1 Important safety instructions
Read and follow the operating instructions
and safety instructions carefully before
starting operations! All modifications must be
done by qualified technicians!
In addition to the instructions contained in these operating instructions please pay attention to universal safety and accident prevention regulations.
Warns that disregarding of the regulations may cause electric shock.
Warns that disregarding of the regulations may cause personal injury or
damage to property.
The HYDROVAR-Smart control unit must be disconnected from the power supply before any work can be carried out in the electrical or mechanical part of the system. Installation, maintenance and repair work may only be carried out by trained, skilled and qualified personnel. Unauthorised modifications or changes to the system make all guarantees null and void. When in operation, the motor can be stopped by remote control, whereby the inverter and the motor remain under voltage. For safety reasons, the unit has to be disconnected from the power supply when carrying out work on the machinery as locking out the equipment by switching off the release mechanism or set value cannot prevent accidental starting of the motor.
The HYDROVAR-Smart works with a low voltage supply of 24VAC/DC. Nevertheless it is not allowed to touch any parts of the unit, when power supply is on. Because of the possibility to connect external voltages to the relays, at some places of the HYDROVAR-Smart, there can be dangerous voltages!
Touching these components seriously endangers life !
Before removing the HYDROVAR-SMART the system must be disconnected from the power supply. After switching off the power supply wait at least 5 minutes before starting work on or in the HYDROVAR-SMART drive head (the capacitors in the intermediate circuit of the inverter have to be discharged by the installed discharge resistors first). Please refer also to the instruction manual of the connected frequency converter and read it carefully!
6
Furthermore, care must be taken not to short circuit the neighbouring components when connecting the external control wires and that open cable ends which are not in use are isolated. The HYDROVAR-SMART control unit contains electronic safety devices which switch off the frequency drive in the event of faults, whereby the motor has zero current but remains energised and comes to a halt. The motor can also be halted by mechanical blocking. If it is switched off electronically the motor is disconnected from the mains voltage through the electronics of the frequency converter but is not potential­free in the circuit. In addition voltage fluctuations, especially power failures can cause the system to switch off itself.
Repair of faults can cause the motor to start up again!
The system is only allowed to be put into operation when it has been earthened. In addition, efficient grounding of all pipes must be ensured.
The operating instructions must be read, understood and followed by the operating personnel. We point out that we accept no liability for damage and operating disorders which are the result of non-compliance with the operating instructions.

If only one HYDROVAR-Smart pump is in operation set the Controller. If more than one pump work together via the RS485 interface (follow-up pump control), the Multicontroller must be set with the buttons Ï or Ð.
Synch. Controller: The Synchronous Controller mode is working in the same way like the Multicontroller. The only difference is, that all pumps in a multipump system are running at the same frequency. Actuator: The Actuator application is only used if you have another external controller. Then the internal controller is shut off, and the output frequency is proportional to the input signal (X1/2) 4-20 mA = 0 - f
. The outgoing signal changes with the programmed ramps 1

and 2. The functions of low water, thermal protection and external ON/OFF are still working.

If MANUAL CONTROL is selected, the parameter REQUIRED VALUE will change to MANUAL CONTROL in the main menu, where the actual frequency and the actual value is displayed (according to the JOG-MODE in the submenu). Now the frequency can be changed with the Ï and Ð buttons, and the speed of the pump will change with the fasten ramps. After selecting the right frequency, it can be saved with the standard SAVE. After a supply failure, the pump will then run with this selected frequency (depending on the parameter AUTO-START). The frequency can be changed between the set minimum and maximum frequency.
In the 1st display, there is shown the actual frequency.
NOTE:
CONFIG. FMIN will not work in this mode.
Attention
Driving the pump in a not allowed speed range can damage the motor or the inverter!

START VALUE
disabled
This parameter gives you the start value after pump stop in percentage of the required value (adjustable
between disabled and sensor range).
Example:
required value: 5,0 bar start value: 2,5 bar
If the pump system have reached the required pressure from 5.0 Bar and there is no more consumption, the Hydrovar-Smart shuts off the pump. When the consumption increases and the pressure goes down the pump will normally start. If you have selected the START VALUE at 2,5 bar the pump will start again at this selected pressure.

With this parameter CONFIG. REQ. VAL.2 you can select a independent 2nd required value.
The change between 1st and the 2nd required value can be done over the digital input, terminal X1/14 on the control card. If this input is connected to Ground, 2nd required value active.
Possible settings:
OFF: actual value 2 is not active (no change after closing the input X1/14) INT: internal required value 2, function and setting according to existing required
value.
EXT ADC-I: the required value 2 is made from the value of the current signal (4-
20mA) at the terminals X1/12, X1/10. 20mA is equal to the programmed SENSOR RANGE. If the incoming current signal is below 4mA, there will be shown an error message on the display, but no failure is indicated (failure relay is not closed). In this case the required value 2 will be 0.
EXT ADC-U 0-10V: the required value 2 is made from the value of the voltage signal
of 0-10VDC at the terminals X1/13, X1/10 (Ground)
EXT ADC-U 2-10V: the required value 2 is made from the value of the voltage signal
of 2-10VDC at the terminals X1/13, X1/10 (Ground)
Example for connection of an external 4-20mA signal for the 2nd required value:
Setting the required value2: The active required value is shown in the actual display of the parameter required value. When the 2nd required value is active (digital input, terminal X1/14, closed), in the first line,

the
terminals X1/12 (X1/10=Ground).
Note:
If the incoming current signal is below 4mA, there will be an error message on the display, but no failure is shown (failure relay is not closed). In this case the OFFSET INPUT works like external signal=0.
EXT ADC-U 0-10V: Offset will be calculated according to the voltage input of 0-

Intensity 1: -10% -1 bar (refer to the required value) Intensity 2: +30% +3 bar (refer to the required value)
The Level 1 have to be entered on the axis of the “additional input” in percent of this Second Additional input (=20%). Also proceed with the second level (80%).
Intensity 1 and 2 are depending on the Sensor range of the actual value signal. The offset of Intensity 1 is valid till Level 1. After reaching Level 1 the Required Value has no offset. Therefore you have to enter the Intensity 1 at the 0%-axis to fine the right offset value. The Required Value is valid till you reach the Level 2. After reaching Level 2, the new value, is influenced by the offset of Intensity 2. To get the right offset after Level 2, you have to enter the Intensity 2 at the 100%-axis of the additional input.
