  • Page 4: Overview Of Type Ev2S-Can Electronic Amplifier

    Overview of type EV2S-CAN electronic amplifier Proportional amplifiers actuate proportional solenoid valves by converting an input signal into a corresponding control current. The EV2S-CAN proportional amplifier is available for direct mounting onto a solenoid valve as a plug amplifier. It is suitable for controlling proportional single-action and twin solenoids. The influences of temperature and power supply are compensated for by the feedback measurement at the valve outputs, enabling the valve to behave consistently accurately.

    5.2 Operating instructions CAN communication In a CAN network with 11-bit identifier protocol, the type EV2S-CAN proportional amplifier can be connected according to CAN 2.0A; with 29-bit identifier protocol, it can be connected according to CAN 2.0B. Target values sent by a master can be converted into a valve current. An analogue sensor can also be read and the values sent to the master via CAN bus.
  • Page 13 Display The two-digit seven-character display shows the abbreviation for the selected menu item or the value of the selected user parameter within the menu structure. Values ranging from -9,999 to +99,999 may be shown. User parameters with values ranging from 0 to 99 are shown directly in the character display. In order to be able to display values greater than 99, the values are shown individually in thousands, hundreds, tens and unit blocks.
