This parameter is used in CONSTANT CURRENT mode to set the RANGE of the control’s
secondary current.
The value of

.A. should be or be close to the maximum secondary current of the control. When
the control operates in different CONSTANT CURRENT modes, the RANGE has different
minimum and maximum values as shown in Table 5-8.

operator does not know the maximum value of secondary current.
To program RANGE on the EN1001 Control in CONSTANT CURRENT modes:
1. Put the control in PROGRAM mode.
2. Use SELECT to find
