Theory of operation

The system to be tested is filled with a mixture of
helium/air.

The probe is passed over areas considered to be
critical and, via a sampling pump, the mix of gases
around the areas examined is sampled and piped
towards the internal sensor.

The sensor consists of a pressure detector and of a
heated quartz capillary which is highly permeable to the
molecules of helium, while permeability for all other
atmospheric gases is negligible.

Theory of operation

While the atmospheric gases are vented to the outside,
the molecules of helium reach the pressure detector.
The electric signal proportional to the partial pressure
of the helium taken from the detector, is processed by
the microprocessor of the central unit. This permits
direct readout of the concentration of helium on the
display (ref. figure below).

TECHNICAL INFORMATION

15 87-900-120-01 (A)

Basic unit

The PHD-4 is controlled by a single microprocessor
type board and includes:

• front graphic display and keypad;

• PCB with the circuits for control of sensor and the

pressure measurement circuit;

• helium sensor for partial pressure measurement
with integrated HV board for powering of the
sensor.

• Pneumatic line consisting of the membrane pump
for sampling of the environmental gases, of the
twin-stage filter system and the backflow valve for
protection of the sensor.

• probe, connected to the basic unit with the spiral
tube that can be extended to a length of 1.5
meters.

Sensor protection

The sensor is protected against excess flow of helium
by the so-called "protection set-point" (inside the set-

point icon

, identified by the number "5").

This function can be used to determine the safety
threshold above which the sensor is protected (see
table below) activating the most suitable type of
protection according to the test in progress.

TECHNICAL INFORMATION

Protection level 1 (enabled in factory):

The backflow valve fitted in series with the sampling
line is activated preventing further pumping of the
gases rich in helium and, at the same time, "purging"
the entire sampling line with helium-free atmospheric
gases (sucked in from the exhaust point or in a helium­free environment using a dedicated line - see note).

Functioning of the backflow valve is showed in the
figure below.

Restricting delivery of helium to the sensor, this
protection extends its lifetime, also guaranteeing
maximum sensitivity.

As it restricts the amount of helium conveyed to the
sensor, tripping of the backflow device shortens waiting
times between one measurement and the next (zeroing
time).

Protection level 2:

Temporary switching off the heating element of the
sensor drastically reduces the permeability of the
sensor to helium, increasing the total level of
protection.

NOTES:

The line dedicated to suction of the cleaning gas must
have a maximum length of 5m and consists of
4x0.75mm tube.

The position of the backflow valve A is shown in the
figure below.

3. Using a tool, unscrew the sintered filter C located
inside the cone.

4. Clean the filter with a grease remover and dry with
dry compressed air. Check the connections and
inspect the flexible tube for any damage.

5. Retighten the sintered filter and the sampling cone

Sampling pump

The sampling pump is the device that makes it possible
to move the gas to be analyzed from the point where a
leak is suspected to the sensor inside the PHD-4.
This function is afforded by the micromembrane pump
which, as it sample the gas required for analysis (leak
check), also allows any impurities in the gas (dust,
water, oils, etc.) to pass through.

These impurities tend to accumulate inside the
pumping element with a consequent gradual reduction
in performance until a fault is generated.

This phenomenon is effectively contrasted by the two
filter elements (see glass wool filter and sintered filter)
and by the sampling auto-adjust cycle (see the chapter
on “Sampling auto-adjust”); however, it is important to
restrict flow of these materials inside the sampling
pump.

If sampling pump performance is inefficient (this
condition is notified during the initial automatic test)
after use in a particularly “dirty” environment or after
many hours of operation, the pumping block must be
replaced.

To replace the pumping block, proceed as follows:

1. Remove the housing as described above.

2. Place the inside block of the PHD-4 on a flat
surface able to support its weight, positioning the
device so that the lower part (sampling/filter zone)
is accessible

3. Disconnect both air tubes A (inlet and exhaust of
the sampling pump).

4. To remove the delivery tube, press down ring B so
as to free the tube to be removed.

5. Disconnect the two-pin pump power supply
connector C.

element

8. Insert the new pump in retention spring D and then
connect the power and air supply using the two
non-reversible inlet and exhaust tubes.

