Latched/deadman control
When using the deadman control, the push-button must be held down to open or close; the motor
stops as soon as the pressure is released. This type of control is used when the person operating the
gate 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 automatically
moves to the fully open or closed position. Latched control should be selected when automatic gate
control is required. Latched control may be set in either direction.
• EP102 is supplied ready for deadman control. Before latched control is set, the gate must
be fitted with safety buffers and the load sensor adjusted. This function must be checked.
Selection of latched operation (C33)
1. Step to channel 33 (latched/deadman control).
2. Set 3 if latched control is desired in both opening and closing movements, otherwise see channel
list.
Functional check of load sensor, safety buffer and photocell
Check that the load sensor has been correctly adjusted by braking the gate by hand so that it trips out.
It should trip when the load is abnormal.
Check that the gate will stop and reverse when safety buffer or photocell is actuated.
Closure with deadman control in the event of safety buffer or photocell error
If the safety buffer or photocell is out of order, the control panel reverts to deadman control for closing.
The gate can be closed by the deadman control if the close button is held down. This function is
optional and can be turned off. If not required, e.g. because a caretaker needs to be able to close the
gate due to failure of safety systems.
Turn off automatic reversion to deadman control (C46)
1. Step to C46 Deadman control when safety systems have failed. Set the value to 1.
2. Set the value to 0, and the gate will not close to any command while the safety system is faulty.
Direction change priority
Priority can be set. The automatic controls are normally set to Open priority. Priority does not apply to
Ö/S (Pulse command, Terminal 26).
Open priority only (C63=1):
If the gate is about to close and the Open button is pressed, the gate is stopped and begins to open. If
the gate is opening and Close is pressed, nothing happens.
Close priority only (C63=2):
If the gate is about to close and the Open button is pressed, nothing happens. If the gate is opening
and Close is pressed, the gate is stopped and begins to close.
Open and close priority (C63=3):
If the gate is about to close and the Open button is pressed, the gate is stopped and begins to open. If
the gate is opening and Close is pressed, the gate is stopped and begins to close.
No priority (C63=0):
Whether the gate is closing or opening, it is not possible to interrupt it by pressing either the Open or
Close buttons. Nothing happens as long as the gate is moving.
