Transducer Range: When using a pressure transducer, this parameter sets the range of the trans-
ducer connected to the drive.
• 100 to 300 psi
• Default = 100 psi
Primary Setpoint: When using a pressure transducer, this parameter sets the target pressure the
drive will maintain.
• 5 psi to
Transducer Range
–5
• Default = 50 psi
Drawdown: The drawdown function allows the drive to regulate to the Pressure Setpoint and
remain off until pressure drops to the
Cut In Setpoint
.
• Disabled/Enabled
Cut In Setpoint: This parameter sets the low pressure limit before the drive restarts when using the
Drawdown function.
• 5 psi to
Primary Setpoint
–1
• Default = 40 psi
Proportional Gain: This setting determines transducer input sensitivity. A greater value provides
more sensitivity. However, if set too high, the system may create an output frequency oscillation.
Integration Time: This setting determines response time to transducer input. A greater value pro-
vides slower response and may cause oscillation of output frequency.
Surface Application System Response Settings
The FE Connect app provides the option to refine system response
beyond the
Slow
,
Medium
, and
Fast
choices provided by the DIP
switches.
1. If pressure regulation performance is not acceptable using one
of the pre-configured settings, use the FE Connect app to con-
figure a
Custom
system response.
2. Test the Proportional Gain value by opening the shut-off valve
after the pressure sensor and monitor the initial pressure.
•
If the initial pressure is +/-15% of the setpoint pressure, the
P value is good.
• If the initial pressure is less than 15% of the setpoint
pressure, increase the P value.
• If the initial pressure is more than 15% of the setpoint pressure, decrease the P value.
3. Test the Integration Time (I) value by opening the shut-off valve after the pressure sensor and
monitoring the stabilizing pressure.
•
If the pressure stabilizes within 10 seconds, the I value is good.
• If the pressure stabilizes after 10 seconds, reduce the I value. If the minimum I value is
reached, reduce the frequency range.
