C.CONFIGURING THE HUMIDIFIERS

(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 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 so on.

(6)Place the appropriate Unit Identifier label on each humidifier. These labels should be placed on the unit where the electrical control punch-outs are located at the top of the humidifier.

(7)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 (bottom-most pin) of the TB3 connector. The Net – terminal on the module should be connected to the second pin of the TB3 connector. Refer to the unit’s wiring diagram for more information.
