8. Troubleshooting

1. Please check if the ZM-MFC1 Combo is properly connected to the PSU.

2. Please check that all cables have been properly connected.

3. Please check Fan speciﬁcations.

1) 2-Pin Fans that do not output a voltage signal cannot be used. 3-Pin Fans with 2 clock pulses

per revolution must be used.

2) If a 3-Pin Fan is connected to a 4-Pin Connector, RPM control will not function properly.

4. If there is a malfunction with the Fan, the RPM clock signal will be disrupted and RPM control will

not function properly.

5. If the fan has a minimum threshold RPM, setting the RPM below this threshold will cause the Fan

to intermittently start and stop. Set the fan RPM above the minimum required threshold RPM to

prevent malfunction.
