DOUBLE OPERATOR

If the weight of the up-and-over garage door is too much for
a single operator, it is necessary to fi t a system consisting of
two operators EM 51 and EM 51 Slave.
The latter has the same technical characteristics and
appearance as the EM 51, except for the absence of the
electronic control unit. In fact the EM 51 Slave only operates
as a driven operator, receiving pulses from the control unit
in the EM 51 operator.

section 4.2 of this manual.
