VPS 504

Valve proving system for automatic shutoff valves as per EN 161, Class A and Class B

The VPS 504 may be used with any other valve whose tightness in counter-flow direction

excludes by construction a leakage in flow direction.

The VPS 504 is suitable for all DUNGS valves according to EN 161 Classes A and B.

Idle state: Valves 1 and 2 are closed.

Pressure build-up: The internal mo-

tor pump increases the gas pressure

in the test section by approx. 20 mbar

compared to the input-side pressure

applied to valve V1.

During the test period, the installed

differential pressure switch monitors

the test section for leakage. If the test

pressure is attained, the motor pump

is switched off (end of test period). The

release time (10-26 s) depends on the

test volume (max. 4.0 l) and input pres-

sure (max. 500 mbar). If the test section

is tight, the contact is released to the

automatic burner control after max. 26

s - the yellow signal lamp lights up.

If the test section is leaky or if the pres-

sure increase by + 20 mbar is not attained

during the test period (max. 26 s), the

VPS 504 switches to fault. The red signal

lamp lights as long as the contact release

by the regulator or thermostat is present

(heat requirement).

If there is a short power failure during

the test or burner operation, the test

is started again automatically.

If the pumping time < approx. 10s,

the pressure difference between the

testing system and the inlet pressure is

balanced after pumping is finished.

Operation: The internal valve of the

VPS 504 is closed.

Program sequence

Functional description

The VPS 504 operates depending on

pressure build-up.

The program module starts to function

when heat is requested.

Test is performed depending on the

burner functional procedure:

Check during pre-purge period or

Check after burner shut-down

Electrical connection

VPS 504 S01

The VPS 504 S01 is connected in

series between temperature regula-

tor and automatic burner control via

a 7-pole connector. Connector pin

assignment between burner and boiler

is performed as per DIN 4791. For

pin assignment, refer to connection

diagram.

If the heat generator is wired as per

DIN 4791, no boiler- or burner-side

rewiring is necessary for electrical

connection.

The burner female connector is con-

nected with the cable-to-cable male

connector of VPS 504 S01.

The female connector VPS 504 S01

is connected with the cable-to-cable

male connector of the heat genera-

tor.

Electrical connection

VPS 504 S03

The electrical connection of VPS

504 S03 is performed as in VPS

504 S01.

Additional switching feature of

VPS 504 S03

If a fault signal is existent on S3

(burner fault), the regulator chain is

bridged to the burner via an additional

relay in VPS 504 S03 and at the same

time the operating voltage of VPS 504

S03 is interrupted.

After eliminating the burner fault, the

valve proving system is restarted.

Only the fault signal coming

from the automatic burner

control of the burner may be con-

nected to connection S3. If you

do not observe this instruction,

persons may be injured or ob-

jects may be damaged. Therefore,

strictly keep to this instruction.

Electrical connection

VPS 504 S02

The VPS 504 S01 is connected in

series between temperature regula-

tor and automatic burner control via

a 7-pole connector.

The boiler male connector is inserted into

the female connector of VPS 504.

For pin assignment of female con-

nector VPS 504 and heat generator

male connector, refer to connection

diagram.

Switching feature: No disconnection

between operating voltage circuit and

control circuit.

Electrical connection

VPS 504 S01 SSM

Group fault alarm

The electrical connection of VPS 504

S01 SSM is performed the same way as

with the VPS 504 S01 (see page 5).

Additional switching characteristic

of VPS 504 S01 SSM

If the test path is „untight“, the VPS

switches to fault.

An additional relay in the VPS interrupts

the burner fault line S3 between burner

and heat generator. At the same time,

voltage is applied from the heat genera-

tor to S3 line and the LED H1 lights up.

The motor pump switches off, the red

fault lamp lights up. Switch-through to

the automatic burner control does not

take place.

Functional check

By opening a screw plug in test nipple

) during test period (pumping

time), leakage can be simulated and a

function check can take place.

Setting

The VPS 504 must not be adjusted

on site.

Assembly

Directly flange the VPS 504 laterally to

the DUNGS multiple actuators (mount-

ing is possible on left-hand or right-hand

side) using two 10.5 x 2.25 O rings and

four M4 x 16 self-tapping screws.

Startup

1. Check test section for leaks after

assembly.

2. Start test by using temperature regu-

lator and/or restart or by pressing the

reset button of VPS 504.

3. If the test section is tight

Depending on the length of the test

section and the residual pressure

applied, the pumping time is between

3 s and 26 s.

The release for the automatic burner

control is then given after approx. 10

s at the earliest (at small test volumes

and small input pressures) and after

approx. 26 s at the latest (at large test

volumes and large input pressures)

- the yellow signal lamp lights up.

If the test section is leaky

The test pressure is not attained.

If an exhaust gas valve is

installed in the boiler, it must

be open at the beginning of the

test.

In order to prevent functional

and leakage problems, we

recommend the use of solenoid

valves as per EN 161 Class A and

Class B.

Insufficiently shielded fre-

quency converters could

cause faults in the VPS due to

network disturbances.

Make provisions for sufficient

electrical shielding.
