Faults - Burkert 6510 Instructions De Service

Faults

Fault Possible cause
Valve does not Operational voltage too low or
switch: not present;
Manual override not in neutral
position;
Compressed air supply
Valves switch Compressed air supply not
with a delay, or available or insufficient;
exhaust
through the
venting ports
Valves are not in the starting
position (without current)
during pressure build-up
Insufficient venting of the
exhaust channels due to
silencers that are too small or
are soiled (back-pressure);
Impurities or foreign matter in
the pilot valve or main valve
Leaking valve O-rings between the modules
block missing or damaged;
Missing or incorrectly
positioned flat seals between
the valve and teh baseplate
INSTALLATION, INITIALISATION AND SERVICE
Correction
Check the electrical supply connections.
Ensure that the electrical power supply is the same as
that specified on the rating plate.
Set the manual override to the zero position.
Carry out the dimensioning of the compressed air
connection with volumes as large as possible (including
that of upstream pressure regulators, service units, cut-
off valves etc.)
Minimum operational pressure ≥ 2,5 bar
Carry out the dimensioning of the compressed air
connection with volumes as large as possible (including
that of upstream pressure regulators, service units, cut-
off valves etc.).
Minimum operational pressure ≥ 2,5 bar
Apply pressure to the valve block before you switch the
valves.
Use silencers or expansion channels with sufficient
dimensions. Clean soiled silencers.
Blast through the exhaust channels with polsed
compressed air, to blow out impurities. Install a new pilot
or main valve if these measures bring no improvement.
Check for leaks and for missing seals
Install the missing seals and replace damaged seals
