gate
the sld-24v-d gate operator consists of an electro-mechanical master
operator with built in electronic controls and a slave operator for the other
side that has no electronics of it’s own as it is controlled by the master
when the operator is activated by remote control or other device, it drives each
side of the gate open or closed by way of a toothed rack fitted to each gate that
engages with a gear wheel on each operator. magnets are fitted to the rack to
set the close limit of each gate, which is detected by sensors in each operator.
the open limits are set by way of an encoder in each motor that sends signals
to the control electronics as to how far each gate has travelled.
the speed of each gate is also constantly monitored by the control electronics
using the encoders so if either gate is obstructed while operating both will
reverse direction for safety.
the encoder/magnet system is extremely robust and never needs adjustment.
the master/ slave system keeps each side of the gate in sync, if two single
operators are used they can get out of sync and don’t have the same level of
safety.
