NOTES:
1.
If Output 2 is set to be a relay/SSR drive/solid state
output, it may be a control output (COOL) 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 set to be a relay/SSR drive/solid state
output, it can only be 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 4888. 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 Controller’s hardware configuration (change of input/output
type, alarm/recorder output added/removed etc.). The Controller software
depends upon this code to ensure that the Controller operates correctly.
This code may be viewed as a Read Only display in Operator Mode (see Volume
