8 Troubleshooting
PROBLEM PROBABLE CAUSE CORRECTIVE ACTION
DP-Hub is not
showing any display
No input power
Check input power as it must be 12 to 24 VAC/VDC: +/- 10%, do not
power from the door control
Faulty DP-Hub Replace DP-Hub
Door will not open or
close
Door control issue Remove the DP-Hub from the door control by unplugging the Door
Control Harness(es). Attempt to open the door via the door control. If
door does NOT open, troubleshoot door control
No inputs or outputs connected Connect (as a minimum) the ON/OFF/HOLD Switch in the ON position,
the BodyGuard, the EDPS(s), an activation device and door control
BodyGuard data and/or relay conguration and/or
pattern width is incorrect
Verify BodyGuard relay conguration, BodyGuard data type matches
DP-Hub and pattern width is set correctly
DP-Hub function FA set to 01 when no AUX is
used
Check function FA at the hub. If no AUX device is used, value should be
set to 00
Safety Beam input Fb is set incorrectly
Check function Fb at the hub. If no SBK-30 beams are plugged into the
hub, value should be set to 00
SBK-30 Beams misaligned Align SBK-30 Beams
SBK-30 Beams faulty Replace SBK-30 Beams
Door Mounted Sensor wiring is incorrect Check wiring of Door Mounted Sensors (Section 5-6)
Door keeps recycling
open (ghosting).
Activation sensor ‘seeing’ the door movement. Adjust motion sensor or door mounted sensor at non-safety side.
BodyGuard ashing
orange
Bodyguard data is incorrect Check and change F1 at BodyGuard if needed
Check and change FL at DP-Hub if needed
Check wiring of BodyGuard (Section 5-4)
Error codes E1 & E3 EDPS is not connected to DP-Hub Check wiring of EDPS (Section 5-7)
EDPS is congured for 2 doors but is installed on
a 1 door system
Check function Fd at the hub. If it only a 1 door system, value should be
set to 01
Faulty EDPS Replace EDPS
Faulty DP-Hub Replace DP-Hub
Error codes E2 & E4 EDPS is not connected correctly to DP-Hub Check wiring of EDPS (Section 5-7)
Faulty EDPS Replace EDPS
Faulty DP-Hub Replace DP-Hub
If the DP-Hub is powered on and acting erratically, the best solution is to rst use the ‘Operating Parameters’ in conjunction with the
‘Programming Parameters” as described in Section 6 - Programming the DP-Hub for troubleshooting. The information obtained can also be
used with the six LEDs on the DP-Hub. The description of the LEDs is shown below. Once the problem is determined the
corrective actions can be taken as specied by the second table. Finally if you cannot solve the problem on your own, you can contact BEA
Technical Support whose contact information is provided in Section 9.
LED DESCRIPTION
Green DP-Hub activation relay is active
Yellow DP-Hub stall relay is active
Red DP-Hub safety relay is active
Orange DP-Hub home switch is active (contact is closed)
Blue DP-Hub is in Learn mode
White EDPS baseline is being tracked
NOTE: If the display goes blank but you have HOME, LEARN and TRACKING, the DP-Hub is relearning the sensor baseline for approximately one
second - this is normal.
NOTE: When troubleshooting with error codes, the lower error code number is a higher priority error. Fixing the lowest error code number rst may
resolve subsequent errors.
