Placing the internal totalizers on to the display scroll of the RUN mode is controlled by the totalizer display parameter (P647); displaying either one or both totalizers. Auto Zero Operation The Auto Zero function allows a zero calibration to be initiated automatically under the following conditions. • the auto zero input (TB1-9/10) is in a closed state; jumper or remote switch • the load is less than 2% of the design load If the resulting zero deviation is less than an accumulated 2% from the last operator initiated zero, the auto zero is accepted.
If the deviation is greater than an accumulated 2%, an E9 error is displayed and the relay, if so programmed, goes into alarm (refer to Operation/Relay Output, page 44). The E9 error is cleared after five seconds. If material feed resumes during an auto zero function, the totalizing function is maintained. Page 46 Milltronics BW100 - INSTRUCTION MANUAL 7ML19985DJ01
