Operator Controls
Two devices provide operator interface; they are the
Operator Station , located in the spray booth, and the
Keypad , located on the control.
Operator Station
The Operator Station consists of an Operator Switch
and a Report Button . See Fig. 7.
Operator Switch
There are three operator switch input settings: mix,
standby, and purge.
Mix
Set the operator switch to mix to start normal operation
(mixing and dispensing) of the system.
Standby
Set the operator switch to standby to stop the system.
Purge
Set the operator switch to purge the system. The
solenoid outputs signal the system to cycle between
the air and solvent purge valves.
NOTE: Purge will not start until two seconds after the
operator switch has been moved to the purge position.
This two second delay allows time to turn the switch to
clear an alarm; see
Clearing Alarms , below.
Clearing Alarms
All alarms, except the Pot Life Alarm, can be cleared
by moving the operator switch from mix to standby to
purge to standby. See page 28 for information on
alarms. Turn to mix to resume operation after clearing
the alarm.
Report Button
If a printer is connected to the control, press the report
button to generate a report from the printer. This also
clears the A and B totalizer.
