The testing box allows the user to test and start-up proportional valves with an onboard electronic driver, with a 7-pin main connector. It is supplied with a 2 m cable, and with a 7-pin main connector for direct connection to the tested valve's driver. E-RI-TEST has two operating modalities:

Test - the E-RI-TEST, connected between the machine's central unit, and the proportional valve. During normal working it is possible to monitor the state and value of all signals from the 7-pin connector. It is not necessary to supply the valve's electronic driver.

Start-up - the E-RI-TEST, operated by multi-selectable potentiometers and switches' selectors, placed on the front panel. With this mode, it is possible to star-up the valve with preliminary movements at low speed (due to an internal reference generator). The power supply must be connected to pin A, B of the main connector.
