devices (the devices are ignored when the door is closed). Setting AF to 3 allows this connection to
be used for a safety beam input. Other values of AF are reserved and disable the CN7 input when
selected.
ct Cycle Test. This cycles the door at regular intervals for testing. Default is off.
PG Push And Go. This automatically completes a cycle if someone begins pushing the door open
manually. Default is off (no push and go). Also see the d2 parameter.
Cr Close recycle. This recycles the door open if an obstruction is encountered prior to the door
entering latch check. Default is on.
SL SLower open speeds. This reduces all open speed settings by approximately 50%, allowing the
use of very slow open speeds if desired. Remaining speeds (open check, hold open, etc.) are not
affected by
SL . Default is off (use normal open speeds).
LL Lock present. When the LL parameter is on, the control will trigger the lock relay prior to
opening. It will also attempt to unjam the door, if requested (see the UJ and UP parameters), and
will wait through the unlock delay (see the UL parameter) before opening the door. Default is off (no
lock).
HS Hold Strike. If the HS parameter is left off, the lock will be released approximately 1 second after
the door begins opening. This is normally the preferred setting, as it prevents burn out or buzzing of
inexpensive mortise type strikes. If
HS is turned on, the lock will be held in the released condition for
the total duration of the open cycle, the close cycle, and the latch check delay (see the LC
parameter). Default is off (do not hold strike through open cycle).
U1-3 User Parameters 1-3. These parameters adjust from 0-99 and are not used in any way by the
control itself. They may be set to any data the installer wishes to save (month/year of installation,
date of last service, technician code, etc.).
SPECIAL NOTES ON SYNCHRONIZED PAIRS
A six-conductor synchronization harness is supplied with paired operators. It is strongly suggested
that this harness be left unplugged until each door of the pair is set up properly and operating
normally as an independent unit. The harness may then be plugged into
SYNC connector CN5 on
each control to synchronize the two doors.
Connections for actuating and safety devices as well as the
on/off/hold switch may be made to
either control. It is not necessary to connect them to both.
Due to the method used for synchronization, it is not possible to have different values for the
standard delay (
d1 ) and the close recycle delay ( d3 ). Delays d1 and d3 should be set to the same
value in each operator, and must also be set identically on both operators. The push-n-go delay
(
d2 ) may be different from d1 / d3 , but should also be set identically on both operators. This
restriction does not apply to single operators.
