Safety 2 (selects how the plug-in safety loop
detector will affect the gate’s operation)
OP Opening: Gate stops when safety device is
triggered and closes when safety device is
cleared.
Closing: No effect
CL Opening: No effect
Closing: Gate re-opens when safety device is
triggered.
OC Opening: Gate stops when safety device is
triggered and closes when safety device is
cleared.
Closing: Gate stops when safety device is
triggered and opens when safety device is
cleared.
After you have made all your programming selections
and run the gate at least one full cycle at full speed, you
must toggle through each function again to lock them in
to the memory. This will also give you an opportunity to
double-check the setting of each function. It is best to
leave the display showing the St (Status) function so that
the status of the gate will always be displayed.
Note: If you find the display showing two red
dots, this is a power saving mode. The display
will return if you push the + or - buttons.
Test the System
Once you have connected main power, connected the
accessory devices, and programmed the 885, you can test
the gate system.
WARNING! If you have not performed a
preliminary limit adjustment (discussed on page
7), do so before testing the operator.
With the gate in the closed position, turn on the main
power and check the status of the LED indicators. See
LED Indicators on page 13. Correct any problems with
your input devices if necessary. Once the LEDs are
illuminated properly, make sure that the gate path is
clear, and give the 885 an activation signal. The gate
should run open slowly as it looks for the open limit. If
you are in the automatic mode, the gate should time out
and close after the programmed pause time. If you are in
any other mode, give the operator a close signal. The
gate should run closed slowly as it looks for the closed
limit.
The initial cycle is a learning mode in which the gate will
run slow as it searches for the limit switches. Once it is
complete, the operator will run at full speed.
Continue to cycle the gate and test all input devices. Be
sure that all safety devices are functioning properly.
Entrapment Protection
The 885 Operator features an entrapment protection
system. It incorporates an optical encoder, which
monitors the gate’s movement, along with an adjustable
force output and an audible alarm to warn you when the
gate encounters something or someone.
WARNING! The entrapment protection system
will not function properly if the force setting
(see
Programming on page 13) is not set
properly. It must be set strong enough to move
the gate consistently, but be able to be stopped
if it encounters a force of 40 lbs. or more.
WARNING! The entrapment protection
system must be adjusted to function properly to
comply with UL325.
Encoder
The encoder is a device that monitors that movement of
the gate. It determines when the gate will slow down
before triggering a limit and when the gate has
encountered an obstruction. If it senses that the gate has
stopped moving without a limit being triggered, the gate
will invert movement and run slowly the other way.
Audible Alarm
The 885 features an audible alarm that will sound if the
gate encounters two sequential obstructions in the same
cycle. For example: The gate is running closed and
encounters an obstruction. The encoder senses this and
immediately re-opens the gate. If the gate encounters
another obstruction before reaching the open limit, the
gate will stop and the alarm will sound. The main power
must be reset before the operator will be ready for
another signal.
Final Limit Adjustment
Once the system has been tested thoroughly and
everything is functioning properly, you will need to fine-
tune the limit adjustments. Following the same steps as
you did during the preliminary limit adjustment, fine-
tune the position of the limit adjusters. See Figure 3. If
the gate stops too soon, back the limit adjuster off. If it
goes too far, turn it toward the limit switch. Make small
adjustments and cycle the gate after each adjustment to
check the result.
