Appendix C
Hardware Definition Code
The Hardware Definition Code is used to represent the hardware installed
(input type, Output 2 type, Output 3 type and Options); this must be com-
patible with the hardware actually installed. It can be accessed, with the
instrument in Program mode, by simultaneously depressing the DOWN and
SCROLL keys while the parameter is displayed in the lower display and the
value in the upper display. The displays will show "XXXX" (where X repre-
sents any number) in the upper display and "dEFn" in the lower display,
where:
the first (left-most) digit is input type:
1=RTD/Linear mV
2=Thermocouple
3=Linear DC mA
4=Linear DC V
the second digit is Output 1 type:
1=Relay (Limit Only)
the third digit is Output 2 type:
0=Output 2 not installed
1=Relay (Alarm Only)
the fourth digit is Output 3 type:
0=Output 3 not installed
1=Relay (Alarm only)
3=DC 0-10V (retransmit only)
4=DC 0-20mA (retransmit only)
5=DC 0-5V (retransmit only)
7=DC 4-20mA (retransmit only)
The displayed code may be incremented/decremented using the UP/
DOWN keys as required. The maximum setting available is 4117. For
example, the code for a thermocouple input, Relay Output 1 and Relay
Output 3 would be 2101. When the code is first altered, the code display
will flash, until the desired value is displayed and confirmed by pressing the
RESET key.
