Setting Auto/Manual Reset – The Auto/Man reset DIP switch is used to establish the “overload” reset mode of the SMP-3.
Auto/Man DIP Switch
•
Auto
Automatic Reset – The SMP-3 overload relay is set to automatic reset mode by placing the Man/Auto
DIP switch in the “ON” or “Auto” postion. In the “Auto” reset mode, an overload fault on the SMP-3
overload relay will automatically be reset after the appropriate reset delay time (See Reset Delay Times
in Chapter 4).
•
Man
Manual Reset – The SMP-3 overload relay is set to manual reset mode by placing the Man/Auto DIP
switch in the “OFF” or “Man” position. In manual reset mode, an overload fault on the SMP-3 over-
load relay can be manually reset by pressing the SMP-3 “RESET” button, the remote reset push button
(connected to the “REMOTE RESET” port on the SMP-3 overload relay), or the reset button on the
Human Interface Module (connected to the “COMM” port on the SMP-3 overload relay). However, an
overload fault can not be manually reset on the SMP-3 overload relay until the appropriate reset delay
time has expired. (See Reset Delay Times in Chapter
4 ).
ATTENTION: Do not use the automatic reset
mode in applications where unexpected or
automatic restart of the motor can cause injury to
persons or damage equipment.
Note: The Auto/Man setting only affects the reset mode of the
SMP-3 overload relay after an overload fault. All other faults
must be manually reset. Only an overload fault is auto
resettable.
