to be tested per specimen, the time each location needs to be tested for as well as the time required to move to the next location may be programmed. In add ition, a ma ximum allowab le global leak rate for the total unit under test is stor ed. In the I•Guide mode up to 10 pre-programmed testing procedures can be stored.
Notice If the number of locations to be tested is set to zero, the Protec P3000 will
operate in a continious mode without checking for a global leak rate but still issue the timer signal for proper testing.
3.4.2.1 Starting the I•Guide Mode
To start the I•Guide Mode go to the main menu and choose SET UP I•GUIDE. In the opening menu go to the top line item and change the setting to side push button and press enabled I•Guide program in the list. A message screen will pop-up notifying the operator that I•Guide has been activated (the gas selected in the I·Guide program you choose).
For how to set-up and I•Guide program please refer to Section 4.4.4. To switch back to the Standard Operation Mode select “

3.5 Calibration and Self-Test
The Protec P3000 can be calibrated internally with the built-in PRO-Check re ference leak or externally with an external calibrated leak (Cat. No. 122 37 - 122 39).
Notice If a calibration is started during the first 20 minutes after power on, a
warning will be issued. Do not calibrate the Protec P3000 during the first 20 minutes after start-up.
Also a verification of the calibration may lead to wrong results in the first 20 minutes after start-up.
Only confirm and continue with the calibration if the real warm-up has been longer than 20 min. (e.g. after a quick restart of the Protec P3000.)
The built-in PRO-Check reference leak can be used for a self-test of the Protec P3000 as well as for internal calibration.
Notice The PRO-Check reference leak is a temperature compensated leak. It
must only be used when electrically connected to the main unit, either when inserted into its port or when connected to the main unit via a Sub-D extension cord. The leak rate printed onto the body of the PRO-Check is only valid at 20°C (68F) and will vary greatly with temperature and time.
To compensate for this the PRO-Check reference leak is equippend with a temperature sensor and a compensation curve is stored in the software which automatically compensates the test leak rate for changes in temperature when connected to the main unit.
A calibration or verification with the PRO-Check reference leak not being connected to the main unit will cause a wrong calibration of the Protec P3000 and / or will lead to wrong testing results.
3.5.1 Verifying a calibration (proof function)
Notice A verification can only be performed while the unit is in one of the two
measurement modes: standard operation mode or I•Guide operation mode. A verification will not be started if the main menu is opened.
If the sniffer tip is inserted into the opening of the PRO-Check reference leak a verification of the calibration (proof function) will be started automatically. While holding the sniffer tip in the test leak opening, the unit will check the re ading from the PRO-Check. Afterwards the operator will be requested to remove the sniffer tip from the leak opening.
Notice Any time during the verification procedure an internal calibration may be
started by pressing either the right sniffer probe button or the CAL button on the main display.
The results of the verification will be displayed in a summarizing screen. If the verification process was successful, the message "sensitivity check OK" will be displayed.
Operation of the Protec P3000 3-15
Fig. 3-16 Results of proof function for Protec P3000 If the value measured for the PRO-Check is out of range, the message "recalibration
required!" will be displayed in inverted colors. For returning to the measuring mode, please press the right probe button or press
“
OK” on the main display.
For Protec P3000XL only
For the Protec P3000XL both calibration factors for
HIGH FLOW and LOW FLOW mode
will be verified (see fig. 3-16). However, only the information for the selected flow mode will be relevant for passing or failing the verification. The results for the non­selected mode will be displayed for reference at the bottom of the results screen.

3.5.2 Internal calibration
Notice A calibration can only be performed while the unit is in one of the two
measurement modes: standard operation mode or I•Guide operation mode. A calibration will not be started if the main menu is opened.
If the sniffer tip is inserted into the opening of the PRO-Check reference leak with the right probe button pressed while in measurement mode a calibration will be started automatically. While holding the sniffer tip in the test leak opening , the Protec P3000 will measure the test leak. Afterwards the operator will be requested to remove the sniffer tip from the leak opening.
After completion of the internal calibration a screen summarizing the results of the calibration will be displayed. The old calibration factor as well as the new calibration factor will be displayed. If warnings are active and have been acknowledged during the calibration process, the message is endorsed with the information "with active warnings".
Fig. 3-18 Results of internal calibration To avoid unintended overwriting of a previous external (more accurate) calibration,
the operator needs to “Accept new values (anyway)?”.
3.5.3 External calibration
For external calibration it is recommended to use leak rates > 5x10-6 mbar l/s for Protec P3000 and leak rates of > 5x10 P3000XL at
HIGH FLOW (3000 sccm).
If the reference leak rate is < 5x10 calibrates in
LOW FLOW mode.
Notice If significantly increased backgrounds are prevalent in your production
environment, larger leak rates for the calibration leak may be required.
The external calibration is a semi-automatic process during which the user will have to follow some instructions. The calibration process may be starte d via the “ button from the measuring mode at any time (except when the menu is open or the function has been locked). A running calibration process may be cancelled by operating the “
ESC” button.

and enter the correct leak rate value. Press “START” afterwards to begin with the calibration process.
Fig. 3-19 Setting-up the leak rate of the external leak Please hold the sniffer tip to the outlet of the external calibrated leak. Hold the sniffer
tip steady and very close to the opening, however, do not clog the opening with the sniffer tip. Some air also needs to enter the sniffer tip in addition to the helium from the external calibrated leak. If the leak rate signal indicated by the bar graph is stable press “
OK”. Keep holding the sniffer tip steady in front of the opening while the Protec
P3000 reads the leak rate of the calibrated leak. During this time the text “Please wait…” will be displayed.
Fig. 3-20 Calibration screen during external calibration When the analysis of the calibrated leak signal is completed a message “sniff air!”
will be displayed. Remove the sniffer tip from the opening of the calibrated leak and hold the sniffer tip into the air, as far as possible from any sources of helium. Wait until the bar graph shows a stable signal again and press “ok” once more.

