Manual

During commissioning, particular attention must be paid to the correct design and realization of
the wiring. This must be checked before applying the supply voltage.
To avoid collisions, the safety devices and limit switches must be activated. All safety regulations
are to be observed.
Monitoring the fault signal (terminal 14d) is recommended.
Malfunctions can occur with the following:
• Changes to the settings made by the supplier.
• Neglecting of operating parameters (e.g. supply voltage, application of inadmissible signals on inputs or outputs,
ambient conditions, wiring, unsafe loads such as motors, contactors, relays, ohm loads, etc.)
• Faults in series-connected controls components and set points or actual values
• Faults in the subsequent hydraulic components
• Removing of solenoids connections.
3.3 Terms and conditions
Please pay attention to our general terms and conditions (available on request).
3.4 Delivery state (default setting)
The product is shipped in a ready-to-use state (default settings). After correct installation and setting of all parameters
relevant for the application, the amplifier card is ready for use.
3.5 Correct product use
The digital amplifier and controller cards “DAC-4x(A)” are used for the following applications:
• Controlling of proportional valves (namely directional control valves); with or without feedback (depending of operation
mode).
• To convert set point signals into a current signal to control one proportional valve and spool position feedback in the
aforementioned valves.
• For industrial applications only.
The operation of other inductive or resistive loads is not recommended (motors, heaters, etc.). If you are considering any
applications like this please contact HCS GmbH.
If used correctly, the safety of the user as well as the safe and proper function of the amplifier DAC-4x(A) is given.
3.6 Non-intended product use
The digital amplifier and controller cards “DAC-4x(A)” should not be used in the following cases:
• if noticeably damaged
• when the electrical connections are damaged
• if they do not function correctly
• after incorrect handling or storage
• in non-appropriate applications or environments.
In these cases, the digital amplifier and controller card must be disabled and secured against accidental restarting.
In the case of applications with critical safety requirements or where accident prevention regulations must be observed, it
may be necessary to isolate the components from the solenoids with relays in e-stop circuits. In these cases, hydraulic
and/or mechanical safety measures to stop the drive must be provided (e.g. through switching valves with position
monitoring).
During commissioning, particular attention must be paid to the correct design and realization of the wiring. This must be
checked before applying the supply voltage.
To avoid collisions, the safety devices and limit switches must be activated. All safety regulations are to be observed.
