S afety Functions

3 B

F unction of the Presence Impulse (Approach Side)

3 2 B
When coordinated through the CUHub, a sensor mounted to the approach side of a door will only be
active when the door is in motion. Once the door is closed, the sensor is ignored. When the CUHub
is not used, this feature can also be obtained by utilizing TB1: 8 or 9 depending on brand or model of
sensor used.

F unction of the Presence Detection (Swing Path Side)

3 3 B
When a sensor that is mounted on the swing side of a door detects an object, it will send a command
to the control to either stop or creep open. When using the CUHub this feature is active upon impulse
and is ignored once the door reaches back check. If the control has received a short signal to stop or
creep open and there is still time delay left on the control, the door will continue to open if the object
has cleared. If the time delay has expired, the door will close after all other signals have cleared.
Note: When installed as a pair, the presence detection signal will stop or creep open both doors.

F unction of the OPD

3 4 B
When an OPD (Overhead Presence Detector) sensor is mounted above the door on the swing side, it
will either keep a door in the open position, keep the door in the closed position or prevent a closing
door from reopening after a safety beam, mounted at the end of the guide rails, is blocked.

P anic Function

3 5 B
Center pivoted doors can be pushed in the opposite direction for panic egress. If one door of a pair is
pushed in the panic direction, both doors will be disabled until the door's internal spring has slowly
returned it to the closed position. Once closed, the doors will return to normal operation after the 5-
second safety delay has expired.

S afety Functions with Sensors

3 6 B
For automated pedestrian doors, safety sensors are required to meet ANSI 156.10.

F unction of Door Positioning Device (Cam Set)

3 7 B
The cam and switch assembly eases the manual opening of the door in either direction (panic or
normal), and controls the door closing in the event of power failure.
They are shown in Section titled, "Changing the Hand of the Operator" with the drive shaft in the
closed and open positions for left and right hands doors.
Note!
The cams and switches are factory set, but minor adjustments may be needed depending upon
application. The short arm micro switch and top cam are for back check and presence detection sensor
inhibit. The top cam can be adjusted to the desired back check position, which is normally 80 degrees.
The long arm micro switch on the end of the operator is for latch. The latch position is factory set to
12 degrees. The bottom and top cams are both non-handed parts. One of the two remaining switches is
used for break out, which depends on the hand of the operator. The other switch is connected to TB1:
8 & 9 and can be used as a home switch to disable a sensor at the closed position. Only the top cam
needs to be adjusted for different handing of the operator.
