PPC3™ OPERATION AND MAINTENANCE MANUAL

2.2 SITE REQUIREMENTS
The PPC3 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 PPC3 can also be mounted in a
standard 19 in. rack using the optional rack mount kit.
Minimizing the distance between the PPC3 and the device or system under test will enhance control
performance and reduce pressure setting times.
Ready access to the PPC3 rear panel should be considered to facilitate making and breaking
pressure connections.
Pneumatic and RS-232 connections to RPM4s should be considered if RPM4s are to be used as
external reference pressure measurement devices (see Section 2.3.7).
The Self Purging Liquid Trap (SPLT), if used, should be mounted vertically at the low point of the
connection between the PPC3 TEST(+) port and the test (see Section 2.3.8.1).
If you are using a G15K or BG15K Q-RPT with a Dual Volume Unit (DVU), its location and
connections should be considered (see Section 2.3.8.2).
Support facilities required include:
• An electrical power source of 85 to 264 VAC, 50 - 60 Hz.
• A continuous, regulated pressure supply of clean, dry, non-corrosive gas at PPC3 maximum
control pressure + 10 % (at least 70 kPa (10 psi) in the case of a BG15K Q-RPT) to be connected to
the PPC3 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.
2.3 SETUP
2.3.1 PREPARING FOR OPERATION
To prepare PPC3 for check out and operation:
Remove the plastic caps from the PPC3 rear panel pressure connections.
Remove the protective plastic sheet from the front panel display.
Install the rubber feet caps onto the bottom case feet, if desired.
Familiarize yourself briefly with the front and rear panel (see Section 2.3.2).
Then proceed with Sections 2.3.3 to 2.3.11
