The PPC2+ can be installed on any flat, stable surface at a convenient height. The front feet can be
extended so that the unit can be inclined slightly for easier viewing. The PPC2+ can also be mounted
in a standard 19-in. rack mount using the optional rack mount kit.
Minimizing the length of tubing connecting the PPC2+ to the device or system to be tested will
enhance control performance and reduce pressure setting times.
Ready access to the PPC2+ rear panel should be considered to facilitate making and breaking
pressure connections.
The Self Purging Liquid Trap (SPLT), if used, should be mounted vertically at the low point of the
pneumatic system
.
Support facilities required include:
•
An electrical power source of 85 to 264 VAC, 47 to 440 Hz.
•
A continuous regulated pressure supply of clean, dry, non-corrosive gas at maximum PPC2+
range (H3) +10 % to be connected to the SUPPLY port. Lower gas pressure supply can be used
but should exceed the maximum desired test output pressure by 10 to 20 %.
•
A vacuum source of less than 1 psia (7 kPa) and with displacement of at least 3 cfm (90 lm) if
control of pressures under 3 psi (20 kPa) gauge is desired.
