DEFAULT VALUES
Some variable features have default settings which
are enabled immediately after RESTORE DE-
FAULTS is commanded from the front panel, or a
DEFAULT command is issued over a remote bus.
The resulting default values are listed below:
Table 3.1 - Default Values
TRANSDUCER
The highest full scale range transducer in the sys-
tem used for pressure control will be an internal
transducer. This is designated as the primary
transducer, and is assigned address 0. The
pressure regulator is configured based on the pres-
sure range of this transducer, and no other internal
transducer can be of a higher pressure range than
the primary. Throughout this manual the terms
‘sensor’ and ‘transducer’ are used interchangeably
unless specifically defined.
Address
The addresses for internal transducers are as-
signed at the factory and should not be changed.
The serial number, address and range of each
transducer is recognized by the PCS 400. These
identity features are displayed on the front panel
for the transducer under LIMITS on the menu tree.
To see the active transducer identity in the display
use the key sequence: [2nd] [3] [=] .
To view information about other transducers con-
nected to a multi-range system press [+] [+] ... [+]
which will scroll the display to the next higher
address transducer, and on, through the full
transducer list. When the highest address internal
transducer of a multi-range unit is displayed the
next [+] will present the AUTORANGE screen.
To exit without affecting the current active
transducer status press [CE].
