3.7 Wiring the Frequency/Totalizer/Alarm Output
The AT600 can accommodate up to two digital outputs. Each of these outputs can be configured as either a
totalizer, frequency or alarm output (see “Programming Digital Communications” on page 61 for instructions).
Each totalizer/frequency/alarm output requires a twisted pair cable. Wire the terminal block as shown in
Figure 23 on page 23 and Figure 28 below.
