PHL
(19)
Phase Loss Warn
Input phase loss warning
Action and Reset
Action condition One of the phases outputs less than [PROT-23]
Action time [PROT-22]
Related parameters [PROT-21] = 0
Reset method Automatically
Reset condition After the drive stops
Recorded N/A
Possible Causes Corrective Action
• Phase loss of the input power
• Single phase power input on a three-
phase model
• The power voltage has changed
• Loose wiring terminal of input power
• Check if the input cable of 3-phase
power is broken
• The voltage of input power has changed
• Unbalance three-phase of the input
power
• Verify wiring of the main circuit.
• Use the model with voltage that matches the power.
• If the power of main circuit works well, check if the MC of the main circuit is broken. Cycle the power
after verifying the power is normal. If PHL still occurs, return to the factory for repair.
• Tighten the terminal screws with the torque listed in the user manual.
• Make sure the wiring is correct. Replace the broken part of the cable.
• Check setting for IPO Check Time [PROT-26] and IPO Ripple [PROT-27] .
• Check the status of three-phase power.
Warning Display Description
PID (11)
PID FBK Error
PID feedback loss (warning for analog feedback signal; works only when PID enables)
Action and Reset
Action condition When the analog input is lower than 4 mA (only detects analog input of 4–20 mA)
Action time N/A
Reset method Automatically
Reset condition Immediately reset
Recorded Yes
Possible Causes Corrective Action
• Loose or broken PID feedback wiring
• Feedback device malfunction
• Hardware error • Tighten the terminals again. Replace with a new cable.
• Replace with a new feedback device.
• If the PID error still occurs after checking all the wiring, return to the factory for repair.
Warning Display Description
PILA
(139)
Pipe Leak Alarm
Pipe leak detected in sleep mode where wake-up time is longer than [ADV2-48] , [ADV2-49] , [ADV2-50] , and [ADV2-51] .
Wake-up time is duration from pressure setpoint to wakeup level.
Action and Reset
Action condition Pressure drops for a duration longer than wake-up time between PID setpoint ( [ADV2-52] or and wakeup level)
Action time Longer than [ADV2-48] , [ADV2-49] , [ADV2-50] , and [ADV2-51]
Related parameters [ADV2-46] through [ADV2-51]
Reset method Fault/Warning is determined by [ADV2-46]
Reset condition Manually
Recorded Yes
Possible Causes Corrective Action
• Leak in pipe after pressure sensor
• System is low flow causing long delay to
reach wakeup level
• Pressurize pipe and then check for leaks
• Increase wake times
[ADV2-48] to [ADV2-51] . Run system between different load demands and record
Last Wake Time [ADV2-47] for each run. Set wake times larger than recorded value.
