Remote Fault Option Wiring
The NHRS remote fault option (P/N 1508069) includes four relays that can provide remote
status indication. The relays are mounted to a remote fault board which is located as shown in
Figure 26. The PCB with the relays includes markings which indicate the function of each
terminal on the board. The relays indicate the following status:
1
Unit On
– The normally open relay is closed when the humidifier has power and the On/Off
switch is set to on.
2
Steam
– The normally open relay is closed when the control board detects that the cylinder
is drawing current and steam is being produced.
3
Service
– The relay can be wired to open (NC) or close (NO) when a warning is displayed on
the humidifier display and the yellow service LED is illuminated.
4
Error
– The relay can be wired to open (NC) or close (NO) when a fault is detected by the
humidifier controls.
