LED Indicators
The 885 CAT has ten light emitting diodes that show you
what signals it is being given from the input devices
(open devices, safety devices, limit switches, etc.). The
following table shows the function of each LED.
DL2
Safety 2 Should be on unless the safety
circuit is triggered.
DL3 Open A Should be off unless an
activation signal is being sent.
DL4 Open B Should be off unless a partial
open signal (close signal in B or
C mode) is being sent.
DL5*
Open Limit Should be on unless the gate is
open.
DL6 Encoder Comes on each time the optical
reader reads a tooth on the
encoder.
DL7* Close Limit Should be on unless the gate is
closed.
DL8
Stop Should be on unless a stop signal
is being sent.
DL9 Safety 1 Should be on unless a safety
signal is being sent.
DL10 Solenoid
Lock Shows position of solenoid.
Depends on fail-safe or fail-
secure mounting.
DL11
+5 volts Should be on unless
microprocessor is receiving
inadequate voltage.
* If gate opens to the right DL5 is now the close led and
DL7 is now the open led.
Programming
Programming the 885 is accomplished by using the + , - ,
and F buttons located near the display on the control
panel. Each time the F button is pressed and held, the
next function is displayed. Each time the F button is
released, the value for that function is displayed and can
be modified with the + and - buttons. As you toggle the
F button through the programming functions, follow the
list below for a detailed description of each function.
Status (the operator status is displayed)
During operation, a number displays the current
status.
00 Closed
01 Opening
02
Stopped (no limit triggered)
03 Open
04 Pause
05
Fail- safe Test
06 Closing
07 Battery
On
Be sure to leave the Status function displayed after any
programming changes.
Pause time (selects the pause time before
automatic close from 0 seconds to 4 minutes)
“A” logic only.
Time is adjusted in one-second increments from 0 to 60
seconds. After 60 seconds is reached, time is adjusted in
one-minute increments up to 4 minutes.
Force (selects the motor torque at full speed)
Torque is adjusted from 0 (minimum) to 9
(maximum). The operator starts moving at the
maximum force for approximately 0.8 seconds. The
torque is then reduced to the programmed value.
Note: It is best to start with a force setting of 4
or 5, then adjust it appropriately for the
entrapment protection to work properly.
WARNING! To comply with UL325, the gate
must stop and reverse if it encounters a force of
40 lbs. or more. Be sure that force setting is
adjusted appropriately.
Time Out
(selects the maximum motor run
time from 0 to 100 seconds)
Time is adjusted in one-second increments
from 0 to 60 seconds. After 60 seconds is reached, time
is adjusted in 10-second increments up to 1 minute, 40
seconds.
Time out can be calculated by figuring the time it takes
for the gate to run open or close and adding 10%. Either
count the time (in seconds) it takes to open, or do the
math (based on a 1ft./sec speed) to figure the full travel
run time. Then use this formula to figure your time out
setting:
Full travel run time (sec.) x 1.1 = Time out
Logic (selects the operating logic)
There are four operating logics available on the
885 CAT:
A
Automatic mode- Gate opens with an activation
signal, stays open for the programmed pause
time, and closes automatically.
EP Semi-automatic mode- Gate opens with an
activation signal and remains there until another
activation signal is sent, at which time, it closes.
B Guard (manned) mode- Separate open and close
inputs. Use this logic with a 3-button station.
C Constant Pressure mode- Separate open and
close inputs. In this mode you must maintain
the signal throughout the travel or the gate will
stop.
