9 Setting for force limiting
The parameter P8 (or parameters b2 / b7) represent the value for the maximum allowable static force that
the TSG door controller will allow in the door motor before it recognises the force as a blockage. Increasing
the value of P8 (or b2 or b7), will increase this allowable static force.
The kinetic energy produced by the doors, is a product of the weight of the lift doors and the set speed of the
TSG door operator (Parameters P2, P3 & P4). Refer to the information and table below for the maximum
permissible values of static force and kinetic energy under EN 81.
CAUTION:
In accordance with EN 81, the maximum static force while the door is moving must not
exceed 150 [N] (corresponds to about 15 [kg] of weight)! Any counterweights present or
springs that are used must be taken into consideration. In accordance with EN 81, the
maximum kinetic energy of the door must not exceed 10 [J]!
The kinetic energy is described by the following graph:
NOTE:
When calculating the weight of the door panel, the weights of the car and shaft door must be
included. All shaft doors have closing weights or closing springs in accordance with EN81 so
that the doors will close automatically if there is no car door behind the shaft door. These
weights or springs reduce the maximum door panel weight. As a rough estimate: 1 [kg]
closing weight corresponds to about 30 - 40 [kg] door panel weight.
