(1)FIELD INSTALLATION OF A
A.STEP 1 - INSTALLATION
(1)Mount the LINKS 2 remote package in a convenient location. Note that the remote package does not need to be mounted in close proximity to the humidifier.
(2)Connect power to the 24VAC and GND terminals of the LINKS 2 terminal strip. This may be done in two ways:
(a)A 120VAC to 24VAC
(b)Connect power from the humidifier terminal strip (see wiring diagram for details).
NOTE on 2(b)
Power to LINKS 2 module will be lost when the humidifier is switched off.
(3)Connect the slave humidifiers (if applicable) to the Nortec Links Module. A twisted pair cable should be used so that the Net + terminal on the Links module should connect to the first pin
A.STEP 2 – CONFIGURING THE HUMIDIFIERS
NOTE
If the LINKS 2 remote package was shipped with the humidifiers, this step will have already been performed by the factory.
(1)Since Nortec LINKS 2 can connect to a maximum of 8 units, it will be necessary to set the unit address for each humidifier. The lead unit can be determined by the presence of the LINKS 2 module. The slave humidifiers can be given a unit address according to the number the unit will have on the networked chain.
(2)To set the network address access the User Parameter level in the humidifier software menu. Scroll down to Modbus Settings and press enter.
(3)In order to change the current modbus address, press the up and down arrows on the keypad at the same time. When prompted, enter the code 0335.
(4)Once the password is set select the modbus address heading and press enter. Use the up and down arrows to change the address setting.
(5)Determine the desired humidifier ordering on the network. To change the network instance follow step 3 and enter the parameter value of 2 for unit 2, 3 for unit 3 and soon.
