•
Electric installations, placing devices into operation and maintenance tasks may
only be carried out by qualified electricians with relevant training in accident
prevention and while adhering to applicable regulations.
•
Protective measures and mechanisms must correspond
•
to applicable regulations.
•
Damaged products may neither be installed nor operated.
•
The plug connectors may never be connected or removed under load.
•
Before opening the device, it must be removed from the mains and the load.

Function description
The tree-phase electronic motor starter gesis MSS PAV 3I/W1,5 can be operated
either as direct or as reversing starter with loads up to 1.5 kW. By means of phase
angle control, gesis MSS reduces the switch-on voltage and subsequently increases
it to mains voltage. The starting current is monitored, thus it can be observed
whether the motor is running at nominal speed. In this case, relay contacts bridge
the semiconductor switches to reduce power dissipation. gesis MSS switches three-
phase motor loads and monitors the motor current. gesis MSS is an AS-i slave
which takes its supply voltage directly from the AS-i bus. The device includes an
electronic motor protection which can be parameterized via the AS-i bus. Up to
three sensors with M12 connectors can be connected.

•
The base must be even and capable of supporting the weight.
•
For the mounting to the base, only the provided boreholes in the base plate of
the device may be used. Additional boreholes in other locations are not permis-
sible!
Screw the device to the supporting plate with two fastening screws M4. Use
washers.

L1 is bridged to T1 and not switched.
•
Phases L2 and L3 are switched by relays/TRIACS as follows:
−
clockwise sense of rotation:
L2 to T2 and L3 to T3
−
counterclockwise sense of rotation:
L2 to T3 and L3 to T2
