VLT® 8000 AQUA • • Introduction • Energy savings in a constant air volume system Compensation in the oversynchronous working range Reduces acoustic motor noise MG.83.A2.
VLT® 8000 AQUA ■ Example of application - Constant pressure regulation in water supply system The demand for water from waterworks varies considerably during the course of a day. In the night, practically no water is used, while in the morning and in the evening the consumption is high. In order to maintain a suitable pressure in the water supply lines in relation to the current demand, the water supply pumps are equipped with speed control.
■ PC software and serial communication Danfoss offers various options for serial communication. Using serial communication, it is possible to monitor, program and control one or several frequency converters from a centrally located computer. All VLT 8000 AQUA units have an RS 485 port as standard with a choice of two protocols. The protocols selectable in parameter 500 protocols are: • FC Protocol • Modbus RTU A bus option card allows higher transmission speed than RS 485.
VLT® 8000 AQUA ■ LON - Local Operating Network LonWorks is an intelligent fieldbus system which improves the possibility of decentralising control, as communication is enabled between individual units in the same system (Peer-to-Peer). This means that there is no need for a big main station for handling all the signals of the system (Master-Slave). Signals are sent direct to the unit that needs them via a common network medium.

VLT® 8000 AQUA ■ List of warnings and alarms The table gives the different warnings and alarmsand indicates whether the fault locks the frequency converter. After Trip locked, mains supply must be cut and the fault must be corrected. Reconnect mains supply and reset the frequency converter before being ready. A Trip can be reset manually in three ways 1. Via the control key [RESET] 2. Via a digital input 3.
VLT® 8000 AQUA 1 TRIP (RESET) ALARM:12 CURRENT LIMIT ■ Warnings and alarms WARNING 1 Under 10 V (10 VOLT LOW) The 10 V voltage from terminal 50 on the control card is below 10 V. Remove some of the load from terminal 50, as the 10 Volts supply is overloaded. Max. 17 mA/min. 590 . WARNING/ALARM 2 Live zero fault (LIVE ZERO ERROR) The current or voltage signal on terminal 53, 54 or 60 is below 50% of the value preset in parameter 309, 312 and 315 Terminal, min. scaling.
VLT® 8000 AQUA giving an alarm. The frequency converter cannot be reset until the counter is below 90%. The fault is that the frequency converter is overloaded by more than 100% for too long. WARNING/ALARM 10 Motor overtemperature (MOTOR TIME) According to the electronic thermal protection (ETR), the motor is too hot. Parameter 117 Motor thermal protection allows a choice of whether the frequency converter is to give a warning or an alarm when the Motor thermal projection reaches 100%.
VLT® 8000 AQUA NB!: AMA can only be carried out if there are no alarms during tuning. CHECK 103, 105 [0] Parameter 103 or 105 has a wrong setting. Correct the setting and start AMA all over. LOW P.105 [1] The motor is too small for AMA to be carried out. If AMA is to be enabled, the rated motor current (parameter 105) must be higher than 35% of the rated output current of the frequency converter. ASYMMETRICAL IMPEDANCE [2] AMA has detected an asymmetrical impedance in the motor connected to the system.
VLT® 8000 AQUA A choice must thus be made by pressing [CHANGE DATA] and choosing "Continue" + [OK] or "Stop" + [OK]. If parameters need to be changed, select "Stop"; start up AMA all over. WARNING 39 CHECK PAR. 104, 106 Parameters 104 Motor frequency fM,N, or 106 Rated motor speed nM,N, have probably not been set correctly. Check the setting and select "Continue" or [STOP]. WARNING 40 CHECK PAR. 103, 105 Parameter 103 Motor voltage, UM,N or 105 Motor current, IM,N has not been set correctly.
VLT® 8000 AQUA ■ Special conditions ■ Aggressive environments In common with all electronic equipment, a frequency converter contains a large number of mechanical and electronic components, all of which are vulnerable to environmental effects to some extent. The frequency converter should not therefore be installed in environments with airborn liquids, particles or gasses capable of affecting and damaging the elec-tronic components.
VLT® 8000 AQUA ■ Calculation of resulting reference The calculation made below gives the resulting reference when parameter 210 Reference type is programmed for Sum [0] and Relative [1], respectively. External reference is the sum of references from terminals 53, 54, 60 and serial communication. The sum of these can never exceed parameter 205 Max. reference. External reference can be calculated as follows: (Par. 205 Max. ref. - Par. 204 Min. ref.) x Ana. signal Te r Ext. ref. = m. 53 [V] Par. 310 Term.
VLT® 8000 AQUA ■ Earth leakage current Earth leakage current is primarily caused by the capacitance between motor phases and the motor cable screen. See drawing on the following page. The size of the leakage current to the earth depends on the following factors, in order of priority: 1. Length of motor cable 2. Motor cable with or without screen 3. Switching frequency 4. RFI filter used or not 5.
VLT® 8000 AQUA ■ Extreme running conditions Short circuit VLT 8000 AQUA is protected against short circuits by means of current measurement in each of the three motor phases. A short circuit between two output phases will cause an overcurrent in the inverter. However, each transistor of the inverter will be turned off individually when the short circuit current exceeds the permitted value.
VLT® 8000 AQUA - the motor cable (type, cross-section, length screened or unscreened) inductance The natural induction causes an overshot UPEAK in the motor voltage before it stabilises itself at a level which depends on the voltage in the intermediate circuit. The rise time and the peak voltage UPEAK affect the service life of the motor. If the peak voltage is too high, motors without phase coil insulation are the ones that will primarily be affected.
VLT® 8000 AQUA ■ Acoustic noise The acoustic interference from the frequency converter comes from two sources: 1. DC intermediate circuit coils 2. Integral fan.
VLT® 8000 AQUA • The current of VLT 8152-8652, 380-480 V and VLT 8052-8402, 525-690 V, is to be derated 1%/Deg C above 40° C to 55° C maximum. ■ Derating for air pressure Below 1000m/3300 ft altitude no derating is necessary. Above 1000m/3300 ft the ambient temperature (TAMB) or max. output current (IVLT,MAX) must be derated in accordance with the diagram below: If VLT 8000 AQUA is operated at temperatures above 45ºC (113°F), a derating of the continuous output current is necessary.
VLT® 8000 AQUA ■ Derating for running at low speed When a centrifugal pump or a fan is controlled by a VLT 8000 AQUA frequency converter, it is not necessary to reduce the output current at low speed because the load characterstic of the centrifugal pumps/fans, automatically ensures the necessary reduction. For CT (Constant Torque) applications, consult motor manufacturer for motor derating guideline based upon operating load and duty cycle.
VLT® 8000 AQUA ■ Air humidity VLT 8000 AQUA has been designed to meet the IEC 68-2-3 standard, EN 50178 pkt. 9.4.2.2/DIN 40040, class E, at 40°C. See specifications under General technical data. Efficiency of VLT 8000 AQUA (η VLT) The load on the frequency converter has little effect on its efficiency. In general, the efficiency is the same at the rated motor frequency fM,N, regardless of whether the motor supplies 100% of the rated shaft torque or only 75%, i.e. in case of part loads.
VLT® 8000 AQUA ■ Mains supply interference/harmonics A frequency converter takes up a non-sinusoidal current from mains, which increases the input current IRMS. A non-sinusoidal current can be transformed by means of a Fourier analysis and split up into sine wave currents with different frequencies, i.e.
