As a rule, SMC will not conduct on-site maintenance. Separately, the following parts have a limited life and need to be replaced before the life ends. Maintenance Alarm output connector D-sub 9 pin (male type) Communication connector D-sub 9 pin (female type) Connectors that fit with a communication connector and an alarm output connector should be prepared by customer. Description Circulating pump Fan DC power supply The circulating fluid cannot be fed due to worn bearing and/or insufficient capacity of electrolytic capacitor, which results in temperature controlling failure. The capacity of the fan lowers due to the end of lubricating performance of the bearing, which results in increase of internal temperature of the Controller. The overheat protective function at the inside of the power supply starts, the output stops and the display goes off. Abnormal voltage is generated and the display goes off due to insufficient capacity of electrolytic capacitor. 3 to 5 years 5 to 10 years 5 to 10 years Expected life Possible failure Parts Life Expectation Peltier-Type/Thermoelectric Bath Series HEB 1419 HRG HRS HRZ HRZD HRW HEC HEB HED HEA IDH
