2.4 Connection

2N® LiftIP Connection

2N® LiftIP is connected to the LAN via a Cat 5e or higher UTP/STP cable terminated with an RJ-45 LAN connector. 2N® LiftIP can be fed via PoE or an external DC 10–30 V 0.5 A power supply. Once connected, 2N® LiftIP gets the IP address from the DHCP server. To know the IP address, enter the system voice menu and press and hold the upper MENU button for a long time (see the cover print).

Or, use the 2N® LiftIP Service Tool application including the network scanner. Refer to Subs. 5.3 Service Tool – Use for details.

Having set the VoIP parameters (SIP server, username, password, etc.) via the Service Tool, you can call 2N® LiftIP  and set additional parameters remotely. 2N® LiftIP receives DTMF via RFC-2833 by default, or you can set the detector to in-band (parameter 1108, via the Service Tool only).

Caution

  • Fit the Ethernet cable to the motherboard using a cable tie to prevent mechanical stress of the connector.

 ALARM Connection – Contact Control

Accident Risk

  • The button must be safe: make sure that the button contacts are not connected to any other circuits. If these conditions cannot be met, use voltage control.

  • Connect the button contacts to the ALARM terminal. ALARM is set to normally open (N/O) by default (all jumpers on).
  • The button contact can be both N/O and N/C. Slide the right jumper out for N/C.

  • Use jumpers for configuration. The jumper link is below the ALARM terminal.

ALARM Connection – Voltage Control

Tip

  • DC voltage ranging from 5 to 48 V can be used. Make sure that the power supply is backed up against power outage.
  • Voltage is connected/disconnected for activation/deactivation. ALARM is set to N/O by default.
  • Slide all the jumpers off the configuration jumper link to control ALARM by voltage connection.

  • Keep only the right jumper on to control ALARM by voltage disconnection.
  • Use jumpers for configuration. The jumper link is below the ALARM terminal.

Warning

  • Keep polarity (see the cover print).

Indicator Connection

Basic connection

You can use any indicators (illuminated pictograms, e.g.) for basic connection. An external power supply provides a sufficient indicator brightness level. As 2N® LiftIP contains only switches, connect a circuit for current limitation if necessary, even if LEDs are used.

Requirements

  • 12–24 V supply (backed up if the indicators should work at power outage).
  • 200 mA permanent current (even with bulbs).
  • Make sure that both the indicators are connected!

Warning

  • Keep the power supply polarity!

Use of LEDs mounted on 2N® LiftIP electronics

Do not connect anything in this case. Light guides are used for this purpose to bring light to the two panel holes (refer to Subs. 2.3 2N® LiftIP Electronics Panel Mounting). Light guides are not included in the standard accessories.

 

Cable connected LEDs

Cable connected LEDs are used where illuminated pictograms are unavailable. They are not included in the standard accessories, but supplied separately or as part of customer deliveries. These LEDs are 5 mm in diameter and feature a very high luminosity.

Requirements

  • Keep the LED polarity (see the cover print).
  • Keep the colours: request confirmation – yellow, connection confirmation – green.

Note

  • The printed circuit LED is off in this type of connection.

CANCEL Connection (Door Contact, Optional)

Caution

  • Make sure that the door switch or door opening signal indicates that the door is open only if both the internal and external lift doors are open and the people can leave the cabin.

Note

  • Using the CANCEL input, program parameter 914 to a time value longer than the maximum lift travel time (i.e. the closed door time). If parameter 914 is set to 0, the CANCEL connection is meaningless and thus needless.

 

Switch control

  • Connect the switch to the CANCEL terminal.
  • 2N® LiftIP  is set to N/O contact control by default. All the jumpers are on the jumper link.
  • CANCEL can be set as N/C too. Slide out the right jumper for N/C.

 

 

Voltage control

DC voltage ranging from 5 to 48 V can be used.

  • Slide all the jumpers off the configuration jumper link to control CANCEL by voltage connection.
  • Keep only the right jumper on to control CANCEL by voltage disconnection.  

Caution

  • If voltage presence signals a closed door, make sure that the power supply is backed up against power outage.

Warning

  • Keep polarity (see the cover print).

Induction Loop Connection

Abide by the applicable regulations that may require induction loop installation as a communicator installation requisite. Connect the induction loop to the LiftIP back connector. Polarity is arbitrary. The induction loop can be part of the delivery including a 4 m cable if agreed so. 

Requirements

  • We recommend you to install the induction loop behind a non-metallic, non-magnetic cover to avoid deterioration of the induction loop field radiation.
  • Make sure that the induction loop is marked with an appropriate symbol (ear) and its position complies with the applicable standards.
