ABB MS116 - Motor Current Setting Procedure; Overload Trip Test; Restart after Tripping

MANUAL MOTOR STARTER GUIDE
APRIL 19 51/80
6.3 Motor current setting procedure
Set the current on the scale of the manual motor starter current setting with the help of a screw-driver. Use a screw-
driver on the circuit-breaker scale to set the rated current (setting current) I
e
.
Figure 31: Motor current setting.
6.4 Overload trip test
The following figure show the procedures for testing the overload tripping of manual motor starter:
1. Insert a slot screwdriver (e.g. 0.5 x 2.5 mm) into the test opening and gently push it backwards.
2.
Result - when the manual motor starter trips to “TRIP” the test has been passed (the MS116 trip from “I” to
“0”).

6.5 Restart after tripping
When the manual motor starter trips, the rotary switch goes to the TRIP position to indicate tripping. The tripping of
the manual motor starter can optionally be signaled (using an accessory). This can also be done electrically with a
signaling switch.
Restarting (after correcting the cause of the error / determining correctness) again takes place directly at the
switch. The rotary actuator must first be set to “O” before switching it on again in order to set the mechanism back
to standby. Then it cannot be turned on.
