STOP END OF CYCLE / CONTINUE switch
This is the switch that you should use to STOP the system. This switch is wired in series
with the level sensor. Turning it off breaks the signal to the computer the same as covering
the level sensor with material. This stops the process at the end of a full cycle.
IMMEDIATE PAUSE / CONTINUE switch
Causes a computer-controlled immediate pause during a cycle. Dispenses will stop in mid-
dispense if necessary. When switched back to CONTINUE, the process continues without
any error in amounts dispensed.
A cycle can be aborted during an Immediate Pause by pressing the DUMP button.
RS-232, RS-485 Communication Port
Serial has been the standard method of communications until the introduction of the 12–12
Controller, when onboard Ethernet became available. For customers who have been using
Serial for their communications, this option is still implemented as before making the
controller backward compatible with earlier Maguire Weigh Scale Blender communication
serial networks. The SERIAL port is a DB9 (9 pin) male port that communicates the MLAN
protocol over RS-232 and RS-485. The serial port is also used to convert MLAN protocol
over serial to other industrial protocols using a third party gateway.
ETHERNET PORT (RJ-45)
The Ethernet port allows for communication to the controller over Ethernet. Communication
through this port is TCP/IP utilizing the MLAN Protocol or Modbus. The G2 Software, using
the MLAN Protocol, can communicate with the controller over Ethernet using this Ethernet
port.
For information on configuring the Ethernet interface, see Communications.
SILENCE ALARM
This button stops the STROBE and BEEPER ALARMS, but does not remedy
the cause of the alarm. The continuation of the cycle to its proper completion
will also stop the alarm. When in the BATCH mode, this button also serves to
start the next batch.
