. Two drawings above each other will show
typical wiring for turbine meter 1 and turbine meter 2. When dual pick ups from the same turbine are
connected, use the inputs for turbine 1 for pickup 1 and turbine 2 for the second pickup coil. When
connecting sine wave directly from the pickup coil make sure the distance from the pickup coil to the flow
computer is very short--less than 50 feet with shielded cable. In the event there is presence of noise, the
distance must be shortened. When connecting sine wave signal, the R11 jumper for meter 1 must be
installed and R3 jumper for meter 2 must be installed. (
JP3 and JP2 must be off when using sine wave
).
On the other hand, when using square wave, the square wave signal can be sinusoidal but has to be above 5
volts peak to peak with less than 0.4 volts offset in order for the flow computer to read it. R11 and R3 must
be off and JP3 on for meter 1; JP2 must be on for meter 2.
Note:
When connecting square wave input, the JP3 and JP2 connect the turbine return to the
flow computer power return. Therefore, signal polarity is very important. Reverse polarity
could result in some damage or power loss. When sine wave is used the signal polarity is
usually of no significance.
The turbine input is immediately under the power input on terminal P1. The third pin down from the top is
Turbine/PD "minus", and below it is Turbine plus. The second pulse input for Turbine/PD meter 2 or the
second pickup coil is below turbine one input on P1. The fifth pin down from the top is turbine 2 "minus"
signal and below it is Turbine/PD 2 plus signal.
