There are four jumper links positions: J9, J10, J11 and J12, associated with configuring the turbine
meter counter inputs for either millivolt signals (direct to sensor) or high level signals from turbine
meters with external amplifiers, dry contacts or open collector outputs.
Jumper positions J9 and J11 enable the SCADAPack’s pre-amplifier on turbine counter input 1.
Jumpers J10 and J12 enable the SCADAPack’s pre-amplifier on turbine counter input 2.

Directly Connecting to Low Voltage Turbine Meters
When connecting a low voltage (millivolt) turbine meter directly to counter input 1, enable the
SCADAPack’s internal pre-amplifier on this input as follows:
1.
Install jumper J11 on the ‘Int Amplifier’ position.
2.
Install jumper J9 on the ‘See J11’ position, as shown below.
