To check SHOCK TIME, minimalize START TIME; to check START
TIME, minimalize SHOCK TIME.

Basic Function
A
Current (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.
B
Start 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.
C
Shock 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.
