SERVICE REMINDER INDICATION
When the Smart Controller has exceeded the
selected Service Cycle Limit, the Service Cycles
LED will begin flashing to indicate that service is
needed. See Section 6.1 P10 and P11 for a
description of the Service Cycle Reset and
Service Reminder.
5.4 Safety Beam
The Smart Controller uses an invisible safety beam
near the bottom of the automatic doors to prevent the
door from closing on an object that has moved into
position under the door. If an object interrupts this
beam of invisible light, the door will stop and the
Door Obstruction Light in the controller display will
light. The door may then proceed to open depending
on the setting of switch SWX1.
If SWX1:1 is “On”, the door will proceed to open to its full open
position. If SWX1:1 is “Off”, the door will stop and await a command to either continue opening or to close.
See Section 12.1 for the location of SWX1 on the controller PCB 154 circuit board.
5.5 Leading Edge Switch
The door is equipped with a Leading Edge Switch. This switch works in conjunction with the safety beam.
Its function is to provide a back-up for the safety beam. If anything comes in contact with the leading edge of
the panel, the door will react in the same manner as the safety beam.
5.6 Home and Safety Limit Switches
HOME SWITCH
The RollSeal automatic doors contains a Home limit switch for determining the “Home” or full open
position of the door. When the door is fully opened the Home limit switch is triggered to stop the door.
At this position the actual reading on the Display indicator will be zero (0). The Smart Controllers also
use the operation of the Home switch to verify the position of the door.
SAFETY SWITCH
An additional safety feature of the automatic doors is a Safety switch which will stop the door if the
Home limit switch does not stop the door at its full open position. The Safety switch is an emergency
override. Once the door has made contact with the Safety switch, the motor’s drive unit is completely
disabled. At this point the door must be manually reset to return to normal operation. In most cases this
can be done by manually releasing the brake on the motor. This will allow the door to drift below the
Safety switch.
6 SC-325 and SC-650 Initial Setup
6.1 Program Mode
Settings that are usually set up when the Smart Controller is installed or adjusted are referred to as Program
Parameters. To get to the Program Mode, press and hold the Mode button for at least five seconds. When the
controller has entered the Program Mode, the display will flash between P1 and the current value of the
program parameter. All the program parameters have a program number assigned to them. When in the
Program Mode, the current displayed parameter can be changed by pressing the Up ( ) or Down ( ) arrows.
