How “OIL” Activation of current overload works on ATS48 Soft Starter.
If R3 is set to AIL, then R3 is activated only if OIL is set to ALA and If the motor current exceeds an adjustable threshold LOC for a period of time longer than an adjustable value tOL.
Example: ---
Relay r3 = AIL
OIL Activation of current overload = ALA
LOC Current overload threshold = 120% of the In (nominal motor current)
tOL Current overload time = 6 sec.
In =Nominal motor current = 30Amp
If the motor current exceeds an adjustable threshold LOC (120% of 30 = 36 Amp) for a period of time longer than an adjustable value tOL (6 sec) then R3 will be activated.
