controlled synchronously. If you have the –C Internal valve

option—which includes additional zero and span gas inputs—

the 3000T 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 3010TAC 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 3-5.
