6.4 Set up of the Tension Spring
MICOM SWING SPSW has a door-closing system. In order for this to function perfectly, the tension
spring must be pre-loaded. This load can be higher or lower depending upon the size/weight of the
door panel or the clients’ requirements. To load the spring:
1. Make sure the operator is not connected to the electricity supply. If it is, take the plug out from
the feed source.
2. Remove the operator arm; it will be sufficient to remove the screw that links the arm to the
motor pivot.
3. Loosen the lever screw so that this can move and turn easily.
4.
Press the ‘-TEST’ button and without letting it go, connect the electricity supply to the operator
using the 3pin plug. If it has been done correctly the letter F will appear, followed by the
number 0 on the screen.
5. On the screen the letter F appears followed by the number 0, which represents the force
loaded on the spring; value 0 is the lowest. If we press +RESET, the number will increase and
the motor will start to turn. As the motor turns the spring will be charged. The higher we
increase the value, the more the spring will be charge. Please see the following table how
value F relates to the spring force.
