General information
The Merlin CS1 & CS2 Current Switch is to be used in conjunction with the Merlin range of kitchen
ventilation interlock systems and can be used as an alternative to air pressure differential switches.
AC Current Switch Device
The AC current switches activate a normally open (NO) contact closure via a solid state switch
whenever the monitored primary circuit current exceeds a pre-set level.
The live wire running between the fan controller and the fan loops through the current switch
device until the [ON] light has illuminated. The more times the wire is wrapped through the loop,
the more sensitive the current switch becomes.
The current monitors can be wired back to the Merlin range by way of low voltage cables.
