Pressure buildup
Operation
Program sequence
Idle state: Valves 1 and 2 are closed.
Pressure buildup: The internal motor
pump increases the gas pressure
p
e
in the section by approx. 20 mbar
compared with the input pressure at
valve V1. During the test time, the
integrated diffferential pressure sen-
sor monitors the test section for leaks.
When the test pressure is attained,
the motor pump switches off (end of
test period). The release time (10-30
s) is dependent on the test volume
(max. 4.0 l).
If the test section has no leaks, the
contact is released to the control box
after approx. 30 s and the yellow LED
lights up.
If the test section is leaky or if the
pressure increase by + 20 mbar is not attained during the test period
(max. 26 s), the VPS 504 generates
a fault. The red LED is lit as long as
the contact is released by the regulator
(heat requirement).
After a short voltage drop during
testing or during burner operation, an
automatic restart is performed.
