8. STROBE LIGHT AND BEEPER ALARMS
The Strobe light flashes and the Beeper sounds when a component fails
to meter properly. Alarms begin after a number of retries have
occurred, this number determined by the parameter table (see
Parameters, _AL). These alarms can also indicate an out-of-range TARE
weight. This range is set by the TL and TH parameters; above 100 or
below -50 grams.
9. ALARM SILENCE
This button stops the STROBE and BEEPER ALARMS. 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.
10. LEVEL SENSOR input
The high level sensor in the mixing chamber plugs into this outlet and
signals the controller to start a dispense cycle when it is uncovered.
The sensor must be uncovered for at least 2 seconds before a cycle will
start (see DLY 00488 Parameter). Once a dispense cycle is started,
covering the sensor does not stop it. Operation continues until the
cycle is complete.
