SETUP MODES
Setup Modes
Various operating characteristics can be modified via the setup
modes. The operator is moved to the close limit position and
the on-board dip switches (see Figure 14, page 15) are
TEMPORARILY set according to the table at right to enter a
Setup Mode. The on board OPEN and STOP buttons are used
to modify the characteristic. Once set, the values are stored in
non-volatile memory.
These values are set to factory defaults that should be
satisfactory for many applications. All values as described here
can be reset to the factory defaults as follows:
Remove 24 VAC power from the control board.
Press and hold the on-board stop button.
Re-apply 24 VAC while holding the on-board stop button.
After completing the procedure to modify the operating
characteristic the switches must be returned to the originally set
Operating Mode setting (see section previous).
Delay on Reverse Setup
To help prevent stress on the door components, this feature
allows for a delay time between the door stopping and reversing
when a command to reverse is received as the door is closing.
The factory default time is 0.75 seconds; the minimum time is
0.4 seconds; the maximum time is 2 seconds.
After moving the door to the close position and temporarily
setting the switches to the appropriate settings in the table,
pressing STOP will reset the time to the minimum setting.
Every time OPEN is pressed, 200 mS is added to the time (up to
the maximum).
Changing the dip-switch setting to any other setting will save
the new time. Return the dip switches to the originally set
Operating Mode setting (see section previous).
Close Limit Delay Setup
To provide for irregularities in the floor, this feature allows for
the door to continue to travel down after the Reverse Cutout
Limit is activated. The factory default time is 0.32 seconds; the
minimum time is 0.12 seconds; the maximum time is 0.66
seconds.
After moving the door to the close position and temporarily
setting the switches to the appropriate settings in the table,
pressing STOP will reset the time to the minimum setting.
Every time OPEN is pressed, 0.02 seconds are added to the time
(up to the maximum).
Changing the dip-switch setting to any other setting will save
the new time. Return the dip switches to the originally set
Operating Mode setting (see section previous).
