Interrupters User Guide
Appendix D: Mercury Relay Advisory

2.
If fast cycle operation is common, AI recommends a solid state relay for maximum life and
reliability.
Although most interrupters are capable of being programmed for faster interruption cycles, AI
recommends that customers not exceed 900 cycles per hour (or a cycle time of less than four
seconds) and will not warranty devices that are utilized in this manner. AI adds a serial number to
relays that is supplied that we supply to enable the tracking of the shipment date. The approximate
age of the relay may be used to assist AI in return material response, failure analysis, and warranty
claims. Manufacturers will be consulted to help determine failure cause and to advise customers that
warranties may not be honored if it is deemed that the mercury relay is used outside of
recommended parameters.
