SET-UP
INSTRUCTIONS
The following instructions pertain to the setup procedures and the related indications that should be observed.
Immediately following each step, is a corrective action to perform if the step does not pass:
1.
Set the On-Off-Hold Open switch to the OFF position. If a switch is not available, unplug the activating device for
the door.
2.
To begin the set-up, apply power to the door system, to the LO-21U module, and to the Bodyguard. The
Bodyguard shall immediately begin flashing green to indicate a setup for the closed door position.
q
If the Bodyguard does not begin flashing green, check to insure it is receiving the correct power at inputs
1 & 2 at the 7-position terminal at the left side of the Bodyguard. Correct as necessary.
3.
Do not enter into the field of detection while the Bodyguard is setting up. After approximately 6 seconds, the green
LED will expire.
4.
Activate the door to the open position with the On-Off-Hold Open switch, or by jumpering the activate circuit. The
Bodyguard shall begin flashing green again while it is learning the “door open” set-up. Again, approx. 6 seconds of
un-interruption will allow a setup to complete. Once complete, the door should begin to close if activation is
removed. Place the On-Off-Hold Open switch to the On position. Normal operation thereafter.
q
If the Bodyguard does not begin flashing green when the door reaches full open, improper voltage may
exist on terminals 6 & 7 of the Bodyguard. Perform following:
Ø
Using a BEA remote control, and with the door in the open position, unlock the Bodyguard, then
press the Magic Wand key and then the number 2. This will force a setup for the open door position.
If the green LED does not begin flashing, unplug the 7-position connector at the Bodyguard.
Ø
Use a multi-meter (set to a DC voltage scale) to test the voltage at terminal 6 & 7. Place the positive
probe on terminal 7 and the negative probe on terminal 6. There should be approximately 12 Volts
DC. If voltage is 0 volts, check the white and red/white striped wires from the connector back to the
LO-21U for any breaks.
Ø
If wiring is good, check the voltage at the red and black wires on the LO-21U. Using a multi-meter,
place the positive probe on the red wire, and the negative probe on the black wire. Voltage should
not be less than 6 volts DC. If it is less, try increasing the stall voltage at the door control. If voltage
is 0 volts, make sure there is a good connection on the red and black wires. Also make sure the LO-
21U has the proper input voltage at the orange and brown wires.
5.
Once the Bodyguard is functioning correctly with regard to the open and closed door setup, walk testing may begin.
q
Do NOT proceed with walk-test until the Bodyguard is functioning correctly.
6.
The LO-21U has two LED’s to indicate what function it is performing. When the door is closed and someone steps
into the detection zone of the Bodyguard, the illumination of the
red LED
on the LO-21U will indicate that the LO-
21U is triggering the
safety circuit
. Therefore, the door will remain closed until the Bodyguard zone is clear. The
red LED will expire on the LO-21U and on the Bodyguard will shut off when the detection zone is clear. With the
door in the closed position, stand in the Bodyguard detection field and have someone activate the door (Eagle,
push plate, etc.). The door should not open. Clear the detection field of the Bodyguard, while keeping the door
activated. The door should open thereafter.
q
If the red led comes on at the Bodyguard, but not at the LO-21U, check to insure good wiring on the gray
and violet wires between the Bodyguard and the LO-21U.
q
If the red LED comes on at the Bodyguard and the LO-21U, but the door has no safety, check the green
and yellow wires between the LO-21U and the door control. If connections are good, jumper the common
and safety terminals at the door control, then activate the door to insure that the safety function is ok.
7.
Once the Bodyguard zone is clear and the door has been activated, it will open and remain open as long as there
is activation, or until door control and sensor hold-times have expired. If someone steps into the Bodyguard zone
when the door is open, the illumination of the
green LED
will indicate that the LO-21U is triggering the
activation
circuitry
of the door, thus holding the door open for as long as someone is in the Bodyguard detection pattern.
q
If the red led comes on at the Bodyguard, but not at the LO-21U, check to insure good wiring on the gray
and violet wires between the Bodyguard and the LO-21U.
q
If the red LED comes on at the Bodyguard and the green LED comes on at the LO-21U, but the door
does not hold open when the Bodyguard is in detection, check the blue and green wires between the LO-
21U and the door controls activation circuit.
q
Reverse the red and black wires at the LO-21U and try Step 7 again.
q
If all steps are Ok, LO-21U may be faulty. Replace as necessary.
