PVEH - proportional module, high. Performance like PVEA but with fast reaction time. Main features of PVEH: - Inductive transducer, - Integrated pulse width modulation, - Low hysteresis, - Fast reaction time, - Hirschmann or AMP connector, - As option with directional indicator (DI), - Fault monitoring with transistor output for signal source, - Low electrical power, - No set-up procedure.
Active fault monitoring - A delay of 500 ms (PVEA: 750 ms) before anything happens. - The solenoid valve bridge will be disabled and all solenoid valves will be released. - An alarm signal is sent out through the appropriate pin connection. - This state is memorized and continues until the system is actively reset (by turning off the supply voltage).
Passive fault monitoring - A delay of 250 ms (PVEA: 750 ms) before anything happens. - The solenoid valve bridge will not be disabled but still control the main spool position. - An alarm signal is sent out through the appropriate pin connection. - This state is not memorized. When the erroneous state disappears, the alarm signal will turn to passive again. However, the signal will always be active for a minimum of 100 ms when triggered.
