Once the energy meter has been configured, do the following steps in the unit controller:
From Main Menu, go to View/Set Unit
Commission Unit
Configuration
Unit
Set Energy Mtr = Nemo D4-L or Nemo D4-Le
The energy meter option integrates the current limit function, which allows the unit to limit its
capacity in order not to exceed a pre-defined current setpoint. This setpoint can be set in the unit
display or can be changed from an external 4-20 mA signal.
The current limit must be set according to the following instructions:
From Main Menu, go to View/Set Unit
Power Conservation
The following settings related to current limit option are available into the menu:
Unit Current
Displays the unit current
Current Limit
Displays the active current limit (which can be given by an external signal if unit is in network mode)
Current Lim Sp
Set the current limit setpoint (if unit is in local mode)
7.3 Rapid Restart (Optional)
This chiller can activate a Rapid Restart (optional) sequence in reaction to a power failure. A digital
contact is used to inform the controller that the feature is enabled. The feature will be configured in
the factory.
Rapid restart is activated under the following conditions:
The power failure exists for up to 180 seconds
The unit and circuit switches are ON.
No unit or circuit alarms exist.
The unit has been running in the normal Run state
The BMS Circuit Mode setpoint is set to Auto when the control source is Network
If the power failure is more than 180 seconds, the unit will start based on the setting of the Stop-to-
Start cycle timer (minimum setting of 3 minutes) and load per standard unit without Rapid Restart.
When Rapid Restart is active, the unit will restart within 30 seconds of power restoration. The time
to restore full load is less than 6 minutes.
