Check terminals 1 and 2 for proper voltage (12 – 24 VAC / VDC
± 10%).
Ensure field of detection is clear during set-up and all lenses are installed on
sensor. If detection is encountered upon initial set-up, the Bodyguard will
continuously flash green at ±2 Hz.
Permanent stationary objects are extremely close to the sensor. Ensure
that the detection field clear and the sensor is mounted properly (using the
Bodyguard mounting block if necessary).
Ensure no high-intensity lighting is in the immediate area of the sensor.
Change to a different frequency.
Verify that the data matches type LO21 or EDPS.
Verify no changes in detection field made since set-up. If permanent
changes have occurred, launch a new set-up and re-test door (CAUTION:
THERE MAY BE NO SAFETY ON THE DOOR WHEN THIS TEST IS
PERFORMED).
Remove output wires from the sensor. For controls using N.C. circuits, twist
together the relay wires.
Activate the door control. If the door opens, the fault exists with sensor
or related wiring. If door does not open, the fault may exist with the door
control or its related wiring.
Disconnect green and blue wires from LO21 to the door control safety
and common terminals. If door opens when triggered, fault lies within
the lockout safety beam set, or possibly with the LO21. Refer to the LO21
troubleshooting procedures in the respective manual.
Ensure proper relay output setting.
1) Allow door to open in automatic mode. Unlock sensor and launch a set-
up by pressing the Set-Up key, followed by the number 2. If the sensor LED
returns to red and does not begin flashing green, improper data exists.
2) If unsuccessful, allow the door to close. Unlock sensor and launch a set-
up by pressing the Set-Up key, followed by the number 2. If the sensor LED
flashes green, the lockout module needs replaced.
Refer to respective lockout User's Guide for troubleshooting.
Verify that the negative wire from the lockout (white) is connected to
terminal 6, and the red/white wire from the lockout is connected at terminal
7.
HELPFUL HINT: If faulty data is suspected, simply power the door to the
open position (by activation OR with the use of a "hold open" switch).
While the door is open, unlock the sensor and press the Set-Up key,
followed by the number 2. If the sensor LED returns to red and does not
begin flashing green, improper data exists. Refer to respective lockout
User's Guide for troubleshooting.
Replace batteries.
Move closer to sensor during programming.
Verify data matches type LO21 or EDPS.
Attempt manual programming procedure (page 7).
HELPFUL HINT: Use Spotfinder to test RC output.
Verify monitoring is active in door control (active low).
Replace sensor.
Verify DIP switch poisiton (must be switched to the left).
Verify door control is capable of monitoring and sensor monitoring wires are
properly connected to control.
Verify that there are no breaks anywhere in the wire harness.
Move monitoring DIP switch to the right (OFF) OR apply 12 – 30 VDC to the
purple and purple/yellow wires (observe polarity).