USER INTERFACE

The PHD-4 helium leak detector is designed to operate
in different environments and in different applications.
The many different functions necessary to operate
efficiently in a wide range of different conditions are
managed directly by the microprocessor on the CPU
control board. The microprocessor guarantees
complete control of the capabilities and of the internal
components via the HID (Human Interface Device).

To start the HID and therefore to switch on the PHD-4,
press and hold down for at least 3 seconds the first key
A to the right identified by the I symbol.

The HID starts and, after a short wait, the automatic
check on the internal blocks is started (Self test):

Self test

This automatic procedure is initiated by the HID each
time the PHD-4 is started; this process is intended to
guarantee that the measurement made with the PHD-4
is effectively valid, checking correct functioning of the
components and of internal functions.
The self-test cycle comprises the following phases:

• Test on the heater

• Test on functioning of the HV power supply unit

• Battery Pack test

• Ion sensor starting test

• Test on functioning of the ion sensor

• Test on sampling effectiveness

The “Heater Test” function checks continuity of the
platinum resistor for heating of the permeable area
inside the sensor.
Positive outcome of this test guarantees that the helium
sampled, together with the environmental gases, is
able to penetrate inside the sensitive element and can
therefore be detected.
Efficient functioning of the sensor is verified by a further
three tests, the first of which is the “HV test”. During
this test, a check is made to guarantee that a correct
voltage value is present at the output of the HV power
supply unit integrated in the helium sensor.
The “Sensitivity test” is useful for checking that the
helium detection sensor is able to start and is therefore
operative.
The last test carried out on the sensor is the “Sensor
test” consisting in checking of the effective
performance of the sensor.

TECHNICAL INFORMATION

22 87-900-120-01 (A)

The self-test cycle also includes a “Battery test” which
checks that there is a sufficient residual charge for
operation of the PHD-4 and the “Sampling test” which
is useful for checking correct operation of all the
components involved in gas sampling (membrane
pump, sintered filter, glass wool filter, sampling line).

During running of the various tests, the items forming
the list of tests are ticked with a “v” if the test is passed
or combined with the “

!

” symbol in the case of
difficulties in running the tests If, in particular
conditions, some of the tests have to be repeated, the
HID highlights this conditions with the “R” (to be
Repeated) symbol combined with an indication of the
test concerned.

The “PS” (Power Supply) symbol is highlighted on the
“Battery test” line if the battery is not present or if the
fuse inside the battery has blown.

At the end of the test, a summary screen page is
shown; if all the tests have been passed, the message
“Self-test performed successfully” is displayed; if some
of the tests have failed, a list of the problems
encountered is displayed for 20 seconds before
automatic shut-down of the PHD-4.

Complete Measurement screen page

The “Measurement screen page” is the operator
interface provided by the HID. At PHD-4 power-on, the
complete measurement screen page is displayed (see
Complete Measurement screen page) with which it is
possible to display the all-round status of the PHD-4.
If the operator does not press any key for more than 5
seconds, the HID automatically changes data display
mode activating the Large size screen page (see Large
size screen).
The measurement screen page makes it possible to
monitor the main operating parameters of the PHD-4,
the status of the digital interface and obviously the leak
rate measured, in real time.

The leak rate is displayed in the form of a bar whose
length is proportional to the leak rate and also by a
numeric indication in exponential format followed by the
related unit of measurement.

A set of variously positioned icons highlights activation

reception channel of the commands from the outside
(analog input / command from serial).

NOTE

Readout of PHD-4 data is always possible on both
channels (RS232 or Analog port) regardless of
selection of “Remote control”.

Baud rate

Using the “Baud rate” command, it is possible to modify
the communication speed on the serial port between
the PHD-4 and external devices. Possible settings are:
1200-2400-4800-9600-19200.

Set-point

The set-point menu makes it possible to manage
enabling of the five set-points of the PHD-4.

NOTES

When enabled, set points 1 – 4 manage the four relays
on the PHD-4 which can be accessed via the rear
connector “I/O-SERIAL”.

Set-points 1,2,3,4

The set-point selected can be enabled accessing the
items of the individual set-points:

 Enable

It is also possible to modify the enable value of each
set-point completely independently.

