The following 6000 Series products:
- APEX 615n
- ZETA 61nn
all incorporate battery backed RAM to store programs, variables, and parameter settings, and use the same 3V, Sanyo-type CR2450 battery to store this information in the controller's memory. Replacement batteries do not necessarily have to be a Sanyo product (Panasonic batteries can also be used), but it does need to be of the "CR2450" battery type.
While Compumotor does not maintain a stock of replacement batteries for individual purchase, you can purchase these batteries at most local electronic and/or camera stores. Please contact the Compumotor Applications Department at 1-800-358-9070 for information about replacing the battery in your 6K or 6000 product.
NOTE: While the battery, which sustains the memory for the 6K and 6000 Series products, has a typical lifespan of several years, they can dissipate over shorter periods of time - especially if the 6K or 6000 product is left unpowered for an extended period of time. If storing the aforementioned Compumotor products for any lengthy duration, occasionally power up the devices to preserve the battery - and the stored programs and parameter settings of your unit.
