System Stacking

To expand the ranging capability of the Product, it can be connected to one or
two other pressure controllers that support the system stacking feature. This
could potentially make a single system with up to 15 pressure ranges. When
connected, the Primary system remotely operates the Auxiliary systems. When
stacked, a fixed range can be selected from any of the other connected
controllers or have the Primary controller automatically switch ranges as it
normally would in the Fast or Auto modes.
A specific isolation valve must be installed on the test port to isolate
the test port(s) of the controllers not measuring or controlling
pressure (see setup). This valve prevents over pressurizing the other
controllers with lower range PMMs installed.

System Setup

To set up the system for stacking, extra accessory kits must be purchased:
•
•
Contact Fluke Calibration for purchase information.
To set up the system:
1. Turn the Products off.
2. Install the Product into a rack that allows access to the rear panel.
The Products can be placed on top of each other, but Fluke
Calibration highly recommends a rack installation. A rack mount kit is
available User Replaceable Parts.
To prevent injury:
•
•
3. Install the Isolation Valves as follows (repeat for each controller):
62
Electrical Connection Kit (part number 4579115) contains the necessary
electrical system connections and wires shown in Figure 20.
20 MPa (3000 psi) Test Port Isolation Valve (part number 4581266) contains
a single isolation valve and electrical connection. Does not include fittings or
hoses. See Figure 19.
Do not use the feet to prop the Products up if the systems
are placed on top of each other.
Use two handles to lift and carry the Product.
a. Connect the pressure line to the port labeled "LOW" to the TEST Port on
the rear panel.
b. Connect the pressure line to the port labeled "HIGH" to the UUT. Use
splitters where necessary to connect to the UUT. See Figure 20.
c. Connect the electrical connection from the Isolation Valve to the DRV4.