NOTES

The factory-set values are:
Set-point 1 : 10PPM
Set-point 2 : 20PPM
Set-point 3 : 30PPM
Set-point 4 : 50PPM

Safety set-point

The fifth set-point made available by the HID is a set­point dedicated to protect the PHD-4 against excessive
exposure to high concentrations of helium.

Accessing the “Safety Set-point” item, it is possible (as
for set-points 1-4) to enable operation and to modify the
tripping threshold in the range 2PPM-250PPM in HS
and 100PPM-600PPM in LS (factory settings 100PPM
in HS and 400PPM in LS).

The Safety set-point menu also contains the item:

Safety actions

 Backflow valve (factory setting: active)
 Heater OFF

This menu makes it possible to manage sensor
protection actions. Protecting the sensor means
restricting the flow of tracer gas (helium) to the amount
strictly necessary to trace leaks.

Backflow valve –

Activation of the backflow valve is part
of the factory settings. This device is tripped when the
threshold set is exceeded and inverts the flow sampled
sampling the gas from the outlet port and then
discharging this through the probe normally used for
sampling.
Backflow functioning makes it possible to use the
helium-free gas present at the outlet port to clean the
entire pumping line and the helium exchange surface
inside the sensor. The device is useful in restricting the
flow of helium to the sensor. In addition to maintaining
correct operation of the sensor, this device also
restricts waiting times between one measurement and
the next (zeroing time).

Heater OFF

– Heater Switching off is a further
protection in addition to the Backflow valve as it
temporarily reduces the permeability of the helium
exchange surface inside the sensor, restricting the flow
of helium to the sensitive element and therefore
guaranteeing correct operation in time.

MAINTENANCE

 Sensor Clean-up

 Reading adjustment
 Sampling auto adjust

PHD-4 Info

The Maintenance menu contains all the management
and self.-maintenance functions of the PHD-4.

 Sensor Clean-up

.

The “Clean-up” function makes it possible to eliminate
any residues of Helium inside the sensor and to obtain
fast, safe reset of the PHD-4.
Use the “Clean-up” function for faster zeroing after
measurement of a large quantity of Helium.

!

Do not start the “Clean-up” function in environments
with large quantities of helium.

 Reading adjustment

The “Reading adjustment” function makes it possible to
eliminate any imprecision in reading.
Start the procedure after correctly zeroing the device in
a helium-free environment.
When requested, provide the PHD-with a known mix of
Helium/Nitrogen (possibly calibrated and certified) and
correct readout using the “∨” and “∧” keys of the
specific screen page.
Follow the operating instructions provided by the HID
throughout the procedure.
In the absence of a calibrated mix, it is possible to use
the P/N Varian 969-3540 sample leak taking into
account that, in this case, reading precision is
approximate.

 Sampling auto adjust

The Sampling autoadjust function offsets the
progressive loss of performance of the sampling line.
Execution of the function is requested by the user
interface every 20 h of operation but can also be
started “manually” at any time ( “Sampling auto adjust”
command).
It is also possible not to start the procedure when
requested (SKIP key) by the HID but this procedure is
initiated subsequently at each start-up until it is
executed.

NOTES

The “Sampling auto adjust” procedure makes an
indirect measurement of the flow sampled; therefore,
in some cases, it may take several minutes.

Battery Pack

The “Battery” menu is the menu used to access battery
pack management functions.

DANGER!

TECHNICAL INFORMATION

27 87-900-120-01 (A)

Battery Maintenance

The “Battery Maintenance” function makes it possible
to eliminate any reductions in autonomy of the Nickel­Metal-Hydrate battery due to the phenomenon
generally known as “Memory effect”.
Cancellation of the memory effect is obtained with fast
complete discharge of the battery.

NOTES

Always start the “battery Maintenance” function after
connecting the connector to the PHD-4.

The “Battery Maintenance” function causes maximum
absorption of current through switching on of the heater
at maximum temperature and of the sampling pump at
maximum speed.
During the discharge phase, the flow inversion valve is
active.

NOTES

If the PHD-4 is exposed to high concentrations of
Helium during discharge, the “battery Maintenance”
function is interrupted in order to protect the sensor
element from saturation.

