The pressure in the pulse system is indicated on the pressure gauge.
It is mounted in the Filter house next to the vacuum gauge.
Normally the pressure in the system lies between 6 up to 7 bar. This
is regulated by the control valve. The safety valve mounted on the
pulse tank is activated at approximately 10 bar.
If the pressure of 7 bar is not reached, it is possible that either the
filter of the water separator or the air filter of the compressor is dirty.
For maintenance instructions on the
waterseparator
see paragraph
7.10.
For maintenance instructions on the
compressor
see
paragraph
7.11
If inspection on the waterseparator or compressor shows no dirty
filter, it is possible that either there is a leakage in the air tubing, or
the control valve is defect. In that case replace the defective parts or
have it checked by Blastrac.
When there is pressure but the pulse system does not function, there
might be a problem in the electrical system which controls the pulsing
system. Check the wiring and the timer-unit settings. For timer-unit
settings see paragraph
7.12 .
