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.
