Maintenance; Led Indication; Technical Data - ABB Magne 3 Series Excerpts From The Original Instructions

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.

Description
Eva within sensing distance, safety
circuit closed
Eva within 2 mm of maximum distance
Eva within sensing distance, safety
circuit broken before this unit
Eva out of sensing distance, safety
circuit broken
No Eva programmed
Fail safe mode
Invalid input signal
Magne is not detecting the anchor plate
Magne is locked
Action
Check +24 VDC power supply.
Check anchor plate position.
Move Eva within sensing distance of
Adam. Remove metal.
Replace the unit. Contact
ABB Jokab Safety.
Replace Eva. If it still does not work, the
unit is defective and must be replaced.
Power cycle (i.e.turn off power, wait for
1 minute and turn it on again).
1. Check output signal from the
previous unit in the signal chain.
2. Turn off power supply.
3. Move Eva within sensing distance.
4. Power supply.
Power cycle (i.e. turn off the power,
wait for 1 minute and turn it on again).
If fault recurs, check incoming signals.
Safety have a cross sectional area of 0.34 mm
not cause any power surge when locking is activated.
Connector

Intended usage Applications as NFPA 79
Connecting cables Cables to comply with CYJV/7, with a conductor area of min
0.2 mm
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.
