VI Start Up Procedure

Danger: Shocks, burns, or death may result from high voltage.

Caution: Only personnel who are familiar with the power distribution system and this manual should be allowed to perform this procedure.

1.Verify that the motor nameplate horsepower and voltage match the Controller nameplate.

2.Verify that the CIRCUIT BREAKER DISCONNECTING MEANS is open. Check with the electrician to see if the Controller is connected directly to the main transformer. If so, apply the Service Disconnect label above the CIRCUIT BREAKER handle operator.

3.Verify that the PLM is set to the line voltage.

4.Verify that the customer connections to the CIRCUIT BREAKER and contactor are properly tightened.

5.Carefully remove the foam packing from the PS (pressure switch) between the mercury switch and the bourdon tube. Remove the installation instructions above the tube. Replace plastic cover.

6.Adjust the PS set points on the right side of the switch to meet water system requirements. Set the upper pointer to the required STOP (HIGH) pressure setting. Set the lower pointer to the required START (LOW) pressure setting.

The scale on the PS is only for initial positioning of the pointers. During testing of the Controller, verify the PS settings by referring to the system pressure gage. Readjust settings as necessary to obtain desired STOP and START settings. Refer to the instructions packed in the PS and NFPA 20 for more information on adjusting the settings.

7.Verify that the minimum run timer TR1 is set for 10 minutes, per NFPA 20. The timer can be field set as required by local jurisdiction.

8.Close the cabinet door and close the CIRCUIT BREAKER DISCONNECTING MEANS. After a five second delay, verify that the POWER AVAILABLE light is on. If equipped with a Transfer Switch, verify that the green LED on the PRM (phase reversal monitor) is on after a five-second delay. If the LED’s are not on, open the CIRCUIT BREAKER and change any two leads (L1, L2, and L3) on the PLM. If equipped with a Transfer Switch, change the same two leads on the PRM.

Caution: Note that the pump should be primed and the water source available before running to avoid damage to the pump. To avoid flooding, ensure the sprinkler system is completely installed and ready to be pressurized.

9.Bump the motor by pressing the START button and then press the STOP button, to check for proper rotation. If not correct, open the CIRCUIT BREAKER and change any two leads on the load side of the M1 contactor.

10.Press the START push button. Verify that the motor starts properly and runs at full speed.
