Installation
Wiring the
Totalizer/Frequency
Output
The AT868 also provides a second output for each channel
(designated as
Output B
and
Output D
) that can be configured as a
totalizer or frequency output using the
Instrument Data Manager
(
IDM
) software. These outputs can be configured independently.
Typically, Output B is used for Channel 1 and Output D is used for
Channel 2. However, either output can be configured for use with
either channel.
Figure 1-2
below shows a wiring diagram for a typical totalizer or
frequency output circuit.
Figure 1-2: Totalizer/Frequency Output Wiring
!WARNING!
NEVER CONNECT EXTERNAL POWER TO THE
PULSE/FREQUENCY OUTPUT TERMINALS.
To wire the totalizer/frequency outputs, complete the following steps:
1.
Refer to
Figure 1-5
on page 1-16 for the location of the terminal
blocks and wire the totalizer/frequency outputs as shown. Then,
secure the cable clamp.
Note:
Outputs 1 and 2 in the wiring diagram correspond to Outputs
B and D in the AT868 software.
2.
Do one of the following:
•
Proceed to another section to continue wiring the AT868.
•
Reinstall the plastic shroud, replace the front cover on the
enclosure and tighten the screws.
