AquaBlock 2 - Maintenance
22
PREVENTIVE
MAINTENANCE
† In the event of a system malfunction,
a determination of the probable cause
should be made using the "Trouble-
shooting Guide" in this section. The
failed sub-assembly can then be easily
replaced following the instructions below.
† Periodically inspect tubing and fittings
for wear or damage, and replace as re-
quired.
NOTE
General
Overall cleanliness of the AquaBlock 2 is key to
maintaining voltage blocking capabilities and help-
ing to ensure trouble free operation. The internal
and external surfaces of the AquaBlock 2 should
be cleaned periodically for efficient operation.
1. Coating material should be cleaned from the
inside of the AquaBlock 2 enclosure immediate-
ly. Conductive coatings left on surfaces effect
system operation and may lead to poor system
performance.
2. Ensure proper operation of interlocks – High
Voltage, AquaBlock 2 pneumatic circuit, etc.
4-Way Shuttle Assembly
The main components of the 4-Way Shuttle As-
sembly include the rodless cylinder, and the four
(4) pairs of quick disconnects. The rodless cylinder
is not field repairable. Care should be taken to
ensure their cleanliness and proper use and they
should provide a long service life. Should service
or repair be required the rodless cylinder should
be returned to Ransburg in Angola, IN. The quick
disconnects are serviceable. (See "Procedure
for Rebuilding Male and Female AquaBlock 2
Disconnects" in the "Maintenance" section.)
1. Coating material should be cleaned from the
face of the rodless cylinder immediately. Care
should be taken to ensure that any cleaning sol-
vents used do not enter any of the openings of
the rodless cylinder.
2. Ensure proper alignment of quick disconnects
at each end of the shuttle stroke. Jack screws
are provided for fine adjustment when required.
(See "Adjustment Procedure" in the "Maintenance"
section.)
3. Inspect inlet and outlet tubing for abrasion or
wear.
Cylinder Assembly
The cylinder/reservoir assembly [60] has a double
piston. The pistons are fed by the 4-way shuttle
assembly. This sub-assembly can be easily re-
placed for repair or preventive maintenance. The
cylinder/reservoir assembly should be repaired
or replaced approximately every 6 months. This
frequency may be increased in applications using
abrasive coatings.
Removal
1. Thoroughly flush the coating material from the
system and relieve the fluid pressure.
2. Disconnect the fluid tubes at each end of the
cylinder/reservoir.
3. Disconnect the pneumatic end of stroke signal
lines from the cylinder/reservoir center section.
4. Loosen and remove the two (2) mounting
screws [29] and remove the assembly.
Disassembly
(Refer to Figure 6)
1. Drain as much purge material as possible from
each reservoir.
2. Place the assembly’s mounting plate [2] on a
flat surface and unscrew each reservoir [10] using
the RPM-419, wrench assembly.
3. Loosen both jam nuts [6] at either end of the
connecting rod [5] and unscrew each piston as-
sembly.
