4.9 Program Analog Outputs
Outputs 1– 3 are CAT or VAT types used for control and/or retransmission. Remaining outputs are DAT
types used for control only. The relay outputs must be present to use these DAT outputs.
If the instrument will be used for control, program the loops first. See Program Control Loops in Section
4.8.
Select an analog output to program.
To change an analog output's hardware from CAT to VAT, see Section 9.3.
