2.  Use the chart (at right) for a quick-reference for 

time  delay  settings  (switches  1  through  5). 
Factory setting is 7 seconds. 

 

 

Example

The normal closing cycle of an automatic door lasts 
about 7 seconds.  In order to get the proper closing 
lock  out  time  delay  needed  for  the  closing  cycle  of 
the  door,  the  dipswitches  need  to  be  set  according 
to  the  chart  on  page  3  for  7  seconds.    To  get  the 
proper  lock  out  time  delay  dip  switches  1,  2,  &  3 
must  be  in  the  ON  position  and  Dip  Switch  4  must 
be in the OFF position. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
3.  DIPSWITCH #6: Corresponds to the type of motor voltage logic on the RED and BLACK wires.  Dipswitch 6 should be 

on for all applications that have the red and black wires going to a parallel motor connection. Dipswitch 6 should be OFF 
for applications where voltage is present on the red and black wires at the closed door position, and where 0 volts is 
present at the door open position. 

4.  DIPSWITCH  7  OFF  &  8  ON:

 

Provides  a  CLOSED  circuit  between  the  GREEN  (COMMON)  and  YELLOW  (SAFETY) 

during BODYGUARD detection and an OPEN circuit at all other times. 

5.  DIPSWITCH 7 ON & 8 OFF: Provides a OPEN circuit between the GREEN (COMMON) and YELLOW (SAFETY) during 

BODYGUARD detection and a CLOSED circuit at all other times. (Example:  Besam PowerSwing).
