Tips

  • The relay contacts are connected serially to the elevator COP button contacts, make sure that the polarity going in to terminals are correct.
  • Most COP buttons may carry 24vdc, make sure that the polarity going in to terminals are correct to prevent back electromotive force.
  • The jumper setting required by most elevator suppliers on XP-SNET-E32R extension board is set to Dry Contact with NO type for standby.

.

Note

If the back EMF is not controlled or suppressed it will generate very large voltages that in turn can:

  • Causes arcing at contacts, reducing contact life.
  • Generate interference.
  • Damage electronics.

Common Issues:

Cabling termination not following the correct polarity may cause reduced relay contact life and generate additional interference.
