5.4.11 – ‘Parameters’ Menu (continued)
Shear Time
Range: 5 to 255 cycles Default: 100 cycles Scaling: 1 Type: R/W
‘Shearpin Time’ sets the number of cycles a Shearpin Current must be present before tripping. The
shearpin is active only during the running phase; not Start or Stop. The shearpin flag (P-112 / B2)
is updated even if tripping is not enabled.
«•» This parameter is not available in Bypass Operation unless a user-supplied external current
transformer is installed. (Refer to P18/B2, ‘Auto Bypass’.)
(P-92 ‘Shearpin Time 2 ’ is the 2nd parameter set counterpart of P-33 ‘Shearpin Time’.)
Ovld Level
Range: 0.5 to 1.25 x I
e
Default: 1.0938 x I
e
Scaling: 0.03125 Type: R/W
‘Start of Overload Level’ sets the level at which the on-board single phase Overload starts to
integrate. This Overload does NOT replace an overload for the motor. The overload is designed to
detect Soft Start overloads.
«•» This parameter is not available in Bypass Operation unless a user-supplied external current
transformer is installed. (Refer to P18/B2, ‘Auto Bypass’.)
(P-93 ‘Start of Overload Level 2’ is the 2nd parameter set counterpart of P-34 ‘Start of Overload
Level’.)
Ovld Delay
Range: 10 to 140 Default: 140 Scaling: 1 Type: R/W
‘Overload Delay’ sets an arbitrary delay to slow Overload integration down. The overload delay
mapping is designed primarily for protection of the thyrisors.
(P-94 ‘Overload Delay 2’ is the 2nd parameter set counterpart of P-35 ‘Overload Delay’.)
% Overload
Range: 0 to 100 percent Default: 0% Scaling: 0.39216 Type: R
‘% Overload’ is a status value showing how close the Overload is to tripping. (100 = tripped)
«•» This parameter is not available in Bypass Operation unless a user-supplied external current
transformer is installed. (Refer to P18/B2, ‘Auto Bypass’.)
