Bypass functions overview
Relay contact outputs
System Ready (1) [SYS READY]
If configured for
System Ready,
the relay
is energized when the Drive/Bypass
System is ready to be started. Two conditions must be met in order for the
System
Ready
relay to energize.
• The
Safety Interlock
input contact(s) must be closed and
• There can be no fault present in the selected mode (Drive or Bypass) of the
system.
System Running (2) [SYS RUNNING]
If configured for
System Running,
the relay is energized when the Drive/Bypass
system is running. The
System Running
relay provides an output when the motor is
running whether powered by the drive or the bypass.
System Started (3) [SYS STARTED]
If configured for
System Started
, the relay is energized when the Drive/Bypass
system is started. Three conditions must be met in order for the relay to energize.
• A
Start
command must be present,
• The
Safety Interlock
input contact(s) must be closed and
• There can be no fault present in the system. The Start command can come from
the bypass control board terminal block, the drive control panel, the bypass
control panel, or serial communications, depending on the operational mode
selected.
The System Started relay is ideal for use in damper actuator circuits, opening the
dampers only under those conditions where the system is preparing to run the motor.
Closing the dampers if the safeties open, the system faults, or when a Stop
command is issued.
Bypass Selected (4) [BYPASS MODE]
If configured for
Bypass Selected,
the relay is energized when Bypass Mode has
been selected as the method of motor control. The
Bypass Selected
relay is de-
energized when Drive Mode has been selected as the method of motor control.
Bypass Run (5) [BYPASS RUN]
If configured for
Bypass Run,
the relay is energized when the bypass is running. The
Bypass Run
relay provides an output only when the motor is running and powered
by the bypass.
The
Bypass Run
relay is de-energized when the motor is not being
run in bypass.
Bypass Fault (6) [BYPASS FLT]
If configured for
Bypass Fault,
the relay is energized when a bypass fault has
occurred or when the bypass motor overload/underload protection has tripped. The
specific nature of the fault is indicated on the bypass control panel display. The
Bypass Fault
relay is de-energized during normal operation.
