Software Configuration
The Nortec GS humidifier is shipped fully configured from the factory to suit your site-specific require
-
ments, but this can be modified as needed. This section provides the necessary instructions to recon
-
figure the control software.
4.3.1
Configuring the Control Software
Perform the basic setup of the control software as follows, if necessary:
1. Make sure that all control wiring and jumpers are installed as described in "External Connections"
in the Installation Manual.
2. Set up the following parameters:
•
– select the type of control signals to the humidifier ("Analog", "Modbus", "BACnet/IP", etc.,).
Select "Analog" if a sensor/transducer signal or a demand signal from an external P/PI (pro
-
portional)/(proportional-integral) controller is wired directly to the humidifier. Otherwise, select
an applicable digital communication protocol from the list. If your humidifier has the optional
Lonworks or BACnet (BTL) module installed, select "Modbus".
•
– select the number of control channels.
Select "Dual" if controlling the humidifier with a high limit and a control signal; otherwise set to
"Single".
•
– select the general control mode for the incoming control and high limit signal
("Demand", "RH P", "RH PI", or "On/Off").
Select "Demand" if the control signal is a demand signal from an external controller. Select "RH
P" or "RH PI", as appropriate, if the control signal is from a sensor/transducer. Or select "On/Off"
if the control signal is from an external On/Off humidistat.
•
Signal Type
– select the signal type of the incoming control signal if
is set to "Demand",
"RH P" or "RH PI", and signal
is set to "Analog".
Select from "0-5V", "1-5V", "0-10V", "2-10V", "0-20V", "0-16V", "3.2-16V", "0-20mA", or "4-20mA",
as appropriate for the external control device connected to Channel 1.
This concludes the basic setup of the control software.
4.3.2
Configuring for Multi-Unit Operation
Set up the control software for multi-unit operation as described below. A maximum of four humidifiers
can be set up in a "Main-Extension" configuration using Condair's Linkup system to satisfy large hu
-
midification needs.
IMPORTANT!
This procedure should only be used to control multiple humidifiers that are using the
same control signal inputs from the same conditioned environment.
1. Make sure that all wiring and jumpers are installed, as described in "Connecting Multiple Units Using
Linkup" in the Installation Manual.
2. Configure the main humidifier as described in
"Configuring the Control Software" on page 42
3.
to "Main" on the humidifier that will be designated as Main in the Linkup chain, and set up
the following parameters on it:
•
– select the total number of humidifiers in the Linkup chain. For example, if there is
one main unit and two extension units, then the total number of humidifier in the chain is 3.
•
– select the mode of operation of the humidifiers in the Linkup chain ("Series" or
"Parallel").
•
– enable or disable the function that manages the starting order to balance the
operating hours on each steam cylinder.
Note:
This setting is available only if
is set
to "Series".
