Installation/Wiring
Building Automation Controller = Auto, OIM = Manual
A process is run by a Building Automation Controller when in Auto
mode and requires manual control from the OIM during set-up. The
Auto speed reference is issued by the Building Automation Controller
through a communications module installed in the drive. Since the
internal communications is designated as Network, [Speed Ref A Sel] is
set to “Network” with the drive running from the Auto source.
Attain Manual Control
•
Press the Hand button on the OIM.
When the OIM attains manual control, the drive speed command
comes from the OIM speed control keys.
Release to Auto Control
•
Press the Auto button on the OIM.
When the OIM releases manual control, the drive speed command
returns to the Building Automation Controller.
Building Automation Controller = Auto, Terminal Block = Manual
A process is run by a Building Automation Controller when in Auto
mode and requires manual control from an analog potentiometer wired
to the drive terminal block. The auto speed reference is issued by the
Building Automation Controller through a communications module
installed in the drive. Since the internal communications is designated as
Network, [Speed Ref A Sel] is set to “Network” with the drive running
from the Auto source. Since the Manual speed reference is issued by an
analog input (“Analog In 1 or 2”), [TB Man Ref Sel] is set to the same
input. To switch between Auto and Manual, [Digital In5 Sel] is set to
“Auto/ Manual”.
Attain Manual Control
•
Close the digital input. With the input closed, the speed command
comes from the potentiometer.
Release to Auto Control
•
Open the digital input. With the input open, the speed command
returns to the Building Automation Controller.
Auto/Manual Notes
1. Manual control is exclusive. If a OIM or Terminal Block takes
manual control, no other device can take manual control until the
controlling device releases manual control.
2. If a OIM has manual control and power is removed from the drive,
the drive will return to Auto mode when power is reapplied.
