Features of the Shiva Amvaj Digital Load Controller (FN Series)
Current control based on the I2t curve
Current measurement without CT, with direct cable passage up to 25mm²
Display of current, set values and error messages
Protection against over-current, under-current and current asymmetry
Unlimited reset setting capability
Two operating modes, manual and automatic, for current control at initial start-up
8 indicators to signal
OL: Over-current (1-100A) , (0.1-30A)
UL: Under-current adjustable from zero to 1 unit below (OL)¹
A%: Current asymmetry (7-100% )
ON: Turn-on delay (0-240Sec)
OFF: Trip delay for OL and A% errors (0-20Sec)
(u)OFF: Trip delay for UL error ( 5-10Sec)
Normal: Relay status
Delay Start: Initial start time
Manual mode (0-120Sec)
Automatic mode (5Sec)
(Indicators are steady in setting state and blink in error state)
1. If UL is set to zero, under-current protection is disabled.
Device operation
The FN series digital load controller has two operating modes, which are selected in the settings section:
1. Manual mode (Han): With this mode selected, over-current is not controlled during the initial start time, which can be between ( 0-120Sec).
2. Automatic mode (Aut): In this mode, to prevent motor jamming, over-current is controlled during the initial start time, which is 5 seconds. If the current meets one of the 3 conditions below, the device detects the fault, the relay trips immediately, and the display shows the blinking text HHH:
The passing current is more than twice the device CT value: 60A model:DLFN-30A and 200A model:DLFN-100A
The current is more than 3 times the set maximum current (OL).
The current is above the set maximum current (OL) and continues for 5 seconds, even if it is decreasing, i.e. still above the set maximum current after 5 seconds.
Note: In both operating modes, during the initial start time the display shows the passing current for 2 seconds and the Delay Start countdown for 2 seconds.
