Basic Function
ACurrent (Operation current value) Factory default setting㸸MAX㸦fully rihgt㸧
When the motor current exceeds the present CURRENT value, Shock Relay detects the overload
and trips.
BStart Time (Start prohibiting time) Factory default setting㸸MIN㸦fully left㸧
When the motor starts, there is a possibility that the motor current will exceed the set current
value. To prevent Shock Relay from tripping due to the spike in start current, start time is set a
little longer than motor startup period.
䠆When overload takes place in the motor startup, Shock Relay trips after the total time of start
time and shock time lapse.
CShock Time (Continuous overload time) Factory default setting㸸MIN㸦fully left㸧
When instantaneous overload occurs, motor current may exceed current set value. Shock time is
set to not activate at instantaneous overload.
