Establishing Setpoint Limits
The Setpoint Limits Menu configures upper and lower limits (within the
device’s overall capabilities) for selecting a pressure control setpoint.
•
When using the front panel, if you try to command a new
setpoint that is outside of the upper and lower limits, the display
notifies you that the requested setpoint is out of range.
•
Over a serial connection, a setpoint outside
the limit will be rejected with an error.
•
When using an analog setpoint signal, setpoints that are outside
of the setpoint limits are treated as if they were at the nearest
limit. If you request a setpoint that is below the lower limit, the
controller sets the setpoint at the lower limit. Likewise, a setpoint
above the upper limit sets the setpoint at the upper limit.
!
Warning:
Pressure controllers that have non-zero
lower setpoint limits cannot be set to stop flow
until the lower limit has been cleared.
