Wiring a Position Retransmit
CAUTION
For proper operation, maintain signal po and -
respectively.
To connect:
1. Strip the insulation at the end of the wires. Strip
approximately 1/4” (6.35 mm) of the insulation at the end of
wires (wire size 14 to 28 AWG, 2.5 mm
2
to .08 mm
2
).
2. Connect the + ⁄ - terminals from the 4-20 mA Out to the
position retransmit input signal: + to + and - to -. See
Figure
8 on page 22.
To troubleshoot retransmit connections:
Ensure that the retransmit circuit has a minimum voltage
of 10 V (maximum 30 V).
Ensure the minimum AO current is 3.2 mA. If the module
loses power and the AO circuit remains powered, the
AO signal will be 3.2 mA.
Wiring Guidelines
Guidelines for a successful implementation of DC current
signal, DC power, and HART
®
communication to the SVI II AP:
Compliance voltage at the SVI II AP is approximately 9
V at 20 mA, 11 V @ 4 mA. See “Determining an SVI
Positioner Compliance Voltage in a Control System” on
page
119.
Signal to the SVI II AP must be a regulated current in the
range 3.2 to 22 mA.
Controller output circuit must be unaffected by the
HART
®
tones which are in the frequency range between
1200 and 2200 Hz.
