페이지 인쇄VPM-VC
Control unit for system leakage tests according to En 1643.
Checks tightness of the gas burner shut-off valves either before burner start or after shutdown.
Equipment: one or two gas pressure switches.
Additional pilot valves are required depending on the system
Pressure switches/valves/pilot valves are not part of the scope of delivery!

Number of operating cycles V1 > 100.000
(terminal 19 + 20, potential-free).
Further settings possible via VisionBox + parameter change:
1. Freely selectable number of operating cycles up to 6.5 million (standard
100,000)
2. Signal output with freely selectable number of operating cycles of V2,
LGV or release
3. Signal output while the test is running or while voltage is applied
4. Signal after successful switch-off
Three different program sequences can be selected via DIP switches:
1. Valve test before burner start
2. Valve test after burner switch-off
3. Test sequence with optimised valve operating cycles after burner switch-
off without additional switching cycles. In this case, only one valve will be
tested at a time after successful switch-off, --> lower power consumption
and increased valve life.
DIP switches can be used to select predefined test times of V1 and V2,
enabling optimal setting in case of different test volumes, inlet pressures
and leakage rates.
Alternatively, individual test times, even different times for V1 and V2,
can be set via VisionBox.
Depending on the test volume, different combinations can be selected
using DIP switches.
Red/green LEDs signal various information on the program and release
states or error codes.
Plug-in connection for DUNGS VisionBox. The VisionBox can be used
to access the VPM via a PC. The VisionBox is hardware and software
for VPM parameter setting. Status information and error error memory
data can be read out.
