Brake Adjustment

The brake is adjusted at
the factory and may need
periodic adjustment for
wear. When adjustment
becomes necessary see
Figure 14 at right for the
adjustment procedure.
SETTING THE SWITCH SELECTABLE OPERATING MODES
Changing the Switch Selectable Operation Modes
The following modes are selected by setting the on-board
dip switches, Figure 15 at right shows where the switches
are located on the operator control board. For each
Operational Mode, the switches are set to either ON or
OFF according to the table below (the table is reproduced
on page 16 also). For all the modes, if a reversing device
is attached, it will function as noted. If a monitored
reversing device has been recognized and becomes
inactive then the mode will default to constant pressure
activation for close regardless of the dip switch setting.
The switches must be set to one of the six Operational
Mode combinations for the operator to function.

door.
Close Button: Constant activation, door will stop when button is
released.
Stop Button: Momentary activation; stops open, close or reverse

Mid-Stop: Activation stops an opening door; momentary contact
of open button at mid stop will restart door to full open position;
if door is moving open, constant pressure on open button will
bypass mid-stop.
