Setting the correct address on Basic drives:
• The HYDROVAR must be disconnected from power supply for at least 5 minutes before removing the top
cover!
• Use the dip-switch on the power unit. (See picture above!)
• Set the desired address for each HYDROVAR
E.g. Address 4 -> switch 1 is set to OFF
switch 2 and 3 are set to ON
• Mount the cover on the HYDROVAR and tighten the four fastening screws
• Reconnect HYDROVAR to power supply
8.4.4 Control Terminals
All control wires connected to the control-unit must be screened (See section 8.2 for recommended wire types).
External voltage free contacts must be suitable for switching <10 VDC.
NOTE
If unscreened control wires are used, signal interference may occur and could interfere with
the function of the HYDROVAR.
Do not connect the control card ground to other voltage potentials. All electronic ground terminals and GND of
the RS 485-interface are connected internally.
