* Output 2 only
NOTES:
1.If Output 2 is a relay/SSR drive/solid state 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 a 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. retransmitted 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 Volume II, Subsection 1.11).
