SAFETY PRECAUTIONS

• Do not open cover whilst drive is in a powered state or operation.(Exposed terminals may result in electric shock)

• Do not open cover when power is off except for wiring or electrical inspection. (When power is off, residual charge may still result in electrical shock)

• During wiring or inspection work cut power, wait 10 minutes and check with electrical tester that there is no residual charge before commencing work. (When power is off, residual charge may still result in electrical shock. Do not commence work until residual charge is 30V or less)

• Do not operate the switch or drive with wet hands. (It may cause electric shock.)

• If any part of drive input or cable jacket is damaged, do not apply electricity or operate the equipment. (It may cause electric shock.)

• Do not put any stress on the input/output power or signal cables (It may damage on the cable jacket to cause electric shock.)

• Do not turn on power if drive is damaged or if any part is damaged (It may cause electric shock.)

• Do not touch the drive during powered state or several minutes after power is turned off. (Drive can generate high temperatures during operation, body contact may cause burn.)

• Do not install the equipment near the inflammable materials.

(Installation on or near the inflammable materials may cause fire.)

• When drive has any fault, cut off the input power.

(Failure to cut power may result in a fire hazard.)

• Do not leave any objects inside of drive. eg. screw, metal, water, oil, etc.

(May result in fire hazard.)

CHAPTER 4. INSTALLATION

4.1 Installation Precautions

A. Take care when handling

Drive consists of sensitive electric/electronic devices. Take care to prevent damage due to rough

handling during transportation and installation.

B. Minimize Vibration

Drive is susceptible to damage due to excessive vibration. If mounting drive directly onto motor or

piping, take measures to prevent damage due to excessive vibration.

C. Caution: Ambient Temperature

The drive has an allowable ambient temperature range of between -10 ~ 40ºC. If ambient

temperature exceeds these limits, reduce the output rating of the drive before use.

D. Install on non-flammable/ incombustible materials

The drive will generate heat and become hot during operation. To minimise fire hazards, mount the

drive on non-flammable/ incombustible materials.

E. Allow sufficient space for effective cooling

Install drive ensuring that air flow to the cooling fins is not obstructed

F. If the drive is installed off the motor, install the drive securely in upright position.

Main Power Supply Terminals

Terminal Name Description

R, S, T AC Input Connect to commercial AC input

FG Earth Connect to earth

U, V, W Drive Output Connect to Motor

Precautions on Main Power Supply Wiring

• Ensure power supply is disconnected and there is no residual charge in drive (<30V)

• Install circuit breaker (MCCB) between AC input power and drive input power terminals (R, S, T). Use a circuit breaker with a capacity 1.5 ~ 2 times larger than the rated current.

• EMI can occur due to the high speed switching of the drive and can cause radio interference on nearby electrical equipment. In order to minimise radio interference, install EMC filters between

• AC power input and the drive where required.

• AC input terminals (R, S, T) can be connected regardless of phase sequence of input power.

• When connecting output terminals of the drive to the input terminals of the motor, consider the rotation direction of the motor. In order to reverse the direction of the motor swap any two of the drive terminals (U, V, W). May also be altered through programming.

• In order to prevent damage to the drive, take care not to short circuit or earth the drive output terminals (U, V ,W).

• Do not connect static condenser or noise filter at the output of the drive as it may cause the drive to frequently trip. This may result in damage to the devices due to overheating.

• Use wires of the specified size for the drive input/output. Failure to use wires of appropriate size may result in a reduction in voltage and may result in a fire hazard due to overheating.

• Maintain wiring distance between motor and drive less than 50 metres. If drive is installed further away than this, use a motor with reinforced insulation or micro-surge filter.

Precautions on Earth Wiring

• A leak current is produced from the high speed switching of the drive so an earth connection is required to prevent electric shock.

• Maintain earth resistance within 10Ω during earthing work.

• Use wire tas shown in the table below for the earth connection.

Control Circuit Wiring Precautions

• Maintain wiring distance between pressure sensor and drive within 10 metres.

• If using a remote control with analogue signals, maintain distance between remote and drive within 50 metres.

• Separate sensor and analogue signal wires away from power wires.

• Use shielded twisted wires for signal lines of control circuit.

• GND and CG are insulated from each other. Do not connect them together.

Pressure Sensor and Low water Sensor connection

• Use pressure sensors and low water sensors approved by Vada.

Category Pressure Sensor Low Water Level Sensor

Excited Voltage DC 12V DC ±12V Pulse

• Ensure pressure sensor is installed with the correct polarity.

• Ensure that pressure sensor complies with the requirements of the table above.

Sink Mode and Source Mode

The Vada IQ Drive allows application of both sink mode (NPN: Using CG common terminal) and

source mode (PNP: Using 24V common terminal) to the input terminal logic of the control circuit.

It is possible to switch between sink mode and source mode using the selection switch within the

control board.

Communication Line Wiring

The IQ Drive supports CAN communication which is used for multiple pump control. When using

CAN communication, connect CANH (High of CAN) and CANL (Low of CAN) on the terminal block

and wire to CG using shielded and twisted wire.

When using termination resistor for connecting multiple CANs, change the switch from OPEN to SHORT.

When Using RS 485 communication, please contact Vada.

1. Switch two of the three power input wires.

2. Change the value of the Motor Rotation Direction parameter (dr-20).

D. Target Pressure Setup

• Before attempting setup, ensure that you know the correct pressure setting.

• If using linked drive operation, setup pressure on one drive will be automatically set on all drives through CAN communication.

• Select the St Group and the S Parameter. Press and hold the button for 3 seconds to enter the Pressure Setting Screen

• Use the or button to change value to desired setting.

• Press the button to apply and save setting.

• The setting will be changed and will be displayed.

• The High Pressure Alarm (Pr-70) will automatically be set to 2 bar higher than the applied pressure setting.

• If you press the button before pressing the button the setting will not be changed.

Er-04 Low Water Level Alarm - tUL

Cause

• When using a low water level sensor, the alarm will be generated when the electrode detects no water on the suction side of the pump.

• When using a low water level sensor, the drive will automatically restart when water is detected in the suction side of the pump.

• When using software low water level detection, the alarm will be generated when the pressure is maintained below the Low Pressure Alarm Level (Pr-75) for a period of time exceeding the Low Pressure Alarm Time (Pr-74).

Reaction

• Check water tank (reservoir) is full.

●Check pump for water by opening air cock.

• Press to release error and to start the pump.
