SJE®1 VFDC-3000 Controller User Manual

Warning: Users must read this manual and understand controller operation before changing any settings.

Entering incorrect settings may result in damage to equipment.

If the controller was shipped pre-installed in a control panel, some default values may have been changed

at the factory in order to properly test the control panel operation. The user must adjust the settings to the

requirements of their particular installation

The user should always keep a record of the settings before making changes in case there is a need to

revert to previous settings. The user should also record all settings changed for use in programming a new

controller in case a replacement is ever needed.

Always thoroughly test controller operation in the installed configuration to verify user settings.

INTRODUCTION & SPECIFICATIONS

Congratulations and thank you for your purchase of the VFDC-3000 controller. This manual explains the

features and operations of the controller which was designed to operate up to 3 pumps in a constant pressure

application. The controller automatically adjusts pump speed and the on and off pump sequence in response

to changes in the system pressure. When used to control the system pressure, a 4-20mA pressure transmitter

is connected to the input. The controller features a rotary selector knob in addition to left shift and escape

push buttons for intuitive menu navigation and quick setting adjustments.

BASIC SETTINGS

Setpoint Pressure

The Setpoint Pressure is the target pressure to be maintained at the pump discharge. It cannot exceed the

maximum range of the pressure transmitter.

Sleep Frequency

The Sleep Frequency setting should be set to the frequency at which the lead pump no longer builds pressure

when operating at or near the Setpoint Pressure. The lead VFD will enter the sleep mode when the output

frequency of the lead VFD drops below the Sleep Frequency for a period of time (Sleep Time). The sleep

function is suspended while the lag VFD is in operation.

Sleep Delay Time

Set the Sleep Delay Time to the amount of time that the lead VFD will wait before entering sleep mode after

the output frequency drops below the Sleep Frequency. Note: If the system cycles on and off too frequently,

try the following: increase the Sleep Delay Time, lower the Sleep Frequency, or increase the Lead Pump Start

Differential Pressure. A combination of changes of all three settings may be necessary. If the lead VFD does

not enter sleep mode when there is no flow of water in the system, the Sleep Frequency must be increased.

Minimum Frequency

The Minimum Frequency should be set to the minimum output frequency that the pumps should be allowed to

run. Contact your pump manufacturer to obtain the pump safe operation ranges.

Maximum Frequency

The Maximum Frequency should be set to the maximum output frequency that the pumps should be allowed

to run. Warning! Running above the motor nameplate frequency (50Hz or 60Hz) may cause damage to the

pump. Contact your pump and motor manufacturer for operation above the rated frequency on the nameplate.

Lead Pump Start Differential Pressure

The Lead Pump Start Differential Pressure is the amount of pressure drop from the Setpoint Pressure, at

which the lead VFD will wake from sleep and run to maintain the system pressure. The lead pump will start if

the pressure drops below the Setpoint Pressure less the Lead Pump Start Differential Pressure. Example: If

the Setpoint Pressure is 40 PSI and the Lead Pump Start Differential Pressure is -5 PSI, the lead pump will

start when the pressure drops below 35 PSI.

Lag Pump Start Differential Pressure

The Lag Pump Start Differential Pressure is the amount of pressure drop from Setpoint Pressure, while the

lead VFD is running full speed before a lag VFD is started. The lag VFD speed is controlled to maintain

pressure while in operation. The lead VFD will not be allowed to enter sleep mode while a lag VFD is running.

Lag Pump Stop Differential Pressure

The Lag Pump Stop Differential Pressure is the amount of pressure over the Setpoint Pressure before the lag

VFD is stopped.

Alternation

The Alternation setting can be adjusted to alternate the operation of Pump 1, 2 and 3 or to keep Pump 1, 2 or

3 as lead pump.

Alternation Time

The Alternation Time is the total accumulated run time of the current lead VFD, before the lead operation is

passed to the next available VFD in the sequence. Alternation Time is intended to even out the wear of the

pumps by transferring the lead operation after a set period of run time. Set to “0” to disable alternation.

Low Pressure Alarm

The Low Pressure Alarm is used to notify the user and stop the system if system pressure is unable to be

maintained at an allowable pressure. The Low Pressure Alarm can be set up to automatically reset after the

Low Pressure Alarm Reset Delay Time, or to require a manual reset by the user.

• Low Pressure Alarm

The Low Pressure Alarm setting should be set to the pressure below which the controller activates the Low

Pressure Alarm after the Low Pressure Alarm Delay Time.

• Low Pressure Alarm Delay Time

The Low Pressure Alarm Delay Time setting should be set to the amount of time that the system is below

the Low Pressure Alarm pressure, before the Low Pressure Alarm flag is set and pump operations are

SJE®6VFDC-3000 Controller User Manual

SJE®7VFDC-3000 Controller User Manual

suspended.

• Low Pressure Alarm Reset Delay Time

The Low Pressure Alarm Reset Delay Time setting should be set to the time after a Low Pressure Alarm

flag is set until the system automatically resets. Upon automatic reset, the Low Pressure Alarm flag is

cleared and normal operation of the controller resumes. If a manual reset of the Low Pressure Alarm is

desired, set the Low Pressure Alarm Reset Delay Time to “0.0”.

High Pressure Alarm

The High Pressure Alarm is used to notify the user and stop the pumps if the system pressure exceeds the

High Pressure Alarm setting. The High Pressure Alarm automatically resets after the system pressure drops

below the High Pressure Alarm setting.

Low Water Delay Time

The Low Water Delay Time setting should be set to the amount of time after a Low Water input is active,

before the Low Water flag is set and pump operations are suspended.

SJE®8VFDC-3000 Controller User Manual

Acceleration

Set the Acceleration setting to the rate at which the output frequency will increase during normal operation.

This rate is based on the time the VFD would take to accelerate from 0 Hz to 60 Hz. Example: If the pump is

required to accelerate from 30 Hz to 60 Hz in 1.5 seconds the Acceleration rate should be set to 3 seconds.

Deceleration

Set the Deceleration setting to the rate at which the output frequency will decrease during normal operation.

This rate is based on the time the VFD would take to decelerate from 60 Hz to 0 Hz. Example: If the pump is

required to decelerate from 60 Hz to 30Hz in 1.5 seconds the Deceleration rate should be set to 3 seconds.

Thrust Bearing Frequency

The Thrust Bearing Frequency should be set to the frequency at which the initial acceleration rate changes

to the acceleration rate of normal operation. This is typically used on submersible type pumps, where the

manufacturer requires a faster acceleration rate from a stop to the Thrust Bearing Frequency for proper thrust

bearing operation. Set to 0.0 to disable the thrust bearing function. Note: If the Pipe Fill function is used at a

lower frequency, it will take precedence over the thrust bearing function.

Thrust Bearing Acceleration

Set the Thrust Bearing Acceleration to the rate at which the pump should accelerate from a stop to the Thrust

Bearing Frequency. This is typically used on submersible type pumps, where the manufacturer requires a

faster acceleration rate for proper thrust bearing operation.

Pump 1~3 Overload Amps

The Pump 1~3 Overload Amps setting should be set to the full load amp rating of the pump for non-

submersible applications and to the service factor amps for submersible pumps.

Pump 1~3 Motor Voltage

The Pump 1~3 Motor Voltage setting should be set to the voltage on the nameplate of the pump. This setting

cannot exceed the incoming voltage measured at the control panel input power terminals.
