Maintenance Manual

25
- Phase Loss L3: Activates if the third phase of the normal power connection does not meet the qualification criteria.
- Lock Rotor Current: Activates when a lock rotor condition has been detected on the normal power. Note that the
motor will not be permitted to start on the normal power as long as this alarm has not been reset from the alarms
page.
- Fail to start: Activates if there is and under-current draw of two phases when the motor should be running. A 20
second factory set delay is used to give the motor enough time to start before signalling this alarm.
- Automatic Transfer Sw. Trouble**: After a factory programmed delay, activates upon detection of any of the
following transfer switch data: The alternate position and normal position limit switches are both activated OR none
of the alternate position or the normal position limit switches are activated OR the voltage reading on the line side of
the motor contactor does not match the reported input voltage .
- Loss of power: Activates when a complete loss of normal power is detected.
- Service Required: Activates when service is due for the controller. This occurs when the date set in the service
page has passed or if no service has ever been done.
- Undercurrent: Activates when current is under 30% of FLA and the motor has been running for 15 seconds.
- Overcurrent: Activates when current is above 150% of FLA.
- Undervoltage: Activates when normal power voltage is below 80% of nominal voltage.
- Overvoltage: Activates when normal power voltage is above 115% of nominal voltage.
- Phase Unbalanced: Activates when there is a difference of more than 10% of nominal voltage between the normal
power voltage readings.
- Weekly Test Cut-In Not Reached: Activates if the Cut-In is not reached during a manual or weekly test. At the end
of the 20s timer, if the Cut-In is not reached, the test may still be successful at starting the motor if the pressure has
dropped by at least 5 PSI.
- WT Check WT Solen: Activates if the pressure does not drop a minimum of 5 PSI during the manual run test or
the weekly test. Indicates a failure with the Test Solenoid Valve.
- PT Fault Detected: Occurs if the pressure reading is out of its normal range. Additionnally, if an optional dual
pressure sensor is installed, it will be activated if the two pressure transducers show different readings. Further
investigation is advised to determine what caused the different readings. Note that the controller will always choose
the lowest pressure reading to determine the actual system pressure. Also, if the voltage powering the transducer is
below 0.5V or over 4.5V the alarm will be activated.
- Alternate Power Phase Reversal**: Activates when the phase order on the alternate power does not match the
correct value of the controller. Each time a service is acknowledged on the ViZiTouch, the controller synchronises
the correct phase order to the one detected on the normal power.
- Alternate IS Tripped/Opened**: Activates when the AIS is either tripped or opened. This alarm condition rings the
buzzer and cannot be silenced.
- Alternate CB Tripped/Opened**: Activates when the ACB is either tripped or opened. This alarm condition rings
the buzzer and cannot be silenced.
- I/O Electric Communication Error: Activates if no communication between the ViZiTouch and the electric I/O card
could be established for 15 seconds. This alarm is critical and triggers the buzzer as well as deactivating the failsafe
Power Available output relay. If this alarm persists for more than 1 minute, the controller will reboot to try to fix the
problem.
- I/O Transfer Switch Communication Error**: Activates if no communication with the transfer switch I/O card could
