Solution

The pneumatic blast control circuit
is malfunctioning.

See

Pneumatic Blast Control Circuit,

The main air regulator is stuck
open.

See

Repairing the Main Air Regulator,

(EQ600 – Kit 17C131, EQ300

– Kit 17C129).

The blast control tubing is not
connected properly.

Ensure air tubing is routed and connected
properly. See

Hose Schematic, page 42

Electric blast control circuit is
malfunctioning.

Inspect hose cable for damaged or
shorted wiring. Check battery and control
panel connections. Ensure DC power
source is 12V. Check 3A fuse inside
control panel and replace it if necessary.
Check current flow in circuit, if current
exists, replace relay (EQ5179).

The blast control is not
engaged but blasting still
occurs.

Pneumatic blast control circuit is
malfunctioning.

See

Pneumatic Blast Control Circuit,

Incorrect abrasive is being used.

Use the correct abrasive. See

Metering Valve Settings, page 16

The pot does not have a sufficient
amount of abrasive.

Refill the pot with abrasive. See

Refilling the Pot with Abrasive, page 18

.

The pot pressure setting is
incorrect.

Perform the pressure relief procedure
(see

Pressure Relief Procedure, page 8

and reset pot pressure (see

Setting Up the Equipment, page 11

).

The Auto-Vent valve does not vent
air when the pot is filled.

Make sure the Auto-Vent valve
is working. Perform the Auto-
Vent cleaning procedure (see

Cleaning the Auto-Vent Valve, page 31

The diaphragm valve is
malfunctioning.

Perform the diaphragm
flush procedure (see

Flushing the Diaphragm Valve, page 29

If flushing does not solve problem, see

Repairing the Diaphragm Valve, page 30

The blast spray pattern is
irregular.

There is blockage inside the pot or
inside the abrasive hose between
the pot and the panel.

Make sure the ball valve is closed, then
disconnect the cam-lock coupler. Open
the abrasive ball valve slightly and make
sure abrasive is flowing form the abrasive
hose. If not, follow the shut down
procedure (see

Shutting Down, page 19

Thoroughly flush the pot and the media
hose after draining media and water.
