NOTE: The timers have a range of 0–99 seconds.
They will count down from the set value to
0 in one second intervals. The factory de-
fault setting for each timer is one second.
OPEN BACKUP TIMER
This is the backup timer for the opening of the door.
This timer will stop the door if it does not reach the
open limit switch within the set time. When the time
has been exceeded, the OP = 0 message will be
displayed and the LSO LED will blink until the system
has been reset.
To reset the system:
Determine the reason for the
door not reaching the limit switch and correct the
problem. Then reset the Digital Gateway by pressing
the Open Jog/Reset button or the Stop button.
This timer should be set for 1–2 seconds longer than
it takes the door to open. It will count down as the
door is opening. Setting and messages for this timer
will be displayed as "OP =" plus time.
CLOSE BACKUP TIMER
This is the backup timer for the closing of the door. It
functions the same as the open backup timer. When
the time has been exceeded, the CL = 0 message will
be displayed and the LSC LED will blink until the
system has been reset. This timer should be set for
1–2 seconds longer than it takes the door to close.
Setting and messages for this timer will be displayed
as "CL =" plus time.
ALTERNATIVE ACTION (A/A) CLOSE DELAY TIMER
This timer delays the closing of the door when it is
opened by an A/A activator or PB1 connection (termi-
nals 11 or 12). After the A/A or PB1 connection is
removed and the door has reached the open limit
switch, the timer will time out and close the door.
For no closing delay, set the timer to 0. Settings and
messages for this timer will be displayed as "ACL="
plus time.
The use of this timer is optional. It is turned on with
the A/A Close Delay Option button. The LED above
the button will be on when the timer is on. To operate
the door manually with the A/A or PB1 connection,
this timer should be OFF. (Figure 6.)
