MAIN CIRCUIT BOARD
TERMINAL
FUNCTION
DESCRIPTION
COM
Common
Input wiring “common” connection
O
Open & hold
On momentary signal it will cause an opening, or a stop and reverse if closing. Door will
timeout and close if dip switch #2 is “OFF.” If activated and maintained, door will stay
open.
C
Close input
N/A
SB
Single button input
Duplicates radio input. The following is the same for radio input- a signal will always
cause an opening except at the fully open position.
L/I
Lock/inhibit
When activated, the door will emergency stop and remain stopped until signal is
removed. If door is at rest, either open or closed, it will not accept a signal as long as SL
is activated. If L/I is activated while opening, door will stop. If the close timer (Dip
switch #2) is “OFF,” and L/I is activated during a closing cycle, the door will stop and
await another signal. This will meet the conditions of a safety mat condition.
TH
Timer hold open
If maintained, it will prevent automatic close. If there is a momentary contact, it will
reset the close time and the timer will begin timing when contact is released. This
could be used with a safety mat applications where the only concern is on the closing
cycle as it does not prevent an opening.
MOCT (Dip Switch
#1)
Manually open close
timer
When switch is “ON” and door is opened manually to full open, door will time out and
manually close. When switch is “OFF” and the door is opened to full open, it will stay
open until a new signal is received.
CTOFF (Dip Switch
#2)
Close timer off
When switch is set to “ON” it will inhibit the close timer and the door will remain open
until a signal button, radio or close input is received.
CLOSE ADJ
Adjust motor
activation time when
closing door
Turn clockwise to increase time that the motor is activated when closing the door.
Only small fractions of rotation are required to adjust the time.
AUTO CLOSE
Adjust dwell time of
door in open position
Turn clockwise to increase time that the door remains open. Turn counterclockwise to
decrease the time the door remains open. Only small fractions of rotation are required
to adjust the time.
POWER
INDICATOR LED
Indicates power
attached
LED is on when power is attached to unit. LED is off when no power is going to the
unit.
POSITION
INDICATOR LED
Indicates location of
door
LED remains on until the magnetic switch is activated.
