(1) FIELD CONVERSION OF A GSTC/SETC SERIES HUMIDIFIER WITH NORTEC LINKS 2 BACNET, LONWORKS AND N2 MODULES: A. WIRING THE NORTEC LINKS 2 MODULE (1) Most of the wiring connections for the new Nortec LINKS 2 module will have already been finished at the factory, however, there are a few connections that will need to be made to connect the unit the GS/SE series humidifier. Refer the LINKs 2 wiring diagram included in the package for details.
B. MOUNTING THE LINKS 2 ASSEMBLY (1) Refer to Figure 2 for the mounting location of the Nortec LINKS 2 Bracket on the GS or SE unit. If pilot holes for the mounting screws are not already present on the humidifier frame follow steps 2 and 3. If pilot holes are present then disregard steps 2 and 3. (2) Using the bracket assembly as a template, mark locations of pilot holes on the GS/SE humidifier frame. (3) Using 1/8” drill bit, drill pilot holes for the bracket mounting screws.
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.
