Applicable Pressure switch: ZK2-ZSV-A
If an operational failure of the pressure switch occurs, please select the cause of failure from the flow chart
below.
If a cause applicable to the failure cannot be identified and normal operation can be recovered by
replacement with a new pressure switch, this indicates that the pressure switch itself was faulty.
The damage to the pressure switch may have been caused by the operating environment (network
construction, etc.). Consult with SMC separately to obtain countermeasures.
