After the power has been disabled, the switch for the 26.5 V supply is either opened or not
(depending on the setting of p0218.4) at the end of the manipulated variable inhibit time. The
default setting has been selected such that the 26.5 V valve supply voltage is disconnected
(p0218.4 = 0), thus moving the valve into the fail-safe position.
This will not be necessary if a shutoff valve is installed and actuated. This function has been
integrated for cases where a shutoff valve has been set, but is not actually connected. In
such cases, this function prevents the drive from being able to drift after a power inhibit.
p0218.1 can be set = 1 after the function has been carefully checked.
