STP-200/300/400 Series Instruction Manual
6.2 Restarting after Any Safety Function Operates
1) In case of a power failure:
Establish a sequence so that power can be supplied to the STP control unit
immediately after a power recovery.
2) In case the "FAILURE" lamp lights due to an overload of the inverter or the
“EMERGENCY OPERATION” lamp lights due to excessive vibration:
Confirm that the STP pump stops thoroughly (that the ROTATION meter
deflects to full-scale in the red), and perform the POWER OFF operation.
The "FAILURE" or the "EMERGENCY OPERATION" lamp goes out. Then,
restart the STP pump and check if it operates correctly.
◇ For probable causes and troubleshooting, see Section 15,
"Troubleshooting."
3) In other cases:
Confirm that the STP pump stops thoroughly (that the ROTATION meter
deflects to full-scale in the red), and remove the cause of the
abnormality/error. Then, restart the STP pump and check if it operates
correctly.
◇ For probable causes and troubleshooting, see Section 15,
"Troubleshooting."
