Troubleshooting for Sensing Circuit w/Milk Flow Simulator PN # 70019
# 70019 Cow Simulator
# 70140 Flow Cell
Sensor w/8’ (2.4m) Cable
Step One:
Insert Cow Simulator into inflow end of Flow Cell.
Step Two:
Align pins in Flow Cell with matching holes in the Cow Simulator. The Cow Simulator will
fit as shown below.
Step Three:
Switch the Control into the milking mode.
Step Four:
If the milk yield circuitry is operating correctly the will count milk. Flow rates will vary
since each milk flow simulator is not exactly the same however as long as the counts and registers
milk yield the sensing circuit is working properly.
***
If, on the other hand, It does not count milk refer to the trouble shooting guide

Replacing Flow Cells
When replacing a flow cell normally using the scotch lock wire splicing connectors (PN#20205) to
splice the wires is an excellent choice. Be sure to protect the wire spice connectors after installation.
It is best to keep the spices covered in a box or PVC tubing away for direct water. Be sure the
scotch lock connectors are applied properly. (Wires fully inserted and completely tight).
