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.
