1) Ramp times effective only when 4Q operating mode is activated
2) Function available only on VT-MSPA2-2X/..
3) The function of the digital input is XOR-linked to the internally selected state
8.7 Restoring the VT-MSPA...-2X to factory settings
This function is available exclusively directly upon switching on the operating
voltage. It resets all customer-specific parameters of the set valve to the factory
settings.
The module has to be de-energized.
1. Press and hold [Set] and switch on the supply voltage.
The LEDs signal the status shown on the left.
1. After some time, the LEDs switch to the status shown on the left.
The module is restored to factory settings.
2. Release [Set].
Restoring to factory settings is completed.
