NOTE: It is strongly recommended to connect to the analog outputs
through shielded cable. Ground shield only at one end. Shielded twisted
pair cable is recommended. It is highly recommended that the shield drain
should be grounded on the chassis of the TTC-1000. Not grounding the
shield on the TTC-1000 end may result in spurious analog values or
possible damage to the analog outputs.
In the event that the shield drain must be grounded on the opposite end of
the TTC-1000, it is recommended to install a 300V 0.47 µF capacitor for
each shielded cable or one 1.0 µF 300 V capacitor for every two shielded
cable's drain wires between the ground drain and the TTC-1000 chassis to
ensure proper operation. See section 3.10 for shield drain wire
connections.
One 1.0 µF 300V rated capacitor kit, part number 8AOMKIT0000, is available
from Advanced Power Technologies.
The analog outputs A1, A2, and A3 can be programmed for 0 to 1 mA or 4 to 20
mA. All three analog outputs are identically programmed. Consult Section 7.1 for
programming the scaling of the analog outputs.
