Important notice

In the supply line in the vicinity of the device (easily accessible), a switch marked
!
as disconnecting device as well as an overcurrent protection element (rated current
≤ 6 A) have to be provided.
!
Attention!
For the rated control supply voltage, see label at the side of the unit!

(in display mode, normal state)
Change to the menu mode, display of alarm memory (Down) /
cumulative time of alarms (Up), additional pushing of Set button for ≥ 2 s
makes a reset of the stored values
Display of MAX (Up) / MIN (Down) measured values, additional pushing
of Set button for ≥ 2 s deletes the stored values
