4.0OPERATION AND CALIBRATION OF THE Innova-Switch™FS4200 SWITCH FOR FLOW APPLICATIONS

4.1Pre-Operational Check

With the switch installed and process conditions at no-flow, the following procedure can be used to verify preliminary operation.

4.1.1Remove the instrument enclosure cover by turning counter clockwise (ccw) to expose the Innova-Switch™ Switch electronics.

4.1.2Turn on power at its source.

4.1.3Observe that either the red or green LED comes on.

4.1.4If neither lamp illuminates refer to the trouble shooting Section, 6.2.

4.2L.E.D. and Relay Status Logic (Fail-safe)

4.2.1The L.E.D.s (Red; Green) are an indication of the sensors status (ie. flow below the setpoint or flow above the set point) and are not affected by the position of the failsafe jumper J-2. The failsafe jumper J-2 changes the relay activation status allowing the user to select the failsafe power off condition most appropriate to the application. Refer to the tables below that show the logic conditions between the sensors, L.E.D. lights, relay coil and contacts for each position of the failsafe jumper J-2.

4.2.2Normal Operation (as set at factory)

The switch comes configured from the factory with the following operation with the J-2 jumper in the B(2-3) position. (Refer to Figure 8.0.)
