AquaBlock 2 - Introduction

† If the high voltage power supply does
not have a pneumatic pressure switch,
contact your local Ransburg representative
about adding it to your power supply.
NOTE
System Electrical Current Monitor
The electrical circuit that monitors the electro-
static current that bleeds through the AquaBlock
2 is composed primarily of a microampere meter
located on the face of the cabinet. The electrical
circuit is completed by one wire connected from
the paint supply fitting to the meter and another
wire from the meter to earth ground. The meter
provides an indication of the level of current that
is passing through the AquaBlock 2 from the
electrostatic applicator. This current measure-
ment provides useful information as to the level of
contamination inside the quick disconnect shields,
contamination inside the cabinet, and abnormal
system operation such as quick disconnect (or
fluid seal) leakage, etc.
The scale on the microampere meter is divided
into three zones (refer to "Current Meter" chart).
Each time the 4-way shuttle assembly switches
there is a possibility that the current meter will
show a current reading momentarily. If the needle
on the meter returns slowly to the steady state
current or stays high, this could be an indication
of a problem situation that requires immediate
attention and potential system damage.
