IDEC SmartRelay Manual 172
Viewing the MI, MN and OT values
• IDEC SmartRelay Base with display unit: You can open
the parameter assignment mode when the system is in
RUN to view the actual values of MI, MN and OT.
• IDEC SmartRelay Base without display unit: In
WindLGC, you can use the Online Test to read these val
-
ues (for further information, see Chapter 7).
Limit value of OT
The value of the operating hours in OT are retained when
you reset the Operating hours counter with a signal at input
R. The Operating hours counter OT continues the count as
long as En = 1, irrespective of the status at the reset input R.
The counter limit of OT is 99999 h.
The Operating hours counter stops when it reaches this val-
ue.
In programming mode, you can set the initial value of OT.
The counter starts operation at any value other than zero.
MN is automatically calculated at the START, based on the
MI and OT values
(Example: MI = 100, OT = 130, the result is MN = 70).

MI is the configurable time interval. Its permissible range of
values lies between 0 and 9999 hours.
