Technical Manual Switch Actuators AMI/AMS
3.3 Communication Objects current measurement
The following communication objects are available for the current measurement and counting of the
operating hours:
Nr. Function
8 Response operating
hours
8 Time to the next service
9 Reset operating hours
9 Reset service
10 Service required
11 Current value
12 Exceedance of load
13 Lower deviation of load
14 Fault current
14 Load faulty
14 Fault current/Load faulty reports a fault current and a fault of
15 Reset power meter
16 Active energy
+18 next channel
75/147 Total active energy
76/148 Value of total current
77/149 Exceedance of total
current
Table 5: Communication objects current measurement
The sizes as well as the type of the shown objects depends to the adjusted parameterization, have a
look at the relevant explanations at section 4.
There are objects for the current measurement of the single channels as well as for the total current
measurement of the actuator. It can be adjusted whether a channel shall be included to the total
current measurement or not.
