Milltronics COMPU-M User Manual

Analog mA Output
This dc current output is proportional to the current rate of material throughput and may be utilized for
operating external process monitoring and/or process control equipment. The minimum output corresponding
to minimum (usually 0) rate is user selectable (P12) for 0 or 4 mA. The maximum output corresponding to
maximum desired rate is 20mA. The analog mA output may be stabilized by the damping values entered in
P11 or P18.
Remote Totalizer Contact
The Compu-M provides a relay contact closure which may be utilized to operate an external device such as a
remote totalizer. The on-time duration of the relay contact closure is operator selectable (P16) to suit the
external device connected.
Alarm
The Compu-M provides a programmable relay for alarm (P20) on material rate, belt speed or auto zero out of
range. If enabled, the relay is energized under normal operation. Under alarm condition, the relay is
de-energized and the display flashes. Upon return to normal operation, the alarm state is cleared and the
relay energized. If the relay is programmed for auto zero the alarm is in effect until an auto zero within range
occurs, when a calibration is initiated or when the rate exceeds 12% of design.
The relay contacts are accessed via board A, TB2.
INITIAL START UP
When working on a belt scale, ensure that the conveyor is stopped and locked out.
Once installation, interconnection and internal checks have been completed, apply power to the Compu-M.
The display should read,
