Maintenance
Warning!
The safety functions and the mechanics shall be tested regularly, at least once every year to confirm that all the
safety functions are working properly (EN 62061:2005).
In case of breakdown or damage to the product, contact the nearest ABB Jokab Safety Service Office or reseller.
Do not try to repair the product yourself since it may accidentally cause permanent damage to the product,
impairing the safety of the device which in turn could lead to serious injury to personnel.
Testing of the safety functions
Make sure the safety unit is working properly by following these steps:
Interrupt protection by moving Eva away from Adam. The LED will light red when Eva is out of position
relative Adam.
Interrupt the dynamic safety circuit before this unit. The LED will flash between green and red.
Move Eva to position next to Adam. The LED will light green if the safety circuit(s) before this unit is not
interrupted.
An additional function test can be made by slowly moving Eva away from Adam. The LED will flash fast between
green and red when Eva is 2 mm from max sensing distance to Adam.
Troubleshooting
LED indication
Expected causes of faults
Checking and measures to take
Lights red
Eva away
Move Eva closer to Adam
Metal (iron) between Eden
Remove the metal
24 VDC input to pin-2 (no dynamic signal)
Check if there is 24 VDC to input (pin-2). If Yes, check
cable or unit before and fix it.
No lights
Loss of power supply
Check 24 VDC / 0 VDC power supply
Lights green (but no dynamic output
detected)
Defected dynamic signal input to unit
(asymmetric pulses)
Check the dynamic input or the unit before
Lights green/red (flashing)
No dynamic input (Eva in position with
Adam), or info-output (pin-5) connected to
0 VDC
Check the unit before (make it active). Check the info-
output, fix it.
Weak lights or red and green lights at
the same time
The unit is defect
