OM13 Module Functionality
The OM13 3-wires module is supplied as an option to the Bettis SCE300 actuators. It is
possible to receive the actuator already equipped with the OM13, ordering it with the
basic feature. Alternatively, it is possible to order the OM13 as a separate kit and install
it in the basic actuator in the factory or in the field. The OM13 is an optional module
suitable to accomplish the following SCE300 actuator additional functionality:
•
120/240 V AC 1-phase, 50/60 Hz, 3-wire control for open/close operations,
without additional power supply.
NOTE:
For decommissioning instructions, please refer to the relevant section in the SCE300
VCIOM-15516-EN.
NOTE:
The OM13 command has to be provided by two separate switches for open and for close
with a delay of at least one second between the two commands, when reversing the
operation from open to close or vice versa.

WARNING
SCE300 actuator must be electrically isolated before any disassembling or
reassembling operations. Before any disassembling or reassembling operations,
please follow in detail the relevant section of the Installation, Operation and
Maintenance Manual (latest revision available).

WARNING
The electronic parts of the SCE300 actuators and all option modules can be damaged
