Plug-In Amplifier VS111 Series

Installation Manual The plug-in amplifier VS111 is used to control proportional pressure, directional control, and flow valves. The amplifier is mounted directly on the proportional solenoid and secured by a central screw. It supplies a drive current for one proportional solenoid. This current is proportional to the command signal at the amplifier input. In conjunction with a proportional valve this allows an infinite adjustment of a pressure or flow rate.

Adjustment Instruction Note: For all following adjustments the potentiometer "Dither signal" has to set fully counterclockwise first. The solenoid current measured at the diagnostic output should be observed (plug-in amplifier connected to the solenoid). Please take notice of the adjustment sequence! 3. Ramp time setting

1. MIN current setting

- Adjust the response time by variation of the potentiometers "Ramp up" and "Ramp down", until the required transition behaviour is reached.

-Command signal zero (0V/0mA) -Turn the potentiometer "MIN current" clockwise, until the required valve adjustment is reached. 2. MAX current setting

4. Dither adjustment

-Command signal maximum (10V/15V/20mA) -Turn the potentiometer "MAX current", until the required valve adjustment is reached.

- Select dither frequency aac. solenoid/ valve type, with jumper B2 = 80 Hz without jumper B2 = 40 Hz - Feed in approx. 40% command signal. - Turn the potentiometer "Dither signal" max. clockwise, until an oscillating is audible within the hydraulic system.

Direction to trouble shooting The required max. current can just keep constant until the condition Max current (A) =

Supply voltage (V) 2V actual solenoid spool resistance (Ohms)*

will be keeped. This means for example, that if a solenoid spool of 24V/0.8A will be connected to the amplifier, the supply voltage should reach approx. 30V. *the resistance of the spool increases by warming for up to 40%. IA UK VS111.INDD 19.06.06 RH

Installation Manual

Installation Guide to Provision of Electromagnetic Compatibility Power Supply The utilized power supply has to comply with the EMC-standards (CE-sign, certificate of conformity). Relays and solenoids operating from the same supply circuit has to be fitted by surge protection elements. Wiring Cable The wiring cable between the control cabinet and the valve has to be shielded. The wiring has to be installed from a 7wire cable that utilizes a common shielding and a cross section of min. AWG17. The capacity should not exceed a value of approx. 130pF/m (wire/wire). The maximum cable length is 50 m. No power current lines may be placed in parallel to the valve's wiring cables. The cable shield has to be connected to the connector pin 2. The earth pin of the connector has to be installed as separate wire within the cable to the cabinet and should there be connected to the Earth Ground potential.
