-In a single ​unit systemturn the unit '​off'​ on the front panel rocker switch and apply AC input power. Measure the AC output. If AC voltage is present, the unit is faulty ​(stuck relay).+In a single ​phase installation with two or more devices in parallelor a three-phase installation with six or more devicesit can be difficult to identify ​the unit that is faulty ​because all units in at the relevant group of units will raise 'Error 24'
  
-In a three-unit, three-phase cluster ​(only one unit per phase), the faulty unit can be identified ​in the same way. As for the single ​unit case, any unit presenting ​AC output voltage when the rocker ​switch is set to '​off' ​is faulty.+This happens because the faulty ​unit will be (incorrectlysupplying AC energy on it output at times when it should not be - including when its front panel rocker switch is set to '​off'​When energy from the faulty unit's AC output flows in to the other unit(s) via their AC outputs, this causes these other units to be (incorrectly) flagged for 'Error 24' by the system self-test. The units concerned may also be '​buzzing'​ in the presence of AC power at their inputs with their rocker ​switches ​set '​off'​.
  
-You can also determine the faulty ​unit(s) by just listening for units that are //audibly humming// while their front panel rocker switch ​is set '​off'​. ​The humming is because ​AC power is being applied to the internal circuitry when it should ​not be.+To help identify which unit is faulty in this scenario, first un-wire the AC outputs of all the units concerned to prevent cross-feeding of AC energy via the AC outputs. Then apply AC power with all units still set to '​off' ​on their front panel rocker switchesMeasure the AC output terminals with a meter - the faulty unit is the one that is still presenting AC voltage on its output terminals. If this approach is not successful, try turn turning the units '​On'​ and look for which unit now presents 'Error 24' in isolation
  
-Where there are multiple units hardwired in parallel (a multi-unit/​single phase systemor a three-phase cluster with 6 or more units), then there is an additional diagnostic challenge. In these systems, the faulty unit will be feeding energy out from its AC output ​and this energy will then flow into to the other (good) units via their respective ​AC output terminals. ​This results in //all// units that are parallel-wired appearing ​to be faulty, and all units concerned humming while set to '​off'​.+If this is not conclusivetry completely disconnecting all suspect ​units from all AC and DC sources. With an ohm-metermeasure ​the resistance between the neutral terminals on AC input and the AC output, A working unit will show no connection between these terminals. ​A faulty unit may show a connection ​to be present between these terminalswith either zero resistance or potentially with a small a non-zero (and non-normal) resistance present.
  
-The most conclusive way to determine which unit is faulty in this case is to un-wire the AC outputs of all the units concerned to prevent the cross-feeding of AC energy via the AC outputs. Then apply AC power with all units still set to '​off'​ on their front panel rocker switches. The faulty unit is the one that is still humming and that is still presenting AC voltage on its output terminals.
