AUTO ZERO
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). The E9
error is cleared after five seconds.
If material feed resumes during an auto zero function, the totalizing
function is maintained.
COMMUNICATION
The BW100 bipolar current loop provides long distance communication to an RS-232
or RS-422 device via a local Milltronics CVCC or BIC-2 interface.
* maximum 6 BW100 per BIC-2
The BW100 communication port (TB1-21 to 25) is software set for baud (P751) and
mode enable (P760). Refer to Installation\Communication for wiring details.
If communicating via Milltronics Dolphin software,
the baud rate must be set to ’4800’.
