4. INSTALLATION

The HIT-2A has an input conditioning circuit, which accepts signals
from most frequency or pulse producing flowmeters.
The input will interface directly to:
Turbine Flowmeters
Reed Switches
Logic Signals
Open Collector Outputs
The input is protected for over voltage up to 50 volts.
The flowmeter input (terminals 1 & 2) must be configured for the
selected signal type by appropriately setting the input selection jumpers
found on the HIT-2A signal input board (see following for jumper
positions).
