Access the Module Bay
After the Product is properly placed (in a standard 19 inch rack or on a bench
top) install the modules in the Module Bay. Before use, install the Pressure
Control Module (PCM) and Pressure Measurement Module(s) (PMM). See
PCM
Installation
for PCM bolt torque values.
Note
The Product rear-panel power switch can be on or off during PMM
exchange or installation.

Warning
To prevent personal injury, vent the supply pressure before you
remove the PCM.
To access the Module Bay, see Figure 1:
1. Pull out the handle (
) located directly below the numeric keypad. This
unlocks the front panel.
2. Pull the handle to slide out front panel and access the Module Bay (
).
Note
For safety, the Product automatically vents to atmosphere when the
front panel is unlatched and opened. When the front panel is open,
the system stays in the Vent mode until closed.
For service activity, see the Service Manual for detailed service
processes.
For standard operations, the system pneumatic valves are a
normally closed type. Depending on the chassis power/pressure
down process, differing levels of trapped pressure are possible.
If power is lost to the product, while at high pressure, remove
pressure supply to allow system to mostly depressurize. If possible,
power on system to perform a vent.
Before you open the front panel, remove sensitive, low pressure
devices from the test port. Use the optional Isolation Valve to
improve protection for sensitive pressure devices.
