Page 9: Additional Hardware Required
SYSTEM - 40 BTU MEASUREMENT SYSTEM 1.5 ADDITIONAL HARDWARE ONICON’S System-40 is a true heat (BTU) computer, which accepts data from REQUIRED several sensors, performs a series of computations with that data, and displays and/or transmits the results as an indication of the amount of heat (BTU) being transferred per unit time or as a totalized amount. -
Page 10: Section 3.0 Installation
Meters installed with reversed flow will not function. • The System-40 is provided with fixed cable lengths for the flow sensor and temperature sensors. Do not alter the cable lengths. Doing so will void the calibration and may invalidate the warranty. -

** Count available in System-40 diagnostic menu page 2. Description of Sub-functions: 00 Return Query Data The data passed to the System-40 in the request data field is to be returned (looped back) in the response. The entire response message should be identical to the request. - Page 57 18 (12 Hex) Return Bus Character Overrun Count The response data field returns the quantity of messages addressed to the System-40 that it could not handle due to a character overrun condition, since its last restart, restart communications option, or power-up. A character overrun is caused by data characters arriving at the port faster than they can be stored, or by the loss of a character due to a hardware malfunction.
