Maintenance
Warning!
The safety functions and the mechanics shall be tested regularly. Check
correct operation of all circuits and the lock function at least once a year.
Caution!
The electromagnet shall be regularly cleaned to maintain its full holding
power. Dirt or dust on the anchor plate or Magne can cause low or no holding power.
Warning!
In case of breakdown or damage to the product, remove and replace it
with a new unit. Contact the nearest ABB Jokab Safety Service Office or reseller. Do
not try to repair the product yourself.
Never
bypass the safety circuit.
Warning!
ABB Jokab Safety will not accept responsibility for failure of the switch
functions if the installation and maintenance requirements are not implemented.

Power source
The Limited Voltage / Current source must comply with one
of the following:
a) An isolating device such that the maximum open circuit
voltage potential available to the circuit is not more than 24
VDC and the current is limited to a value not exceeding 8
amperes measured after 1 minute of operation.
b) A suitable isolating source in conjunction with a fuse in
accordance with UL248. The fuse shall be rated max. 3 A
and be installed in the 24 VDC power supply to the device
in order to limit the available current.