3.6 Standby
If not used, the Protec P3000 will go into a STANDBY mode automatically after a predetermined time in order to avoid wear of parts during times not used. In this
STANDBY mode the flow through the sniffer line will be shut down to conserve filters
in the sniffer line as well as to save sensor life time. If the operator picks up the sniffer line, a movement sensor will detect this action and
will set the Protec P3000 back into normal operation. The Protec P3000 will be ready for measurement again after approx. 5 seconds.
For details on how to set the time until the Protec P3000 goes into please refer to section 4.3.1 (
VACUUM & ACCESS, STANDBY DELAY)
3.7 Shutdown
To shut down the Protec P3000, set the ON / OFF main switch (Fig. 3-1/6) to the „0“ position regardless of the operating mode of the Protec P3000. Nothing else is required. The parameters entered are saved by Protec P3000. After switching on, the Protec P3000 will revert to the same status it was in when it was switched off before.
3.8 Storage for fast availability as back-up unit
STANDBY mode
Due to accumulation of Helium (from air) in the sensor unit during storage the start­up time for the Protec P3000 will be approx. 1.5 min per day of storage with a maximum start-up time of approx. 1 hour.
If you want to use the Protec P3000 as a back-up unit to ensure uninterrupted availability of your production line, the Protec P3000 should be stored as follows.
1 Shut down the Protec P3000 but keep it connected to a power outlet. 2 Put a clock timer between the Protec P3000 and the power outlet. 3 Program the clock timer to switch on the Protec P3000 for 1 hour twice per week (at
least every 4 days).
Notice The clock timer should be battery buffered so that in case of a loss of power
in the factory, the clock timer does not loose its pre-programmed window for power on.
With this approach the max. start-up time will be approx. 7 min.

4.3 Selecting gas equivalents and setting trigger values
The Protec P3000 can detect leak rates as helium leak rates or in refrigerant equivalent leak rates. Up to four different sets of parameters can be stored by the Protec P3000. Only one type of leak rate, however, will be displayed in the measurement screen optional with the equiva lent Helium leak rate in addition. In the gas / trigger menu the chosen gas equivalen ts are displayed with their curr ent trigger value.
With default settings only helium is set up in the first set of parameters. The remaining three sets are blank ("<------>"). Only sets that have been edited will be listed in the list of gas parameters that can be loaded directly from the measuring screen through the list button.

For all normal operation the I•Filter should be selected. I•Filter is an intelligent filtering algorithm that yields the best results with respect to noise level and stability of leak rate values specifically developed for use in the Protec P3000 leak detector.
Only in cases where the older Protec model is replaced by an Protec P3000 and the leak detector is used in a fixed testing system it may be required to stick with the “
FIXED” filter that was used in the Protec.
Default: I•Filter
Under conditions with very unstable background conditions it may be favourable to not issue an alarm immediately but only release an audio alarm if the trigger leve l has been exceeded for an extended time. This alarm delay can be entered in 1/10 of a second. Values between 0 and 9.9 sec will be accepted. Default value: 0.0 sec (i.e. disabled).

Default setting: local and RS232
Notice Even with the control location set to RS232 some parameter may still be
4.5.2 Recorder outputs
The RECORDER OUTPUT SCALE is linear and logarithmic. The linear output signal is provided through channel 1 (pin 1 of the I/O port) and the logarithmic output is provided through channel 2 (Pin 14 of the I/O port) (see Section 6.1).
In logarithmic output scale the voltage range is 0 - 10 V. Beginning at 1V, each leak rate decade is spread over 2 volts, i.e.:
1…3V: 1 3…5V: 2 5…7V: 3 7…9V: 4
Thus a leak rate range of 4 decades will be output by way of an analog signal. The four decades are set through the value and the unit of measurement for the trigger level. The software of the Protec P3000 will set the output voltage in such a manner that the trigger level itself will always be set within the second decade (i.e. within the range of 3 to 5 Volts).
LOCAL AND RS232 mode the Protec P3000 can be controlled via the
able to be changed through the main units software menues. Please lock these by activating the menu PIN to prevent unitended changes.

Converting a trigger leak rate to a trigger output voltage
If you want to know the corresponding voltage for a specific trigger leak rate, the following formula applies:
U = 3 + 2·log (mantissa of scientific notation of trigger value) (The factor of 2 is used since one decade is spread over 2 Volts. The summand of 3
is used because the trigger level will always be within the range of 3 to 5 V).

The Protec P3000 is equipped with three electrical control connectors. The electr ical connections (head phone, I/O port and RS232) are located on the rear of the main unit directly next to the socket for the mains cable.
6.1 I/O Port (Control Inputs and Outputs)
For all contacts of the I/O Port a maximum voltage of 60 V DC or 25 V AC must not be exeeded or reached to ground or ground equipment conductors. According to the type of in- or outputs lower voltages had to be accepted. For this, please refer to the information given in the responding chapters.
Through this connection some functions of the Protec P3000 can be controlled externally or measurement data or the of the Protec P3000 status may be communicated to external equipment.
Through relay change over contacts the trigger levels as well as th e operating mod e (Ready) of the Protec P3000 may be monitored.
