MEC 200
LIMIT SWITCH AND VOLTAGE CUT OFF CONNECTIONS
It is recommended to fit three-phase operators with a safety device consisting of a switch to cut off power to the low voltage circuit.
Connections are in series with the limit switch common terminal (pic. 7).
The switch is activated whenever the override spanner is inserted for manual operations or the operator cover is removed.
Should the limit switches be wrongly connected so that their action opposes the normal travelling of the gate, reverse their
connections in the main board. Change over the live connections, keep the common fixed in the same terminal.

ELECTRIC MOTOR CONNECTIONS
Should it be needed to reverse the rotation
direction of the motor, change live 1 with live 2,
but the neutral is to remain fixed in its terminal
(pic. 8).
NOTE: should the motor fail to operate the gate
in case of power shortage, add an extra 12,5 μF
capacitor and parallel connect it to the electric
motor live 1 and 2 (pic. 8).
TORQUE CONTROL AND ADJUSTMENT
Mec 200 incorporates an adjustable clutch system for torque control. The system is in an oil bath and can be adjusted to the gate
weight. Adjusting is by a screw which is located on one side of the operator. A special spanner E17 is provided with the equipment
for this purpose: unscrew the locknut; the more you tighten the screw clockwise, the more you increase the operator torque; by
unscrewing it torque is decreased. Once set it to meet the site requirements, tighten the locknut hard (pic. 9).
