INSTALLATION
The K-Factor scaler was designed with terminal connections with removable plugs for easy connection and removal from the
system after installation See
meter input and the pulse output to a totalizing device
Voltage Input
8.5...30V DC
Pulse Output
Enclosure Mounting (necessary for CSA certification)
If the circuit board assembly is supplied without an enclosure, it must be mounted within a certified Appleton one inch NPT
model GRL100-A or GRLB100-A conduit outlet box to maintain the CSA "Ordinary Locations" certification The label containing
the hookup information should be placed on the inside of the cover of the enclosure The label containing the CSA logo
should be placed on the bottom exterior of the enclosure
Power
The K-factor scaler requires 8 5...30V DC to operate The power connections are reverse polarity protected by a diode, but
must be connected properly for operation of the device Polarity is shown in
Turbine Meter
The turbine meter connections are non-polarized and located on a separate 2-position terminal Use shielded, twisted pair
wire for this connection
