When all functions of the control and LO-21U have been confirmed, the lockout time delay will need to be set. Time
delay is set by using dipswitches 1 through 5. Perform the following steps:
q
Activate the door to the open position.
q
Allow the door to close and count how many seconds it takes for the overall door closing cycle
q
Configure the dip switches according to the chart on Page 3 for the lock out time that is required
q
Activate the door again to the open position
q
Stand outside of the Bodyguard detection pattern, and while the door is closing, observe the red LED on
the Bodyguard
q
The red LED on the Bodyguard should NOT illuminate during the closing cycle. If it does, it is probably
seeing the door at the very last degree or two of door closing, which would indicate that the lock out time
needs to be slightly increased.
q
Reconfigure the dipswitches to add 1 second of lock out time.
q
When the lock out time is correct. The red LED will not illuminate during the entire closing cycle of the
door.
q
The last test is to insure that the Bodyguard detects an object as soon as the door has stopped closing.
Simply allow the doors to begin closing, and step in behind the doors, into the Bodyguards field of
detection (be sure to NOT break the path of the lockout safety beams, if so equipped). The red LED shall
illuminate and remain on at the Bodyguard, and at the LO-21U, as soon as the door reaches the fully
closed position, provided that an object remains in the Bodyguard’s detection field.
With the door closed, the RED
LED does not come on upon
Bodyguard detection.
Note: Lockout Relay will not function correctly when power close function is enabled on the door control.
If after troubleshooting a problem, a satisfactory solution cannot be achieved, please call B.E.A., Inc.

PROBLEM PROBABLE CAUSE CORRECTIVE ACTION
With the door closed, the
GREEN LED comes on upon
Bodyguard detection.
With the door open, the
GREEN LED does not come
on upon Bodyguard
detection.
No Power applied to the Brown (+)
and Orange (-) wires.
Or
The Gray and Violet wires are not
properly connected to the
Bodyguard pins 3,4.
Dipswitch# 6 is in the wrong
position.
Reversed polarity or no motor
voltage on the RED and BLACK
wires.
Step 1
. Check for power 12-24 VAC / 15-24 VDC
on the Brown (+) and Orange (-) wires with a
meter. If voltage is there go to Step 2.
Step 2
. Jumper across Bodyguard connector pins
3,4.
•
RED LED does not come on, go to Step 3.
•
RED LED comes on, go to Step 4.
**Step 3
. Check continuity with a meter on the
Orange, Brown, Violet and Gray wires from the
back of the harness connector to the ends of the
wire. Correct any problem connections. If no
problem connections are found, replace LO21U.
Step 4.
Check Bodyguard Relay Mode function is
set to 1. If OK replace Bodyguard.
Step 1
. Check that Dipswitch# 6 is set correctly for
the application.
Step 2
. Remove harness from lockout and re-
install (this resets the LO21U).
Step 3
. Check motor voltage in door closed and
open position. Call Technical support.
Step 1
. Check Dipswitch# 6 is correct for
application.
**Step 2
. Check RED and BLACK wire
connections at the motor or source of door open
voltage. Correct any problem connections.
Step 3
. Reverse RED and BLACK LO21U wires at
the motor.
No LED display on the LO21U or
Bodyguard and door will not
open.
Dipswitch# 7,8 are in the wrong
position.
Step 1
. Check Dipswitches# 7,8 for proper
position for application.
Step 2
. Check control box connections for the
Yellow, Green and Blue wires.
** Remove power from sensors and door control
before performing these checks..
