The first thing to check when you encounter a fault is the physical space, check failed lights, poor wiring, good weather protection. Next, confirm that you are running the most current version. If the PHD is safe and secure, your firmware is current so use the following information to help resolve any faults.
PHD Fault Codes
Fault codes are found in the ST Chn in the data dictionary of the PHD. When a PHD is at fault, your lights may not function properly, it is important to clear the fault.
102: Current Overload (Digital Limit)
Description: Drawing too much current 4.2 Amps
Resolution: ask Amatis to increase current trip SP (4,5,10)
103: Current Trip (Analog Limit)
Description: Drawing too much current at On.
Resolution: Fix the light or turn off this feature. Ask Amatis to increase current trip SP (4,5,10)
104: Voltage High
Description: Positive voltage is out of range
Resolution: Reboot mcba and if the issue persists RMA the PHD
105: Voltage Low
Description: Negative voltage is out of range
Resolution: Reboot mcba and if the issue persists RMA the PHD
106: Current Mismatch (high low)
Description: Plus and minus currents do not match (1A threshold)
Resolution: Reboot mcba and if the issue persists RMA the PHD
107: Parallel (Stray voltage on channel)
Description: Foreign voltage or paralleled positive outputs found on startup test.
Resolution: Reboot mcba and if the issue persists RMA the PHD
108: Stuck
Description: Unable to turn off positive voltage on startup (shorted FET or foreign voltage) -> RMA
Resolution: Reboot mcba and if the issue persists RMA the PHD
109: Lockout
Description: Channel fail / retry count exceeded.
Resolution: Reboot mcba and if the issue persists RMA the PHD
110: System (bus under/over voltage)
Description: Bus under or overvoltage etc.
Resolution: Reboot mcba, RMA (mean well fail?)
111: Short Circuit
Description: PSM could not raise output voltage during the initial inrush pulse train
Resolution: Reboot mcba, check the wiring
112: Power Overload
Description: Digital power measurement exceeded setpoint (normally 99VA)
Resolution: ask Amatis to increase current trip SP (4,5,10)
115: Fault out of range
Resolution: turn the channel on by writing 1100
255: Fault out of range
Resolution: turn the channel on by writing 1100
