Parameter number Parameter Name Default Value Parameter Description
22-50 Under Pressure Function Off This parameter configures
the Under Pressure
Function. The Under
Pressure Alarm/Warning is
issued when the system
pressure falls below the
Under Pressure Limit
[22-52] for longer than the
Under Pressure Time Delay
[22-51].
22-51 Under Pressure Delay Time 30 s This parameter specifies the
time between detection of
an Under Pressure event
and when the action
defined in Under Pressure
Function is issued.
22-52 Under Pressure Difference 10% Under Pressure Difference
is the difference between
the setpoint and the actual
pressure that will trigger
the Under Pressure
Function. This value is set as
a % of Maximum
Reference/Feedb. [20-14]
5-40 Function Relay Relay 1: No Alarm
Relay 2: Running
This parameter configures
Relay 1 and 2 functions.
This array parameter allows
configuration of both relays.
See Programming the
controller for details on how
to navigate the array
parameter screen . [0] =
Relay 1, [1] = Relay 2
5-41 On Delay, Relay Relay 1: 0.01s
Relay 2: 0.01s
This parameter configures
Relay 1 and 2 On Delay
Time. This array parameter
allows configuration of both
relays. See Programming
the controller for details on
how to navigate the array
parameter screen . [0] =
Relay 1, [1] = Relay 2
20-00 Feedback 1 Source Analog Input 53 Feedback source for the PID
controller, transducer input
source.
20-13 Min Reference/Feedb. 0.0 Minimum feedback value
for the transducer.
20-14 Max Reference/Feedb. 300.0 Maximum feedback value
for the transducer.
3-41 Ramp 1 Ramp Up Time 10 s Ramp up time (0 to full
speed). Increasing this time
will produce a slower ramp
up.
3-42 Ramp 1 Ramp Down Time 5 s Ramp down time (full
speed to 0). Increasing this
time will produce a slower
ramp down.
