The controller automatically adjusts rectifier target voltage so that each rectifier equally shares DC load. To
achieve this, the controller periodically updates a share factor in each rectifier for a faster current sharing after
a power restore. The user can manually reset this current share factor to restart current share factor
calculation again.
Note that sharing is effective only when rectifier load is more than 25% of its capacity.

To force reset of current share factor
Either:
•
On the EC500 keypad select:
Home
Settings
Rectifier Settings
Force Share Reset
•
Confirm the action to reset current share factor.
Or:
•
Connect to the EC500 via a web browser (See Ethernet Communications on page 79).
•
Go to
Settings
Rectifier Settings
Force Share Reset
.
•
Click on

•
Click on “Force Share Factor” action field to reset current share factor.
On Current Share Factor Reset, controller will restart current sharing adjustment. It may take
2
–
5 minutes to achieve less than 10% current share deviation.
RECTIFIER SLEEP MODE
User can manually put some rectifiers in Sleep Mode (i.e. shut down) in case load is less or otherwise
operation is not required. Manual Sleep Mode operation is not available when Economy Mode Operation is
enabled. In Sleep Mode, the rectifier does not produce any output voltage, though it keeps on communicating
with the controller.
➢
To force rectifier to Sleep Mode
To force any rectifier to sleep mode or to make it active
Either:
•
On the EC500 keypad Enable:

Rectifier Settings
Force SMR to Sleep
•
Then Select or Deselect individual rectifier to put it in sleep mode or to activate it.
Or:
•
Connect to the EC500 via a web browser (See Ethernet Communications on page 79).

Rectifiers can be put in Sleep mode manually only of Economy Mode Operation is disabled.
ECONOMY MODE
If Economy Mode operation is enabled, the Controller can automatically put the rectifiers in sleep mode when
the total load current is less than the total rectifier capacity.
This raises the average load on the remaining rectifiers which will then operate in higher efficiency range and
results decrease in system power consumption.