Charge level

With the “Charge level” function, it is possible to know
the precise percentage residual charge of the battery.
With the power supply connected, no data is shown
(---%).

PHD-4 Info

The “PHD-4 Info” menu provides specific information
regarding the PHD-4 being used.
In particular, it is possible to know:
Part Number, Serial Number, Firmware release,
Working time.

Security

The “Locking” menu makes it possible to protect the
basic parameters of the PHD-4 against modifications.

In particular, the following settings are protected:
Sensitivity, Unit of measure, %Helium, Setpoint menu,
Reading adjustment.

Protection can be enabled/disabled entering the
password (default “00000”).
The password can be modified by the user with the
“Change user password” function.

ANALOG INTERFACE DESCRIPTION

The Relay 1-4 are controlled by setpoint 1-4: when the
measurement value exceeds the Set Point threshold,
the relative Relay is activated.

In particular Relay 4 can be controlled by the fourth set
point (Set Point 4) when the “Relay 4 control” is set to
“Set Point 4", or by the PHD-4 status when ”Ready 4
control" is set to “Ready”.

In the first case (Relay 4 control = Set Point 4) the
Relay 4 is activated when the measurement value
exceeds the Set Point 4 threshold.

In the second case (Relay 4 control = Ready) the Relay
4 is activated when the PHD-4 is ready for the
measurement.
As a default condition, “Relay 4 control” is set to
“Ready”.

The output of each relay is present on the auxiliary
connector (see the figure "Electrical Connections
Table").

A digital input on pin 4 controls the zero function of the
PHD-4 from remote: when the input is open the FIXED
ZERO mode is activated (indication FZ on the display);
when the input is closed the AUTOMATIC ZERO mode
is activated (indication AZ on the display).

NOTE

To use the remote zero control, or analog remote
control menu COMMUNICATIONS/REMOTE
CONTROL has to be activated.

TECHNICAL INFORMATION

29 87-900-120-01 (A)

The analog output on pins 1 and 6 provides an analog
voltage proportional to the Helium concentration. Its
output is from -1.25 V to +5 V according to the following
values:

− in HS mode: -1,25 V = -18 ppm

+5V = 10

5

ppm

− in LS mode: -1.25 V = -1800 ppm

+4 V = 106 ppm

with a resolution of 0.1 V.

For more details see the following figure.

NOTE

The analog output voltage is always related to the
measured concentration in ppm. The information does
not change if a different measurement unit is selected
from the front panel.

Communication Protocol

The communication protocol is a MASTER/SLAVE
type where:

• Host = MASTER

• Controller = SLAVE

The communication is performed in the following
way:

1. the host (MASTER) send a MESSAGE + CRC

to the controller (SLAVE);

2. the controller answer with an ANSWER + CRC

to the host.

The MESSAGE is a string with the following format:

<STX>+<ADDR>+<WIN>+<COM>+<DATA>+<ETX>
+<CRC>

where:

NOTE

When a data is indicated between two quotes (‘...’)
it means that the indicated data is the
corresponding ASCII character.

− <STX> (Start of transmission) = 0x02

− <ADDR> (Unit address) = 0x80 (for RS 232)

<ADDR> (Unit address) = 0x80 + device
number (0 to 31) (for RS 485)

− <WIN> (Window) = a string of 3 numeric

character indicating the window number (from
‘000’ to ‘999’); for the meaning of each window
see the relevant paragraph.

− <COM> (Command) = 0x30 to read the window,

0x31 to write into the window

− <DATA> = an alphanumeric ASCII string with

the data to be written into the window. In case
of a reading command this field is not present.

The field length is variable according to the
data type as per the following table:

DATA TYPE FIELD

Alphanumeric (A) 10 from blank to ‘_’ (ASCII)

− <ETX> (End of transmission) = 0x03

− <CRC> = XOR of all characters subsequent to

<STX> and including the <ETX> terminator.
The value is hexadecimal coded and indicated
by two ASCII character.

The addressed SLAVE will respond with an

ANSWER whose structure depends from the
MESSAGE type.

When the MESSAGE is a reading command, the
SLAVE will respond transmitting a string with the
same structure of the MESSAGE.
