Problem Solution
No reading at controller • Check operation (see above)
• Check for control voltage at sensor (<30V, <1A)
• Check for amperage in monitored conductor (> threshold)
• Assure that sensor core mating surfaces are clean and that the core clamp is completely closed
Status outputs incorrect If the status outputs are not seen as described above, the ECM may have “keep alive current” greater
than the current sensor threshold. Record the actual AC supply current flow to the ECM when the motor
is not rotating (a current measurement device may be needed). This is called the “keep alive current”.
For most ECM products, this is less than 0.5A. If the current seen is greater than the threshold, contact
Veris Customer Support. A higher setpoint current monitoring switch product may be needed.
1. Issue a command to the ECM to rotate at normal operation speed and confirm that the motor shaft is rotating.
2. The status output of the H6ECM series product should be CLOSED (conductivity exists between terminals).
3. Issue a command to the ECM to stop rotation and confirm that the motor shaft is not rotating.
4. The status of the H6ECM series product should be OPEN (no conductivity exists between terminals).
