This instance V[1] is pre-configured for LV applications.
It is inactive by default because the MRU4 factory-
preset has the HV settings enabled. This means that
for an LV protection, you have to make the following
settings:
• »V[1] . Function« = “active”,
and the same for »V[2]«, »V[3]«
• »V[4] . Function« = “inactive”,
and the same for »V[5]«, »V[6]«
For the password-protection (of access level “P.2”), see
the “Security” chapter in the generic MRU4 User
Manual.
