Nemo SX - Multifunction control
module
Cat. N°: SXM0C1
5. GENERAL CHARACTERISTICS
(continued)
Load shedding Function:
. Allows to automatically carry out load shedding in case of power demand when a circuit exceeds a threshold.
. Function is implementable using together following Nemo SX modules:
- Multifunction Control module (cat. no SXM0C1) with DIP-switches on 0000 position (see § “Module configuration”)
- Measurement modules (cat. nos SXMM63, SXMT63, SXMMT5)
To set the different parameters it is necessary to use the Nemo SX Configuration software (available online for free)
. Procedure:
1. Assign the same address to the Nemo SX modules (Multifunction control and Measurement modules) which require to be linked
2. Connect a computer to the Modbus/Nemo SX interface or to the Mini configuration module (according to the system architecture type;
see § “System architectures”)
3. In the Nemo SX Configuration software pages adjust the parameters:
. In the dedicated page of the Measurement module:
- Threshold: value of Total active power (kW) above which procedure starts.
(default value 100 kW)
- Hysteresis: value expressed in % of the threshold under which the alarm is over and the disconnected loads are restored.
(default value 5%)
- Alarm delay (s) -
(default value 1s, min value 0 s, max. value 32767s)
:
during the activation of an alarm: is the waiting time between the threshold point and the alarm on the Nemo SX bus
during the de-activation of an alarm: is the waiting time between the hysteresis point and the alarm is deactivation on the Nemo SX bus
. In the dedicated page of the Universal control module:
- Relay normal state: the rest position of the relay; normally open (NO) or normally closed (NC).
- Relay activation: impulsive or maintained
- Relay activation time (s): used for the impulsive work method; represents the time in which the relay remains in the working position
(default
value 1s, max. value 32767s)
.
- Activation delay (s): waiting time between the alarm on the Nemo SX bus and the action done by the universal control module
(default value 0s,
max. value 32767s)
.
