15Latched/deadman controlWhen using the deadman control, the push-button must be held down to open or close; the motorstops as soon as the pressure is released. This type of control is used when the person operating thegate has a full view of the gate or barrier and can release the button if something is wrong.When a latched control is used, the push-button is pressed and the gate or barrier then automaticallymoves to the fully open or closed position. Latched control should be selected when automatic gatecontrol is required. Latched control may be set in either direction.• EP102 is supplied ready for deadman control.
