coMMissioninG of M on-off controls
The M board is designed for on-off operation only.
The M commands are not self-holding. Actuator
continues to function as long as the signal is maintained
and stops when released.
Command signals are of the same voltage as the motor.
2.1
M wirinG
Make sure to power off the actuator prior to wiring the M board according to the diagrams
given above:
- Check that the open and close commands contactors are open,
- Connect the on-off commands (open/close) to the terminals 31,32 and the power supply to the PE
(earth), N (neutral) and L (line) terminals.
It is mandatory to respect the wiring diagrams to ensure a proper operation of the actuator.
Also refer to paragraphs 4, 5 and 6 for connection of optional devices (end of travel signaling
contacts, alarm board, anti-condensation heater).
Caution !
Several parts of this circuit board are supplied with 115/230 VAC.
Always power off the actuator before any wiring or maintenance operation.

M confiGuration
2.2.1
selection of on-off operation
Two switches located on the printed circuit board are used to select the “on-off” mode:
- Switches 5 and 6 positioned on B
2.2.2
Motor Direction of rotation
The switch 7 allows to set the direction of rotation :
- Switch 7 in A position: closing in clockwise direction.
- Switch 7 in B position: closing in counter clockwise direction.
2.3
settinG of open anD closeD positions
Please follow the instructions given in the “Setting of mechanical stops and travel limit switches”
paragraph of the SD range instructions for start-up (ref.TMS300SD) delivered together with
the actuator. The cams to be adjusted are the black and the white one.
2.4
reMote position siGnal (optional)
An optional potentiometer is available to get a position feedback. The potentiometer signal
is delivered between the terminals 71 and 72. The type of output signal is configurable :
2.4.1
settinG of closeD position (0%)
Drive the actuator carefully to the closed position.
Connect a milliamperemeter or a millivoltmeter on terminals 71,72.
With a screwdriver, adjust the potentiometer until reading 4mA (4-20mA signal),
0mA (0-20mA signal) or 0V (0-10V signal).
Start an actuator opening and check that the signal current/voltage increases.
2.4.2
settinG of open position (100%)
Drive the actuator carefully to the open position.
Connect a milliamperemeter or a millivoltmeter on terminals 71,72.
With a screwdriver, adjust the potentiometer until reading 20mA (0-20mA and 4-20mA signal) or
10V (0-10V signal).
