4. Observe direction of motor rotation.
5. If rotation is incorrect, con
fi
rm that the isolating switch/circuit breaker is in the OFF position,
open enclosure door and reverse any two of the corresponding motor leads (T1, T2, T3, T6/T12,
T4/T10, T5/T11) on the load side of both contactors 1M and 2M. For example, reverse T1 and
T2 on contactor 1M and T6/T12 and T4/T10 on contactor 2M; or T1 and T3 on contactor 1M and
T6/T12 and T5/T11 on contactor 2M; or T2 and T3 on contactor 1M and T4/T10 and T5/T11 on
contactor 2M.
6. Retest for proper rotation following steps 1 through 4.
FTA1930 Controllers
1. Close enclosure door.
2. Momentarily close the isolating switch/circuit breaker handle, i.e. move up to the ON position
and then back to OFF.
3. The pump motor should rotate immediately if system pressure is low. If system pressure is not low,
press the manual START push-button and immediately press the manual STOP push-button.
4. Observe direction of motor rotation.
5. If rotation is incorrect, con
fi
rm that the isolating switch/circuit breaker is in the OFF position, open
enclosure door and reverse any two of the motor leads (T1, T2, T3) on the load side of contactor
1M. For example, T1 and T2, T1 and T3 or T2 and T3.
6. Retest for proper rotation following steps 1 through 4
FTA900, 975 POWER TRANSFER SWITCH
1. Con
fi
rm motor rotation from the normal power source for the controller as outlined above.
2. Open both the controller isolating disconnect switch/circuit breaker and the transfer switch iso-
lating disconnect switch by moving the operating handles to the OFF position.
3. Refer to the Automatic Transfer Switch Operator’s Manual. Manually transfer the switch to the
emergency power source.
4. Start the generator set at the generator control panel.
5. With the generator running at stable voltage and frequency momentarily close the power transfer
switch isolating disconnect switch. The pump motor should rotate immediately if system pres-
sure is low. If system pressure is not low, press the manual START push-button and immediately
press the manual STOP push-button.
6. Observe motor rotation. Con
fi
rm that the isolating switch is in the OFF position. Shutdown
generator set.
7. If rotation is incorrect, reverse any two of the line leads at the power transfer switch isolating
disconnect switch (L1, L2, L3). For example, L1 and L2, or L2 and L3, or L1 and L3.
8. Retest for proper rotation following steps 1 through 6.
FTA950, 976 POWER TRANSFER SWITCH
1. Con
fi
rm motor rotation from the normal power source for the controller as outlined above.
2. Open both the controller and transfer switch isolating disconnect/circuit breakers by moving the
operating handles to the OFF position.
3. Refer to the Automatic Transfer Switch Operator’s Manual. Manually transfer the switch to the
emergency power source.
4. Momentarily close the power transfer switch isolating disconnect switch/circuit breaker.
The pump motor should rotate immediately if system pressure is low. If system pressure is not low,
press the manual START push-button and immediately press the manual STOP push-button.
5. Observe motor rotation.
6. If rotation is incorrect, con
fi
rm that the isolating disconnect switch/circuit breakers are in
the OFF position. Request the utility company to disconnect the second utility incoming
power at the source, then reverse any two of the line leads at the power transfer switch isolating
disconnect switch (L1, L2, L3). For example, L1 and L2, L1 and L3, or L2 and L3.
7. Retest for proper rotation following steps 1 through 5 above.
