7.3 Safety interlock
Risk of electrical shock!
Hazardous electrical voltage!
When standard wiring was made, terminal 1
shows 230 VAC after commisioning.
Across terminal 1 and 2 the so-called safety
interlock is wired. This wiring allows for inte-
gration of safety devices. In case of an open
safety interlock the steam humidifier does not
operate.
Factory setting leaves the safety interlock
open!
Install contact interlocks, e.g. a max.
hygrostat, vane relays, pressure controllers,
air interlock devices etc. in series across ter-
minal 1 and 2.
Contacts across terminals 1 and 2 must
be potential free and properly rated!
Rating must comply with the control voltage
in use.
Best practice implies the integration of a max.
hygrostat in the safety interlock wiring to pro-
tect against over-humidification due to a r.h.
sensor malfunction.
