NOTES:
1. If Output 2 is a relay/Solid State/SSR Drive output, it may be a control output
(COOL), an event output or an alarm output; if it is set to be a DC output, it
can only be a control output (COOL).
2. If Output 3 is a relay/SSR Drive output (it cannot be an Solid State output), it
can only be an event output or an alarm output; if it is set to be a DC output, it
can only be a recorder (i.e. re-transmitted process variable or setpoint) output.
The maximum setting available for this code is 4887. For example, the code for a
thermocouple input, DC 4 - 20mA primary output (Output 1) and relay Output 3
would be 2701.
NOTE: It is essential that this code is changed promptly whenever
there is a change to the instrument's hardware configuration
(change of input/output type, alarm/recorder output
added/removed etc.). The instrument software depends upon this
code to ensure that the instrument operates correctly.
This code may be viewed as a Read Only display in Base Mode (see Subsection
1.11).

OPTION SELECTION
This indicates the option fitted (Communications Option, Remote Run/Hold option or
no option at all). It is accessed whilst the Hardware Definition Code is displayed (see
