Installation
Note: The Remote Valve connections (described below) provides
signals to ensure that the zero and span gas valves will be
controlled synchronously. If you have the –C Internal valve
option—which includes additional zero and span gas
inputs— the 3000RS-P automatically regulates the zero,
span and sample gas flow.
Range ID Relays: Four dedicated Range ID relay contacts. The
first three ranges are assigned to relays in ascending order—Low range
is assigned to Range 1 ID, Medium range is assigned to Range 2 ID, and
High range is assigned to Range 3 ID. The fourth range is reserved for
the Air Cal Range (25%). Table 3-4 lists the pin connections.

Network I/O: A serial digital input/output for local network
protocol. At this printing, this port is not yet functional. It is to be used
for future options to the instrument. Pins 13 (+) and 29 (–).
Remote Valve Connections: The 3000RS-P is a single-chassis
instrument, which has no Remote Valve Unit. Instead, the Remote Valve
connections are used as a method for directly controlling external
sample/zero/span gas valves. See Figure 3-4.
