These features would be useful if an operator wanted to “lock” the door in a particular position with the use of
external switches connected in parallel with the directional switch.
For safety reasons, these directional
buttons have a priority built into the SC-325& SC-650 Controllers in case one or more of the buttons are
pressed at the same time.
The “STOP” switch has first priority , the “OPEN” has second priority and the
“CLOSE” has third priority .
15.2 Sequential Switch Input Test and Manual (Single) Switch Input Test
This switch provides a conventional means of connecting a single button that
responds to each momentary press sequentially. For example, if the last movement of
the door was in the open direction and the manual input is made, the door will
attempt to close. If the last movement of the door was in the close direction and the
manual input is made, the door will attempt to open. If this single position manual
switch is used with the three position directional switch (See
Section 15.1 ), the
manual switch has fourth priority .
NOTE: This input will be reconfigured for use with the Interlock circuit if the P4
setting is programmed to anything other than zero. See SC-325 & SC-650
Controllers Owners Manual for more information on controller settings.
15.3 Timed Switch Input Test
The Timed Switch is intended for the connection of automatic door operating equipment, such as motion
detectors or floor loops. For example, the timed feature would be used when a vehicle or forklift would open
the door by means of a floor loop. After the door is opened and all safety sensors are clear, a timer would
count down and close the door automatically. In order for the timed feature to work, the door must have
initially been in a closed or stopped position. If the door was already opened by some other means, the timer
would not operate and the door would remain open.
The timed switch has priority five when the door is in the idle mode. However, if the door is in the process
of closing, the timed input will act as a safety feature that will stop and reverse the door until the door is fully
opened.
For testing purposes the Direction and Sequential Input Terminals have been removed. This was done from a
step in the trouble shooting flow chart.
