VMU-O module configuration mask
The system will automatically display the information concerning the source base module
(VMU-C EM or VMU-M EM) and the location of the VMU-O module within the system.
Indicate for each of the two outputs (Output1 and Output2) the function to be applied
(Remote, Alarm, Clock):
VMU-O usage modes

Remote : Activation and deactivation are performed through a special command
sent by the operator through VMU-C.

Alarm : The output is associated with an alarm condition coming from local VMU
modules connected by local bus to the target VMU_O (i.e. temperature setpoint
on the VMU-P): in this case the alarm management is made locally by the VMU-
M master This selection also allows to define the initial state of the relay
(Normally closed or Normally open).

Clock : Activation and deactivation are carried out at the time set in VMU-C.

Global : The output is associated with an alarm condition coming from VMU-C (i.e.
an Energy meter voltage setpoint): in this case the alarm management is made
remotely by the VMU-C. This selection also allows to define the initial state of the
relay (Normally closed or Normally open).
