Safety sensor:
On the opening side of the door:
The Safety Sensor is connected to terminals 1 and 4, with the power taken from
terminal 9, and grounded via terminal 8. The loop must have a 1K resistor in
parallel across the terminals 1 and 4, [supplied]. This MUST be fi tted in the
safety sensor, in order that the door operator monitors the condition of the cable
between the sensor and the operator. This cable is vulnerable due to the doors
movement, and in the event of an open circuit it will prevent a potentially unsafe
door opening.
The safety sensor is active, for the fi rst 70% of the door opening, it will not stop the
door opening when it has passed the 70% point, because it has been designed
so that it can ignore any obstacles, like the door reveal, or walls running in parallel
to the door opening angle.
The resistor between terminals 1 and 4 must be left in position if a safety sensor
is not used.
On the closing side of the door:
Safety sensor is connected to impulse input terminal 5. When safety sensor
detects an obstacle , it reopens the door.
Impulse input:
The closing contact drive (NO) must be potential free. The impulse device must
be installed within direct sight of the door. Maximum length of the impulse device
cable is 30 m. The total resistance of the control switch and its wiring must not
exceed 100 ohm, when switch is closed.
- Do not strip any cables for
unnecessary length. Loose wires
may cause unwanted contacts.
