4-20mA Transducer with External 24 VDC Power
• Connect the transducer positive (Power) wire to the external source positive
[+24V]. Connect the external source negative to the VFD ACM terminal.
• Connect the transducer output (Out) wire to the ACI or AVI1 terminal. The ACI
micro switch should be in the up position. If using the AVI1 terminal, the AVI1 micro
switch should be down.
• Any shield wire should be connected to Earth ground.
• ACI Input Sel [IO–00] or AVI1 Input Sel [IO–05] should be set to the correct signal type.
•
Auto Speed Ref [SET–07]
should be set to
PID Output
,
PID F/B Source [SET–18]
should be set to the chosen input,
and PID F/B Unit [SET–19] should be set to the appropriate scale (psi, temp, flow, etc.).
0-10VDC Transducer with VFD 10 VDC Power
• Connect the transducer positive (Power) wire to the VFD +10V terminal.
• Connect the transducer output (Out) wire to the AVI1, AVI2, or ACI terminal. The
AVI1 micro switch should be in the up position. If using the ACI terminal, the ACI
micro switch should be down.
• Connect the transducer Com wire to the ACM terminal (signal ground).
• Any shield wire should be connected to Earth ground.
•
ACI Input Sel [IO–00]
or
AVI1 Input Sel [IO–05]
should be set to
0-10V
.
• Auto Speed Ref [SET–07] should be set to PID Output , PID F/B Source [SET–18] should be set to the chosen input,
and
PID F/B Unit [SET–19]
should be set to the appropriate scale (psi, temp, flow, etc.).
0-10VDC Transducer with VFD 24 VDC Power
• Connect the transducer positive (Power) wire to the VFD +24V terminal.
• Connect the transducer output (Out) wire to the AVI1, AVI2, or ACI terminal. The
AVI1 micro switch should be in the up position. If using the ACI terminal, the ACI
micro switch should be down.
• Connect the transducer Com wire to the ACM terminal (signal ground).
• Use a jumper wire to connect the ACM and DCM terminals.
• Any shield wire should be connected to Earth ground.
•
ACI Input Sel [IO–00]
or
AVI1 Input Sel [IO–05]
should be set to
0-10V
.
• Auto Speed Ref [SET–07] should be set to PID Output , PID F/B Source [SET–18] should be set to the chosen input,
and
PID F/B Unit [SET–19]
should be set to the appropriate scale (psi, temp, flow, etc.).
